New scoring system assesses white cast from mineral sunscreens in diverse skin tones, suggesting better compliance.
Key Points
The developed scoring method correlates higher ZnO concentrations with more visible white cast and lower user acceptance.
Statistical analysis revealed a strong correlation (r ≥ 0.822) between ZnO levels and whiteness, indicating significant findings for sunscreen formulation.
Assessment utilized both subjective evaluations and objective CIEL*a*b* metrics to ensure reliability across various skin tones and formulations.
This scoring system may enhance sunscreen compliance by informing manufacturers on cosmetic acceptability for different skin tones.
