Seaweeds are rich-sources of structurally novel and biologically active metabolites, with great potential for cosmeceuticals. Seaweeds metabolites have function in cosmetics as additive, bioactive cosmetics and stabilization. Bioactive seaweeds can be applied for skin whitening, anti wrinkle, ptotoprotectant and anti photoaging. Metabolite diversity of red seaweed is richer than green or brown seaweed. Herein, we are going to deliver our research on exploring the potential of Indonesian red seaweeds as source of bioactive and additive agents for cosmetics. We examined 50 species of red seaweeds collected from Yogyakarta, Bali and East Nusa Tenggara for production of primary metabolite hydrocolloid and secondary metabolite mycrosporine-like amino acid (MAA). Seaweeds were extracted using methanol to obtain MAA and hot water-ethanolic to yield polisaccharide. Analysis were completed by employing UV-VIS spectroscopy and LC-MS for MAA. Type of hydrocolloid was analyzed using FTIR spectroscopy. Results indicated that Indonesian red seaweeds are promising sources of diveristy of MAA for photoprotectant, antiphotoaging and antioxidant. The diversity of phycocolloid showed types of carrageenan, agar and galactan sulfate for thickening and mousterizing for cosmetic application.
