niacinamide, tranexamic acid, and UV filters

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 sunscreen, Niacinamide targets dark spots, delivering visibly brightens skin tone and fades uneven patches with consistent use.

Ingredients

Niacinamide, tranexamic acid, and mixed UV filters in a moisture-rich tone-up base.

This formula combines two core sunscreen goals: strong daily UV protection and visible tone support. A blend of organic and inorganic UV filters helps reduce exposure to UVA and UVB, the wavelengths most associated with discoloration, rough texture, and premature visible aging. The treatment side of the formula comes from 5% niacinamide and 2% tranexamic acid, two ingredients commonly used in brightening-focused skincare. Niacinamide helps support barrier function and improve the look of uneven tone, while tranexamic acid is often chosen to help skin appear calmer and more uniform. The moisture-rich base also matters: when a sunscreen spreads evenly and feels comfortable, users are more likely to apply the full amount and reapply through the day. That makes the formula commercially useful as both a protective step and a cosmetic finishing step. That balance between protection, comfort, and even wear is what makes the formula more useful in real daily routines.
