Biomass of Phototrophic Microorganisms As a Source of Active Components for Cosmetics

The biomass of phototrophic microorganisms (cyanobacteria and microalgae) is widely used in the food, feed, and pharmaceutical industries. Extracts from the biomass of microalgae and cyanobacteria, as well as various groups of compounds (lipids, peptides, polysaccharides, pigments, etc.) have a wide range of biological activity, which makes microalgae and cyanobacteria a very promising source of a wide variety of new bioactive molecules for inclusion in cosmetic formulations to combat the signs of aging, in sunscreens, bleaching agents, wound-healing preparations, etc. This review focuses on the use of phototrophic microorganisms in cosmetic products based on their biological activity.
