A review of the use of microalgae in the production of cosmetics

Microalgae are a diverse group of photosynthetic eukaryotic and prokaryotic microorganisms in different shapes and sizes that have evolved by being in stressful conditions and have devised mechanisms to maintain their survival. The production of unique biochemical compounds called bioactive compounds is one of these mechanisms. These compounds restore and heal the skin and protect the skin from damage caused by various factors, and in many cases these products are used in the treatment of diseases and cosmetic formulations. Today, cosmetic products derived from microalgae, which are environmentally friendly and safe, replaced the products in the market. In this review article, the potential of many species of microalgae and their derived bioactive molecules in the production of cosmetics is discussed. In addition to that, by presenting the current microalgae products in the global cosmetics market, it highlights the importance of these organisms in the use of microalgae in the production of quality cosmetics, and finally by providing suggestions such as encapsulating pigments to increase resistance and the stability of pigments envisages their greater use in the cosmetic industry in the future.
