Ingredients

Niacinamide intercepts melanin transfer to fade spots and refine pore texture from within, while Adenosine promotes collagen synthesis naturally to reduce wrinkle depth over time, creating a formula that addresses multiple needs at once.

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. At concentrations above 4%, it also regulates sebum output without stripping, making it one of the few actives that benefits every skin type.
