Microalgae is rapidly gaining popularity due to its wide range of applications in various industries. Some of the microalgal species are being considered as food alternatives for human consumption, such as Chlorella, as it is rich in proteins, vitamins, and minerals. Some species, such as Crypthecodinium, Schizochytrium, and Ulkenia, have been used as the source of fatty acids (DHA & EPA) to enhance body function and are widely used as an ingredient for infant formula. Microalgae have also shown potential as the next generation of natural ingredients for cosmetics to improve or protect skin health. Mycosporine-like amino acids(MMAs), extracted from cyanobacteria with strong UV absorption ability, are being investigated by both universities and cosmetic industries as an alternative to current mineral/chemical sunscreen products. Botryococcus has also demonstrated the potential to be the alternative source of squalene, which is widely used in skin lubrication and protection products rather than shark liver. While more and more microalgal species are being discovered, majorities are left untouched. As a microalgae biotech company, Iconthin will continue to explore microalgae species and develop cutting-edge biotechnology to recover high-value microalgae extract for nutraceutical and cosmetic industries in order to improve overall human health and boost healthy and youthful skin.
