The Moisturizing Sheet Mask Formulation of Black Soybean (Glycine soja) Ethanolic Extract

Abstract

     The purpose of this sudy was to find out the mask sheet by using black soybean extract as a moisturizer and to know its ability to increase water content or moisture on the skin. Sheet masks were formulated with the addition of black soybean seed extract with a concentration of 1%, 3%, and 5%, then an evaluation of the formula was carried out in the form of homogeneity, pH, skin irritation test, stability, and the activity test to moisturize whites. The results of the evaluation of the formula showed that the sheet mask was homogeneous, pH value 6.1-6.8, did not irritate the skin, and was stable in storage for 4 weeks. The highest percentage increase in humidity occurred in the group using positive control followed by the Black Soybean Sheet Mask (BSSM) 5%. There is a significant difference between the positive control group, BSSM 3 and 5% against negative control, except BSSM 1%. In the second to fourth week, the 5% BSSM group showed an increase in numbers so that it did not differ significantly from positive control, so this was marked as the optimum concentration. The conclusion of this research is that black soybean seed extract can be formulated in sheet mask form and can increase skin moisture.
