I read about this new cream, currently being tested to give the wearer a tan without the need for sun. It works by triggering the body's natural melanin response to sun. It is said that it may help to prevent skin cancer.
Skin cancer is said to be dramatically rising in recent times.

Is this a good way of combating skin cancer while getting a tan?
