The sun is never good for your skin
It's best to avoid the sun so that your acne can heal under the best conditions.
Right after tanning, you may have the impression that your spots are hidden and dried out. But you'll soon notice that they'll be back with a vengeance. Brown spots may also appear. In addition, some acne medicines can increase sun sensitivity, another reason to avoid exposure to the sun. If you have acne-prone skin, you should choose sun creams that are specially formulated for oily or acne-prone skin.
