What can i do to reduce acne?

ACNE: Drink a lot of water, fresh fruits, vegetables, make sure you are not constipated, reduce anxiety, get enough sleep, don't use strong soap, don't wash/rub your face too much, don't pinch acne, don't use too much make ups/creams, etc. Use meds prescribed by your physician accordingly.

Start with...: Topical benzoyl peroxide. If this does not clear it, your physician can add topical Clindamycin or another antibiotic; if it's on your trunk, you'll probably need a systemic antibiotic as well, and if it's severe, dermatologists have stuff that's not pleasant and a bit risky but is certain to clear you up. This is the 21st century and you have a right to be acne-free.
