Hyaluronic Acid

Hyaluronic acid is the key to supple and hydrated skin. This popular skin care ingredient is a moisture-binding humectant capable of holding 1,000 times its weight in water. Hyaluronic acid is found naturally in the body but its production decreases as we age. This is where hyaluronic acid skin care products come in! When applied topically on skin, hyaluronic acid hydrates skin and helps reduce the appearance of fine lines and wrinkles. It comes in different types – hydrolyzed hyaluronic acid, sodium hyaluronate and sodium acetylated hyaluronate – and different molecular weights. High-molecular-weight hyaluronic acid hydrates the surface of skin, while low-molecular-weight hyaluronic acid penetrates deeper into skin. Many products are formulated with a mix of different hyaluronic acids to maximize the benefits of this powerful hydrator.

Suitable for all skin types including sensitive skin, hyaluronic acid fits easily into any skin care routine. Hyaluronic acid is best applied after using a toner, as it can easily attract moisture and boost skin’s moisture levels. Remember to follow with a moisturizer to lock in hydration! Finding the right hyaluronic acid product depends on your skin type and skin needs. YesStyle offers a wide range of hyaluronic acid serums as well as hyaluronic acid-infused products like toners, creams and masks that deliver various skin care benefits.

About Hyaluronic Acid & Benefits

What is hyaluronic acid?

Hyaluronic acid is a substance that occurs naturally in the human body, acting as a lubricant mainly around the joints and eyes. This moisture-binding humectant has the ability to attract and retain water. Hyaluronic acid can retain as much as 1,000 times its weight in water, making it one of the best hydrators for skin. Our body’s supply of hyaluronic acid decreases as we age, so this humectant is an in-demand ingredient in skin care. Hyaluronic acid in skin care products can be sourced in two ways: derived from rooster combs or through bio-fermentation in labs, which is the vegan-friendly method.


How many types of hyaluronic acid are there?

There are three types of hyaluronic acid: hydrolyzed hyaluronic acid, sodium hyaluronate and sodium acetylated hyaluronate. Hydrolyzed hyaluronic acid is most suitable for oily and combination skin types as it hydrates the skin’s surface when applied topically. Sodium hyaluronate is a derivative of hyaluronic acid whereby the sodium (a.k.a. salt) content is extracted from pure hyaluronic acid. The salt form of this ingredient is more stable and less likely to oxidize. Smaller in particle size than hydrolyzed hyaluronic acid, sodium hyaluronate penetrates deep into skin more easily. It’s perhaps the most common form of hyaluronic acid found in skin care products. Sodium acetylated hyaluronate, known as super hyaluronic acid, is best suited for people who have dry and severely dehydrated skin in need of intense and long-lasting moisture. With higher moisture-binding abilities, super hyaluronic acid is an especially popular form of hyaluronic acid for anti-aging skin care.


What are the benefits of hyaluronic acid?

Capable of holding 1,000 times its weight in water, hyaluronic acid is in high demand in the world of skin care. It acts like a magnet, drawing moisture from wherever possible to hydrate skin. This gel-like substance leaves skin robustly moisturized, plump and soft. For those concerned with skin aging, hyaluronic acid can reduce the appearance of fine lines and wrinkles. Those with dry and dehydrated skin would reap the most benefits from using this ingredient as it’s capable of boosting moisture levels. Hyaluronic acid also speeds up wound repair and healing.


What skin types are most suitable for hyaluronic acid?

Some people may hesitate to use anything with the word “acid” in it, but hyaluronic acid is one of the safest skin care ingredients. It works well for all skin types, even sensitive skin. As this humectant is known for its hydrating and moisturizing properties, it’s most suited for those with dry and dehydrated skin.


What does different molecular weight hyaluronic acid mean?

Not all hyaluronic acids are created equal. The low-molecular-weight form of hyaluronic acid penetrates deep into skin to reach the epidermis, but it binds less water. High-molecular-weight hyaluronic acid binds more water, but it can only hydrate the surface of skin. Those with extremely dry skin should look for the low-molecular-weight variety to deeply hydrate skin.


What should I look for when shopping for hyaluronic acid skin care products?

Before buying a hyaluronic acid product, it’s good to understand what you’re getting. Most hyaluronic acid products are not pure, as they’re engineered to come in smaller-sized particles that effectively penetrate into skin. Hyaluronic acid makes up about one to two percent of the formula because anything more will have drying effects on skin. The remainder of the content is most likely water. For optimal results, look for hyaluronic acid products that come in a variety of molecular sizes, though not all products will indicate the molecular weight of hyaluronic acid used.


How do you use hyaluronic acid?

In your skin care routine, hyaluronic acid can be applied both morning and night right after cleansing and applying toner. This is the best time to apply hyaluronic acid, because your skin is moist, making it easier for hyaluronic acid particles to draw in and preserve moisture. Hyaluronic acid is commonly used in serums; two to three drops of hyaluronic acid serum would suffice. Follow with a facial oil or moisturizer to seal in the moisture.


Hyaluronic acid normally doesn’t react negatively when combined with other skin care products. Its lightweight and watery consistency feels refreshing on skin when applied on its own or with other products. Hyaluronic acid works well when combined with an antioxidant-rich Vitamin C product in the morning skin care routine, like NEOGEN’s Dermalogy Real Vita C Serum. It also pairs well with glycolic acid in the evening skin care routine, like COSRX’s AHA 7 Whitehead Power Liquid which helps revitalize skin and boosts collagen production.


Are there side effects when using hyaluronic acid?

Hyaluronic acid is not known to have adverse effects on skin when used correctly. However, make sure to only use products formulated with not more than two percent of this ingredient. Applying too much hyaluronic acid can have the counter effect of drying out skin. Hyaluronic acid works by drawing moisture from wherever it can. If too much hyaluronic acid is applied, or if it is applied to dry skin in a dry climate, it will draw moisture from the deeper layers of skin.


What are popular hyaluronic acid brands and products?

Hyaluronic acid can be offered as a standalone ingredient, but it’s most commonly infused with other ingredients to provide various skin benefits. Choosing a product containing this humectant depends on what your skin needs.


Elizavecca’s Milky Piggy Hyaluronic Acid Pure 100 and Cos De BAHA’s HS Hyaluronic Acid Serum are popular for being simple formulations consisting of only sodium hyaluronate and water. For those who need something strong to remedy dry skin, MIZON’s Hyaluronic Acid 100 is a great option as it contains ceramide to strengthen skin’s moisture barrier.


For those who want to brighten a dull complexion while hydrating skin, consider iUNIK’s gel-type Vitamin Hyaluronic Acid Vitalizing Toner, which combines niacinamide and hyaluronic acid to deliver hydrating and brightening benefits. For those dealing with sensitive skin, try Dear, Klairs’s Rich Moist Soothing Serum, a vegan-friendly formula that moisturizes skin while delivering skin-calming effects. After using toner and serum in your skin care routine, lock in all the goodness with a facial moisturizer, like COSRX’s Hyaluronic Acid Intensive Cream.

ヒアルロン 酸とは?

ヒアルロン酸は人間の体内に元々存在するゼリー状の物質で、主に関節や目の周りの潤滑油として機能しています。水分と結合するこの保湿成分には、水を引き寄せて保持する能力があります。ヒアルロン酸は、重量の1,000倍もの水を保持することができ、肌にとって最高の保湿成分の1つです。加齢とともに減少するので定期的な補給が必要です。スキンケア製品に含まれるヒアルロン酸には、オンドリの櫛から採取する方法と、実験室でバイオ発酵させる方法があります。


ヒアルロン酸には何種類ありますか?

ヒアルロン酸には、加水分解ヒアルロン酸、ヒアルロン酸ナトリウム、アセチル化ヒアルロン酸ナトリウムの3種類があります。加水分解ヒアルロン酸は、局所的に塗布することで肌表面に水分を与えるため、オイリー肌や混合肌のタイプに最も適しています。ヒアルロン酸ナトリウムは、純粋なヒアルロン酸からナトリウム(別名:塩)分を抽出したヒアルロン酸の誘導体であり、この成分の塩の形は、より安定しており、酸化しにくいです。加水分解ヒアルロン酸よりも粒子が小さく、肌の奥まで浸透しやすいのが特徴です。スキンケア製品に配合されているヒアルロン酸の中では、最も一般的な成分と言えます。スーパーヒアルロン酸と呼ばれるアセチル化ヒアルロン酸ナトリウムは、乾燥肌や重度の脱水肌で、濃厚な潤いを長時間持続させたい人に最適です。スーパーヒアルロン酸は、より高い水分結合能力を持ち、アンチエイジングのためのスキンケアには特に人気のあるヒアルロン酸です。


ヒアルロン酸のメリットは?

体重の1,000倍の水を蓄えることができるヒアルロン酸は、スキンケアの世界では非常に重要な存在です。ヒアルロン酸は磁石のようにあらゆるところから水分を引き寄せ、肌に潤いを与えます。このゼリー状の物質は、肌にしっかりとした潤いを与え、ふっくらとした柔らかい肌にしてくれます。肌の老化が気になる方には、ヒアルロン酸は小じわを目立たなくする効果があります。肌の乾燥が気になる方には、水分量を増やす効果のあるヒアルロン酸の使用が効果的です。また、ヒアルロン酸は傷の修復や治癒を早めてくれます。


どのような肌タイプの人がヒアルロン酸に適していますか?

「酸」とつくものは使うのをためらう人もいるかもしれませんが、ヒアルロン酸はスキンケア成分の中でも安全性の高いものです。敏感肌であっても、すべての肌タイプに効果があると言われます。この保湿成分は、水分補給と保湿効果で知られているため、乾燥肌や脱水肌の方に最も適しています。


分子量の違うヒアルロン酸とはどういう意味ですか?

すべてのヒアルロン酸が同じように作られているわけではありません。低分子ヒアルロン酸は、肌の奥深くまで浸透して表皮に届きますが、結合する水の量は少なくなります。高分子ヒアルロン酸は、水との結合力は高いのですが、肌の表面にしか潤いを与えることができません。極度の乾燥肌の方は、肌の奥まで潤う低分子タイプがおすすめです。また、高分子ヒアルロン酸の化粧品は「しっとり」タイプ、低分子ヒアルロン酸の化粧品は「さっぱり」タイプと、使い心地も異なるため、お肌の悩みと合わせて使い心地も自分の好みに合わせて、選びましょう。


ヒアルロン酸のスキンケア製品を購入する際、どのような点に注意すればよいでしょうか?

ヒアルロン酸製品を購入する前に、自分が何を得ようとしているのかを理解するのは良いことです。ほとんどのヒアルロン酸製品は純粋なものではなく、肌に効果的に浸透するように小さいサイズの粒子で作られています。ヒアルロン酸の配合率は1〜2%程度で、これ以上だと肌が乾燥してしまうからです。最適な結果を得るためには、様々な分子サイズのヒアルロン酸製品を探すことですが、すべての製品に使用されているヒアルロン酸の分子量が表示されているわけではありません。


ヒアルロン酸の使い方は?

スキンケアでは、朝晩とも、洗顔後、化粧水をつけた直後にヒアルロン酸を塗布します。この時間帯は肌が潤っていて、ヒアルロン酸の粒子が水分を取り込みやすくなっているので、ヒアルロン酸を塗るのに最適な時間帯です。ヒアルロン酸は一般的に美容液に配合されていますが、ヒアルロン酸美容液は2~3滴で十分です。その後、オイルや保湿クリームで潤いを閉じ込めます。


ヒアルロン酸は通常、他のスキンケア製品と組み合わせてもマイナスの反応はありません。水のように軽く、そのままでも、他の製品と一緒に使っても、肌にさっぱりとした感触を与えてくれます。NEOGENのリアルビタミンC美容液のように、朝のスキンケアで抗酸化作用のあるビタミンC製品と一緒に使うと効果的です。また、夜のスキンケアでは、COSRXのAHA 7ホワイトヘッドパワーリキッドのように、グリコール酸と組み合わせると、肌を活性化させ、コラーゲンの生成を促進します。


ヒアルロン酸を使用する際に副作用はありますか?

ヒアルロン酸は、正しい使い方をすれば、肌に悪影響を及ぼすことは知られています。ただし、ヒアルロン酸の配合量が2%以下の製品を使うようにしてください。ヒアルロン酸をつけすぎると、逆に肌を乾燥させてしまいます。ヒアルロン酸は、どこからでも水分を吸い上げる働きがあります。ヒアルロン酸を塗布しすぎたり、乾燥した気候で乾燥した肌に塗布したりすると、肌の深層部から水分を奪ってしまいます。


人気のあるヒアルロン酸のブランドや商品は?

ヒアルロン酸は単体でも提供されますが、様々な肌効果を得るために他の成分と一緒に配合されることがほとんどです。この保湿成分を含む製品を選ぶには、肌が何を必要としているかによります。


Elizaveccaのミルキーピギー ヒアルロン酸100%美容液や、COS DE BAHAのHSヒアルロン酸美容液は、ヒアルロン酸Naと水だけのシンプルな処方で人気があります。乾燥肌を改善するために強力なものが必要な方には、セラミドを配合し、肌の水分バリアを強化するMIZONのヒアルロン酸100美容液がお勧めです。


肌に潤いを与えながら、くすんだ顔色を明るくしたい方には、ビタミンB3とヒアルロン酸を配合し、潤いと明るさを与えるiUNIKのジェルタイプのビタミンヒアルロン酸バイタライジング化粧水をお勧めします。敏感肌やオイリー肌の方には、Dear, Klairsのリッチモイストスージング美容液が、乾燥した肌に潤いを与えて落ち着かせます。化粧水と美容液を使ってスキンケアをした後は、COSRXのヒアルロン酸インテンシブクリームのような保湿クリームで全ての良さと水分を閉じ込めましょう。

Qu'est-ce que l'acide hyaluronique ?

L'acide hyaluronique est une substance naturellement présente dans le corps humain, qui agit comme un lubrifiant principalement autour des articulations et des yeux. Cet humectant a la capacité d'attirer et de retenir l'eau. L'acide hyaluronique peut retenir jusqu'à 1000 fois son propre poids en eau, ce qui en fait l'un des meilleurs hydratants pour la peau. La quantité d'acide hyaluronique présente dans le corps diminue avec l'âge. Cet humectant est donc un ingrédient de soin du visage très prisé. Il existe deux méthodes pour obtenir l'acide hyaluronique présent dans les produits de soin : l'acide hyaluronique dérivé de la crête de coq, ou bien obtenu par bio-fermentation en laboratoire. Cette seconde méthode est végane.


Combien de types d'acide hyaluronique existe-t-il ?

Il existe trois types d'acide hyaluronique : l'acide hyaluronique hydrolysé, l'hyaluronate de sodium et l'hyaluronate de sodium acétylé. L'acide hyaluronique hydrolysé est le mieux adapté aux peaux mixtes à grasses, car il hydrate la peau en surface lorsqu'il est appliqué localement. L'hyaluronate de sodium est un dérivé de l'acide hyaluronique dans lequel le sodium (ou sel) est extrait de l'acide hyaluronique pur. La forme salée de cet ingrédient est plus stable et moins sujette à l'oxydation. Grâce à ses particules plus fines que celles de l'acide hyaluronique hydrolysé, l'hyaluronate de sodium pénètre plus facilement la peau en profondeur. Il s'agit probablement de la forme d'acide hyaluronique la plus courante dans les produits de soin du visage. L'hyaluronate de sodium acétylé, également connu sous le nom de « super acide hyaluronique », est le mieux adapté aux peaux sèches et particulièrement déshydratées, qui requièrent une hydratation intense et longue durée. Grâce à ses meilleures capacités de rétention de l'hydratation, le super acide hyaluronique est une forme d'acide hyaluronique particulièrement prisée dans les soins anti-âge et anti-rides.


Quels sont les bienfaits de l'acide hyaluronique ?

Capable de retenir jusqu'à 1000 fois son propre poids en eau, l'acide hyaluronique est un ingrédient très recherché dans la sphère des soins du visage. Il agit comme un aimant pour attirer l'hydratation de toutes les sources possibles afin d'hydrater la peau. Sa texture de type gel laisse la peau intensément hydratée, douce et repulpée. Pour les personnes en quête d'un soin anti-âge, l'acide hyaluronique permet de réduire l'apparence des rides et des ridules. Les peaux sèches et déshydratées sont celles qui bénéficient le plus des bienfaits de cet ingrédient, car il permet avant tout de booster le niveau d'hydratation de la peau. L'acide hyaluronique aide également à accélérer le processus de cicatrisation des plaies.


L'acide hyaluronique : pour quels types de peaux ?

Même si le mot « acide » peut faire peur à beaucoup, l'acide hyaluronique est en fait l'un des ingrédients de soin les plus sûrs d'utilisation. Il convient à tous les types de peaux, même les plus sensibles. Cependant, puisque cet humectant est essentiellement connu pour ses propriétés hydratantes, il est particulièrement recommandé pour les peaux sèches et déshydratées.


Que signifie le poids moléculaire de l'acide hyaluronique ?

Tous les acides hyaluroniques ne sont pas égaux en termes de poids moléculaire. L'acide hyaluronique de faible poids moléculaire pénètre la peau en profondeur pour atteindre l'épiderme, mais il retient moins d'eau. L'acide hyaluronique de poids moléculaire élevé retient plus d'eau, mais n'hydrate la peau qu'en surface. L'acide hyaluronique de faible poids moléculaire est notamment préconisé pour hydrater en profondeur les peaux extra-sèches.


Comment bien choisir ses produits à l'acide hyaluronique ?

Avant d'investir dans un produit à l'acide hyaluronique, il est important de comprendre ce que vous achetez. La plupart des produits à l'acide hyaluronique ne sont pas purs, car ils sont formulés sous forme de particules plus fines, qui pénètrent la peau plus efficacement. L'acide hyaluronique ne représente qu'environ 1 à 2 % de la formule, car une concentration plus importante aurait des effets asséchants sur la peau. Le reste du produit est composé principalement d'eau. Pour un résultat optimal, tournez-vous vers des produits contenant des acides hyaluroniques de poids moléculaires variés. Cependant, il est à noter que tous les produits n'indiquent pas forcément le poids moléculaire de l'acide hyaluronique qu'ils contiennent.


Comment utiliser l'acide hyaluronique ?

L'acide hyaluronique peut être appliqué aussi bien lors de votre routine de jour que de nuit, juste après le nettoyage et l'application du tonique. C'est en effet la meilleure étape pour l'application de l'acide hyaluronique, puisque votre peau est humide, ce qui facilite l'absorption et la rétention par la peau de l'hydratation et des particules d'acide hyaluronique. L'acide hyaluronique est communément utilisé dans les sérums ; deux à trois gouttes de sérum à l'acide hyaluronique suffisent. Terminez ensuite avec l'application d'une huile pour le visage ou d'une crème hydratante, pour capturer l'hydratation au sein de votre peau.


Vous pouvez généralement combiner l'acide hyaluronique à d'autres produits de soin sans provoquer de réactions négatives. Sa texture légère et aqueuse laisse un effet rafraîchissant sur la peau, que vous l'utilisiez seul ou combiné à d'autres produits. L'acide hyaluronique fonctionne particulièrement bien dans une routine de jour, lorsqu'il est combiné à un produit à la vitamine C riche en antioxydants tel que le sérum à la vitamine C Real Vita C Dermalogy de chez NEOGEN. Il fonctionne également très bien en synergie avec l'acide glycolique dans une routine de nuit, comme avec la lotion puissante anti-boutons à l’AHA de chez COSRX, qui aide à revitaliser la peau et booste la production de collagène.


L'acide hyaluronique a-t-il des effets secondaires ?

Lorsqu'il est utilisé correctement, l'acide hyaluronique n'est pas connu pour avoir des effets indésirables sur la peau. Cependant, veillez bien à n'utiliser que des produits dont la concentration en acide hyaluronique ne dépasse pas les 2 %. L'acide hyaluronique utilisé en trop grande quantité peut avoir l'effet exactement inverse de celui recherché, et assécher la peau. En effet, l'acide hyaluronique fonctionne en puisant l'hydratation de toutes les sources possibles. Par conséquent, si vous appliquez de l'acide hyaluronique en trop grande quantité, ou si vous l'appliquez sur peau sèche sous un climat sec, il puisera l'hydratation des couches profondes de votre peau.


Quels sont les marques et les produits à l'acide hyaluronique les plus populaires ?

L'acide hyaluronique peut être utilisé comme seul ingrédient, mais il est plus communément mélangé à d'autres ingrédients, afin d'offrir des bienfaits variés. Choisissez un produit contenant cet humectant en fonction des besoins de votre peau.


Le sérum à l'acide hyaluronique pur (100 %) Milky Piggy de chez Elizavecca et le sérum à l'acide hyaluronique HS de chez Cos De BAHA sont réputés pour leurs formules simples, composées exclusivement d'hyaluronate de sodium et d'eau. Si vous avez besoin de quelque chose de plus fort pour soulager votre peau sèche, le sérum à l'acide hyaluronique (100 %) de chez MIZON est un excellent choix, car il contient du céramide pour renforcer la barrière d’hydratation naturelle de la peau.


Si vous cherchez plutôt à illuminer un teint terne tout en hydratant votre peau, vous pouvez opter pour le tonique revitalisant et vitaminé à l'acide hyaluronique et à la texture de type gel de chez iUNIK, qui combine acide hyaluronique et niacinamide pour hydrater et illuminer la peau. Enfin, si vous avez la peau sensible, n'hésitez pas à tester le sérum apaisant Rich Moist de chez Dear, Klairs, dont la formule végane hydrate la peau tout en l'apaisant. Et après l'application du tonique et du sérum, capturez-en tous les bienfaits à l'aide d'un soin hydratant tel que la crème intensive à l'acide hyaluronique de chez COSRX !


Was ist Hyaluronsäure?

Hyaluronsäure im menschlichen Körper ist eine natürliche Substanz, die hauptsächlich in den Gelenken und Augen als Gleitmittel wirkt. Dieses feuchtigkeitsbindende Feuchthaltemittel hat die Fähigkeit, Wasser anzuziehen und zu speichern. Hyaluronsäure kann das 1.000-fache ihres Gewichts an Wasser speichern und ist damit einer der besten Feuchtigkeitsspender für die Haut. Die körpereigene Produktion von Hyaluronsäure nimmt jedoch mit zunehmendem Alter ab, daher ist dieses Feuchthaltemittel im Bereich der Hautpflege ein gefragter Inhaltsstoff. Hyaluronsäure in Hautpflegeprodukten kann auf zwei Arten gewonnen werden: Aus Hahnenkämmen oder durch Bio-Fermentation im Labor, welches die vegan-freundliche Methode ist.


Wie viele Arten von Hyaluronsäuren gibt es?

Es gibt drei Arten von Hyaluronsäuren: Hydrolysierte Hyaluronsäure, Natriumhyaluronat und natriumacetyliertes Hyaluronat. Hydrolysierte Hyaluronsäure ist für fettige Haut und Mischhaut am besten geeignet, da sie bei äußerlicher Anwendung die Hautoberfläche hydriert. Natriumhyaluronat ist ein Derivat der Hyaluronsäure, wobei der Natriumgehalt (auch bekannt als Salz) aus reiner Hyaluronsäure extrahiert wird. Die Salzform dieses Inhaltsstoffs ist beständiger und oxidiert weniger wahrscheinlich. Mit kleineren Partikeln als hydrolysierte Hyaluronsäure dringt Natriumhyaluronat leichter und tiefer in die Haut ein. Es ist wahrscheinlich die häufigste Art von Hyaluronsäuren, die in Hautpflegeprodukten vorkommt. Natriumacetyliertes Hyaluronat, auch bekannt als Super-Hyaluronsäure, eignet sich am besten für Menschen mit trockener und stark dehydrierter Haut, die eine intensivere und langanhaltendere Feuchtigkeitsvesorgung für ihre Haut benötigen. Mit höheren feuchtigkeitsbindenden Fähigkeiten ist die Super-Hyaluronsäure hinsichtlich der Anti-Aging-Hautpflege eine besonders beliebte Art der Hyaluronsäure.p>

Was sind die Vorteile der Hyaluronsäure?

Hyaluronsäure kann das 1.000-fache ihres Eigengewichts an Wasser aufnehmen und ist im Bereich der Hautpflege sehr gefragt. Es wirkt wie ein Magnet und zieht Feuchtigkeit wo immer es möglich ist an, um die Haut hydriert zu halten. Diese gelartige Substanz hält die Haut nicht nur gut durchfeuchtet, sondern macht sie auch prall und weich zugleich. Hyaluronsäure ist zudem ein gutes Mittel gegen Anti-Aging, da sie bei Hautalterung das Auftreten von feinen Linien und Fältchen reduzieren kann. Besonders Personen, die mit trockener und dehydrierter Haut zu kämpfen haben, werden mit der Verwendung dieses Inhaltsstoffs am meisten profitieren, da der Stoff in der Lage ist, den Feuchtigkeitsgehalt zu erhöhen. Zudem beschleunigt Hyaluronsäure auch die Wundheilung.


Für welche Hauttypen ist die Anwendung der Hyaluronsäure am besten geeignet?

Manche Leute zögern vielleicht Produkte zu verwenden, die das Wort „Säure“ enthalten, aber Hyaluronsäure ist tatsächlich eine der sichersten Hautpflegestoffe, die es gibt und ist zudem für jeden Hauttyp gut geeignet, sogar für empfindliche Haut. Da dieses Feuchthaltemittel für seine hydrierenden und feuchtigkeitsspendenden Eigenschaften bekannt ist, eignet sich Hyaluronsäure am besten für Personen mit trockener und dehydrierter Haut.


Was hat es mit den verschiedenen Molekulargewichten der Hyaluronsäure auf sich?

Nicht alle Hyaluronsäuren sind gleich aufgebaut. Während die niedermolekulare (kurzkettige) Hyaluronsäure tief in die Epidermis (Oberhaut) eindringt, jedoch weniger Wasser binden kann, kann die hochmolekulare (langkettige) Hyaluronsäure hingegen mehr Wasser binden, aber nur die Hautoberfläche mit Feuchtigkeit versorgen. Personen mit extrem trockener Haut sollten demnach die Variante mit niedrigem Molekulargewicht wählen, um die Haut intensiv mit Feuchtigkeit versorgen zu können.


Was sollte ich beim Kauf von Hautpflegeprodukten mit Hyaluronsäure beachten?

Bevor du ein Hyaluronsäure-Produkt kaufst, solltest du dich am besten vorab über das Produkt informieren. Die meisten Hyaluronsäure-Produkte sind nicht rein, da sie in kleineren Partikeln umgewandelt wurden, um effektiver in die Haut eindringen zu können. Hyaluronsäure macht etwa 1-2 % der Formel aus, da eine höhere Dosis die Haut austrocknen würde. Der Rest des Inhaltsstoffes besteht zum größten Teil aus Wasser. Um optimale Ergebnisse zu erzielen, schau am besten nach Hyaluronsäure-Produkten, die eine Vielzahl von Molekülgrößen aufweisen. Allerdings ist zu erwähnen, dass das Molekulargewicht der Hyaluronsäure nicht immer bei allen Produkten angegeben wird.


Wie ist die Hyaluronsäure anzuwenden?

In deiner Hautpflegeroutine kann Hyaluronsäure sowohl morgens als auch abends direkt nach der Reinigung und nach dem Toner-Schritt aufgetragen werden. Dies ist nämlich der beste Zeitpunkt, da befeuchtete Haut es den Hyaluronsäure-Partikeln erleichtert, die Feuchtigkeit aufzunehmen und zu speichern. Hyaluronsäure wird häufig in Seren verwendet; zwei bis drei Tropfen des Hyaluronsäure-Serums reichen dabei vollkommen aus. Trage anschließend ein Gesichtsöl oder eine Feuchtigkeitscreme auf, um die Feuchtigkeit einzuschließen.


Hyaluronsäure reagiert normalerweise nicht negativ, wenn sie mit anderen Hautpflegeprodukten kombiniert wird. Ihre leichte und wässrige Konsistenz fühlt sich auf der Haut erfrischend an, wenn sie allein oder mit anderen Produkten aufgetragen wird. In der morgendlichen Hautpflege lässt sich Hyaluronsäure gut mit einem antioxidativen Vitamin C-Produkt wie dem Dermalogy Real Vita C Serum von NEOGEN kombinieren. In der abendlichen Hautpflege hingegen funktioniert sie gut mit Glykolsäure enthaltene Produkte, wie zum Beipsiel der AHA 7 Whitehead Power Liquid von COSRX, welches hilft, die Haut zu revitalisieren und die Kollagenproduktion anzukurbeln.


Gibt es bei der Verwendung von Hyaluronsäure Nebenwirkungen?

Nebenwirkungen an der Haut sind bei richtiger Verwendung der Hyaluronsäure nicht bekannt. Nichtsdestotrotz solltest du sicherstellen, dass du nur Produkte verwendest, die mit nicht mehr als zwei Prozent dieses Inhaltsstoffs formuliert sind. Denn das Auftragen von zu viel Hyaluronsäure kann sogar den Gegeneffekt hervorrufen, dass die Haut austrocknet. Hyaluronsäure wirkt, indem sie Feuchtigkeit anzieht, wo immer sie kann. Wird jedoch zu viel Hyaluronsäure verwendet oder in trockenem Klima auf trockene Haut aufgetragen, dann besteht die Gefahr, dass Feuchtigkeit aus den tieferen Hautschichten entzogen wird.


Was sind beliebte Marken und Produkte von Hyaluronsäuren?

Hyaluronsäure kann als eigenständiger Inhaltsstoff angeboten werden, wird jedoch sehr häufig mit anderen Inhaltsstoffen kombiniert, um gleichzeitig mehrere Vorteile für die Haut zu erzielen. Das richtige Produkt auszuwählen, das dieses Feuchthaltemittel beinhaltet, hängt aber auch davon ab, was deine Haut benötigt.


Die Milky Piggy Hyaluronsäure Pure 100 von Elizavecca und das Cos De BAHAs HS Hyaluronsäure-Serum sind für ihre einfachen Formulierungen sehr beliebt, da sie nur aus Natriumhyaluronat und Wasser bestehen. Für diejenigen, die eine stärkere Formel brauchen, um trockener Haut entgegenzuwirken, ist die Hyaluronsäure 100 von MIZON eine großartige Wahl, da sie Ceramid enthält, welche die Feuchtigkeitsbarriere der Haut stärkt.


Für diejenigen, die einen matten Teint aufhellen und gleichzeitig die Haut mit Feuchtigkeit versorgen möchten, sollten den gelartigen Vitamin Hyaluronsäure-Vitalisierungstoner von iUNIK in Betracht ziehen, welcher Niacinamid und Hyaluronsäure kombiniert, um feuchtigkeitsspendende sowie aufhellende Effekte zu erzielen. Für diejenigen, die eine empfindliche Haut haben, sollten hingegen das veganfreundlich formulierte Rich Moist Soothing Serum von Dear, Klairs ausprobieren, welches der Haut Feuchtigkeit spendet und gleichzeitig die Haut beruhigt. Nachdem du den Toner und das Serum während deiner Hautpflegeroutine aufgetragen hast, kannst du zum krönenden Abschluss die wertvollen Inhaltsstoffe mit einer feuchtigkeitsspendenden Gesichtscreme wie die Hyaluronsäure-Intensivcreme von COSRX einschließen.


¿Qué es el ácido hialurónico

El ácido hialurónico es una sustancia que se encuentra de forma natural en nuestro organismo y que actúa principalmente como un lubricante en las articulaciones y los ojos. Este ingrediente humectante tiene la capacidad de atraer y retener hasta 1.000 veces su peso en agua, convirtiéndose así en uno de los mejores hidratantes disponibles el mercado. Dado que la producción de ácido hialurónico de nuestro cuerpo disminuye a medida que envejecemos, su demanda aumenta año tras año en la industria de la cosmética, en particular de los tratamientos de belleza. El ácido hialurónico presente en los productos de cuidado de la piel se obtiene mediante dos métodos: el ácido hialurónico animal se deriva de la cresta de los gallos y el ácido hialurónico vegetal de un proceso de biofermentación.


¿Existen tipos diferentes de ácido hialurónico?

Existen tres tipos de ácido hialurónico: ácido hialurónico hidrolizado, hialuronato de sodio e hialuronato acetilado de sodio. El ácido hialurónico hidrolizado de aplicación tópica es el más adecuado de todos para pieles grasas y mixtas, ya que hidrata la superficie de la piel. El hialuronato de sodio es un derivado del ácido hialurónico mediante el cual el contenido de sodio (también conocido como sal) es extraído del ácido hialurónico puro. La sal de este ingrediente es mucho más estable y tiende menos a oxidarse. Con un tamaño de partícula más pequeño que el ácido hialurónico hidrolizado, el hialuronato de sodio penetra en la piel con mayor profundidad y facilidad. Es quizás la forma más común de ácido hialurónico que se encuentra en los productos para el cuidado de la piel. El hialuronato acetilado de sodio, conocido como ácido súper hialurónico, es adecuado para aquellos con piel seca y severamente deshidratada que busquen una hidratación intensa y duradera. Con una mayor capacidad para retener el agua, el ácido súper hialurónico es particularmente reconocido por sus propiedades antienvejecimiento.


¿Cuáles son los principales beneficios de ácido hialurónico?

Capaz de retener 1.000 veces su peso en agua, el ácido hialurónico tiene una gran demanda en el mundo del cuidado de la piel. Actúa como un imán, extrayendo humedad de donde sea posible para hidratar la piel. Esta sustancia tipo gelatina deja la piel hidratada, suave y rellena. El ácido hialurónico atenúa las arrugas y líneas de expresión en las pieles con envejecimiento prematuro, aumenta el nivel de humedad en las pieles secas y deshidratadas, además de acelerar el proceso de reparación y cicatrización de heridas.


¿Cuáles son los tipos de piel adecuados para el ácido hialurónico?

Algunas personas pueden estar indecisas sobre el uso de cualquier producto que contenga la palabra «ácido», pero el ácido hialurónico es uno de los ingredientes para el cuidado de la piel más seguros. Se adapta perfectamente a todo tipo de piel, incluso la sensible. Como este humectante es conocido por sus propiedades hidratantes, es más adecuado para personas con piel seca y deshidratada.


¿Existen los ácidos hialurónicos de diferente peso molecular?

No todos los ácidos hialurónicos son iguales. La forma del ácido hialurónico de bajo peso molecular penetra profundamente en la piel para llegar a la epidermis, pero retiene menos agua. El ácido hialurónico de alto peso molecular tiene la capacidad de unir más agua, pero solo puede hidratar la superficie de la piel. Se recomienda a aquellos con piel extremadamente seca, el ácido hialurónico de bajo peso molecular para una hidratación completa y duradera.


Cosmética con ácido hialurónico

Antes de comprar un producto con ácido hialurónico, es bueno obtener un poco de información sobre el contenido del mismo. La mayoría de los productos de ácido hialurónico no son puros, ya que están diseñados en partículas más pequeñas que penetran rápidamente en la piel. El ácido hialurónico presente en la fórmula constituye alrededor del uno al dos por ciento, un porcentaje mayor resecará la piel. Lo más probable es que el resto del contenido sea agua. Para obtener resultados óptimos, elige productos de ácido hialurónico que incluyan tamaños moleculares diferentes, aunque no todos los productos indican el peso molecular del ácido hialurónico utilizado.


¿Cómo se usa el ácido hialurónico?

Durante la rutina de cuidado de la piel, el ácido hialurónico se puede aplicar tanto por la mañana como por la noche inmediatamente después de la limpieza y del tónico. Ese es el mejor momento para aplicar el ácido hialurónico, ya que la piel se encuentra húmeda, lo que facilita que las partículas de este ingrediente milagroso absorban y conserven la humedad. El ácido hialurónico se usa comúnmente en sérums; solo debes aplicar dos o tres gotas de sérum con ácido hialurónico. Continua con un aceite facial o una crema hidratante para sellar la hidratación.


El ácido hialurónico en la cara normalmente no reacciona negativamente cuando se aplica junto con otros productos para el cuidado de la piel. Su textura ligera y acuosa aporta una sensación refrescante ya sea usado solo o con otras fórmulas. El ácido hialurónico funciona bien cuando se combina con un producto de vitamina C, rico en antioxidantes, en la rutina de cuidado de la piel por la mañana, como el sérum Dermalogy Real Vita C Serum NEOGEN. También funciona bien con el ácido glicólico en la rutina de cuidado de la piel de noche, como el exfoliante AHA 7 Whitehead Power Liquid COSRX, que revitalizar y estimula la producción de colágeno.


¿Cuáles son los efectos secundarios del ácido hialurónico?

No se conocen los efectos secundarios del ácido hialurónico para la cara cuando se usa correctamente. Sin embargo, debes asegurarte de solo aplicar productos formulados con no más del dos por ciento de este ingrediente. Aplicar un porcentaje mayor de ácido hialurónico puede resecar la piel. El ácido hialurónico actúa extrayendo humedad de donde sea posible, principalmente del ambiente. Si se aplica demasiado ácido hialurónico, o si se aplica sobre la piel seca en un clima seco, extraerá la humedad de las capas más profundas de la piel.


Marcas y productos con ácido hialurónico

El ácido hialurónico puede ser ofrecido como un ingrediente independiente, pero lo común es que se mezcle con otros ingredientes para brindar múltiples beneficios. La elección de un producto que contenga el mejor ácido hialurónico depende de las necesidades específicas de la piel.


El sérum Milky Piggy Hyaluronic Acid Pure 100 Elizavecca y el sérum HS Hyaluronic Acid Serum Cos De BAHA se destacan por sus fórmulas simples que contienen únicamente hialuronato de sodio y agua. Aquellos que buscan algo un poco más fuerte para combatir la resequedad de la piel, pueden optar por el ácido hialurónico Hyaluronic Acid 100 MIZON, cuyo contenido de ceramida, fortalece la barrera de humedad de la piel.


Recomendamos a aquellos que deseen hidratar e iluminar la piel apagada, el tónico en gel Vitamin Hyaluronic Acid Vitalizing Toner iUNIK, que combina niacinamida y ácido hialurónico para brindar beneficios hidratantes y luminosos. Aquellos con piel sensible, pueden utilizar el sérum calmante Rich Moist Soothing Serum Dear, Klairs, cuya fórmula vegana proporciona efectos hidratantes y calmantes profundos. Después del tónico y del sérum, sella todos los beneficios de la rutina de cuidado facial con una buena crema hidratante, como lo es la crema Hyaluronic Acid Intensive Cream COSRX.


What is hyaluronic acid?

Hyaluronic acid is a substance that occurs naturally in the human body, acting as a lubricant mainly around the joints and eyes. This moisture-binding humectant has the ability to attract and retain water. Hyaluronic acid can retain as much as 1,000 times its weight in water, making it one of the best hydrators for skin. Our body’s supply of hyaluronic acid decreases as we age, so this humectant is an in-demand ingredient in skin care. Hyaluronic acid in skin care products can be sourced in two ways: derived from rooster combs or through bio-fermentation in labs, which is the vegan-friendly method.


How many types of hyaluronic acid are there?

There are three types of hyaluronic acid: hydrolyzed hyaluronic acid, sodium hyaluronate and sodium acetylated hyaluronate. Hydrolyzed hyaluronic acid is most suitable for oily and combination skin types as it hydrates the skin’s surface when applied topically. Sodium hyaluronate is a derivative of hyaluronic acid whereby the sodium (a.k.a. salt) content is extracted from pure hyaluronic acid. The salt form of this ingredient is more stable and less likely to oxidize. Smaller in particle size than hydrolyzed hyaluronic acid, sodium hyaluronate penetrates deep into skin more easily. It’s perhaps the most common form of hyaluronic acid found in skin care products. Sodium acetylated hyaluronate, known as super hyaluronic acid, is best suited for people who have dry and severely dehydrated skin in need of intense and long-lasting moisture. With higher moisture-binding abilities, super hyaluronic acid is an especially popular form of hyaluronic acid for anti-aging skin care.


What are the benefits of hyaluronic acid?

Capable of holding 1,000 times its weight in water, hyaluronic acid is in high demand in the world of skin care. It acts like a magnet, drawing moisture from wherever possible to hydrate skin. This gel-like substance leaves skin robustly moisturized, plump and soft. For those concerned with skin aging, hyaluronic acid can reduce the appearance of fine lines and wrinkles. Those with dry and dehydrated skin would reap the most benefits from using this ingredient as it’s capable of boosting moisture levels. Hyaluronic acid also speeds up wound repair and healing.


What skin types are most suitable for hyaluronic acid?

Some people may hesitate to use anything with the word “acid” in it, but hyaluronic acid is one of the safest skin care ingredients. It works well for all skin types, even sensitive skin. As this humectant is known for its hydrating and moisturizing properties, it’s most suited for those with dry and dehydrated skin.


What does different molecular weight hyaluronic acid mean?

Not all hyaluronic acids are created equal. The low-molecular-weight form of hyaluronic acid penetrates deep into skin to reach the epidermis, but it binds less water. High-molecular-weight hyaluronic acid binds more water, but it can only hydrate the surface of skin. Those with extremely dry skin should look for the low-molecular-weight variety to deeply hydrate skin.


What should I look for when shopping for hyaluronic acid skin care products?

Before buying a hyaluronic acid product, it’s good to understand what you’re getting. Most hyaluronic acid products are not pure, as they’re engineered to come in smaller-sized particles that effectively penetrate into skin. Hyaluronic acid makes up about one to two percent of the formula because anything more will have drying effects on skin. The remainder of the content is most likely water. For optimal results, look for hyaluronic acid products that come in a variety of molecular sizes, though not all products will indicate the molecular weight of hyaluronic acid used.


How do you use hyaluronic acid?

In your skin care routine, hyaluronic acid can be applied both morning and night right after cleansing and applying toner. This is the best time to apply hyaluronic acid, because your skin is moist, making it easier for hyaluronic acid particles to draw in and preserve moisture. Hyaluronic acid is commonly used in serums; two to three drops of hyaluronic acid serum would suffice. Follow with a facial oil or moisturizer to seal in the moisture.


Hyaluronic acid normally doesn’t react negatively when combined with other skin care products. Its lightweight and watery consistency feels refreshing on skin when applied on its own or with other products. Hyaluronic acid works well when combined with an antioxidant-rich Vitamin C product in the morning skin care routine, like NEOGEN’s Dermalogy Real Vita C Serum. It also pairs well with glycolic acid in the evening skin care routine, like COSRX’s AHA 7 Whitehead Power Liquid which helps revitalize skin and boosts collagen production.


Are there side effects when using hyaluronic acid?

Hyaluronic acid is not known to have adverse effects on skin when used correctly. However, make sure to only use products formulated with not more than two percent of this ingredient. Applying too much hyaluronic acid can have the counter effect of drying out skin. Hyaluronic acid works by drawing moisture from wherever it can. If too much hyaluronic acid is applied, or if it is applied to dry skin in a dry climate, it will draw moisture from the deeper layers of skin.


What are popular hyaluronic acid brands and products?

Hyaluronic acid can be offered as a standalone ingredient, but it’s most commonly infused with other ingredients to provide various skin benefits. Choosing a product containing this humectant depends on what your skin needs.


Elizavecca’s Milky Piggy Hyaluronic Acid Pure 100 and Cos De BAHA’s HS Hyaluronic Acid Serum are popular for being simple formulations consisting of only sodium hyaluronate and water. For those who need something strong to remedy dry skin, MIZON’s Hyaluronic Acid 100 is a great option as it contains ceramide to strengthen skin’s moisture barrier.


For those who want to brighten a dull complexion while hydrating skin, consider iUNIK’s gel-type Vitamin Hyaluronic Acid Vitalizing Toner, which combines niacinamide and hyaluronic acid to deliver hydrating and brightening benefits. For those dealing with sensitive skin, try Dear, Klairs’s Rich Moist Soothing Serum, a vegan-friendly formula that moisturizes skin while delivering skin-calming effects. After using toner and serum in your skin care routine, lock in all the goodness with a facial moisturizer, like COSRX’s Hyaluronic Acid Intensive Cream.
