It’s neither a ‘fancy-word’ nor ‘new-word’ to the cosmetics world but the applications of microalgal ingredients for making cosmetic products is in its infancy. Cosmetics products may include creams, lotions, powders, perfumes, lipsticks, shampoos etc. that may be used for cleansing, beautifying, promoting attractiveness, or altering the appearance of human beings without affecting the body's structure or any functions.  Cosmetics products usually consist of synthetic chemicals including colours and flavours but the trend has now changed with increasing applications of biological ingredients. Microalgae stand above from natural biological ingredient point of view because  microalgae has a range of molecules with varied bioactive properties/principles are colours (chlorophyll, carotenoid, and phycobili pigments), essential oils (omega 3 and 6 fatty acids), antioxidants (astaxanthin, lutein, β-carotene, ergothioneine, ascorbate, glutathione, superoxide dismutase) and UV-screening compounds (mycosporine-like amino acids, scytonemin),  minerals and essential amino acids. These bioactive molecules can suitably and sustainably obtain from microalgae for incorporation in cosmetics products for human benefits.
