To attain the rosy glow of flushed cheeks, 18th-century ladies often took snowballs to the face, nuzzled fire-ant hills, and bench-pressed child princes. Give your complexion a painless glow with today’s Groupon: for $42, you get an Éminence organic 75-minute facial treatment at Beauty Mark Esthetics (an $85 value).

Beauty Mark Esthetics' experienced spa professionals brighten visages with the Éminence Organic Skin Care line, concoctions handmade from Hungarian ingredients such as fruits, herbs, and vegetables, and free of harsh chemicals and animal byproducts. The 75-minute treatment begins with a light cleansing and toning, freshening faces with the vigour of a minty-breathed window washer. After a pear-and-poppy-seed microderm polisher or rosehip-and-maize scrub exfoliate away defeated skin cells, aestheticians apply an intense peel made from blueberries, paprika, or pineapple enzymes, depending on skin type and ability to pronounce "quinoa." A massage completes the relaxing experience and facilitates lymphatic drainage and toxin exile.
