Summary

Skin ageing is a complex process influenced by intrinsic and extrinsic factors, primarily ultraviolet (UV) light. Environmental changes significantly impact skin ageing and cancer development, though clinical advances lag behind molecular understanding.

Area of Science:

  • Dermatology
  • Gerontology
  • Environmental Science

Background:

  • Cutaneous ageing is a visible model of intrinsic and extrinsic aging factors.
  • Ultraviolet (UV) light is the primary extrinsic factor causing photoageing.
  • Skin contains numerous chromophores that absorb UV energy.

Purpose of the Study:

  • To review current knowledge on skin ageing.
  • To highlight the influence of environmental changes on skin ageing and carcinogenesis.
  • To discuss the molecular and biochemical aspects of skin ageing.

Main Methods:

  • Literature review of scientific articles on skin ageing.
  • Focus on the role of UV radiation and environmental factors.
  • Analysis of molecular and cellular mechanisms involved in skin ageing.

Main Results:

  • UV radiation significantly contributes to skin ageing and carcinogenesis.
  • Environmental factors play a crucial role in skin ageing processes.
  • Molecular understanding of skin ageing has not fully translated into clinical advancements.

Conclusions:

  • Skin ageing is a multifaceted process driven by intrinsic and extrinsic factors, with UV light being a major contributor.
  • Further research into environmental influences is needed to understand and mitigate skin ageing and cancer.
  • Clinical management of age-related skin conditions remains challenging due to incomplete understanding.
