Sunscreens: Updates on Sunscreen Filters and Formulations

Photodermatol Photoimmunol Photomed. 2025 May;41(3):e70026. doi: 10.1111/phpp.70026.

Abstract

Background/purpose: Sunscreens are a critical component of photoprotection, shielding the skin from the harmful effects of solar radiation. However, current sunscreens have limitations, including insufficient filters with long-wavelength ultraviolet A (UVA) and visible light (VL) coverage. This review briefly discusses the mechanisms of sunscreen filters, newly developed filters that improve broad-spectrum protection, and examines recent advances in sunscreen formulations that enhance efficacy.

Methods: A targeted literature review was conducted using databases such as Pubmed to identify recent studies published on advancements in sunscreen filters.

Results: Recent developments include novel filters with extended UVA and VL coverage. Additives such as antioxidants and anti-inflammatory agents are also being integrated to bolster skin protection.

Conclusion: Although traditional sunscreens have limitations, ongoing innovations in filter development and formulation science are progressively addressing existing gaps in photoprotection.

Keywords: BEMT; UV; photoprotection; sunscreen.
