Ageing Skin

There are 4 main causes of ageing skin:

1. Age - after the age 20 we lose about 1% of collagen in the skin each year.
    
2. U/V Light - exposure to U/V breaks down collagen and elastin fibres found in the dermis.
    
3. Smoking - can speed up the normal ageing process.
    
4. Repeated Facial Expressions - as the skin ages, it loses its flexibility and is less able to spring back into place, causing permanent lines and wrinkles.

Scars can form when the skin doesn't produce enough collagen while healing, resulting in depressions or pits. Sometimes the contents of the blemish spills into the surrounding tissue, causing deeper scarring.

A stretch mark is a kind of scar caused when the skin stretches or shrinks quickly. The quick change causes the collagen and elastin to rupture.

The main cause of enlarged pores is excessive sebum production, but it can also be caused by sun damage, aging and large hair follicles.
