I love CosRX and will

[This review was collected as part of a promotion.] I love CosRX and will continue to have most, if not all, of my skin products by them, however this one didn't really do anything for me. That doesn't necessarily mean the serum is bad, it could just be my skin type. I was trying something new by using it

The greatest so far

My favorite vitamin c so far, the vitamin e gives you the great hydration and you start to notice the glow within two weeks. I keep mine in the fridge after opening so it would not oxidize

Keep Looking Youthful

[This review was collected as part of a promotion.] I have an assortment of professionals who I see for my aging, sensitive skin and they ALL recommend vitamin C. As a result, I use this as often as possible. I mix it with my morning Niacinamide, peptides, and moisturizing sunscreen. I has a slight coppery tint so make sure to pat it on uniformly. People take me for forty something instead of my actual age (61). No lie. Stay out of the sun and use vitamin C.

Vitamina C

[This review was collected as part of a promotion.] Vitamin C is my favorite product. I love the texture. It absorbs quickly, evens out my skin tone, helps with fine lines, and leaves my skin radiant.
