Worst cosmetics

This is COSRX The Vitamin C 23 Serum, a cosmetic product with wrinkle improvement and whitening capabilities.

There is a common perception that Vitamin C serums are irritating, but I was intrigued to try the COSRX Vitamin C Serum because it claims to minimize irritation despite containing a high concentration of 23% pure Vitamin C.

But maybe because my skin is sensitive, even though I try to use it every day to get used to it, it stings as soon as I apply it and is very irritating, so it is hard to use.

It is a very disappointing cosmetic product.
