See a Dermatologist
When it comes down to it, nothing beats a one-on-one visit with a doc. In fact, a recent tretinoin/antiobiotic treatment prescribed by my dermatologist really helped to clear up a major bout of jawline acne I was experiencing. Many of you agreed that heading to the derm is the way to go, as well, especially reader abs0lutelyfab who said, "See a dermatologist, especially if you have cystic acne. The time and money spent on hoping on an over-the-counter cure isn't worth it."
