Over time, this has definitely my go to product in the Acne.org product line. Now that the regimen has kept my skin clear, I use the AHA+ more often to help with the inevitable signs of aging, especially in my forehead area. It also helps to maintain moisture and keep my skin in check when I don't have an opportunity to get in the full regimen. I absolutely adore AHA+ and am ecstatic that it now comes in the 16oz bottle. The 8oz lasts me forever and now I really don't have to worry about running out with the 16oz.
