COSRX Niacinamide 5% + Mucine d'escargot 74% Double Essence, Sérum visage anti-taches et anti-âge, hydratant, éclaircissant, 2,70 fl.oz/80ml

I like the way the product feels and it’s great for my skin. I had to order another to send to my sister. 💋

I like this serum very much，especially in winter time. It can keep my skin more hydrated and avoid dry. Recommend it!

It doesn't have a strong scent and has contributed to my skin looking healthier, more even, and visibly brighter.

Not gonna ramble just wanna say buy this product and purchase the cream too! Don't use this product on dry skin and sit back and watch your skin transform! It's an amazing product for mature skin.

Menopause make your skin feel dry even your face… I’ve bought it about two weeks ago and I feel and can see a difference in my skin. It’s not a huge drastic change but there is change for the better! I will continue to buy it.

If you have dry skin and need help in the winter...buy this. It leaves my skin so plump, hydrated & happy! A little goes a long way and it absolutely helps with my skin's quality texture, and ability to retain moisture over time.

My face has never felt so smooth and non flakey. I have used many moisturizers and they just rub off later. The sides of my nose and eyebrows suffer from flakeyness for years nothing worked until this product. When it is gone I will definitely buy more!

Despite the ewww when you read 'snail' the way my skin feels after using this product means I will keep coming back. First purchased in Korea, it's since become a staple in my beauty routine. Luv it!
