TIA'M - My Signature C Source 30ml

This vitamin C is diluted in a water base so its tends to oxide easily if you don't keep it in your refrigerator. So leaving aside the disadvantage of its rapid oxidation, in general I liked the product. It has a sticky texture that can not please many people and, it really has a citrus scent but I can perceive a subtle aroma of alcohol that is the third ingredient. The concentration of vitamin C, which in this case is ascorbic acid, is 20% so if you're first time using acids you have to include it slowly in the facial routine, but always remember to do the patch test to rule out any reaction. In my case, despite I'm having been using acids for more than two years, the skin always turns red, so I do not use it daily in the first two weeks, until my skin feels comfortable to use it daily. It is also important that after 15-20 minutes (the time you need for the serum to be absorbed by the skin) the other products that you apply on the skin must be moisturizing.
I've noticed some improvements on my skin like the reduction of my cystic pimples during my period, also my skin looks brighter and I feel it smoother. Besides the wrinkle around my mouth (nasolabial fold) is less deep and I really happy with this result. I use it in the morning because the vitamin c is antioxidant that helps us to keep the skin protected from the UV.

This serum has cleared my skin tone and in a short time it has become one of my favorite sera. I love it, I love this product because it is absorbed in my skin and gives it an immediate shine. A recommendation so that it does not rust early, please after opening and use it to store it in the refrigerator. I would buy it again without hesitation.

This vitamin c serum is sticky and has a citrusy scent. It didn't do much for my skin though.

i really enjoy this serum! there have been visible effects after some time of using it and my complexion overall is evener. it does leave ​a sticky feeling but i don't mind that at all

Along with missha fte and instree hyaluronic toner makes my fine lines disappear. Brightens and fades the hyperpigmentation. I apply it after low ph cleanser and leave it about 15 20 min before continuing with my routine.

This is the best skin skin care product that I hv ever used. Just love it. Gives glowy and clear skin.

I love tiam c source, after using it my skin start glowing. Acne spots almost finished. I can see visible difference in my skin it's getting brighter. My occasional acne is finished. I ll never stop using this product. I just love love this product. Best skincare product of my life.
After using it I hv recommended this to many other people and they all like it. Highly recommended ❤️❤️

this is my second bottle. i really love this serum. i higly recommend this product.

My order arrived today and I am so excited as a new yesstyle shopper. This is the first product I tried. I've only used it once so far but love how quickly it absorbs into my skin and gave it an immidiate glow.

I only got into skincare routine after discovering YesStyle.com. So to start my routine I selected this Vitamin C serum because the price was very reasonable and I didn’t want to invest a lot into a new product. Also the reviews all over the Internet were very positive. I have been using it for almost 3 weeks now and I can say that so far so good. It hasn’t done miracles and one shouldn’t expect miracles either. One should give some time for a product to work. However this product is gentle on my skin and I feel that my skin has started to look healthier. I think it is a good serum to start with, even though it has high % of Vitamin C, so may be people with sensitive skin should be cautious. I am hoping to see significant/noticeable difference after using it for some time. Perhaps I will update about my skin condion in a couple of months time.

This vitamin c serum really helps to lighten my hyperpigmentation. I have combination skin that is prone to breakouts, but you wouldn’t be able tell because this has really helped to get rid of any scarring.

Very good product, easy to use. I hightly recommand it . I will purchase it again.
