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 $30, you get a diamond-tip microdermabrasion treatment at Relax Massage & Facial Studio (a $60 value).

At Relax Massage & Facial Studio, highly trained aesthetician Melissa brandishes a diamond-tip wand over the face and neck to smooth away dead skin cells during a one-hour microdermabrasion session. First, Melissa cleanses visages before steam rolls over pores, preparing them for extractions and cold-therapy treatments, depending on individual needs and any past traumatic experiences with snowmen. Melissa then blasts away dead epidermal layers with the diamond-tip wand to diminish lines, dark spots, and the imprints of blemishes past. She intersperses these treatments with gentle neck, hand, foot, and face massages, and finishes the session by painting a custom mask onto skin and dabbing on toner and a dollop of moisturizer to make façades glow as much as a pregnant jack-o’-lantern.

Though Relax Massage & Facial Studio sometimes features a discounted price online, this Groupon still offers the best deal available.
