![]() ![]() “Patients also describe it as a natural-looking result-youthful is a term they keep using.”Īccording to the manufacturer, ePrime treatments result in a unique healing process that demonstrates neo-collagenesis and neo-elastogenesis, which has been well-documented in scientific studies. Unlike other technologies that only claim to produce results at 5 or 6 months after treatment, Chasin’s patients are noticing tightening of the skin, toning of their skin, and a healthier and more youthful appearance, “and that starts to develop right around the fourth or fifth week and continues for several months,” he says. This approach translates into more control for the physician, he adds, and that is “much more accurate and much more safe.” With other technologies, the end point is either what the patient feels, which may be pain, or it may be some redness on the surface of the skin-or it may no end point at all.” Our end point here is the knowledge of the exact temperature inside the tissue. “We are able to know exactly how much heat and how much damage we’re creating. “It’s really the first time we have been able to deliver the energy at the exact depth we want, by putting the needle into the exact layer of the skin,” Chasin says. Chasin considers the device a new volumizing technology that improves skin tone by increasing collagen and elastin production in the skin, with the benefit of toning the skin with minimal downtime. To get a better understanding of how the ePrime works, PSP spoke with Mitchell Chasin, MD, medical director at the Reflections Center for Skin and Body in Livingston and Bridgewater, NJ. As the needles deliver the energy under the skin, sensors within the electrode tips continually measure tissue temperature and impedance during treatment for optimal treatment control and effectiveness. ![]() The handpiece generates energy of 70☌ for 4 seconds. Each time the practitioner pulses the device, the needles penetrate the skin to deliver a prescribed amount of energy. The form factor of the device’s handpiece is wand-like and uses an array of 10 32-guage needles that provide fractionated delivery of energy to the deep dermis. ePrime uses a microneedle electrode array that delivers bipolar RF energy for skin-tightening procedures. This principle has been ported use with the delivery of heat to the skin for aesthetic treatments. Microneedle-based products, which can be found in use in many medical specialties, are typically the basis for drug-delivery techniques that administer medications through the skin without causing pain. This radiofrequency (RF)-based energy device uses “microneedling” to treat lax skin, and offers distinct differences when compared with other technologies in the field. Whereas many new energy-based products in the aesthetic field tend to be adjuncts or upgrades to existing, well-established product lines, ePrime (from Syneron Candela, Irvine, Calif) is an actual unique addition. ![]() Fractionated zones of thermal injury are created in and limited to 1 mm to 2 mm into the deep dermis. Comparing ePrime with other energy-based delivery systems. ![]()
