The aim of this study was to analyze the fatty acid content of Skeletonema costatum crude extract by using avocado oil as the solvent and determining its effectiveness as an anti-aging cream. Sonication was used as a method for fatty acids extraction of Skeletonema costatum. Lipid content of Skeletonema costatum was analyzed by GC-MS and FTIR, while skin condition was measured by skin analyzer. The test of cream effectiveness was carried out towards 15 panelists aged 20-60. The highest fatty acid content in lipid of Skeletonema costatum crude extract reached 45.37% with a ratio of concentration `of 1:25 w/V than other result (1:10 w/V, 1:20 w/V, 1:30 w/V, 1:35 w/V and 1:40 w/V). The fatty acid of Skeletonema costatum consists of palmitic acid, palmitoleic acid, linoleic acid, oleic acid and stearic acid. The results of this study showed that fatty acids can increase the skin moisture and improve the structure of the panelist’s skin. This paper provides for the first time using avocado oil as a solvent to extract fatty acids of skeletonema costatum as anti aging-cream.
