Scientists find a natural sunscreen hidden in hot springs bacteria

Researchers studying cyanobacteria from hot springs in Thailand have discovered a new natural UV-blocking compound with impressive antioxidant power. Unlike conventional sunscreens, it’s biocompatible and potentially safer for both people and the environment. The molecule is produced only under UV and salt stress and uses a unique biosynthetic pathway never seen before. This could help drive a new generation of eco-friendly sunscreens and skincare products.
