Associate Professor Rosemary Nixon from the Skin & Cancer Foundation Inc. says: “Don’t be lured by the prospect of the ‘healthy tan’ this summer – there’s no such thing. Overexposure to the sun has been identified as the cause of around 99% of non-melanoma skin cancers and 95% of melanoma in Australia.”
Terry Slevin, education and research director at Cancer Council WA says, "to get a tan, you have to get a level of UV exposure that creates a biological change in your skin. And that, by nature, will increase your skin cancer risk."
The UV exposure is by far the greatest cause of skin cancers. The ability to tan is an adaptive response to the stress of your skin being exposed to more sunlight than it can handle. It is your skin's way of protecting itself against UV that can damage the genetic material (DNA) in skin cells, potentially triggering skin cancer.
Even if the skin is naturally brown rather than tanned, it doesn't mean it is bulletproof in the sun: "While we do delineate levels of risk based on skin type, Melanoma and other non-melanoma skin cancers can still occur in people with darker natural skin pigmentation. No-one is immune." says Slevin.
Research shows that tanned skin does not provide adequate protection. Experts recommend using a sunscreen of at least SPF30 to protect the skin.
The exposure to UV that causes tanning also accelerates skin aging and causes the skin to become wrinkled and less elastic. As much as 90 per cent of premature skin aging – such as sunspots, wrinkles and fine lines – is believed to be due to sun exposure.
Apply and re-apply sunscreen regularly, wear sun protective clothing that covers large areas of the skin, wear a broad brim hat and sunglasses and seek shade when possible.

Your skin is your largest organ and has a long memory. Sun exposure and ultraviolet (UV) damage is cumulative throughout your life. Research shows that sun damage contributes to more than 90% of wrinkles, brown spots, premature skin ageing as well as precancerous and cancerous skin lesions.
Limiting sun exposure is very important. As the UV rays cause the most damage to the skin.
It often takes many years and sometimes decades for the effects to become visible.
But the good news is that taking care of your skin form now onwards may be able to help you to reduce the probability of skin cancers and minimise skin ageing.
Dermatologists recommend UPF50+ sun protective clothing and a broad brim sun hat as the first line of defence against premature skin ageing, sunburn, skin cancer and melanoma. Sunscreen with a SPF rating above 30 should be applied to skin that is directly exposed to the sun.
