Which is better: a peel or microdermabrasion?

Both shed dull, dead skin cells, revealing a more glowy complexion. But the former does so with liquid exfoliants such as glycolic acid, and the latter uses gritty materials such as small crystals, says Marsha Gordon, M.D., a dermatologist in NYC. Professional versions of each (about $200 per session) provide speedier results than do-it-yourself kits. But the time difference is so small—only about a month—you may want to opt for the cheaper (as low as $8), no-appointment-necessary option. In that case, try at-home microdermabrasion. "Peel strengths vary from product to product, making it easier to overexfoliate," Dr. Gordon says. Microdermabrasion textures are pretty consistent across the board. Use twice a week for two months to see prolike results.
