Visible signs of ageing are the symptoms of changes that have occurred below the
skin's surface as a result of harmful external influences. These external factors
produce free radicals, which are the skin’s main enemy. They attack and break down
the skin's supportive structure, which consists essentially of collagen, elastin
fibres and moisture-retaining elements called polysaccharides. The results of this
degradation are fine lines and wrinkles, dry skin and uneven skin tone, to name
a few. Factors that contribute to the skin's deterioration are outlined below.
Sun
Approximately 80% of visible skin ageing is the product of UV light exposure. This
means that the sun and daylight have more effect on your skin than your body's natural
ageing process.
Hormonal Ageing
During the first five years following menopause, the skin loses up to 30% of its
supportive collagen fibres. As a result, the skin becomes thinner and the signs
of skin ageing accelerate. The skin becomes less capable of storing moisture, becomes
drier and "looser," wrinkles deepen and become more pronounced. The skin also becomes
more prone to damage caused by free radicals as the cell renewal process slows down.
Pollution
Airborne pollutants such as dirt and dust – present in most modern environments,
especially in densely populated or industrialized areas – are harmful to the skin.
Air-conditioning
Dry, air-conditioned or centrally-heated interiors dehydrate the skin, leaving the
epidermis dry, flaky and vulnerable. This dehydration damages the skin's barrier
function and promotes increased evaporation of dermal moisture.
Sleep
Sleep deprivation leads to a lacklustre complexion and dark, puffy under-eye circles.
Lack of sleep leads to skin that is prone to premature lines and wrinkles.
Stress
Our emotions can literally show on our faces. Anxiety and anger have been shown
to increase sebum production in the skin, while periods of calm significantly decrease
sebum levels.
Alcohol
Drinking in excess leads to significant skin dehydration and robs the body of vital
nutrients such as vitamins A, B, C and the minerals magnesium and zinc.
Smoking
Studies show that smoking reduces the supply of blood to the skin's surface, restricting
the flow of essential nutrients. This leaves the skin dull and greyish in colour.
Smokers tend to have thinner skin than non-smokers; therefore, their skin is prone
to the premature appearance of lines and wrinkles.
