Ingredients

Apply after toner, then follow with moisturizer and daytime sunscreen.

This formula centers on 3-O-ethyl ascorbic acid, a stabilized vitamin C derivative used to help brighten dull skin and reduce the look of uneven pigmentation. Vitamin C derivatives are popular because they offer antioxidant support while helping skin look more radiant and even over time. Niacinamide complements that role well by helping improve visible discoloration, supporting barrier function, and contributing to a smoother, more refined appearance. Those two ingredients are often paired in tone-correcting serums for exactly that reason.

The formula also highlights additional antioxidant vitamins and a lightweight texture, which makes it more suitable for regular use on skin that may not tolerate heavy or greasy serums. That matters because consistent use is what usually drives visible tone improvement. In practical terms, this serum is best understood as a daily brightening treatment that targets lack of radiance, uneven tone, and early firmness concerns while keeping the finish comfortable for sensitive or easily overloaded skin.
