Losing weight can leave you with loose skin around your abdomen, arms or thighs, even after reaching your target weight. You may wonder whether Exilis Ultra 360 could help improve your skin firmness without surgery.
Exilis Ultra 360 combines radiofrequency and ultrasound to heat the tissue beneath your skin and encourage collagen remodelling. It may offer modest tightening, but if you have significant excess skin after major weight loss, you may need to consider surgical options.
Why Does Your Skin Become Loose After Weight Loss?
Your skin contains collagen and elastin, which help it stretch and stay firm. When you lose weight, the volume beneath your skin decreases, but your skin may not shrink enough to match your new body shape.
How much loose skin you develop depends on your age, genetics, previous body size and how much weight you’ve lost. You may notice some areas tighten naturally, while others remain loose despite maintaining your weight.
How Does Exilis Ultra 360 Work on Loose Skin?
Exilis Ultra 360 combines radiofrequency and ultrasound to deliver controlled heat beneath your skin. This may encourage collagen remodelling and gradually improve your skin’s firmness and smoothness.
During treatment, your practitioner moves an applicator over your chosen area while monitoring the temperature and your comfort. Unlike surgery, Exilis Ultra 360 doesn’t remove excess skin, so results may be limited if you have significant loose skin after weight loss.
Can Exilis Ultra 360 Really Tighten Skin After Weight Loss?
Exilis Ultra 360 may help improve mild loose skin after weight loss, particularly if your skin still has some elasticity. You may notice slightly firmer, smoother skin, but the results are usually modest.
If you have deep folds or significant hanging skin, Exilis Ultra 360 is unlikely to remove them. Your practitioner can assess your skin and help you decide whether treatment is suitable.
Evidence Note
A 2017 study published in the Journal of Cosmetic Dermatology assessed 34 participants receiving four weekly treatments using combined radiofrequency and ultrasound technology. Ten participants were treated for facial skin laxity, while the remaining groups received treatment primarily for fat deposits on the arms, thighs or abdomen.
Although researchers reported improvements in appearance and patient satisfaction, the study did not specifically evaluate substantial loose skin after major weight loss. It also lacked an untreated comparison group and assessed treatment photographs at three months. These findings provide preliminary support for selected cosmetic applications but cannot establish how much hanging skin Exilis Ultra 360 can tighten or how long improvements will last.
Who Is Most Likely to Benefit From Exilis Ultra 360 After Weight Loss?
You may benefit from Exilis Ultra 360 if you have mild loose skin around your abdomen or upper arms and want a subtle improvement without surgery. Your skin’s elasticity and overall condition can influence your results.
You should also have realistic expectations, as you may need several sessions and results can vary. Your practitioner can assess your skin and medical history before recommending treatment.
Can Exilis Ultra 360 Tighten Loose Abdominal Skin After Weight Loss?
If you’ve lost weight and have mild loose skin around your abdomen, Exilis Ultra 360 may help improve firmness and smoothness. However, it won’t remove large folds of hanging skin.
Your concern may also involve remaining fat rather than loose skin alone. Your practitioner can assess your abdomen and recommend whether skin tightening or surgery is more suitable.
Can Exilis Ultra 360 Improve Loose Skin on Your Upper Arms?
Exilis Ultra 360 may help improve firmness if you have mild loose skin on your upper arms after weight loss. Your results will depend on your skin quality and the amount of excess tissue.
1. Mild laxity: Treatment may offer a subtle improvement in skin firmness.
2. Skin quality: Better elasticity may influence how your skin responds.
3. Significant loose skin: Hanging skin is unlikely to tighten sufficiently with non-surgical treatment.
4. Surgical option: An arm lift may be more suitable if you have substantial excess skin.
Your practitioner can assess your arms and explain what level of improvement is realistic for you.
Can Exilis Ultra 360 Help Loose Skin on Your Thighs, Hips and Other Areas?
If you’ve lost weight and have mild loose skin around your thighs or hips, Exilis Ultra 360 may help improve firmness. Your results will depend on your skin quality and the amount of excess skin in each area.
If you have deep folds or skin that rubs when you walk, non-surgical tightening may not be enough. Your practitioner can assess your concerns and explain whether Exilis Ultra 360 or a surgical option is more suitable.
When Should You Seek Medical Advice About Loose Skin Folds?
If your skin folds repeatedly become sore, inflamed, cracked or infected, you may need medical assessment rather than cosmetic tightening. Persistent rashes, bleeding, discharge or difficulty keeping the area clean should be discussed with your GP.
Exilis Ultra 360 cannot remove the excess skin responsible for these problems. Your clinician can help you consider appropriate treatment, including surgery when necessary.
Exilis Ultra 360 After Weight Loss: What Results Are Realistic?
| Skin Concern | Potential Role of Exilis Ultra 360 | Important Limitation |
| Mildly loose or crepey skin | May offer subtle improvement in firmness | Results are variable and not guaranteed |
| Mild abdominal skin laxity | May be considered after assessment | Evidence specific to post-weight-loss skin is limited |
| Mild upper-arm laxity | May offer modest cosmetic improvement | Research has not established predictable removal of hanging skin |
| Mild thigh laxity | May be considered in selected cases | Body-contouring measurements are not proof of skin removal |
| Significant hanging skin | Unlikely to provide sufficient correction | Surgical removal may be more appropriate |
| Skin folds causing recurrent irritation | Not a treatment for the underlying excess skin or infection | Medical assessment and possibly surgery may be needed |
How Does the Amount of Loose Skin Affect Your Treatment Results?
The amount of loose skin you have can influence how well Exilis Ultra 360 works. If you have mild laxity or slightly wrinkled skin, you may notice modest improvements, but significant hanging skin is unlikely to tighten sufficiently with non-surgical treatment.
Your skin quality and the extent of excess tissue will also affect your suitability. If you have large folds of loose skin, surgery may offer a more appropriate option than additional treatment sessions.
How Can You Tell Loose Skin From Remaining Fat?
Loose skin may appear crepey or gather into folds, while remaining fat contributes volume beneath your skin. Both can occur together after weight loss, making it difficult to judge your concerns from appearance alone.
Your practitioner should assess the area and explain whether treatment is more likely to improve skin firmness, body contours or both. This distinction helps you understand what results are realistic.
Should You Wait Until Your Weight Has Stabilised Before Treatment?
If you’re still losing weight, it may be better to wait until your weight has stabilised before considering Exilis Ultra 360. Further weight loss can change your body shape and make it harder to assess how much loose skin remains.
Waiting allows your practitioner to evaluate your skin more accurately and recommend a suitable approach. If you’ve had bariatric surgery, discuss the timing with your bariatric team or GP, as your recovery and nutritional health may also affect treatment planning.
Clinical Tip
Before booking Exilis Ultra 360 after weight loss, ask your practitioner to assess each treatment area separately. It may help to discuss whether your main concern is mild wrinkling, loose skin, remaining fat or folds that interfere with your comfort.
Ask for an explanation of the likely improvement, number of sessions, total cost and possible alternatives. If you’ve had bariatric surgery, make sure any ongoing nutritional or medical concerns have been reviewed before aesthetic treatment begins.
Does How You Lost Weight Affect Your Treatment Options?
Whether you lost weight through lifestyle changes, medication or bariatric surgery, the amount of loose skin and your overall health influence treatment suitability. Significant skin folds may require surgical assessment regardless of how you lost weight.
If you have undergone bariatric surgery or used weight-loss medication, discuss your medical history, weight stability and nutritional health before arranging aesthetic treatment.
What Does Clinical Research Say About Exilis Ultra 360 for Loose Skin?
Research suggests that combined radiofrequency and ultrasound treatments may improve skin firmness and body contouring in selected areas. However, the available studies are relatively small and don’t establish how effective Exilis Ultra 360 is for significant loose skin after major weight loss.
The findings also don’t prove that non-surgical treatment can replace surgical skin removal. You should therefore discuss the available evidence with your practitioner and ask what results you can realistically expect.
How Many Exilis Ultra 360 Sessions Might You Need After Weight Loss?
You may need around four to six Exilis Ultra 360 sessions, although the recommended number depends on your skin laxity, treatment area and goals. Some protocols use weekly or fortnightly appointments, with improvements potentially developing after your final session.
More sessions won’t necessarily improve significant loose skin if the treatment isn’t suitable for your concerns. Before starting, ask your practitioner about the proposed schedule, total cost and how your results will be assessed.
When Will You Notice Results, and How Much Improvement Is Realistic?
You may notice subtle changes after your first few sessions, but lasting improvements can take several weeks to develop. Your practitioner may suggest reviewing your results one to three months after completing the course.
If you’ve lost significant weight, remember that firmer-looking skin doesn’t necessarily mean excess folds will disappear. Results vary, so discuss realistic expectations with your practitioner before starting treatment.
Research Insight
A 2021 retrospective study published in the Journal of Cosmetic Dermatology assessed 64 patients who received four weekly sessions of combined radiofrequency and ultrasound treatment. Researchers recorded reductions in body circumference one month after treatment, with an average patient satisfaction score of 4.48 out of 5.
However, the study did not include an untreated comparison group and focused on body circumference rather than excess skin removal. It therefore cannot establish how effectively Exilis Ultra 360 improves significant loose skin after substantial weight loss or how long any improvement will last.
What Does Exilis Ultra 360 Treatment and Recovery Feel Like?
During Exilis Ultra 360 treatment, your practitioner moves an applicator over the chosen area to deliver controlled heat. You may feel warmth similar to a heated massage, although the sensation can vary depending on your skin sensitivity and treatment area.
Afterwards, you may notice temporary redness, warmth, mild swelling or tenderness, which usually settles relatively quickly. You can often return to normal activities soon after treatment, but follow your practitioner’s aftercare advice and report any sharp pain or burning immediately.
What Are the Risks, and Who Should Avoid Exilis Ultra 360?
Although Exilis Ultra 360 is non-surgical, you may experience redness, swelling or tenderness after treatment. Less common risks include burns, blistering, pigmentation changes and scarring, particularly if treatment isn’t delivered appropriately.
Before treatment, tell your practitioner about any medical conditions, medicines, implanted devices, metal implants or previous procedures. The manufacturer’s contraindications include pregnancy or IVF treatment, pacemakers, implanted defibrillators, metal implants, active infections and isotretinoin use within the previous 12 months. Recent deep peeling, poor wound healing and certain other medical conditions may also make treatment unsuitable. Your practitioner must review the full contraindication list and confirm your suitability before proceeding.
UK Guidance Note
The UK’s Advertising Standards Authority requires providers to hold appropriate evidence for objective claims about cosmetic treatment results. Claims that Exilis Ultra 360 can significantly tighten loose skin after major weight loss, provide permanent improvement or replace surgical skin removal would need robust evidence specifically supporting those outcomes.
UK professional guidance also recognises that substantial excess skin after weight loss can cause functional problems, including irritation and reduced mobility. If your skin folds affect your daily activities or repeatedly become inflamed, your clinician should discuss medical assessment and appropriate treatment alternatives rather than assume cosmetic tightening is sufficient.
How Long Could Your Results Last, and Will You Need Maintenance?
Your results may last for several months, but the duration varies between individuals. Weight changes, ageing and skin quality can all influence how your treated areas look over time, and claims of results lasting up to two years aren’t firmly established by clinical evidence.
You may consider maintenance treatment if you’re happy with the initial improvement, but there’s no standard schedule for loose skin after weight loss. Your practitioner should reassess your skin before recommending further sessions.
When Is Surgery More Appropriate Than Exilis Ultra 360?
If you’ve lost a significant amount of weight and have large folds of excess skin, surgery may be more suitable than Exilis Ultra 360. Procedures such as a tummy tuck, arm lift or thigh lift can physically remove surplus skin and create more noticeable contour changes.
However, surgery involves scars, risks and a longer recovery period. Your surgeon can assess your health, weight stability and concerns to help you compare the benefits and limitations of each approach.
