Facts about Skin Ageing

FACTS ABOUT SKIN AGEING

Ageing is the degradation of the dermis and epidermis over time that leaves the skin thin, lacking elasticity, wrinkled and pigmented.

  • Collagen and elastin production slows down a dramatic 65% between the ages of 20 and 80 years
  • The thickness of the skin decreases a staggering 6% every 10 years
  • 90% if the visible signs of ageing are caused by sunlight exposure

Intrinsic Ageing

Changes that would occur over time without the effects of environmental factors

Ageing is a process of gradual and spontaneous change, resulting in maturation through childhood, puberty and young adulthood and then declining through the middle years and maturity.

  • Intrinsic ageing is the process of normal ageing that is related to our genetic code
  • Genetics (imprinted in genes)
  • Stress
  • Smoking
  • Medication
  • Hormones
  • Diet

Extrinsic Ageing

Changes that are brought on by the effects of the environment and our choices relating to them especially sun exposure.

Degradation of collagen is the result of exposure to environmental hazards such as wind, severe temperature changes, sunlight, smoking and pollution

  • Sun
  • Pollution
  • Air-conditioning
  • Humidity
  • Very hot/cold conditions
  • Incorrect product use

Changes in the Epidermis

  • Changes in the formation and maturation of keratinocyte cells (prevents foreign substances from entering the body & minimise loss of moisture)
  • Changes in the functioning of melanocyte cells (causing pigmentation)
  • Changes in the efficacy of Langerhans cells (help regulate the immune system)
  • Influence on the changing over from keratinocyte cells to corneocyte cells which protects the underlying cells from UV radiation and DNA damage

Changes in the Dermis

  • Diminished collagen and elastin production
  • Negative influence on the production of GAGS (They play a crucial role in the cell signalling process, including regulation of cell growth, proliferation, promotion of cell adhesion, anticoagulation, and wound repair.)
  • Appendages are adversely affected due to weakened connective tissue (repair damaged tissue, transport nutrients, etc)
