ive tried a manual microdermabrasion. im afraid to use the electric sponge rotating thingy cause i would prefer to use a new new sponge after every application to prevent reinfection and more acne. the replacement sponges are pretty expensive and im sure you can get just as good an exfoliation with a cheap makeup application sponge and doing the circular mostion manually. it just takes a bit more effort.
if you are using the cream at home polisher then you need to keep in mind what kind of fomula you are using. i used the olay version and i found it just a bit too oily and i ended breaking out. and if you have acne and you use glycolic acid peels you might want to consider a a micodermabraison with glycolic acid already in the formula.
i found this thingy. someone was talking about it on another forum so i bookmarked it for future reference. it seems like a cute little toy. i would prefer to by something that is a little more professional but i dont want to sand blast my face off by accident. if anyone has used it let me know. my only problem is that the refills are so expensive.
