[Reconstruction of the skin structure of the aging].

Abstract

Based on the character of degeneration and change of the aging skin, reconstruction and repair of the skin structure are performed with a method of subdermal incision in order to increase the content of collagen protein and replace the degenerates collagen in the dermis. The animal experiment shows that the treated skin contracts by nearly thirty percent (P < 0.01) at 15 days after surgery. The epidermis becomes thicker and the dermis contains more fiberoblasts and collagen than that of preoperation. Seven patients were treated with the method. Afterwards their crow's feet deformity and the wrinkles of the nasolabial groove almost disappeared.
