Most here giving advice are doing it based on personal experience and what they've learned here and elsewhere. It is important to cite where your information is coming from. There is no single scientific answer to questions such as How do I get rid of acne? or What is the best way to combat male pattern baldness?
Please remember that what works for someone else might not work for you. In fact, acne treatment is a touchy area. What helps my skin might make your skin worse, and vice verse. Keep an open mind, but start any treatment with caution. Consult your doctor before using prescription medications...even if not condoned, they can still offer assistance (such as blood work).
