As you get older, you may notice sagging or crepey skin in certain areas of your face, neck, and body. Skin laxity on your upper arms or neck can make you self-conscious in certain clothing or social situations. If you are not ready for a surgical procedure to improve loose or sagging skin, Renuvion skin tightening, also known as J-Plasma®, is an effective option.
How Does Renuvion Work?
Renuvion is a skin-tightening treatment that uses radiofrequency (RF) energy in combination with helium gas to improve sagging, loose skin. During the treatment, a thin wand is inserted just under the skin, delivering a stream of helium plasma and RF heat directly to the tissue.
These energy streams cause the collagen fibers beneath the skin to contract, resulting in tighter and firmer surface skin. Renuvion also spurs the body’s healing process, prompting the longer-term production of collagen (neocollagenesis) for even firmer skin. The treatment is typically performed as an outpatient procedure and takes around 30 to 45 minutes to complete.
Which Areas Can I Improve With Renuvion?
Some commonly treated areas include:
- Lower face
- Upper arms
- Buttocks
- Thighs
- Neck
- Jowls
You can easily combine Renuvion with body sculpting treatments such as liposuction. Liposuction reduces stubborn fat deposits on your body but can’t tighten the surface skin. When combined with body sculpting procedures, Renuvion can enhance your results.
What Can I Expect During the Recovery Process?
After the procedure, there is often mild to moderate swelling, bruising, and discomfort. Many patients can return to light activities in a few days. However, recovery is longer for more extensive treatments, such as larger treatment areas or when Renuvion is combined with liposuction.
Because tissue contraction continues over weeks to months, the final results are not immediate. Some tissue tightness improves over 3 to 6 months. Post-operative care (compression garments, avoiding strenuous activity, following your surgeon’s instructions) is crucial for minimizing risks such as fluid accumulation, swelling, and skin irregularities.
How Soon Will I See Results After Renuvion?
You will see tighter, firmer skin immediately after the procedure, although your skin will keep improving for several months to come. However, bruising and swelling may obscure some of your results after the treatment. It takes 6 to 9 months for your skin’s neocollagenesis phase to build firmer, tighter, smoother skin.
How Long Does Renuvion Last?
While individual results vary, data and clinical experience suggest that Renuvion’s improvements continue to evolve and may last for several years. Some initial tightening is usually visible right away, followed by continued tissue improvement (collagen remodeling, skin contraction) over 3 to 6 months. One study found that combining Renuvion with liposuction showed results lasting beyond that timeframe, depending on the patient’s age, skin quality, lifestyle, and how mild vs. severe the laxity was.
Are You a Good Candidate for Renuvion?
You are a good candidate for this procedure if you have mild to moderate skin laxity and prefer a nonsurgical treatment. You must be in good health and have realistic expectations about your results. Patients who want to improve severe skin laxity due to weight fluctuations or pregnancy may have better results with a surgical procedure such as a facelift or tummy tuck.
Renuvion improves sagging and inelastic skin with minimal recovery and downtime. To see if you are a good candidate for this treatment, request a consultation or call us at (239) 262-5662 to schedule an appointment.
