DropBrigt® KAD | Kojic Acid Dipalmitate

DropBright® KAD is a lipophilic derivative of kojic acid known for its exceptional stability and effectiveness in skin-brightening applications. Unlike kojic acid, KAD is more resistant to heat, light, and oxidation, ensuring long-term efficacy in cosmetic formulations. By inhibiting tyrosinase activity, it reduces melanin production, helping to improve skin tone, lighten dark spots, and reduce hyperpigmentation.
