Some people say that sun exposure can help acne, but this is a myth. While a tan may cover up the redness associated with acne, it won’t clear up the acne itself. Also, UV rays are much more dangerous than pimples. So you shouldn’t use them as a “natural” treatment. Always wear sunscreen, and be sure to use protective clothing, hats, and a stronger SPF if you’re outside during the sun’s peak hours.
