How Microdermabrasion Works
The crystal microdermabrasion device consists of a compressor that draws in air through a hand-held wand. When the wand touches the skin, a vacuum is created. Aluminum oxide crystals, also known as corundum (the second-hardest mineral next to diamonds) blast across the skin’s surface, picking up dead surface skin cells along the way. The crystals and dead skin cells are quickly sucked up through a different tube in the same wand and go to a disposal bag.
The depth of exfoliation is controlled by the strength of the vacuum and crystal flow, which is determined by esthetician. He or she makes two passes over your skin, sometimes a third if your skin is thick enough or if there is an area that needs special attention, like a scar or brown spot.
Crystal microdermabrasion can be uncomfortable, especially around the sensitive tissue of the mouth and nose, but it should not be painful.
The esthetician should be checking in with you about your comfort level during the treatment. If anything hurts, speak up. The esthetician, who should be wearing gloves, a mask and eye protection, also leaves traces of the crystal on your face, which might be red afterwards. Your eyes should also be protected.
