This study is related to develop a snail extract through a snail secondary fermentation process, getting anti-aging activity with healthy and beauty skin care scientific applications. In order to obtain a primary fermentation was incubated with Hericium erinaceus mycelium. Through the secondary fermentation process using Leuconostoc mesenteroides, was deeply described a total process of obtaining second fermented extract using snail body. Mycelium is applied in this study was extracted using Hericium erinaceus mycelium and Leuconostoc mesenteroides. The final yield of the extract was 62 wt%. Experimental results of secondary fermentation snail extract were contained with 32 wt% water, 31.5 wt% total amino acid protein, 15.7 wt% polysaccharide, 12.3 wt% fatty acid and others 8.5 wt%. In addition, in order to study about skin beauty care and anti-aging activity, we evaluated antioxidant activity with DPPH, elastin enzyme (elastase) inhibitory activity, tyrosinase inhibition rate, collagen synthetic function, fibroblast synthetic activity. First; anti-oxidative activity of secondary fermentation snail extract (IC50%) was spent with 7.27 mg/mL, control samples were spent with green tea extract was 11.8 mg/mL, common snails extract was 15.7 mg/mL, DL-a-tocopherol was 9.25 mg/mL respectively. Second; elastin enzyme inhibitory activity of secondary fermentation snail extract (IC50%) was spent with 32.5 mg/mL, control samples were also spent with green tea extract was 45.9 mg/mL, general snail extract was 67.7 mg/mL. Third; tyrosinase inhibitory activity of secondary fermentation snail extract (IC50%) was spent with 140.3 mg/mL, control samples were also spent with green tea extract was 250.7 mg/mL, general snails extract was 389.5 mg/mL, niacineamide was 125.9 mg/mL. Forth; fibroblast synthetic activity of secondary fermentation snail extract was increased with 125.6%, control samples were also spent with green tea extract was 98.9%, general snails extract was 109.5%, niacineamide was 125.9 mg/mL, DL-a-tocopherol was 96.2%. Fifth; collagen synthetic activity of secondary fermentation snail extract was increased with 118%, control samples were also spent with green tea extract was 87.3%, general snails extract was 93.2%, adenosine was 127.9%. In conclusion, on the basis of this study, in the future it is expected to be applied to the skin beauty care application and development of Korean style cosmetic products.
