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.
