Brief
Summary
The article "UV Filters: Challenges and Prospects" reviews the current issues with UV filters used in sunscreens, specifically their photostability and potential toxicity to both humans and the marine environment. It discusses how some UV filters can degrade into toxic by-products and negatively impact marine organisms like corals, mussels, and fish. The article then explores the prospects for developing next-generation UV filters that are safer and more stable, highlighting research into natural compounds from botanical and marine sources (like mycosporine-like amino acids (MAAs)) and the synthesis of new organic derivatives. It also touches upon strategies to improve the photostability of existing filters, such as encapsulation and the use of antioxidants. Ultimately, the article emphasizes the ongoing need for innovative, safe, and effective UV filters.
