When I ordered proactiv I got very mild acne. Mostly hairline pimples and occasional chin zits. Proactiv felt nice at first, but then it started to make me get zits in places I had NEVER had problem skin before (along the sides of my cheeks... outwards from my mouth... the space in between my nose and my lip. I finally decided that this system was not working for me. Instead, I bought some spectro jel and some Yon-Ka moisturizer for sensitive skin in the hopes of healing and soothing my burning skin... now... like many of the other reviewers, I have a painful rash on my cheeks. It looks like acne, but it is really just raised, red and painful marks along the side of my face. I only stopped the system this past week, so I'm hopeing that this is a reaction to a change in product and won't be long-term. I'm scared from reading the other reviews that it will be. If you value your skin, please do not buy this product. It is not only a scam, but it can actually DAMAGE your skin.

This stuff does work, and it has worked about 10 times better then anything I've ever used. Personally, it doesn't work as good as the commercials, but still more effective then other ones. IF you use it EVERYDAY, your skin will clear up. BTW the refining mask is GREAT.

I had mild acne but I wanted to have clear skin like the commercial. I noticed after a week my neck would itch and burn really bad. On week 3 of using the Proactiv I develope a rash all over my neck. I went to the doctor and I was advised to stop using the product. Once I stopped that rash gradually went away.

I guess if your desperate give it a try it may or may not work though!

I like Proactiv, but I have mild/moderate cystic acne, and it has done little for the larger bumps. It did improve my skin; it just didn't completely clear it. I don't think it's strong enough for cystic acne.

I have been a LONG time user. This is in my opinion essentially the greatest BP product to ever exist. In simple, it works. The reason why it works is because the formulation lends toward absorption. Many other BP products just sit on the surface and end up crusting over. This BP is mixed into a moisturizing base. Not only does it absorb, but it does not overly dry. It will irritate slightly at the beginning as will most anything that your skin is not accustomed to. Over a short time it will subside especially if you follow the recommended doses. Start small and work up to the full coverage amount. Another aspect of this product that I love - that is also true about everything Daniel Kern produces - is that it is sold in larger quantities for a much more reasonable price than anything else you can get over the counter. It makes you feel like you can actually use the quantity needed and not break the bank.

I am a man who has been using the Acne.org BP treatment for almost a decade now and looking to move on to something else. It's difficult for me to rate the product alone, when it's part of a larger routine, but I will do my best. 2.5% BP works well against active acne, quite well. I'm someone who has active acne and acne scars. As I type this, I currently have 3 fading pimples that were extremely large. This still happens nearly a decade later, but 90% of the time when my routine is perfect (as in I use the treatment 2x a day for 1 month), I will not have any active acne. The biggest short coming is that the treatment demands perfection. Any missed application means that I'm going to have active acne appearing in a day and resuming the routine won't stop that from happening. I don't want to use the phrase "wasted time" lightly, but it does feel like I wasted time with BP when I could have been using a superior product and have better looking skin now. It does very little for acne scars (not that I expect it to, but I want others to know). My skin with the treatment and a cleanser +moisturizer, does not look great. I have blackheads, I have enlarged pores, my acne scars are visible, and my face still sometimes will get that burning sensation and feel overly tight from the BP. BP is just for active acne in my eyes and nothing else, but it's strong enough that it limits what other products you can use in a routine. I saw someone in another review mention it, but efficacy wanes QUICKLY. 2.5% BP has maximum efficacy in the first month and there is a steep drop off after that. I do not recommend a bottle passed two months, which means more money being spent. The last negative point is that 2.5% BP bleaches everything. A very small amount getting on my hair over the course of a couple months means that the front of my hair is going to look bleached. People cutting my hair ask if I bleach it because of the treatment. I make that my hair is back when I apply it and this still happens over time. It will also bleach clothing and bedsheets if you're not careful. Overall a light 3/5 stars. It works well enough for active acne, but the downsides like hair/clothing bleaching, being highly addictive to the skin, demanding a perfect routine 2x a day, and quickly waning efficacy of the treatment, all make it lose 2 stars.
