Studies show that modulating one's facial expression instantly builds camaraderie, whether by laughing at a joke, frowning at a sad story, or making empathetic fish lips at an unemployed merman. Prep your kisser for many roles with today's Groupon: for $95, you get three European facials at Renee Day Spa (up to a $195 value).

The experienced aestheticians at Renee Day Spa polish skin and whisk away worldly cares with a slew of luxurious spa services. The half-hour European facials begin with a surface cleansing, washing away grime, makeup, and temporary mustache tattoos left over from railroad-tycoon sting operations. Extraction unclogs pores and does away with pimples and blackheads before an exfoliation scours away dead epidermal cells, letting youthful skin shine through. A soothing mask finishes off the facial, infusing skin-nourishing emollients deep into the skin and relaxing faces left achy from face-making contests with magic mirrors.

Though Renee Day Spa sometimes features a discounted price online, this Groupon still offers the best deal available.
