Acne is perhaps the most affecting beauty issue to any teenager who is going through puberty. Though the exact cause of acne is yet to be determined, it is widely believed that the “zits” or pimples are caused by the effects of hormones on sebaceous glands. What affects teens more, sadly are the after marks or scars that acne leaves on the skin even after one has been treated. These scars can cause a real embarrassment for anybody to show their face in public.
