In a massage room awash in shades of plum, one of Serenity Spa Wellness Center's licensed therapists plunges deft fingers into muscular structures to weed out pesky pain points and break up congregations of tension. Increasingly relaxed breaths drift out of the private room, past cedar-colored planks, and toward the far-infrared sauna, which uses dry heat in an effort to draw toxins from the body or elicit confessions from ice-cream smugglers. Aestheticians blend ingredients for facial treatments and combine fragrant swirls of essential oils, catering to individual skin and health issues. In the reception area, hands warm around mugs from a coffee bar, and floral-patterned or zebra-print chairs cradle guests.
