Claim:
1. A device suitable for treatment of a volume of hypodermis with energy through a skin surface, the device comprising: a sonotrode having an acoustic radiative surface and an ultrasound transducer functionally associated with the sonotrode, said ultrasound transducer configured, when activated, to generate acoustic waves that are directed by said acoustic radiative surface into the volume of hypodermis for conveying an effective amount of acoustic energy into the volume of hypodermis for aesthetic modification thereof; and an RF energy source and an RF applicator having an RF radiative surface, said RF applicator functionally associable with the RF energy source, said RF applicator being configured to direct RF waves generated by an activated RF energy source to said RF radiative surface to form a unipolar RF field for depositing an effective amount of thermal energy in the volume of hypodermis for aesthetic modification thereof, wherein the device is configured for activation of said ultrasound transducer and said RF energy source independently or concurrently; said sonotrode and said RF applicator are the same component whereby the acoustic radiative surface and the RF radiative surface are coupled to the same portion of the skin surface; and the radiative surface common to the sonotrode and the RF applicator comprises a layer of dielectric material configured to serve as an insulator to prevent conduction of current through the RF radiative surface when coupled to an active RF energy source and as an acoustic matching layer when coupled to an active ultrasound transducer.
