In 1985, Professor Galinski discovered in Egypxian desert, under high temperature, dry, strong UV irradiation and high salinity, which opened the self-repair function; it is also found in addition to desert, in saline land, salt lake, seawater, which can give a variety of stories. Ectoine is derived from hyperhalophilus, so it is also called "salt-tolerant bacteria extract". Under extreme conditions of high salt, high temperature, and high UV radiation, ectoine protects halophiles from injury. Studies have shown that Ectoine also has a good repair and protective effect on the skin, and is one of the bioengineering agents used in high-grade cosmetics.
