One of the most common facial skin problems for adolescents is acne, a troubling skin condition that can affect confidence and self-esteem. As sebaceous glands become over active and produce excess oil, follicles become plugged, resulting in blackheads and white-heads. These plugged follicles can then become inflamed, causing pimples, nodules and cysts. Although acne is not harmful to health and will usually go away after time, moderate to severe acne can leave scars. There are several acne treatment options available that can effectively treat acne and eliminate or reduce the scarring it causes.
