READ MORE

Efficacy score docked to 3.9 due to Avobenzone's rapid 36% degradation in sunlight without sufficient stabilizers like Tinosorb, Octocrylene only partially helps but requires reapplication; Ascorbyl Glucoside is stable but converts poorly to pure Vitamin C (needs ~10-15% for efficacy, likely lower here mid-list) missing Ferulic synergy; peptides and niacinamide add value but no encapsulation or optimal pH confirmation for actives; water-based gel packaging preserves stability better than jars.[1][2]
