I have lot of acne. what should i do?

Manage it: If topical benzoyl peroxide / retinoic acid / salicylic acid has not cleared you in two weeks, get with your personal physician who can add prescription-strength Rx. Ignore all the pop advice. Your disease is not related to lifestyle, sexual activity of any kind, diet, or hygiene. It's also a major personal and professional liability that you need to manage now. Best wishes.
