Sunscreens: Updates on Sunscreen Filters and Formulations

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.
