Renuvion/J-Plasma Skin Tightening

Excess skin can be a troubling issue for many people whether from weight loss, having children, or just bad genetics. Not every person wants to have skin excised or removed, often resulting in long incisions and scars. Renuvion uses a technology called helium plasma which is able to heat and tighten loose skin through a minimally invasive stand-alone procedure or in combination which other procedures. The most common areas for skin tightening are the neck, abdomen, arms, back, flanks, and inner thighs.

How it Works

Renuvion is a unique combination of radiofrequency (RF) and helium plasma energy.  These two forms of energy act to quickly heat tissues to a specific target temperature which promotes tissue contraction. This increase in heat happens almost instantaneously minimizing risks of tissue damage and burns. The cycle of tissue heating and cooling occurs in under a second! The heat produced by Renuvion causes collagen denaturation (breakdown) resulting in the body making new collagen and subsequent skin tightening. Because this is a minimally invasive procedure, it can be performed under both local and general anesthesia.

Renuvion/J-Plasma Improvements

 Renuvion works well in all parts of the body with loose skin. This procedure will result in:

  • A 30% tightening of skin in the areas treated

Renuvion/J-Plasma Technique

 Renuvion can be performed either under local or general anesthesia depending on the size of the treatment areas and patient desires.


The procedure begins by making multiple small (2-3mm) incisions in concealed areas of the body. A saline solution containing lidocaine and epinephrine is then infiltrated into the areas to be treated. This is to help prevent bleeding and helps with post-operative pain control. Small tunnels are then made beneath the skin with a fine cannula. Renuvion is then used to heat up the underlying fibroseptal network resulting in firmer, tighter skin. After surgery, light compression worn over the treatment areas to help reduce post-procedural swelling.

During your pre-operative visits, Dr. Sieber will work with you to determine exactly which body areas you want treated and whether or not you are a good candidate for this procedure.

Preparing for Renuvion/J-Plasma

 As with any major surgery, all medications and supplements which cause an increased risk of bleeding should be stopped 2 weeks prior to surgery. Please see our list of medications and supplements to avoid. As always, make sure to check with your doctor before stopping any medications.

Recovery from Renuvion/J-Plasma

Recovery from Revuvion can vary some depending on the size and number of areas treated. For small areas such as the neck/jawline, the recovery should be relatively quick. There will be some minor bruising and swelling immediately after the procedure which should will resolve over the next 3-5 days after the procedure. You will be wearing compression immediately after the procedure which will be worn all the time for the first week, then only at night for a total of 2 more weeks. The compression helps to reduce swelling and bruising.

After surgery you will need to refrain from any rigorous activity for the first 2 weeks. Starting activities too soon after surgery may put you at risk for bleeding. You may begin to perform light exercise 2 weeks after your surgery and may gradually increase your activity as you tolerate. Continuing with a healthy diet and active lifestyle after your procedure will help to further enhance your surgical results.

Renuvion/J-Plasma  FAQs

Q: How many Renuvion treatments before I see results?

A: Most body areas only require a single treatment. Patients should see about a 30% tighten of skin in treated areas

Q: How long will it take before I see results?

A: It may take 6-9 months to see your final result. The heat from the Renuvion causes collagen to be broken down and reformed. As the body creates new collagen a gradual tightening will occur in treated areas.

Q: What procedures is Renuvion commonly combined with?

A: Renuvion is most commonly used as an adjunct to liposuction. After fat has been removed through Vaser or traditional liposuction, Renuvion is then used for additional skin tightening.

 Q: Is Renuvion the same thing as J-Plasma

A: Yes! Renuvion and J-Plasma are the same devices which use helium plasma for skin tightening. J-Plasma is the older name of the device which has been updated and rebranded as Renuvion.

Q: Can I have Renuvion if I have already had liposuction?

A: Yes, Renuvion can be performed in patients who have already had liposuction, whether recently or many years ago. In patients who have previsouly undergone liposuction, the healing from Renuvion may be prolonged slightly as there is a propensity to form more scar tissue in the immediate post-operative period.

Q: Is it safe to have Renuvion at the same time as a tummy tuck?

A: It is! Not all patients require a full tummy tuck due to lack of skin excess in the upper abdomen. These patients instead can be treated with a mini-tummy tuck to address skin laxity of the lower abdomen and Renuvion to the upper abdomen for additional skin tightening in this area.

Q: Who is not a good candidate for Renuvion?

A: Patients who have a previous history of forming poor scar tissue after treatments such as liposuction may not be ideal candidates for Renuvion. Additional energy and heat are placed into the skin during the treatment, so patients prone to fibrosis should notify Dr. Sieber of their past surgical experiences.

Q: Can you tell who will respond best to Renuvion?

A: Formation of new collagen can vary widely from patient to patient so some people may experience more robust skin contraction while others may have slightly less. On average, Renuvion produces about a 30% improvement in skin laxity in most patients.


I couldn’t be more pleased and excited about the refresh Dr. Sieber did on my face using a combination of botox and fillers. I had a baby a year ago and my face looked completely deflated. It felt to me that I looked like I had aged 5 years instantly by having a baby over 40. Dr. Sieber looked closely at my face and listened to my desires and fears in terms of the results I was seeking. I really liked that he took a conservative approach and followed up to check in and tweak things once the fillers and I had time to settle in.*

Dr. Sieber is a caring, friendly and talented doctor. I had two long consultations (free of charge) before scheduling my BBL (Brazilian butt lift). The staff and Dr. Sieber made me feel calm and relaxed the day of surgery. The results are amazing. Dr. Sieber understands a woman’s body and totally changed the shape of mine. I could not recommend him highly enough. I now go to him for my Botox and Juvederm.*

Dr. Sieber was fantastic throughout the entire process. From the beginning, he was patient with my questions and never made me feel pressured about making a decision. Once deciding that I was going to move forward with a breast augmentation, he made sure that I understood the process of the procedure and what I could expect post-surgery. I could not be happier with the results!*

Dr. Sieber is the best. I interviewed with numerous doctors. He pays close attention to detail. He called and checked on me and my results on a regular basis. My tummy procedure exceeded my expectation.*

Dr Sieber was very kind, knowledgeable and patient. He was able to answer all of my questions and put me completely at ease during the consultation as well as during the actual procedure. He made sure that I understood each part of the process which went a long way in alleviating my fears…after all, this is my face!*

Dr. Sieber is attentive, responsive, and well trained. I had seen him for Botox and filler and he had done both without any pain or bruising and more importantly the results were fabulous. He has met with me on time at each appointment. He communicates what to expect, made sure I was comfortable throughout the procedure, checked on my healing every day post procedure. He couldn’t be more delightful not more talented. I had seen other plastic surgeons for in office treatments over the past decade and Dr. Sieber is at the top of the list in terms of delivering the desired outcome and high quality care.*
