New to the brand and purchased this one after reading reviews and doing independent research and so glad I purchased. So far if glides across your skin, it is moist and makes my skin feel soft, hydrated and dewy. Not sticky tacky or heavy. Easy to use no need to weigh down tour face with plenty if product a little goes a long way. Really happy so far!!!


I like the peptide content and ingredients and this brand is well known.
Give it a try!

I like this serum.
I use it right after I wash my face and apply it with my hands.
As soon as it dries it appears to soften my face, lines for a bit. It dries quickly and you do not feel dry or stickiness


I've been using this product for a couple of weeks and I am really enjoying it so far. It is very hydrating, due to the hyaluronic acid, NAG, and peptides in the formula, and as a result, is very nicely plumping for fine lines and wrinkles. I don't have any wrinkles yet, but I did notice a reduction in the prominence of my smile lines.

I certainly recommend this product for people with red, sensitive skin. I use a prescription acne product overnight that dries my skin out, so when I wake up the next day and use this product (as well as numerous other COSRX products) my skin feels hydrated and revitalized! I've even just put this on my face in the mornings when I'm feeling lazy and it's done the trick. It gives you a glass skin glow without being oily, and dries down completely without feeling tacky or sticky on the skin. Your skin really just drinks it up. At least mine does! I feel this product is high quality without being overpriced, which is amazing. Overall this serum is really easy to use and easy to spread across the face an neck. 10/10, really do recommend!
