The funny part about aha is that it is so powerful that you can not use too much but at the same time the reccommended dose does not cover the whole face. In my opinion aha is a wonder for evening out complexion but only okay in moisturizing. What I would reccommend is what Dan and many of the aha vets on here do is to mix the recommended dose or a little bit less of aha into the moisturizer (you can use less moisturizer if you want). Dan has a blog article about it.
Personally I find aha can be too powerful for more sensitve areas like around my mouth as I notice it sometimes breaks me out. So my nightly routine when I used aha (once every few days during my first year of the regime) wash, wait 10 minutes, bp, wait ten minutes, aha on cheeks and forhead, wait five to ten minutes then put a healthy dose of moisturizer around mouth and a bit over aha regions.
Personnally I think if you still have actives then you should not use aha just yet, wait until you are clear of acne or it least above 90% clear and then use aha when you are attemting to even out your complexion. I believe aha causes more irritation to actives.
