I use retinol and BHA, and my skin is HYPERsensitive. From what I've read online, the microdermabrasion kits are gentle enough for even me to use. I would just stop using the other stuff a day or 2 before and after a microdermabrasion tmt. This is what I used to do when I would go to an aesthetician for Biomedic enzyme peels. You might want to do some additional research for your own comfort though.
Also, if it helps to know, I used the 40% lactic acid peel yesterday (stopped using my products the 2 days before), and barely felt it. I'm hoping to move up to the other strength in about a week, then the TCA peel in 2-3 weeks. I believe these are also safe (possibly safer than microdermabrasion) to use.
