It's not as appalling as it sounds. According to new research from the Harvard Medical School, an ancient form of aquatic bacteria called Cyanobacteria could be the "it" ingredient to look for in your sunscreen. Turns out, cyanobacteria is just another name for a type of blue-green algae. Now we're heading out of unknown waters, as I have seen this ingredient in some skin care products like under eye creams and antiaging products because of its antioxidant and nutrient values (chlorophyll, B vitaimins, beta-cerotene, vitamin A, lipids, and fatty acids). And I just came across this entire line of blue-green algae products from Aubrey, which includes a toner, moisturizer, and mask. Here's why it may work in sunscreen, too: Blue-green algae are photosynthetic, meaning they get their energy from sunlight (we can all relate to that, right?). But not all sunlight is good for the blue-green algae (we should relate to this, as well). Over time, the algae began to filter out harmful rays and started to protect themselves from UVA and UVB rays by producing mycosporine-like amino acids, small molecules that protect freshwater organisms from solar radiation. The Harvard researchers say these molecules function much like ingredients used in sunscreen today. Convinced? Time to slather up ... with bacteria!
