Abstract

In this study, we investigated effects of the Strawberry plant body (SPB) extracts on the improvement of whitening and wrinkle. We confirmed effects of SPB extracts on UVB-exposed hairless mice to measure changes of skin conditions. The cream containing SPB extracts significantly decreases erythema index and melanin value on UVB-exposed hairless mice. Also, transepidermal water loss (TEWL) was significantly decreased in experimental group using cream containing SPB extracts on UVB-exposed hairless mice. UVB irradiation induces the expression of matrix metalloproteases (MMPs) in skin tissue. The up-regulation of MMPs enhances degradation of collagen and induces skin aging. The cream containing SPB extracts significantly decreases contents of MMP-2 and MMP9 on UVB-exposed hairless mice. These results suggest that SPB extracts might be used as a ingradient for improvement of whitening and wrinkle on UVB-exposed skin.
