As guests arrive at SparknShine, professionally trained staffers greet them with a litany of relaxing and beautifying treatments. Massage therapists soak smooth, iron-rich river rocks in warm water before placing them on specific points of the body to ease tense sinews. While detoxifying footbaths are busy nurturing bioelectrical systems and expelling toxins, technicians strengthen fingernails with Bio Sculpture Gel. Their laser arsenal brightens teeth up to seven shades and points unwanted hairs toward the thriving wig industry. When they aren't accentuating eyelids with lash extensions, they buff away acne and fine lines with microdermabrasion treatments.
