A planar reflector is supported on a ball-and-socket joint and can be independently pivoted about X and Y axes by magnetic drives that propel corresponding bail arms hingedly connected to the reflector. These methods and compositions utilize the hypodermis-targeted release from bioadhesive oral films, pastes or patches applied to oral mucosa or teeth for the purpose of improving the appearance or health of the lips and facial skin. The long gauge bit 20 powered by the motor 10 may have a bit face 22 with cutters 28 thereon and a gauge section 24 having a uniform diameter cylindrical surface 26. Further, a chamber in communication with the movable blade may be pressurized by way of a downhole turbine or pump.
