I have pcos ..there's a lot of pimples bubbling on my forehead n back ..how do i remove those?

Will need serious Rx: Acne on the trunk for whatever reason usually does not respond well to over-the-counter remedies, and "folk" remedies will disappoint you. Benzoyl peroxide as you can tolerate is your best friend until you are able to be seen by your physician for prescription-strength rx. Fitness, sensible eating, and perhaps the oral contraceptive pill will perhaps help long-term.
