This review explores skin aging mechanisms, focusing on how ultraviolet radiation causes photoaging. It details treatments for preventing and reversing these aging effects.

Area of Science:

  • Dermatology and skin aging research.

Background:

  • Skin aging is a complex process influenced by intrinsic factors and extrinsic factors like UV radiation.
  • Understanding skin homeostasis and aging mechanisms has advanced significantly.
  • Ultraviolet radiation is a key contributor to photoaging and skin diseases.

Purpose of the Study:

  • To review the mechanisms driving skin photoaging.
  • To discuss the pathophysiology of treatments for photoaging prevention and rejuvenation.
  • To familiarize participants with photoaging treatments and supporting evidence.

Main Methods:

  • Review of current scientific literature on skin aging and photoaging.
  • Analysis of the biological mechanisms underlying skin aging.
  • Examination of the pathophysiology of various anti-aging treatments.
