This is a randomized controlled single blind clinal trial that designed to observe whether the transplantation of autologous stromal vascular fraction (SVF) in adipose tissue is safe and its effect on improving skin regeneration.~The clinical trial will concentrate on the therapeutic effect of SVF after facial injection. After 1, 4, 8, 12, 24 and 48 weeks of treatment, a comprehensive examination of the facial skin was performed to assess the effect of the SVF. Skin texture, thickness and colour will be observed to evaluate the effect of SVF on skin regeneration
The purpose of this study is to observe whether the transplantation of autologous stromal vascular fraction (SVF) in adipose tissue is safe and its effect on improving skin regeneration.
