Renuvion J-Plasma is an advanced treatment that blends helium plasma with radiofrequency (RF) waveforms to better control tissue manipulation and deliver precise results with minimal trauma. It is an alternative to a neck lift or facelift, which involves incisions around or behind the ear to remove excess skin. Renuvion is performed under local anesthesia, along with a few chill pills in the RefinedMD office.
A neck lift is effective, but invasive and it requires several incisions around the ears to vanquish excess skin. Optimal skin contraction sourced from heat can cause blistering, burns, and even scarring—until now. Thanks to Renuvion J-Plasma, skin can be optimally contracted in less than a second for a safe and very effective result. J-Plasma can be used as an alternative to a facelift and neck lift in some cases, or can even be an alternative to treating this troublesome sagging skin.
Renuvion J-Plasma involves the novel use of cool helium-based plasma technology and radiofrequency (RF) energy to efficiently and safely heat the under-surface of the skin for the optimal contraction of the skin and underlying fibroseptal network in a fraction of a second without the need to monitor the surface skin temperature. Safe, efficient, and efficacious, this technology is revolutionary and one-of-a-kind in terms of its ability to achieve facelift-like skin tightening without the need to cut skin! Furthermore, Renuvion skin tightening can be added to neck liposuction, neck muscle contouring (platysmaplasty), and chin implant procedures to further enhance results in the neck in appropriate patients. Ideal patients are in their 30s to 40s with mild to moderate skin laxity in the neck.
What we like best about Renuvion J-Plasma skin tightening is that results continue to improve over a year because of the remarkable effect of Radiofrequency energy on restoring youthful collagen architecture to the skin and suppleness to the underlying soft tissue.
Partial results can be seen immediately after Renuvion J-Plasma but final outcomes are best appreciated at the 6 week mark and beyond. Improvements can be seen up to 1 year after the procedure.
The results from Renuvion J-Plasma are quite dramatic and long-lasting. However, as with any other cosmetic surgical procedure, the results are not entirely permanent as the effects of aging still occur over time. That being said, procedures such as Renuvion J-plasma will absolutely help to reverse the signs of aging and postpone the aging process.
Most patients experience very little discomfort after surgery. Some bruising, swelling and mild inflammation is experienced for a period of about 7-10 days. Occasionally, a small amount of prolonged swelling in some areas of the neck can occur for several weeks due to the energy delivered by Renuvion to the skin and underlying tissues. A compression garment is typically worn 24/7 for the first three days, then at night (and as much as possible during the day) for the next 5 weeks. This is to ensure optimum results.
Renuvion J-Plasma is a device that uses advanced cool helium plasma technology to effectively and efficiently deliver radiofrequency energy under the skin to create a significant tightening of the skin and underlying tissues in a very precise and safe manner.
Renuvion J-Plasma can be used to tighten the skin in multiple areas around the body. Some of the most common areas to have Renuvion J-Plasma performed are the abdomen, waist, arms, thighs, face, and neck. Although often paired with liposuction, Renuvion J-Plasma can be used by itself to improve skin laxity, offering a non-excisional treatment option for patients who want to minimize surgical recovery. Renuvion may also be used externally on the face for significant skin tightening, resurfacing, and improvements in discoloration and texture.
Dr. Roy performs his Renuvion J-Plasma neck lift procedure under local anesthesia and minimal oral sedation. Patients tolerate numbing of the neck region very well, especially with the combination of using mild oral sedatives and nitrous oxide (ProNox) inhalation. Once the neck is numb, the patient experiences no pain whatsoever during the procedure itself!
Absolutely yes! Renuvion J-Plasma has been proven to be a safe and effective treatment for skin tightening, reducing the risk of skin injury due to its novel delivery system and energy profile.
Patients typically arrive 45 minutes prior to the start of the procedure to pre-medicate and allow for a calming period during which oral sedation kicks in. The patient is then brought to the operating room where the neck is injected with local tumescent anesthesia. This process is rendered very tolerable by the oral sedation provided as well as self-administered nitrous oxide (ProNox) gas.
Once the neck is completely numbed, Dr. Sudeep Roy makes a small 2cm incision under the chin, as well as two tiny incisions under each ear lobule, through which liposuction and platysmal muscular contouring (platysmaplasty) are performed. The Renuvion handpiece is then introduced through the same incisions, and within a matter of a few minutes, the entirety of the skin in the lower face and neck is precisely treated.
The radiofrequency energy delivered through the cool helium plasma immediately tightens the skin, while re-orienting existing collagen fibers in the skin as well as stimulating the production of new collagen in the treated areas. This induces further contraction of the skin that continues for several months after the procedure.
Once the procedure is completed, the incision under the chin is closed with a few sutures and the neck placed in a compression dressing overnight.
After surgery, patients can experience mild discomfort, numbness, bruising, and swelling, as with any surgical procedures involving the neck. This typically resolves in 7 to 14 days. Some prolonged swelling can persist beyond this point due to the very focused radiofrequency energy delivered to the skin with Renuvion.
Since establishing RefinedMD in 2012, Dr. Swengel has earned a reputation throughout the South Bay as one of the area’s top cosmetic and medical dermatologists. He is sought out for his expertise as a Mohs micrographic surgeon and laser treatment specialist, as well as his warm, attentive style of patient care.
