Ectoin

Product Description

Ectoin is a natural amino acid derivative originally discovered in extremophilic microorganisms that thrive in harsh environments such as salt lakes and deserts. Classified as an “extremolyte,” it acts as a strong cell protectant by stabilizing proteins, cell membranes, and DNA structures through the formation of protective hydration shells. In cosmetic applications, Ectoin is valued for its powerful moisturizing, soothing, and anti-aging properties. It effectively reduces oxidative stress, protects against UV-induced damage, pollution, and dehydration, while reinforcing the skin barrier. Ectoin helps to calm irritation, reduce redness, and restore skin resilience, making it particularly suitable for sensitive and dry skin. Widely used in serums, creams, and repair lotions at concentrations of 0.2–2%, it is highly compatible with other active ingredients such as hyaluronic acid, glycerin, and retinoids, delivering synergistic hydration and protection benefits.
