Reliable Niacinamide Serum

A solid serum that delivers what it promises. My skin is less oily, and breakouts heal faster. The bottle is small, but the formula is concentrated, so a little goes a long way.

Acne Marks Fading Away

This serum has helped lighten my stubborn acne scars. I like how it doesn't irritate my sensitive skin, even at 15%. It's quickly becoming one of my favorite spot treatments.

Strong Concentration, Visible Results

I can tell this serum is high-strength because my skin looked smoother and brighter after just a couple of weeks. I use it carefully to avoid over-exfoliation. It's powerful, but effective.
