Niacinamide, Retinol 1%, Collagen, Allantoin, and Aloe Vera

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 serum, Niacinamide targets dehydration, delivering restores skin's natural bounce and elasticity with consistent use.
