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.
