Abstract

DA-3711 is a novel, anti wrinkle agent containing growth factors derived from human skin culture. In this study, effect of topical application of DA-3711 on chronic ultraviolet B (UVB)-induced skin damage was evaluated in hairless mice model. Exposure to UVB for 8 weeks induced apparent wrinkles on the back skin of the mice. The dorsal surfaces were exposed to UVB for a further 8 weeks, during which the surfaces where treated daily by topically application of a lotion containing either 35% or 70% of DA-3711. For comparison, lotion base, lotion base containing Cylasphere Retinol(equation omitted) (2500 I.U., Coletica) and NouriCe $l^{(R)}$ (Biozhem) were applied topically once a day for 8 weeks.(omitted))
