I went through my 2nd BBL (Broadband Light) laser treatment a couple of weeks ago, and just had my second microdermabrasion yesterday. My final BBL laser treatment is in a week, and my final microdermabrasion 2 weeks after that. Well, hopefully anyway! Depends on how good the 3rd treatment goes! 

Prior to the treatments, I read that you have to be really gentle with your skin - no rubbing, tugging or trying to peel the healing spots off or things could look worse. Also you aren't allowed to use certain acids - mainly from what I gather you can't use acids that aid in exfoliation. I still didn't know quite what to expect or how my skin would react.
