Great question! They’re very different treatments. The Personal Microderm is a dermatologist grade microdermabrasion treatment. It uses a spinning disc embedded with aluminum oxide crystals to exfoliate away the entire top layer of dead, dull skin, and triggers the cell turnover process which tells your body to produce a new, fresh layer of skin! The vacuum suction increases the production of both collagen and elastin, while increasing blood flow to the surface of the skin. When you do this treatment weekly, you’re consistently removing the old, damaged skin and replacing it with new. This minimizes the appearance of enlarged pores, dark spots, hyper pigmentation,evens out skin tone and texture, fades fine lines and wrinkles, and by removing that barrier of dead skin your skincare can penetrate up to 20x deeper and be more effective. Microneedling uses tiny needles to puncture the skin, which triggers collagen production and the healing process. But it isn’t going to give you that heavy exfoliation.
