development of peel-off mask ethanolic extract sargassum polycystum and its antioxidant activity using dpph (2,2-diphenyl-1-picrylhydrazyl) method

One of the unique characteristics of the peel-off mask is that it will create a layer of translucent, elastic film. after drying, there is no residue and it may be removed without rinsing. the production of masks from natural materials is preferable to that from synthetic materials, which might have negative side effects and alter natural contour of the skin. s. polycystum is one of the natural products that can be used as a mask with natural ingredients. antioxidants included in s. polycystum act as a deterrent to free radicals. s. polycystum contains phenolic compounds, carotenoids, laminarins, alginates, fukoidans, florotanins, and ectoin among other antioxidants. the objective of the study was to find the optimal amount of s. polycystum extract to incorporate into peel-off masks with high antioxidant activity. the sample is prepared using the ultrasonic assisted extraction technique with s. polycystum powder and ethanol as the solvent. a peel-off mask was made utilizing s. polycystum extract in concentrations of 0%, 3%, and 4%. testing the mask’s quality includes an organoleptic test, a ph test, a homogeneity test, a stability test, a drying test, and an antioxidant activity test using dpph with an ic50 concentration. s. polycystum extract can be made into a peel-off mask, according to the research. the formulation of a 4% s. polycystum extract peel-off mask was selected since it met the requirements of a peel-off gel mask of the indonesian national standard (it is homogeneous and stable, ph 5.6, and dry time 17 minutes with an ic50 of 125.20 mg/ml, which is a moderate antioxidant).
