yes you can incorporate it into your own regimen. I'd read up on the acne.org regimen and see where you'd like to add AHA into yours, see if they overlap. I emphasize baby steps when using it because it can, at least for me, cause irritation in the beginning.

If your skin is fine without the regimen and what you're doing is working for you, I don't think it can hurt to incorporate AHA  Especially if you're using it to clear up marks because it works really well for that (I had horrible marks but AHA and time really helped). As Geeking said, it's definitely recommended to start slow and mayb use very litte 2-3x a week until your skin gets used to it. It can sting a little at first. Good luck!
