Ectoin protects bacteria living in literal volcanic salt lakes. Now imagine what it does for your skin.⁠ ⁠ This ingredient was discovered in extremophile bacteria that survive conditions that would kill almost everything else — extreme heat, UV radiation, high salinity. They produce ectoin to protect their cell membranes.⁠ ⁠ When scientists applied it to human skin cells? Same protective mechanism activated. If it shields bacteria from volcanic stress, it can shield your skin from UV, pollution, and oxidative damage.⁠ ⁠ Science is wild.⁠ ⁠ #dermatologist #ectoin #skincarescience
