I've been loving Trophy Skin's Rejuvaderm, an at-home microdermabrasion device that brings the spa to you with a combination of diamond-tipped exfoliation and suction technology. Here, I show how simple it is to change the device's filter and introduce our Trophy Skin Filter Challenge! Don't forget to snap a shot of your used filter and share on Facebook, Instagram or Twitter with the hashtag #ShowDirtyFilters so we can see who is getting the best results from their microdermabrasion device!
