Efficacy score of 4.4 reflects excellent SPF50+ PA++++ filter blend (Titanium Dioxide + photostable chemicals like Tinosorb S/M and Uvinul A Plus covering full UVA/UVB), plus synergistic niacinamide (high position ~5-10%) and glutathione (1000ppm per ) for tone-up, but deducts for late-list actives like ascorbic acid/arbutin (positions 40+ likely <0.1%, minimal impact) and potential instability of pure Vitamin C in sunscreen pH/formula.
