Ectoin Is the Little-Known Skincare Ingredient that’s About to Be Everywhere

According to double-board-certified dermatologist, Brendan Camp, MD, “Ectoin is an organic compound found within bacteria that acts as an osmolyte, meaning that it helps cells maintain an appropriate fluid balance.” Translation? It acts as a moisturizer and emollient, hydrating and softening the skin. 

Don’t be fooled, though. Ectoin offers many more benefits than just smoother, more moisturized skin. Take it from board-certified dermatologist, Geeta Yadav, MD. “Emollients work by helping skin retain moisture, but ectoin also offers protective and anti-inflammatory properties as well as skin-brightening benefits. A recent study of the ingredient in children and adults with inflammatory skin conditions showed that ectoin positively influences change in skin dryness, is safe and well tolerated, and can support the health and repair of the skin barrier. Another study shows that it activates antioxidant pathways while inhibiting tyrosinase, the enzyme responsible for skin cell pigmentation.”
