Photoprotection With Mineral-Based Sunscreens

BACKGROUND: Although chemical sunscreens have traditionally been at the forefront of sun protection, safety concerns and increasing awareness of the environmental impact of personal-care products have led to greater interest in the use of mineral blockers as photoprotective agents. OBJECTIVE: To examine the safety and efficacy of mineral-based sunscreens to allow patients to make informed choices about ultraviolet (UV) protection. MATERIALS AND METHODS: A review of the literature was performed using the PubMed database. RESULTS: This article provides an overview of physical blockers and focuses on the efficacy of mineral sunscreens in offering broad-spectrum UV protection and safety concerns, including the controversy surrounding the use of nanoparticles. Practical tips for application are also reviewed. CONCLUSION: Mineral sunscreens are an attractive, efficacious option for consumers who prefer alternative choices in sun protection.
