I just started getting really bad acne on my cheeks out of nowhere 2 months ago and I'm 22. Keflex and Minocycline don't work. Swelling has started?

Dermatologist ASAP. Some acne is resistant to antibiotics. Other treatments are available, but require specialist care. If you're not under care of a dermatologist, ask for referral to one right away. Prompt treatment may be needed to prevent permanent scarring. With modern treatment, nobody should ever have to deal with that lifelong problem. Good luck!
