Derma Science Spa's licensed therapists help restore youthful radiance to epidermal landscapes with hot-stone massages and European facials. Drawing on ancient healing traditions, the one-hour hot-stone massage enlists the tension-taming might of basaltic stones, rich in heat-retaining iron and polished over the eons by the velvety soft hands of mermen. The rocks radiate warmth into the body at strategic positions, typically along the back but sometimes also between the toes or on the palms of the hands. As muscles relax, sluggish circulation boosts and aches start to slowly recede toward their retirement homes in Northeast Ohio.

The European facial uses Atzen products from France, a line of skin-softening potions blending pharmaceutical-grade and organic ingredients loaded with vitamins, minerals, and reparative peptides. After an initial skin analysis, a cleansing, steaming, exfoliation, and sequence of extractions purge impurities and banana-cream pie from the face, neckline, and décolleté. A massage plunges freshly cleansed bodies further into relaxation as a treatment mask goes to work, tailored to each patient's skin type. The approximately 45-minute facial helps facades combat blemishes, lock in moisture, and maintain soft, healthy-looking skin.
