Ectoin is a natural cell protection factor discovered in halophilic bacteria, such as Ectothiorhodospira halochloris, which persist and propagate under extreme conditions in saltwater, the sea, and saline deserts. These halophilic bacteria are exposed to high UV irradiation, extreme temperatures, and high salinity.
Nevertheless, they adapt to these inhospitable conditions: their survival is guaranteed by a unique amino acid, namely Ectoin. The bacterial biopolymers are stabilized by producing Ectoin and protected against these damaging external stressors.
Ectoin improves the skin's water-retention capacity, has a hydrating and anti-inflammatory action, and stabilizes cellular structures by its protective effect on cell membranes. In addition, it enhances cell protection against damaging environmental factors and conditions, such as extreme temperatures, high salt concentrations, low humidity, and UV exposure.
Ectoin is also one of the best natural options available to stimulate skin cells' protective properties, like cell and immune system maintenance, and offers UVA protection. In addition, based on an in-vivo study, it can improve the tactile properties of skincare products.
