The present invention relates to a medical prosthesis for alleviating skin wrinkles. More particularly, the medical prosthesis for alleviating skin wrinkle according to the present invention, is formed in wires comprising xerogel which can be compressed and dehydrated with a greater shrinkage rate in comparison to the shrinkage rate from a hydrogel form through a simple dehydration condensation, wherein the xerogel is recovered back to the state of hydrogel before compression by being inserted to human bodies and absorbing the water in human bodies. According to the present invention, the prosthesis is made of materials of PVA or PVAc, etc., and has excellent suitability to human bodies while being capable of maintaining an effect of alleviating skin wrinkles for a long period of time. Also, the prosthesis of the present invention is useful to plan a surgery with by having a simple computation of capacity or cross-sectional area for the prosthesis to be expanded, and has little cross-sectional area while remarkably maintaining the shape. Thus, the prosthesis can enhance applicability for a surgery. |
