From someone who has had acne prone skin her whole life, this product really is a game changer. Despite its price tag, this stuff works. Not only does it help clear up back/chest/body acne, it also helps with my Keratosis Pilaris--which is almost non existent now. It takes steady use, and make sure you hydrate after using (especially if you live somewhere dry). But Murad has found another loyal customer with this one.
