Abstract: The transdermal permeation characteristics of VBE-1 in solution and suspension were investigated by Franz-type diffusion cell in vitro. The permeation and skin residual amount of VBE-1 were quantified by HPLC,and permeation kinetics parameters were calculated.The lag time was shortened and 24 h skin residual amount was increased by 35% in solution.Transdermal behavior of VBE-1 was optimized.Brownish guinea pig model was used to study the interference effect of VBE-1 gel on skin pigmentation induced by ultraviolet B(UVB)irradiation.The results showed that skin melanin increment of 2% VBE-1 gel was significantly lower than the gel base group.The UVB irradiation induced skin hyperpigmentation was interfered by VBE-1 at higher concentrations.

Key words: VBE-1, transdermal behaviors, skin residual amount, melanin, brown guinea pig
