How to treat it in the short term: "The fastest way to treat individual cysts is with an injection of Ö corticosteroid by the dermatologist," Waldorf says. The cyst will usually go away in a couple days after being injected. If you can't get to a dermatologist, Waldorf says you can try a benzoyl peroxide or sulfur/resorcinol spot treatment, but know that it will take longer to disappear. (Try: Clean & Clear Maximum Strength Persa-Gel 10, $6.30 or Proactiv Refining Mask, $28.)
How to treat it in the long term: If you have frequent cystic acne, Waldorf says oral antibiotics and topical retinoids can be helpful. Other options include hormonal therapies like oral birth control pills. A dermatologist will be able to prescribe these medications and monitor your situation.
