Like fall leaves, collections of old, dry skin cells attract foraging animals and produce an earthy aroma when set on fire. Clear away last season's facial foliage with today's Groupon: for $65, you get a SilkPeel microdermabrasion treatment from Northwestern Memorial Physicians Group at its Lincoln Park location on North Halsted (a $135 value).

Northwestern Memorial Physicians Group is a professionally packed team of well-being warriors including experienced estheticians and physicians on the medical staff at Northwestern Memorial Hospital as well as faculty at Northwestern University Feinberg School of Medicine. Seven different physicians collaborate with two clinical estheticians to create dullness-quashing skin regimes. The 30-minute, physician-supervised treatment begins with a Clarisonic cleanse, which uses sonic frequency to eliminate surface dirt and oil to prep for better product absorption. Next, your esthetician will match you with a topical treatment serum selected from an arsenal of cosmetic crime-fighting agents that address a variety of skin concerns, including oiliness, dryness, and redness. The SilkPeel system employs a mug-snuggling closed-loop vacuum to infuse the face with serum benefits, evening tone and texture without the use of crystals, other abrasive particles, or driveway gravel. Each complexion-perfecting session ends with a calming treatment mask, moisturizer, and sunscreen, leaving patients with light-reflective skin that sends damaging rays bouncing away in shame.
