The cosmetic industry uses the term ‘cosmeceutical’ to refer to a cosmetic formula that has drug-like applicative advantages. Many marine algae are rich in biologically active components that have been reported to exhibit strong benefits to the skin, mainly for photoprotection, skin whitening, moisturization, anti-aging, anti-wrinkle, antioxidants, and antimicrobial uses.
For the preparation of cosmeceutical products, macroalgae-derived compounds have been noted as being of significant importance [19]. Polysaccharides have a great role in cosmetics including in moisturizers, emulsifiers, wound healing agents, and thickening agents [20]. Fernando et al. [21] have reported anti-inflammation activity of Fucoidan from Chnoospora minima (Phaeophyceae) by inhibition of Lipopolysaccharides induced nitric oxide production, inducible nitric oxide productions, Cyclooxygenase-2, and Prostaglandin E2 levels in an experimental study by targeting RAW macrophages. Likewise, Ariede et al. [22], Wang et al. [23], and Teas and Irhimeh, [24] reported beneficial activities of Fucus vesiculosus (Figure 1a) (Phaeophyceae) derived polysaccharides such as anti-aging, anti-melanogenic, anti-cancer, and antioxidant activity by stimulating collagen production, tyrosinase inhibition, decreasing melanoma growth and by preventing oxidation formation, respectively. In addition, the anti-inflammation activity of sulphated polysaccharide from Padina tetrastromatica (Phaeophyceae) by COX-2 and iNOS inhibitions in an experimental model of Paw edema in rats [25]. Moreover, Khan et al. [26] reported the anti-inflammation activity of polyunsaturated fatty acids derived from Undaria pinnatifida (Figure 1b) (Phaeophyceae) on mouse ear edema and erythema. In vitro, the antioxidant activity of methanolic extracts from Osmundaria obtusilo and Palisada flagellifera (Rhodophyta) was studied by DPPH, ABTS, metal chelating, Folin ciocalteau, and beta-carotene bleaching assays [27][28]. Phenolic compound Sargachromanol E revealed antiaging activities from Sargassum horneri (Phaeophyceae) by inhibition of matric metalloprotein expression on UVA irradiated dermal fibroblast [29].
Marine macroalgae derived polysaccharides are well known for their biological benefits. The presence of polysaccharides (ulvan, fucoidan, alginate, laminarin, carrageenan, sulphated polysaccharides, agar, and agarose) in macroalgae and noted their cosmeceutical benefits. Other examples of macroalgae derived polysaccharides and their cosmetic benefits are presented in Table 1.
