Acne is a common skin condition causing breakouts of pimples. Acne is mostly caused by stress, hormonal changes and bacteria. It is important to sometimes treat acne from within the body in addition to treating the surface layers of the skin. Many over-the-counter products and popular products such as Proactiv only treat the immediate surface breakouts not reaching the deeper cause. Many of these products are not tested by the FDA for effectiveness. It is important to seek guidance from your skin care specialist or physician to determine which acne cleanser and treatment plans will be most effective.
