To find out a good candidate of cosmetic source and screened for antimicrobial, antioxidant and whitening activities. In the antioxidant experiment, supercritical Halopteris scoparia extraction (SHE) and hydrothermal Halopteris scoparia extraction (HHE) were slightly different depending on the experimental method (Total polyphenol content measurement, DPPH radical scavenging ability, ABTS radical scavenging ability, and SOD-like activity). In the enzyme experiment (Elastase, Tyrosinase inhibition activity), the supercritical extract was more effective. In supercritical fluid, Halopteris scoparia extracts showed good antimicrobial activity against Propionibacterium acnes, Staphylococcus aureus, Bacillus subtilis and Escherichia coli but hydrothermal extract had no effect about the rest of the strains. Therefore, it can be expected that the supercritical Halopteris scoparia extract with excellent antibacterial activity can be used as a cosmetic material.
