AGEING SKIN & PHOTOAGEING
Skin ageing results from biological changes in the epidermis, dermis and hypodermis. In the epidermis, barrier function is reduced causing an increase in transepidermal water loss (TEWL). TEWL is the di usion of water from the blood circulation through the dermis and epidermis finally to evaporate at the surface. Skin cell turnover slows causing dryness and there are pigment production changes, aggravated by sun exposure, leading to uneven skin tone.
TYPES & TRIGGERS OF AGEING
1. Collagen depletion.Thinning of the dermis leads to lines and wrinkles
2. Free radical damage. Pollutants and ultraviolet radiation produce free radicals which cause our skin to weaken and become dull.
3. Slow cellular turnover. Leads to dull and thinning skin.
In the dermis, collagen, elastin, and hyaluronic acid levels decrease leading to reduced firmness, elasticity and hydration. This results in fine lines, wrinkles, dullness and decreased skin tone.
Hypodermis ageing is marked by the loss of fat in the face, which leads to decreased fullness, sagging skin and wrinkles.
Ageing of the skin can be divided into 2 categories: intrinsic and extrinsic.
Intrinsic ageing, known as natural or chronological ageing, normally begins in our mid-20s and is determined by genetics.
Extrinsic ageing accounts for up to 90% of skin ageing and is largely controllable.
The most common causes are:
• Sun exposure - the major cause, often referred to as photo ageing.
• Pollution and environmental stressors
• Lifestyle choices, such as smoking and alcohol consumption
The good news is that you can reverse some of this damage and prevent future negative effects on the skin.
