Microdermabrasion is a popular noninvasive skin rejuvenation procedure that uses a mechanical instrument to gently sand the top layer of skin. This treatment improves wrinkles and fine lines, slow the appearance of aging, lessen the look of scars, marks and other blemishes, and reduce the appearance of stretch marks. This gentle exfoliation process also removes surface imperfections like age spots and sun damage, fading them over time, leaving your skin looking more even-toned and smooth.
