Aside from wearing boldly lettered sandwich boards, the human body communicates most clearly and efficiently through its feelers and its eyebrows. Today's Groupon gives eyebrows the customization they seek: for $10, you get eyebrow threading at Threading Diva (a $20 value).

Brow sculptors at Threading Diva whisk unwanted whiskers away, sculpting perfect brows without disturbing sensitive skin. Threading, a gentle depilatory method used by ancient Egyptians to remove fuzz from hair-obscured hieroglyphics, shapes eye arches into expressive works of art by rolling twisted thread across brow bristles to pluck out hair by the roots. Whereas fragrances and chemicals associated with other hair-removal methods can irritate sensitive skin, threading removes even the finest facial hair without worry of interacting with sensitizing medications, conditions such as rosacea, or tattoos of sewing needles. In about 10 minutes, professionals transform ragged eye roofs into elegant trellises that enhance eye contact with wordless expression.
