The skin is a multifunction organ that is in a constant state of repair and maintenance. Skin damage is not always immediately visible and may not be seen for years. A ‘healthy look’ today caused by sun exposure will, in time, result in wrinkles and splotched pigmentation.
Fair skinned individuals are especially susceptible to skin cancer. Approximately 80% of skin cancers are related to exposure to the UV radiation of the sun.
The sun emits harmful Ultraviolet (UV) radiation, of 3 types: UVA and UVB (which penetrate the ozone layer) and UVC (the most harmful) which is absorbed by the ozone layer. Ultraviolet radiation causes damage to the skin through increasing production of free radicals, connective tissue and DNA.
Photo-aging damages the skin through excessive sun exposure and results in premature wrinkling, dry rough skin, freckles, and discolorations (age spots or lentigines).
Skin cancer is a result of DNA damage to skin cells.
Australia has one of the highest levels of skin cancer in the world, at 2-3 times the rate found in USA, Canada and UK.
