Niacinamide, Salicylic Acid 0.5%, and Glycolic Acid 7%

Niacinamide works at the junction between melanocytes and keratinocytes, intercepting melanin transfer before pigment reaches the visible surface. It simultaneously boosts ceramide synthesis to strengthen the lipid barrier, which is why consistent use addresses both discoloration and dehydration. In this toner, Niacinamide targets dehydration, delivering smooths rough texture for a refined, even surface with consistent use.

Niacinamide
intercepts melanin transfer to fade spots and refine pore texture from within
Salicylic Acid 0.5%
dissolves pore-clogging debris from inside out, unlike surface-level exfoliants
Glycolic Acid 7%
dissolves the bonds between dead cells for faster turnover and brighter surface texture
