How can I get rid of chest acne?

They're called "breasts"

Try spraying colloidal silver solution on it several times a day. Or leave a clean cloth saturated with colloidal silver on it all night every night until it clears up.

Green clay, jojoba oil, and saliylic acid. Look up the OCM. You have to do it twice a day consistently. You should see results in a month, but you can't stop.

Try using face wash and exfoliators on the affected area. Has worked for me in the past

Proactiv
