<![CDATA[Suruhan leaves (Peperomia pellucida L.) are known to be rich in secondary metabolites including alkaloids, flavonoids, saponins, tannins and triterpenoid compounds that have potential as anti-acne so that they can be applied as active ingredients in gel preparations. The purpose of this study was to determine the best base for the formulation of an anti-acne gel preparation of suruhan leaf extract that was physically stable. The research method includes the extraction of suruhan leaves by maceration using 96% ethanol. The gel formulation was designed with variations of carbopol base, HPMC, and Na CMC with a concentration of 2%. Physical stability tests include organoleptic, homogeneity, pH, dispersion, viscosity and adhesion which were carried out before and after accelerated storage using a climatic chamber. The results of this study showed that the gel preparation of the ethanol extract of suruhan leaves using carbopol and HPMC bases produced a physically stable gel based on the results of organoleptic tests, homogeneity, pH, dispersibility, adhesion and viscosity, before and after accelerated storage.]]>
