I've used this system successfully, and I've had good luck with most of these proactiv type three step programs. this one has quite a bit of alcohol in the toner which I dislike. you can get the walmart equate version or actual proactiv ones that are alcohol free and have glycolic acid. the amount of BP is a bit higher in this system than in others, I believe it is 3.7 percent. they have a sensitive skin version that has an alcohol free toner and a cleanser with salicylic acid rather than benzoyl peroxide, but I haven't tried it myself. I would recommend having a good moisturizer on hand for the times or areas this might dry you out because it will eventually. I like the lotion type benzoyl peroxide treatment in these kits because it isn't as drying and my skin doesn't take kindly to most moisturizers (the search goes on). this is inexpensive and effective, so long as you don't have an allergy and go easy starting out with the products you will get good results with it.
