I've been consistent with this and the brightening is slow but real, especially on dark spots. The hydrogel mask feels cooling and leaves my skin looking calm and hydrated after.

I have noticed instant glow up with using this niacinamide. Whether i use it at night or layered in my make up, it just instantly makes a difference. Love COSRX products so much!

The Best Serum for Oily, Acne-Prone Skin!
Reviewed: 3 months ago
Purchased by reviewer
Been using this Niacinamide 15 for months and I can say that this is the best serum for someone with oily, acne-prone skin like me. It has higher niacinamide content which makes it work faster and better on the skin. It prevents acne, oil, and heals dark spots faster. The glass bottle that it comes in is also a good idea for the packaging.

Really Helped My Acne Marks
Reviewed: 10 months ago

Been using the COSRX Niacinamide 15% Serum for a few weeks now and wow, it really helped lighten my dark spots. My acne marks don’t look as strong anymore and my skin looks more even. The serum feels light, not sticky, and it absorbs fast. I was a bit scared at first since it’s 15%, but I just used it slowly and it didn’t irritate my skin. Super happy with the results so far!

I had been searching for a long time for something that could lighten the dark spots on my face. I tried so many serums, but they only damaged my skin barrier. I'm so glad I finally tried this—it's truly worth it!
