Exposure to the sun every other day produces more skin pigment than sunbathing every day – but protection is still vital.
Professor Fabian V. Filipp lectures on the biology of malignant melanoma and pigmentation disease. The color of skin is due to the presence of a pigment called melanin, which can absorb cancer-causing sunlight.

An international team of researchers is probing the links between skin diseases, including cancer, to speed the search for cures.
Different skin tones need different amounts of UV light to activate vitamin D in the skin.
UV ratings indicate risk of skin damage – but they're based on pale skin. New wrist bands designed for six different tones of skin provide a more personalised way to track safe UV exposure.
Bright sun and fatty foods are a bad recipe for your DNA.
Scientists have long thought that regions of DNA called telomeres control how long you live. We are now learning that it is your diet and lifestyle that shape your telomeres, not the other way around.
England's out of the World Cup, but the UK can at least enjoy the weather... can't it?
Ingredients in many sunscreens are bleaching coral and harming marine life.
Scientists have discovered a natural sunscreen – made by microbes – that may be better for humans and the marine critters they are hoping to see.
White people are not made for Australia’s weather conditions.
Most Aussies think we have such high rates of skin cancer due to an 'ozone hole'. But that's not the case. Here's why we have nearly a million cases of skin cancer per year.

Whenever summer rolls around, it's easy to forget the basics of sunscreen. How long should I wait after applying it to go in the sun, and how long can I stay in the sun with it on?
The study looked at helping redheads to tan and protect them from the sun. But the redheads were mice, not humans.
A US study into whether a new drug can give us a tan without going into the sun generated headlines around the world. Here's what the study really says.
Albinism is an inherited condition that affects the pigment of the eyes, hair and skin.
Tanzania has one of the highest rates of albinism in the world. The media in the country has an important role to play in protecting them from harm.

Energy from the sun's rays can cause skin damage and cancers. Sunscreens can absorb or reflect the dangerous UV light. Here's how it works.

Melanoma, the deadliest form of skin cancer, can usually be cured when caught early. When it has spread, however, it becomes a challenge. Recent findings are bringing hope. Here are a few examples.
Machines don’t make the same errors as humans when it comes to decisions based on visual analysis.
The value of machine learning is not only that it is more accurate than humans. It is also cheaper and more consistent in its diagnoses.
A ‘melanotanner’ monitors progress in selfie photos. But what effect might this fad have on years of anti-tan messages?

Melanotan helps to accelerate the production of melanin, the pigment that absorbs ultraviolet radiation and gives skin its colour.
Age-standardised cancer death rates have been falling in Australia.
Currently, seven cancer types are listed in the top 20 causes of death in Australia. These are cancers of the lung, blood and lymph, bowel, prostate, breast, pancreas, skin and some childhood cancers.
Although skin cancer is preventable, South Africa still spends millions on treatment.
Skin cancer – which is preventable – costs the South African health system more than is necessary.
This body map brings together evidence on proven cancer causes. Using credible, scientific sources it answers questions about whether alcohol, red meat or sun exposure increase your cancer risk.

The risks of UV radiation exposure are well-known, but some scientists are exploring lesser-known benefits of UV light.
In many parts of Africa skin lightening is a popular practise despite the health risks associated with it.
Unregulated over-the-counter skin lighteners can have detrimental effects on the men and women who use them. So why are governments in Africa not taking steps to ban these products?
