In contrast to laser and intense pulsed light systems that are limited in use in patients with dark skin, RF energies are "color blind" and can be used for patients of all skin types. 12 The latest generation of RF is the United States Food and Drug Administration (FDA)-cleared multisource phase-controlled 3DEEP ™ technology, which uses six independent phase-controlled RF generators. The multiple electrical fields created repel each other and force the energy to flow to a deeper layer of the skin. This innovative technology reduces the amount of energy flow through the skin surface allowing highly effective, painless heating of the dermis and subcutaneous tissue, eliminating the need of active epidermal cooling. 15,16 To prevent overheating, the energy is emitted only if the electrodes are in full contact with the skin and the handpiece is in motion. Real-time measurement of skin impedance assures the delivery of constant energy to the patient skin independent of their skin impedance. 17–19 de la Torre et al 20 studied the use of multisource phase-controlled RF for the treatment of abdominal area lax skin. For the study, the authors used the EndyMed Pro systems with the large, linearly arranged 6 electrodes handpiece (Figure 1A). Patients were treated six times and re-examined at 6, 9, and 12 months after the end of the treatment sessions. Confocal microscopy images showed increase in epidermal thickness, changes in dermal papillae, and dermal collagen matching younger rejuvenated skin. Abdominal circumference measurements have shown an average reduction of 2.9cm after six treatments and 1.9cm 12 months after the end of the sessions. 17 In the present clinical study, the authors used EndyMed's latest multisource RF handpiece, the Shaper, which is specially designed for body skin treatments (Figure 1B), [Abstract continued] t he results and finished all the treatment sessions. Twenty-four patients (96%) saw an improvement in body shape. ninety-two percent of the patients would recommend the treatment to others. overall change graded by the physician by the global aesthetic improvement scale provided the following results: 44 percent of the patients had more than 75-percent improvement, 32 percent of the patients between 50- to 75- percent improvement, 20 percent of the patients had between 25- to 50-percent improvement and only four percent had less than 25- percent improvement. Conclusion: The authors' data show that the handpiece examined provides high eIcacy in skin tightening and body contouring after 5 to 8 painless treatments. Patient subjective questionnaires show very high satisfaction rates. J Clin Aesthet Dermatol. 2017;10(4):24–29. Figure 1A. Multisource RF large handpiece with six linearly arranged electrodes
