A wrinkle is formed by muscular contraction is repeated many times or aging. That tissue around of wrinkle is different from other parts. It is important to know the influence which the stress gives to skin, in the viewpoint of the beauty or the treatment for the wound in plastic surgery. This paper presents a method of finite deformation analysis for combinative probrems in stress deformation of solid matrix and in permeation flow of fluid of a living soft-tissue. Living soft-tissue is consisting of two principle phases. This biphasic material with a solid matrix (collagen fibrils and elastin fibrils) and the interstitial fluid (water) has combination problems in stress deformation of solid matrix and in permeation flow of fluid. Thus we let the equation which combined the hyperelastic constitutive equation for skin and under-skin tissues with Darcy's law in permeation and continutive equation of fluid flow. The program was developed based on this equation, and simulation was done.
