Korean Serum

Is serum necessary in a Korean skin care routine?

Serums are popular in many people’s skin care routines as they are formulated with specific active ingredients to tackle a range of skin issues. A serum usually contains a combination of powerhouse ingredients in order to bolster the skin benefits.

Serums are part of the famous ten-step Korean skin care routine. Serum is usually preceded by toner and followed by moisturizer. Depending on your needs, you may choose a different serum for different days of the week to reap the most benefits. You may apply serum only to areas of concern, or layer two or three serums over the entire face.

Due to the high ingredient potency, only a small amount of serum needs to be applied each time, so serums usually come in smaller bottles than toners and essences. The packaging is also determined by product texture and other functions.

How to apply Korean serum

Korean serums usually come in a dropper bottle if the formulation is watery, or pump bottle if the formulation is dense. Use serum one to two times daily in the morning and night. To use, massage a small amount onto cleansed and toned skin. Pat lightly to enhance absorption, and then finish with moisturizer to seal in moisture. Thicker serums require more time to absorb and should be left on skin longer.

The kind of ingredients in a serum formula can affect usage so make sure to read the product’s instructions before use. Some serums, for example, contain retinol which can increase skin’s photosensitivity, so only apply at night and make sure to use sunscreen the next day.

When layering serums, apply the thinnest formula before moving on to thicker ones. Avoid combining active ingredients that don’t mix well or boost skin irritation. For example, if you’re using a retinol serum, then don’t use AHA, BHA or Vitamin C serums at the same time to avoid overwhelming and irritating skin. Instead, layer with a soothing or hydrating serum.

Those with sensitive skin should do a patch test before use to avoid irritation or other skin issues after application.

What are the best Korean serums?

Serums come in high concentration of active ingredients, so it’s crucial to choose the right serum for your skin type. Oily skin, for instance, benefits from serums that regulate sebum production, while dry and dehydrated skin may need thicker or even oil-fused serums to moisturize skin.

Best Korean serum for acne

Those with acne-prone skin should opt for a gentle serum that absorbs into skin easily and doesn’t clog pores. Remember to choose a formula made without potential irritants like fragrances, ethanol and sulphates. Look for soothing ingredients like centella asiatica, green tea extract and tea tree oil. Korean skin care brand SKIN 1004’s Madagascar Centella Asiatica 100 Ampoule is enriched with centella asiatica extract to calm troubled skin. Formulated with EWG green-grade ingredients, the slightly acidic serum is readily absorbed by skin thanks to its watery texture. It’s clinically tested for skin irritation.

Best Korean serum for hyperpigmentation

If you’re dealing with uneven skin tone, dark spots, blemishes, acne scars and dull skin, choose a Korean serum rich in brightening ingredients like niacinamide, tranexamic acid and Vitamin C. Anua’s Niacinamide 10% + TXA 4% Serum is infused with 10% niacinamide and 4% tranexamic acid to fade dark spots and acne scars, while containing hyaluronic acid and botanical oils to hydrate skin.

Best Korean serum for oily skin

Those with oily skin typically deal with skin issues associated with excess sebum production, such as enlarged pores, blackheads, acne and an oily T-zone. To balance oil levels, aim for serums containing ingredients with the ability to absorb or control sebum like charcoal, kaolin, green tea extract and tea tree oil. Exfoliating ingredients like AHA (such as glycolic acid) and BHA (such as salicylic acid) help remove blackheads and refine uneven skin texture. Formulated with antioxidant-rich green tea ingredients, innisfree’s Green Tea Seed Hyaluronic Serum balances skin’s oil levels for healthy and clear skin. Unscented and noncomedogenic, the green tea serum is suitable for all skin types including oily skin.

Best Korean serum for dry skin

Dry skin may indicate a compromised skin barrier. Serums containing emollients like ceramides and fatty acids like stearic acid help replenish skin moisture, seal in moisture and reinforce the skin barrier. Nourishing and antioxidant-rich ingredients like panthenol and Vitamin E also help restore damaged skin back to health. Boasting a lightweight and refreshing texture, Torriden’s DIVE-IN Low Molecule Hyaluronic Acid Serum is perfect for those with dry skin thanks to 5D-Complex Hyaluronic Acid in the formula.

Best Korean serum for uneven skin texture

If you’re dealing with clogged pores, dullness or a buildup of dead skin cells, an exfoliating Korean serum can restore skin smoothness and a healthy glow. AHA, BHA and papain extract are all effective exfoliants to smooth rough skin. COSRX’s The 6 Peptide Skin Booster enhances skin elasticity and refines skin texture while providing pore care. Microneedling is another way to stimulate collagen production for plump skin. VT’s Reedle Shot 100 stars small molecular-sized hyaluronic acid plus macadamia seed oil to amp up skin’s moisture levels for a plump appearance.

Best Korean serum for anti-aging

Anti-aging serums are usually formulated with ingredients such as retinol, snail mucin, peptides and collagen to minimize wrinkles and firm skin. COSRX’s Advanced Snail 96 Mucin Power Essence is enriched with a whopping 96% snail secretion filtrate, which helps to repair aging skin and soften the appearance of fine lines. The moisturizing and healing properties of this K-Beauty favorite make it a great companion to retinol or Vitamin C serums.
