Green beauty unveiled: Exploring the potential of microalgae for skin whitening, photoprotection and anti-aging applications in cosmetics

Microalgae are gaining considerable attention in the field of cosmeceuticals due to their unique profile. In particular, the diverse range of valuable bioactive compounds isolated from microalgae are known to exhibit multiple properties, including anti-aging, antioxidant, whitening, moisturising, and photoprotection, which have contributed to their distinctive profile. In recent years, there has been an increasing effort around exploration of novel natural biologically active substances from microalgae. This trend is in part driven by the global progression towards a ‘greener’ lifestyle. Since compounds derived from microalgae can offer skin benefits without inducing any adverse effects on human health, they are recognised as promising ingredients for innovative cosmetics and cosmeceutical applications. This review paper provides an overview of the changing balance of reliance on traditional topical agents and the prominent role of microalgae as an alternative source for whitening, photo-protection and anti-aging cosmetic applications.
