As always with COSRX, great serum and works as advertised. It’s hydrating and brightening for a morning serum on my combo skin. It’s great on my oily spots and has helped with my plaque psoriasis flare ups on my face, especially on my chin and around my eyes. Gentle exfoliation that you can use in the morning.

Very good, serum for brightening the skin and exfoliate dead skin cells

It's actually good, just don't forget to use sunscreen!

I love all the product from Stylekorean. They provide only the authentic products to customers. I can say Stylekorean is the most trustful website for everyone who is interested in Korean cosmetics.

This was too gentle for my skin. Love cosrX and StyleKorean

This didnt do anything for my skin unfortunately. There are better products out there. This was too gentle for my skin.

this is light and easy to use, not too strong on senstive skin.

good product not regret purchasing at all. love it

So far so good but I want to give it a couple of weeks or a month to settle my review on this product
