title: [Transfer of autologous fat and plasma : The future of anti-aging medicine?].
abstract: BACKGROUND
  Aging is a complex process driven by endogenous and exogenous stimuli. The distinct cellular and noncellular components of skin and adjacent connective tissue are constantly and irreversibly degraded during aging.
  
  
  OBJECTIVE
  The aim was to provide an overview of the biology of skin aging and the therapeutic options for rejuvenation.
  
  
  METHODS
  A review of the current literature and a demonstration of autologous fat transfer and platelet-rich plasma (PRP) are presented from a clinical perspective.
  
  
  RESULTS
  The aging process affects cellular components and the extracellular matrix (ECM); thus, the first stage is the degradation of the ECM. The loss of skin elasticity is induced by a breakdown of fibers such as collagen, elastin, or reticulin, whereas the degradation of proteoglycans results in decreased turgor and skin hydration. Synthetic filling agents primarily compensate for volume loss, but do not rejuvenate biologically. In contrast, the transfer of autologous fat and PRP is based on activating stem cell populations and growth factors, in addition to providing volume to target regions.
  
  
  CONCLUSIONS
  A profound comprehension of the cellular and molecular mechanisms of aging is important in anti-aging medicine. The transfer of autologous fat and PRP offers interesting alternatives in the sense of more biological skin rejuvenation.
