For men who have dedicated hours to the gym or achieved significant weight loss, stubborn, loose skin can often obscure hard-earned muscle definition.
Traditional skin excision surgeries require additional planning and downtime, while non-invasive treatments sometimes fall short of expectations. Renuvion® Skin Tightening bridges this gap perfectly. By combining cold helium plasma with radiofrequency (RF) energy, this groundbreaking, minimally invasive procedure tightens the subdermal tissue matrix from the inside out. Renuvion can be done as a standalone treatment or as part of a more comprehensive skin-tightening surgical plan.
At North Florida Plastic Surgery, board-certified Gainesville plastic surgeon Dr. David Mateo develops personalized Renuvion treatment plans that focus on proportion, symmetry, and realistic results. By combining advanced surgical techniques with careful planning, the team helps patients achieve a stronger definition and a more confident appearance.
Procedure Purpose: Subdermal tissue coagulation to instantly tighten loose or sagging skin.
Target Areas: Abdomen, flanks ("love handles"), chest, neck, and jawline.
Average Duration: 1 to 2 hours, depending on the number of treated areas.
Typical Downtime: 2 to 5 days for a desk job; 2 to 3 weeks before resuming strenuous workouts.
Renuvion (formerly known as J-Plasma) is a cutting-edge, minimally invasive body contouring treatment designed to snap loose skin back into place.
Unlike external lasers, Renuvion operates beneath the skin's surface. Dr. Mateo inserts a specialized, slender probe through tiny, strategically placed incisions. The device emits cold helium plasma simultaneously with RF energy to rapidly heat the collagen fibers to the precise temperature required for maximum contraction, while the helium gas instantly cools the area to protect surrounding tissues.
For men, this means an unparalleled ability to shrink-wrap skin over muscle structures, making it an excellent standalone option or a powerful complement to male liposuction.


On the day of your procedure at North Florida Plastic Surgery, you will be made completely comfortable using either oral sedation or general anesthesia, depending on the scope of your treatment plan.
Once the anesthesia takes effect, Dr. Mateo creates minor, freckle-sized incisions near the targeted areas. If you are combining Renuvion with liposuction, the same incisions are utilized. Dr. Mateo gently passes the Renuvion handpiece under the skin. As the energy is activated, you may hear a soft buzzing sound, but you will feel no pain. The dual-action energy immediately contracts the fibrous bands holding your skin to the underlying muscle. The entire process takes just 30 to 60 minutes per zone, after which the micro-incisions are closed, and a supportive compression garment is applied.


Renuvion is highly versatile and can treat almost any area of the body suffering from skin laxity. For male patients, it is most frequently used to define or “etch” abdominal muscles, sculpt the flanks, firm the chest (pseudo-gynecomastia), and sharpen the neck and jawline.
Choosing Renuvion allows male patients to achieve surgical-level skin tightening without the corresponding scars or lengthy downtime.
Because the device is inserted through micro-incisions, there are no long, conspicuous surgical scars left behind. Your results look entirely natural, highlighting your muscle memory and frame rather than signs of a surgical intervention.
When men undergo liposuction to remove stubborn fat pockets, the remaining skin can sometimes look loose or wavy. Renuvion serves as the ultimate finishing touch, contracting the empty space so the skin hugs the newly sculpted muscle layers beneath.
Unlike non-invasive external treatments that require a matrix of multiple sessions over several months to show mild improvements, Renuvion delivers dramatic, structural tightening in just a single outpatient treatment.

The ideal candidate for Renuvion is a man in good overall health who is at or near his goal weight but struggles with mild-to-moderate skin laxity.
Who it is for: Men looking for a sharper jawline, flatter abdomen, or tighter chest contours without undergoing an invasive lift surgery.
Who should avoid it: Patients with severe, hanging skin folds (who may be better suited for an excisional surgery like a tummy tuck) or those with unmanaged medical conditions that could impair healing.
During your consultation, Dr. Mateo will physically assess your skin elasticity to ensure Renuvion is the right match for your anatomy.
Recovery from Renuvion is highly manageable, especially compared to traditional open surgeries. Most men experience mild soreness, swelling, and bruising in the treated areas, which peaks within the first 48 hours and can be easily managed with prescribed or over-the-counter pain medication.
You will need to wear a form-fitting compression garment underneath your clothes for eight weeks. This garment keeps swelling to a minimum and supports your tissues as they heal into their new, tightened positions. Most patients can comfortably return to a desk job within 3 to 5 days. Dr. Mateo advises refraining from heavy lifting, strenuous gym workouts, and steam rooms for approximately 3 weeks to ensure optimal subdermal healing.


One of the most satisfying aspects of Renuvion is that some of the results are visible immediately. As the collagen fibers contract under the skin during the procedure, you will notice an instant tightening effect as soon as your initial post-op swelling begins to recede.
However, the true transformation unfolds over the following 3 to 6 months. The internal thermal energy triggers a robust process of neocollagenesis: the production of brand-new, healthy collagen and elastin fibers. As this new structural matrix matures, your skin will continue to firm up, revealing a stronger, more sculpted definition. Because Renuvion fundamentally alters and rejuvenates the subdermal tissue, the results are long-lasting. While it cannot stop the natural aging process completely, it effectively resets the clock on your skin laxity for years to come.
Achieving a natural, powerful masculine contour requires a delicate balance of surgical expertise and artistic vision. Dr. David Mateo is a board-certified plastic surgeon who understands that male aesthetics rely heavily on maintaining proper bodily proportions and sharp, clean lines. He does not believe in a one-size-fits-all approach. By combining the state-of-the-art physics of Renuvion with personalized surgical planning, Dr. Mateo and his dedicated team ensure that your treatment preserves your unique anatomy while providing a noticeably firmer, more athletic, and confident appearance.

Because the procedure is performed under sedation or anesthesia, you will not feel any pain or discomfort during the treatment itself. In the days following the procedure, you will feel a sensation similar to muscle soreness after an intense workout. This is normal and easily managed with standard recovery protocols.
Yes, absolutely. For men experiencing pseudo-gynecomastia (excess fatty tissue and loose skin in the chest area), Dr. Mateo frequently pairs liposuction with Renuvion. Liposuction removes the fat cells, while Renuvion tightens the chest skin to prevent sagging, creating a flatter, more masculine chest profile.
The incisions required for the Renuvion probe are exceptionally small—typically only a few millimeters wide. Dr. Mateo expertly places them within natural skin creases or areas easily hidden by swimwear or underwear. Once fully healed, these marks generally fade into tiny blemishes that are barely noticeable.
Unlike non-surgical alternatives that rely on repeated treatments over time, Renuvion is a "one-and-done" procedure. You only need a single session to achieve significant, long-lasting skin tightening results.
The structural tightening accomplished by Renuvion is essentially permanent because it changes the sub-surface tissue composition. However, your skin will still be subject to the future natural effects of gravity and aging. Maintaining a stable weight and a healthy lifestyle will help preserve your sculpted results for many years.
