COSRX Pure Vitamin C 23% Serum with Vitamin E & Hyaluronic Acid, Brightening & Hydrating Facial Serum for Fine Lines, Uneven Skin Tone & Dull Skin, 20ml

This was recommended to me by a top dermatologist and I was beginning my skin care journey with Vit C with this serum. It’s pretty potent and effective and I can see the difference just in a few days

It's so good for my skin Glow:Very nice Texture:Smooth Quality:Very good

It's overpriced but it's better than any other Vitamin C serum obviously because of the Quantity of C. First time users, first use normal 10% Serum then if it suits you then slowly increase the quantity.

Don’t purchase this from Amazon. They have sent an oxidised product which is Orange/ brownish in colour. Vit C serum should be clear or pale yellow in color. Oxidised serum is harmful for skin. Just when I opened the cap fizz came out and it started producing bubbles. This is very dangerous for skin. Seller doesn’t even allow returns so money went in to trash. Please get it replaced. This product is super expensive and the seller is disappointing.

Really really very affective

So this serum did work wonders on my skin during the first few days of usage. My skin was even toned and bright. However, as I later realised I was allergic to vitamin C, my skin began to burn and flake a bit, and I have since then shifted to Niacinamide and copper peptide. The texture is a bit grainy and oily, making it different from the lighter, more aqueous Vitamin C serums.

Very nice

Definitely works. Does not feel heavy after applying. Initially there was a slight burning sensation in places but that is product efficacy I guess. Best to layer it with same brand products. Go buy.
