You did the hard part. The number on the scale is closer to where you wanted it. But the skin may not have followed.
If you have loose skin after substantial weight loss with semaglutide or tirzepatide, you are not alone. Patients taking medications such as Ozempic, Wegovy, Mounjaro or Zepbound may notice folds at the waist, loose upper arms, changes in the breasts and thighs, or a face that looks less full.
At BellaNova Cosmetic Surgery in West Palm Beach, I start by identifying what has changed: remaining fat, skin laxity, true excess skin, lost volume or deeper structural support. Selected patients may benefit from liposuction with Renuvion. Substantial hanging skin usually requires removal, and some patients need more time before either option makes sense.
I have been performing body contouring after weight loss for 25 years. What follows is what I discuss in consultation: what may improve on its own, where technology can help, and when surgery offers a more realistic answer.
Why loose skin becomes more noticeable after weight loss
Skin stretches to accommodate a larger body. After weight loss, it may not contract enough to fit the smaller shape beneath it. Age, genetics, sun exposure, smoking history, the amount of weight lost and how long the skin was stretched all influence that response.
This can happen after weight loss through medication, lifestyle changes or bariatric surgery. It is not unique to GLP-1 treatment, and taking a particular medication does not determine whether you will need skin removal.
Substantial weight loss can also reduce lean tissue as well as fat. Lean mass measurements include more than muscle, so those terms should not be used interchangeably. Adequate nutrition and appropriate resistance exercise matter when planning weight loss and later body contouring. Look and colleagues on body composition in the SURMOUNT-1 trial.
Will the skin tighten on its own
Some skin retraction may occur as your weight settles, particularly after smaller losses and in skin with better elasticity. The degree and timing vary. There is no reliable deadline after which every patient’s remaining looseness should be called permanent.
Strength training can improve the muscle beneath the skin, and skin care can improve its surface. Neither reliably removes a large fold of excess skin. Noninvasive treatments may provide modest improvement in selected patients, but they generally cannot reproduce the effect of surgical skin removal.
The useful distinction is between laxity and excess. Laxity describes tissue that has become less firm. Excess describes more skin than the underlying body can comfortably support. The two often coexist, and the treatment needs to match both.
My weight stability rule before surgery
I want to see at least three months of stable weight before considering post-weight-loss contouring. That is a minimum in my practice, not an automatic green light. A longer period may be appropriate after major weight loss, for particular operations or when nutrition and medical conditions still need attention.
Just as importantly, I want you living in what I call your “happy place”: a weight you can maintain while eating adequately, enjoying ordinary life and following a sustainable exercise and medication plan. If maintaining the number requires persistent hunger or extreme restriction, we need to address that first.
Continued weight loss may leave new looseness after contouring. Significant regain can stretch the result. If your dose is still changing or you expect to lose more weight, we discuss whether it is better to wait.
Managing GLP-1 medication around surgery
GLP-1 medications can delay stomach emptying, which matters during general anesthesia or deep sedation. Current multisociety guidance allows many patients to continue treatment. Patients with higher risk, including significant digestive symptoms or recent dose escalation, may need additional precautions or a delay. American Society of Anesthesiologists guidance for patients taking GLP-1 medication.
At BellaNova, my usual protocol is to hold weekly injections for two weeks before surgery. Depending on healing and food intake, I may also delay restarting for two to four weeks afterward. This is my practice protocol, not a universal requirement. The final plan must be coordinated with the anesthesia team and the prescribing clinician, particularly if you have diabetes.
Do not stop, restart or change your dose based on this article. You will receive instructions for your own operation, including fasting and medication management.
Where Renuvion and the AYON system fit
Renuvion is a tool I use for selected patients with skin laxity. It is a minimally invasive surgical treatment performed beneath the skin through small incisions, with recovery and risks that need to be discussed.
How Renuvion works
Renuvion combines radiofrequency energy and helium to create plasma. A slender instrument delivers energy beneath the skin to heat and contract collagen-rich soft tissue, including the fibrous bands that help support the skin. When combined with liposuction, it can often use the same access incisions. Those incisions can still leave scars. Ruff and colleagues on Renuvion for the neck and under the chin.
The FDA has cleared the Renuvion APR handpiece for specific uses, including treatment of loose skin in the neck and under the chin, and coagulation of subcutaneous soft tissue after liposuction for aesthetic body contouring. Clearance applies to the specified device and use; it does not guarantee a particular result. FDA Renuvion safety update and cleared uses.
The AYON platform at BellaNova
At BellaNova, I use Renuvion as part of the AYON Body Contouring System. AYON received initial FDA clearance in May 2025 and brings several body contouring functions into one platform, including ultrasound-assisted liposuction, aspiration and Renuvion tissue treatment. I select the components that suit the patient and the planned operation. Apyx Medical announcement of AYON clearance in May 2025.
I have used Renuvion for more than two years. Having it within the AYON platform lets me plan fat removal and tissue contraction together, while keeping the patient’s anatomy and goals at the center of the decision.
When I consider Renuvion
I may consider it for selected patients with mild to moderate laxity, often after liposuction of the abdomen, flanks, upper arms or thighs, or when treating the neck and the area beneath the chin. The decision depends on tissue quality, remaining fat, the degree of excess and the outcome the patient expects.
It may also be considered in selected areas as part of a broader contouring plan. Combining treatments is a surgical decision; it does not mean every area should receive the same technology.
When skin removal is the better answer
A hanging abdominal apron, substantial upper-arm excess or large folds of thigh skin generally require an operation that removes skin. Renuvion cannot repair abdominal muscle separation, restore lost breast volume or reliably remove a large overhang. I explain those limits before recommending it.
For the right patient, Renuvion may improve contour while avoiding the longer incision needed for skin removal. For a patient who needs excision, the longer scar may be the trade-off that produces the more meaningful change.
Risks and recovery
Bruising, swelling, soreness and temporary changes in sensation may occur. Risks include thermal injury, infection, scarring, nerve effects and gas-related complications. I discuss the risks of Renuvion and any accompanying liposuction or surgery as part of the individual plan. Ruff and colleagues on Renuvion for the neck and under the chin.
Recovery depends on the areas treated and the procedures combined. Compression, activity restrictions and follow-up are individualized. Contour is assessed over the following months as swelling settles; a short incision does not mean there is no downtime.
Matching the operation to the body area
After substantial weight loss, more than one area may need attention. I start with the change that bothers you most and examine how treating it will affect the surrounding contour.
Abdomen and pubic area
An abdominoplasty, or tummy tuck, removes excess abdominal skin and can tighten the connective tissue over separated abdominal muscles when needed. The amount and distribution of excess determine the incision. More extensive looseness around the sides and back may call for an extended procedure or a lower body lift. American Society of Plastic Surgeons on body contouring after weight loss.
Upper arms
A brachioplasty, or arm lift, removes loose upper-arm skin. The scar may extend from the armpit toward the elbow, depending on the correction needed. I show patients where it is expected to sit so they can weigh that scar against the excess skin.
Breasts
A breast lift reshapes and repositions the breast after weight loss. An implant may be considered when additional volume is desired. Fat transfer can be an option for selected patients seeking a more modest volume change.
Thighs
A thigh lift removes excess skin using an incision in the groin crease, sometimes with a vertical extension for more extensive looseness. Selected patients with less excess may be considered for liposuction with tissue contraction instead.
Chest in men
The examination distinguishes remaining fat, glandular tissue and excess skin. Treatment may involve liposuction, gland removal, skin removal or a combination. Removing fat alone may leave the loose skin more noticeable.
Facial changes sometimes called Ozempic face
“Ozempic face” is a popular description, not a separate diagnosis. Significant weight loss by any method can make facial hollowing, folds and laxity more noticeable. The plan depends on how much comes from lost volume, tissue descent, skin quality and underlying skeletal support.
My 4D Facelift approach considers the skeleton, muscle and deeper support, skin, and surface. Depending on the examination, treatment may include repositioning deeper tissue, addressing skin excess, restoring selected volume or treating the surface. Skeletal augmentation is considered only when the underlying proportions warrant it.
Filler or fat transfer may help selected volume deficits, but adding volume alone cannot reliably correct substantial tissue descent. Stable weight matters here too, because continuing weight change can alter the result.
Combining and staging procedures safely
Patients understandably want fewer operations and fewer recovery periods. I weigh that preference against operative time, the extent of surgery, blood loss, clot risk, overall health and the support available at home.
A staged plan might begin with the abdomen and adjacent contouring, followed later by the arms, breasts or thighs. Facial surgery may be planned separately. The sequence and interval depend on your priorities and recovery; there is no single schedule that fits everyone.
Combining selected procedures can reduce duplicated costs, but that advantage does not justify an operation that is too extensive. We discuss the plan and its limits before scheduling.
Preparing to heal after weight loss
A smaller appetite can make it difficult to meet protein and calorie needs. Restrictive eating, pre-existing deficiencies or a history of bariatric surgery may create additional concerns. I assess these before operating rather than assuming every patient taking a GLP-1 medication has the same nutritional problems.
My preoperative assessment includes a complete blood count, iron studies, vitamin D and vitamin B12, with hemoglobin A1c when diabetes or another indication warrants it. I also review albumin and prealbumin in clinical context. These blood proteins are affected by inflammation and are not stand-alone measures of nutritional status. ASPEN position paper on albumin and prealbumin.
We address relevant deficiencies and plan adequate food and protein intake before surgery. Medical conditions, hydration, activity and practical help during recovery are part of that preparation.
BellaNova requires patients to avoid nicotine, including vaping and nicotine replacement products, for the specified period before surgery and during healing. We test for nicotine on the day of surgery, and a positive result leads to postponement. Discuss a cessation plan with us early; the interval is part of your individual instructions. American Society of Plastic Surgeons on nicotine and surgical healing.
When I recommend waiting
- Weight is still changing or the maintenance plan is not sustainable.
- The required period of weight stability has not been reached.
- Nutrition, anemia or another medical issue needs attention.
- Nicotine requirements have not been met.
- Diabetes, blood pressure or another condition is not adequately controlled.
- The expected result does not match what the proposed procedure can achieve.
Waiting gives us time to prepare. It does not necessarily mean that surgery will never be appropriate.
Frequently asked questions
Can Renuvion replace a tummy tuck
It may be an option for selected patients with limited laxity, but it does not remove a large skin overhang or repair separated abdominal muscles. The examination determines which problem needs treatment.
How long should I wait after reaching my goal weight
I use at least three months of stable weight as a starting point. Some procedures and patients require longer. Nutrition, medical conditions and the sustainability of your weight matter as much as the calendar.
Do I need to stop Ozempic or Mounjaro before surgery
Follow the written plan from your surgeon, anesthesia team and prescribing clinician. Many patients can continue under current guidance, while BellaNova’s usual protocol may require a pause. Do not change treatment independently.
Will exercise get rid of hanging skin
Exercise can improve strength and the underlying shape. It does not remove substantial redundant skin, although better muscle tone may improve how an area looks.
Does BellaNova accept insurance for skin removal
BellaNova provides elective cosmetic surgery on a self-pay basis. We do not accept insurance or file insurance claims for patients. We provide a written quote and can discuss financing options.
Can I have face and body surgery together
Sometimes selected procedures can be combined, but a broader face-and-body plan often needs separate stages. The extent of surgery and your individual risk determine the recommendation.
What happens if I regain weight
Significant weight changes can alter the contour and stretch remaining skin. Modest fluctuations do not necessarily undo the result, but maintaining a sustainable weight helps preserve it.
