Algae contain three major classes of photosynthetic pigments categorized as chlorophylls, carotenoids (carotenes and xanthophylls), and phycobilins [139]. The chlorophylls and carotenes are fat‐soluble molecules and can be readily extracted by using organic solvents (acetone, methanol, or DMSO). However, the phycobilins being water‐soluble can be extracted by using polar and nonpolar solvent mixtures. Most of these pigments can counteract against the UV light exposure during growth and development of algae and are known to involve in protecting the cell against harmful oxidative ROS species [140, 141]. Hence, these pigments are used in cosmetic formulations not only to reduce the oxidation of oils, occurring due to rancidity, but also to reduce skin aging, owing due to antioxidant nature. Moreover, these pigments are a natural source of dyes and colorants, making it useful in the various cosmetic industry as the replacement against synthetic dyes (Table 4.2). The various pigments and their cosmeceutical application with respect to antiaging and skin lightening are discussed as follows.
