Vitamin C serum

COSRX Vitamin C Serum

First of all, the price is incredibly cheap, and it applies well.

Because it contains as much as 23% Vitamin C

It is effective in reducing melanin pigmentation and blemishes.

However, the vitamin content is so high that it can be irritating to the skin.

So it is best to test a very small amount before applying it.

It is best to start by using a very small amount and gradually increase the amount you apply.

I recommend this to those looking for a serum that improves blemishes, as it contains Vitamin C and has moisturizing properties.
