I was skeptical to try this - after all its just a collection of different soaps, and very expensive ones at that. They are of course different from what many acne treatments contain, and it is their combined use that creates good results. As the other reviewers have noted you need to continue using this and remain... proactive. I've tried several topical and ingested acne medicines before, and have very oily skin. The combination of soaps and treatments in this set have noticeably reduced my skin's oiliness and this has resulted fewer and less sever breakouts. I'm using it once daily, shaving in the morning and applying it at night. Though it is a concern that some of the chemicals can bleach your towel and pillow cases (and anything else) I haven't noticed any rub-off or transfer - just let it dry and/or switch to white colors and you'll be fine.
The only major drawback to this package is of course the cost - it's far beyond any other type of washing treatment, but at the same time it's not an antibiotic (which really isn't good for you) and so its worth it for the results. It is a little time consuming compared to other washes.
Also, there are no instructions except the small print, many times underneath sticky labels on the containers. It's a pain to get to them the first time, but once you have the routine down it's no longer an issue. --Wash with the "Renewing Cleanser", rinse and pat dry, apply the "Revitalizing Toner," allow to dry, apply the "Repairing Treatment" allow to dry for a while, then apply the moisturizer as needed - probably a good idea since if you're using this product you probably have sensitive skin and mine felt by touch like I had a sunburn after a couple days. I only used the mask once, before doing the normal routine, it seemed to work, but again the lack of clear instructions leave me wondering...
Overal, while it is pricey, it is well worth your time to at least try it for one month (longer if one treatment a day) and see if this works for you. The benzoyl peroxide that this product relies on can perhaps be replicated by following an online guide, but with one application a day this lasts two months, and I'm happy to spend $20.00 a month to reduce my acne - that's dinner and a movie these days.
