Abstract
Disclosed herein is nanoemulsion prepared by emulsifying main metabolites of ginseng saponin obtained by conversion of glucose, i.e. compound K (20-O-.beta.-D-glucopyranosyl-20(S)-protopanaxadiol), ginsenoside F1 (20-O-.beta.-D-glucopyranosyl-20(S)-protopanaxatriol) and compound Y (20-O-[.alpha.-L-arabinopyranosyl(1.fwdarw.6)-.beta.-D-glucopyranosyl]-20-(S)-protopanaxadiol); and admixture thereof, in fine emulsion or liposome with dermotropic emulsifier by nano-emulsification; and having enhanced skin penetration, so to be effective in promoting proliferation of fibroblast and biosynthesis of collagen.
