      When your skin is exposed to the sun, it can become dry and irritated. This can trigger your skin to make more oil. Sun exposure also raises the risk for acne scaring. Many acne treatments also make the skin vulnerable to UV damage. You should avoid spending a long time in the sun. When you do have to be in the sun, be sure to use sunscreen that is oil-free.
