After studying the effects of encasing the 10th scientist's head in a plastic cube, 9 out of 10 agree that a healthy human face needs oxygen. Maintain a majestic visage and a robust behind-the-skin scene with today’s Groupon: for $69, you get two microdermabrasions and two oxygen facials at Tatiana Esthetics in Etobicoke (a $340 value).

Under the direction of certified aesthetician Tatiana Gurova, Tatiana Esthetics strives to go beyond beautifying by delivering aesthetic services that nurture overall health and well-being. The microdermabrasion and oxygen facial revive worn-out mugs, leaving faces fresh enough to show genuine emotion instead of etch-a-sketching emoticons. The microdermabrasion (a $95 value/treatment) gently yet deeply exfoliates the top epidermal layer, which may stimulate collagen growth and result in a smoother, more glowing appearance. When administered as a preventive treatment, the microdermabrasion may also lend relief to acne-prone pelts. A relatively new treatment, the soothing oxygen facial (a $75 value/treatment) pushes pure oxygen into skin cells with the intent of boosting collagen and elastin production. It also seeks to heal aging accelerated by insufficient oxygen, most commonly caused by forgetting to take off a Halloween mask.
