Ectoine is a cyclic amino acid (1,4,5,6-tetrahydro-2-methyl-4-pyrimidinecarboxylic acid) produced by fermentation of halophilic bacteria (Halomonas elongata).
As an extremolyte, it protects cell membranes and proteins from stress (UV, heat, dehydration, inflammation). Used in premium skincare, respiratory-health and general anti-inflammatory supplement applications.
