Sunscreen formulations derived from natural sources are gaining attention due to their eco-friendly properties and potential health benefits. Algae, a diverse group of aquatic organisms, have emerged as a promising source of bioactive compounds with UV-protective capabilities. Their rich composition of mycosporine-like amino acids (MAAs), carotenoids, and polyphenols provides effective shielding against harmful ultraviolet radiation, making them valuable candidates for natural sunscreen development.  

This study explores the formulation of sunscreen using algae-based extracts, focusing on their photoprotective properties, stability, and biocompatibility. Marine and freshwater algae, such as Spirulina spp., Chlorella spp., and Dunaliella salina, are known for their antioxidant-rich profiles, which can help mitigate UV-induced skin damage. Beyond their protective functions, algae-based sunscreens offer a sustainable alternative to synthetic UV filters, reducing environmental impact and supporting the development of biodegradable skincare solutions.  

The formulation process involves selecting suitable algae species, optimizing extraction methods, and incorporating bioactive compounds into stable sunscreen formulations. This research aims to enhance the efficacy of algae-derived sunscreens while ensuring skin safety and compatibility, paving the way for innovative, nature-inspired photoprotection.
