Ectoine

Ectoine is a natural compound which serves as a protective substance in many bacterial cells. Ectoine is found in high concentrations in halophilic microorganisms and confers resistance towards salt and temperature stress. Ectoine was first identified in the microorganism Ectothiorhodospira halochloris, but has since been found in a wide range of gram-negative and gram-positive bacteria.

Use
Ectoine is used as an active ingredient in skin care and sun protection products. It stabilizes proteins and other cellular structures and protects the skin from stresses like UV irradiation and dryness.
