Is there a good home remedy to get rid of acne and scars ?

Will disappoint: Over-the-counter benzoyl peroxide is your best non-prescription rx. Nothing you can do at home will touch scars. If you are the patient are are avoiding a physician's office visit, that is your business, but if you are responsible for the health of a teen who already has scarring, you have a duty to get him/her effective treatment that only evidence-based medicine is likely to provide.
