I've been wanting to try microdermabrasion forever now, but never could cough up the money to do it. I tried Mary Kay's and it is amazing! After one use my skin was the smoothest it's ever been, and now after two months, my pores are smaller, my skin color more even. They use the same minerals as the spa's for a portion of the price! One bottle will last 3 months. I have nothing bad to say about it!
