I'm now 33 and I've suffered from moderately severe cystic acne since my early teens. I have tried literally every product you can buy in drugstores and Proactive (which was awful). This is the ONLY product that has ever worked for me.
It's a little bit pricier than some of the drugstore alternatives but it is WORTH EVERY PENNY (I usually stock up on several kits at a time when it goes on sale and I've found Walmart to be the cheapest place to buy it). I will never use anything else ever again and have recommended this product to all my friends and sisters who have similar problems.
The cleanser is great and scent-free. I sometimes feel a slight tingle after applying, but nothing strong enough to be painful - and I have sensitive skin. Leaves your skin feeling soft and clean.
Since using this and switching to mineral makeup my breakouts have almost completely stopped and I can go weeks with clear skin (a first for me!). Even when my hormonal cystic acne pops up at that certain time of the month, this product clears it up quickly - if I don't irritate my cystic acne by picking at it (hard to do!) my makeup covers it up beautifully (I use L'Oreal True Match Naturale mineral powder - also a little pricey but totally worth it!) and only I know it's there. Using Pro-X Clear gets rid of my cystic acne within a couple of days and since I've started using it more than a year ago my post-acne discolouration has faded to practically nothing!! (again, something I'm now able to cover up with mineral makeup - something I was never able to do before)
In my opinion this is by and far the BEST acne cleanser system you can buy and I've tried them all. For the first time in my life I have clear skin and that makes the small expense of buying this system worth every cent.
