This study was conducted to investigate the antioxidant function and skin safety of Opuntia humifusa (O. humifusa) in order to investigate its potential as a cosmetic ingredient. In addition, radical scavenging experiments using DPPH and ABTS of extracts from O. humifusa with different extraction conditions were performed, and a method of extracting a lot of effective substances was selected, and the antimicrobial activity was also analyzed. As a result, according to the results, the original ingredients of raw material (O. humifusa) and hot water extract contained 83.8% and 97.9% of moisture, and 12.4% and 1.2% of carbohydrates, respectively. Among trace elements, the content of calcium and magnesium in O. humifusa was high, and some water soluble dietary fibers were contained too. Particularly, in the radical scavenging experiment using ABTS, the activity was high 30% when hot water was extracted after enzyme treatment than when ethyl alcohol was extracted after enzyme treatment. The hot water extraction process after enzyme treatment had a great antimicrobial effect for B. subtilis ATCC 663. As a result of evaluating the safety of O. humifusa extract as a raw material through Guinea pig, there was no change in body weight in the control and O. humifusa extract treated groups. There was no rubefaction, red spot and edema in the O. humifusa treated group. Also, preciffitant, pH stability of cosmetics made from O.humifusa extract found out no change. Therefore, the potential as a raw material for functional cosmetics of O. humifusa was confirmed.
