The present invention relates to a novel Lactobacillus casei GFC1 strain (deposit number: KFCC18333P), a fermented ginseng extract using the strain, and a preparation method thereof. When the novel Lactobacillus casei GFC1 strain (deposit number: KCTC18333P) provided from the present invention is inoculated into ginseng and cultured, a fermented ginseng extract, of which the content of ginsenoside Rg2 is remarkably increased, can be obtained, by converting ginsenoside Re, contained in ginseng and having low bioavailability, into ginsenoside Rg2 having high bioavailability. In addition, the fermented ginseng extract has excellent skin antioxidation, skin whitening, anti-inflammatory and wrinkle reducing effects, and can control skin troubles, caused by a distribution imbalance between skin flora, by changing the community of the skin flora, thereby having an excellent effect as a cosmetic composition when the fermented ginseng extract is applied to a cosmetic base as an active ingredient. |
