Multi-depth hydration with three molecular weights.

This formulation pairs the clinically-effective dose with a fragrance-free, low-irritation base. The result is a serum that earns its place in a routine — visible difference in 4-6 weeks of consistent nightly use.

  • Visible difference — most users report change between week 3 and 6.
  • Plays well with others — layer under moisturizer; do not mix with copper or strong acids.
  • Tested — independent dermatological assessment, 28-day in-vivo panel.

I bought one and immediately ordered another bottle. Visible difference at three weeks.

Best niacinamide I've tried

I've used four other niacinamide serums. This is the only one that actually balanced my oiliness without drying me out.

Gentle but slow

It worked, just took its time. No irritation at all which is rare for me with active serums.
