Ectoine is a cyclic amino acid produced by extremophilic bacteria. These extremolytes survive under extreme conditions such as severe dryness, UV radiation or high salt concentrations. Ectoine is produced via fermentation by a bacterium.
Ectoin has a cell-protecting and anti-inflammatory effect by forming a protective shield of water molecules around itself and around neighboring proteins and cell membranes. This Ectoin hydro complex means it is used in cosmetic care to protect the skin from damage caused by stress factors such as UV radiation, dryness, fine dust or allergens. The moisturizing effect of Ectoin is long-lasting. It is very suitable for all skin types - including for preventing the formation of wrinkles.
In medical products, Ectoin is used for irritations or inflammatory diseases of the skin or mucous membranes.
