Can you tell me a good and easy way to clear acne ?

Forget "easy": Topical benzoyl peroxide 5% 2x/day isn't pleasant but it's what you should start with. If you're not clear in two weeks, be tough and phone your personal physician; you'll need prescription-strength treatment. If the easy meds fail and you're offered isotretinoin, consider accepting. Nothing in this life that's worthwhile comes easy. Knuckle down and you can do this.
