Performed by facialists and derms, microdermabrasion uses tiny crystals to remove the outermost layer of dead skin cells, leaving your face baby-smooth and ready to absorb your favorite serums and creams. Don’t want to fork over $70 to $200 for the treatment? The handheld PMD lets you go DIY, albeit while targeting a smaller surface area and with somewhat less power than a pro treatment. It feels a bit like a cat’s tongue is licking your skin — slightly rough but not at all painful — and you’re done in a few minutes. Just be careful not to overdo it at first. Too many passes can leave skin looking a bit too resurfaced.
