Formulation view A Japanese high-efficacy sunscreen using a blend of modern chemical filters for broad-spectrum protection. Light ester carriers ensure a non-greasy finish, supported by hyaluronic acid and collagen for hydration. The system uses non-ionic emulsifiers for stability. Ideal for oily or combination skin seeking a breathable finish. Formulator Note: While modern filters like Bis-ethylhexylhydroxymethoxyphenyl benzotriazole offer high stability, their compatibility with other additives must be verified through long-term accelerated testing.
