Even with the most superficial, 1.5mm deep transducer, the ultherapy's energy may be delivered too deeply for the hand. If you are trying to build up collagen, then Fraxel Restore is an excellent therapy for the tops of the hands. Several treatments would have to be done. Fillers such as Restylane, Radiesse and Fat injections have been used, off-label, to build up volume which is often needed in the aged hand to help hide the bulging veins.
