Hi B.,
I've used a number of Microdermabrasion products over the years and I would recommend Neutrogena's Healthy Skin Rejuvenator. I've been using it for several months and I can see the difference.
I had acne as a teenager and I still occasionally break out. This system really deep cleans my pores and leaves my skin feelings freshed, smooth and clean. The best thing about this product is that it's available everywhere. It's at most grocery and drug stores like CVS, Publix, Kroeger and Walgreens. It can also be ordered online at drugstore.com and many other online sites.
I would encourage you to go to drugstore.com research Neutrogena's Healthy Skin Rejuvenator and read the reviews for yourself. It's a bit pricey up front but once you make the initial investment, the refills are pretty affordable.
Neutrogena also has an Advanced Dermabrasion Kit as well. You may want to check into that as well.
I hope this helps.
