Colorimetric analysis of popular tinted sunscreens and practical implications
摘要
Tinted sunscreens are recommended for individuals with skin of color (SOC) to protect against visible light (VL) and ultraviolet A (UVA)-1, which can exacerbate pigmentary disorders. However, most are marketed as a single universal shade, which may not suit the full range of skin tones and can limit adherence. This study objectively evaluated 20 top-selling universal tinted sunscreens using colorimetric analysis. Most products clustered around shades corresponding to Fitzpatrick skin types III-IV, with few suitable options for the lightest or darkest skin tones. Poor shade matching may prompt consumers to apply less product or remove excess to improve appearance, likely compromising UV protection. Objective colorimetric analysis offers a reliable way to evaluate shade inclusivity and guide formulation improvements. Expanding shade ranges and optimizing pigment composition could improve accessibility and adherence, particularly in SOC populations.
