The claim
A natural, free contour without bronzer.
What the evidence says
It is deliberate, uneven UV damage. Sun exposure without protection raises skin cancer risk and drives the pigment and wrinkle changes the sunscreen trials prevent. Uneven application also produces patchy pigmentation that is harder to treat than a tan.
Who should skip it
Everyone; especially anyone with melasma, a history of skin cancer, or a family history of melanoma.
What to do instead, or as well
Full-face sunscreen and a bronzer.
