thank GOODNESS for ProActiv! I’ve been a faithful user since the early 90’s and my skin has been fabulous ever since… Some people have a hard time using benzoyl peroxide, and my skin was a little reactive at first, too, but now, if I stop using this miracle skin care, it goes right back to being 16 again… acne! Yucko… The stars are only for the product… most of the people that work at the kiosks do not use the products and are just typical mall workers. Don’t try to ask them any questions, because most likely they will not have the answers. I think there is an 800 number on the brochure that you can call with questions. I would trust them more. So, if you have oily acne type skin and have tried everything… give this stuff a try! it may work for you, too!
