Been using this stuff after buying it from Amazon intermittently for about a month, and, when paired with the ampoule and the rest of my skin care regiment, it has done a ton of work in improving the appearance of my acne scars. They're so faded at this point that you'd have to be up real close to notice them. I'm sure by the end of February, I can be rid of them completely forever. Don't hesitate if you've got remediable facial blemishes that you're insecure about.
