Faces, like khakis and the space-time continuum, look best when wrinkle-free. Iron out head creases with today's Groupon: for $79, you get a Vitalize chemical peel at Armonia Skin Care in La Jolla (a $200 value).

Armonia Skin Care helps clients refurbish dilapidated frontispieces with spa services that treat such epidermal maladies as wrinkles, acne, and sun damage. To slough off dead skin and polish the facial surface, epidermal experts apply the SkinMedica Vitalize peel, a blend of retinoic acid, peeling solution, and skin cell-chomping Pac-Mans. All skin types can benefit from the treatment, which can be customized to address specific mild to moderate skin conditions. Fine lines, acne scarring, melasma, and tread marks recede as smooth new skin takes the place of the old.
