The Niacinamide 15 Serum 20ml

A high-strength serum featuring 15% niacinamide combined with zinc PCA and acetyl glucosamine to target persistent breakouts, enlarged pores, and uneven texture. This is a potent concentration that works particularly well for managing stubborn oiliness and fading post-acne marks. It’s a hardworking formula that rewards consistency, though the high percentage means it's best to introduce it gradually if you're used to lower concentrations.
