Over the years, bioactive and biocompatible natural products have received increased attention as ingredients of cosmeceutical formulations owing to their robust properties compared to many of the synthetic chemicals in use. Many natural products derived from algae have shown promising cosmetizing properties. Seaweed polysaccharides, in particular, have received increased attention for their biofunctional and physicochemical characteristics. This study aimed to design a cost-effective strategy to purify fucoidans from the untapped brown algae Chnoospora minima (CMF) and Sargassum polycystum (SPF) harvested in Sri Lanka and to evaluate their cosmetizing properties. Based on Fourier transform infrared (FTIR) spectroscopy and monosaccharide composition analysis, the purified polysaccharides were rich in fucoidan. Relatively high sulfate content was detected in both fucoidans. Experiments were carried out to evaluate antioxidant, UV-protective, anti-inflammatory, antiwrinkling, and skin-whitening effects. Both CMF and SPF showed 2,2-diphenyl-1-picrylhydrazyl (DPPH) and alkyl radical-scavenging activities, anti-inflammatory effects on lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages, considerable collagenase and elastase inhibitory properties and skin-whitening effects via direct inhibition of tyrosinase, and intracellular melanin synthesis indicating promising cosmetizing effects.
