I haven't tried Skin ID, but I recently read an article that talks about why Proactiv doesn't work, and why you should stay away from water-based acne products. It's called Proactiv isn't proactive - why water is bad
i agree ^^^. i used to use it,worked really well and face but redness never left,skin felt dry as wellProactiv can treat acne, but it will cause some redness too
