I have tried almost every spot treatment out there! And nothing worked! I have never had acne in my life up until about a year ago. Going from clear skin to uncontrollable adult acne can be rather frustrating! In the last year, I have not gone a day without waking up with ATLEAST one new pimple every day. And they would last for weeks and become very deep cystic acne. I would of course pop them-even tho I knew not too! They drove me crazy and I would... Being this stuff was pricey and nothing in the past year would work I was leery to buy this so I started with a sample. The morning after using this was the first morning in a year that I did not wake up with a new pimple! Not only that, but my scarring from popping my hundreds of pimples threw out the past year were about 25% smaller and lighter. The pimples I did have were half the size. 4 days into using this, my scarring was half the size and half faded and still no new pimples! The ones I had prior to starting this are now completely gone. Of course, I had to then buy the product as my sample ran out and I knew I could not got a day without it!! I cannot wait to see what this does to my skin in a weeks time, or a month, or a year! I will never go without this product! Finally I found something that actually works for both clearing acne and the nasty scars that are left behind!
