Blue-green algae may become sunscreen’s latest “it” ingredient, according to research from Harvard Medical School. In addition to impressive antioxidant and nutrient values (chlorophyll, B vitamins, beta-carotene, and fatty acids), this algae also shows UV-fighting potential.
Here’s the theory: Blue-green algae is photosynthetic, meaning it gets energy from sunlight. But because not all of the sun’s rays benefit blue-green algae, it filters out harmful rays, producing small molecules that shield it from solar radiation, much like UV-protective ingredients used in sunscreen today. Before algae-based sunscreens hit the stores, you’ll find it in moisturizers combined with other anti-UV ingredients.
