BACK 2 x 50p blobs of suncream

‘The back is the most common area of the body where we see melanoma in men,’ says dermatologist Justine hextall. (For women, it’s the legs — see the panel on the far right.)

‘I take a lot of skin cancer off backs, and when you think that it’s not a particularly sun-exposed area for most of the year, that suggests people aren’t protecting it.’

You should use two blobs of suncream, each the size of a 50p coin, to ensure that your entire back is well-covered.

‘Remember that if you’re lying on a towel or sunlounger on the beach that is going to rub suncream off, so you need to frequently reapply similar amounts of cream in this area when you get up,’ adds Dr hextall.
