A review of bioactive compounds of cyanobacteria and microalgae as cosmetically useful supplements

Today, the valuable metabolites of microalgae are widely used in the production of many cosmetic products, as the biomass of algae contains pigments, proteins, essential fatty acids, polysaccharides, vitamins and minerals, all of which are present in both natural foods and cosmetics are used. In fact, these secondary metabolites with anti-blemish and anti-microbial, anti-aging, sunscreen and skin whitening effects can repair and heal the skin and protect the skin from UV damage and prevent inflammation. Existing cosmetics can in many cases be replaced with microalgae-derived cosmetics that are environmentally friendly as well as safe. The effects of microalgae and their derivatives have been tested in various nutritional studies around the world. However, there are very few studies on their cosmetic applications, so in this review article we tried to study several species of microalgae, cultivation methods, use of biomass and bioactive molecules derived from microalgae in the production of anti-aging products, sunscreen and skin whitening in the formulation of cosmetic compounds.
