A few options. For over the counter methods try using products that have benzoyl peroxide, salicylic acid, alcohol, and acetone. For prescription treatments you may be prescribed antibiotics, retinoids or vitamin a derivatives, azelaic acid, oral contraceptives, or spironolactone. Always ask a dermatologist about the possible affects and the risks vs benefits of each treatment. Make sure it's best for you.
Start with OTC stuff. Start with otc stuff like benzoyl peroxide. If that doesn't work you may need something prescription strength. As always prevention is key so identify potential triggers and hopefully you can avoid them to keep it under control.
