Proactiv has been wonderful for me. Normally I have chronic, constant mild acne on my neck, chin and cheeks and the area to the sides of my nose. I've used Proactiv for 2 years incorrectly, and finally started the complete program (wash,toner and healing lotion). Since then (3 months ago), I've been acne free. Whenever I stop using it, the bumps begin coming back. Since I've experimented with the 3 fundamentals a lot (trying just the wash alone, or the toner alone, or the healing lotion alone), I'm confident that the healing lotion is what has the maximum impact. Even if I'm too tired to wash my face at night, I at least throw on the healing lotion now.
My good friend also started using it 2 months ago and all the bad acne (at age 35) along her chin and jawline cleared up immediately.
This has been a product that really does what it says. I wish I had started using the healing lotion at night 2 years ago, but I was afraid of it being "too drying" etc etc and as a result I had 2 years of bad skin. Stupid girl. It isn't too drying at all.
The only problem I've had is with the toner - it can cause my chin and mouth area to become temporarily red and blotchy for 5 minutes, so I only use it once a day.
