Evidence review and product analysis highlight gaps in visible light protection and labeling for skin of color
This is a must-read article in the current issue of JDD that reviews clinical data on iron oxide for hyperpigmentation and audits commercial tinted sunscreens for disclosure of iron oxide content. The authors performed a literature review of studies assessing iron oxide for visible light induced pigmentation and analyzed 37 marketed tinted sunscreens, including direct contact with manufacturers.
The clinical literature summarized supports that iron oxide-containing sunscreens can improve outcomes for visible light-triggered hyperpigmentation. The product analysis found that most tinted sunscreens do not list iron oxide as an active ingredient, only a small fraction of brands disclosed iron oxide concentrations when queried, and few manufacturers provided transparent testing data for visible light protection.
For dermatologists and dermatology HCPs, the report raises practical considerations about product selection for patients with hyperpigmentation and skin of color and underscores a need for standardized labeling or testing metrics for visible light protection. The findings also point to opportunities for better patient education and for clinicians to ask specific questions about product formulation when counseling on photoprotection.
Read the full JDD article for the literature synthesis, product list, and the authors’ recommendations on disclosure and testing standards to guide evidence-based photoprotection in patients prone to hyperpigmentation.
