Eyebrows excel at nonverbal communication—rising incredulously, lowering in anger, and freezing flat when slathered in peanut butter. Reshape silent signals with today’s Groupon: for $8, you get two eyebrow-threading sessions at Annie’s Eyebrow (a $16 value).

Annie’s Eyebrow transforms unruly facial caterpillars into sleek sinusoids using the ancient art of brow threading. Nimbly wielding strands of twisted cotton fibers, the eponymous Annie and her team of follicular engineers roll over riotous brow gardens, carefully weeding wayward sprouts, shaping topiary arches, and dispatching disoriented acupuncture needles. A gentler and simpler alternative to plucking or chemical-laced depilatory products, threading can be particularly well suited for sensitive skin and tweezer-shy eyeballs.
