Though best known for expanding the limits of human thought, the great philosophers were also ardent proponents of skin treatment—rarely furrowing their brows without first applying a de-furrowing cucumber mask. Wipe out your own philosophical furrows with today's Groupon: for $49, you get either a power peel, deep pore facial, or rejuvenation facial at TLC Laser & Skin Care Center in Oconomowoc (up to a $135 value).

A power peel begins with a thorough skin analysis before a 30, 40, or 50% glycolic-acid chemical peel and crystal-free microdermabrasion politely evict wrinkles, discolorations, and dull skin from fleshy face condos. The detoxifying deep pore facial employs microdermabrasion, steam, a clay mask, and extractions to collectively send blemishes the way of the dinosaur (back to outer space). The rejuvenation facial cooks up a cauldron of cleansing concoctions that includes skin-firming lotion, an antioxidant treatment, a vitamin-C mask, and microdermabrasion. Patrons will be pampered with a skin-hydrating and skin-refreshing treatment that moisturizes, boosts circulation, melts away stress, and removes clingy dryer sheets from last week’s laundry. After each 30–45-minute treatment, peruse a bevy of medical-grade skincare products, which can be purchased at the time of service for a 15% discount.

After passing through the door or diving headfirst through the storefront window, brace for a greeting from an experienced staff of wide-smiling specialists. Relax and soak in the soothing confines that feature earthy tones and lustrous finishes before melting away blemishes into a disposable puddle of bee-luring face nectar.
