There is no safe or healthy way to get a tan from sunlight, new guidance from the National Institute for Health and Care Excellence (NICE) has warned.
The health watchdog’s latest guidance also says an existing tan provides little protection against sun exposure.
It recommends using at least factor 15 sun cream, with adults urged to use 6-8 teaspoons (35ml) per application.
Benefits from building up vitamin D from the sun have to be balanced with the risks of skin cancer, it adds.
The new guidelines highlight certain high-risk groups that are at particular risk, including those with outdoor hobbies, for example, sailing or golf.
Also, those with high, but intermittent, exposure to sunlight and who are therefore at increased risk of skin cancer. This includes people who sunbathe or take holidays in sunny countries.
