[DERMA FACTORY] Niacinamide 20% Serum 80ml

I was a little worried because of the high concentration, but it actually feels quite lightweight and easy to use. I like applying it regularly whenever my skin looks dull, and the generous amount is definitely a plus. I’ll keep using it!

This high-concentration serum has been incredible for refining my skin! My pores look smaller and my texture is noticeably smoother. It’s definitely a powerhouse for managing oil and promoting an even tone.
