I started using proactiv about a year and a half ago. I was working great until recently… i had SUCH clear skin and since about 3 months ago my face just has not been good! I think my skinhas gotten used to the proactiv, its not terribel acne but enough to be a bother. my mom bought this neutrogena stuff so ill start using that. anyone else have experience with that? or anything else that works well. thanks!
