Loose skin beneath your upper arms, often called bingo wings, can develop with age, weight loss or natural changes in your skin. You may notice it more when raising your arms or wearing sleeveless clothing.
Exilis Ultra 360 uses radiofrequency and ultrasound to help improve mild skin laxity and upper-arm firmness. However, results depend on whether your concern involves loose skin, localised fat or both.
What Are Bingo Wings and Why Do Your Upper Arms Become Loose?
Bingo wings is an informal term for loose skin or soft tissue hanging beneath your upper arms. You may notice this more when raising your arms or wearing short sleeves, particularly as your skin loses firmness with age.
Weight loss, genetics and changes in collagen and elastin can all contribute to this appearance. It’s important to identify whether your concern is excess skin, underlying fat or a combination of both, as this can affect which treatment is most suitable.
Are Your Bingo Wings Caused by Loose Skin or Localised Fat?
Loose skin and localised fat can both affect the appearance of your upper arms, but they need different approaches. If you have thin, wrinkled or folded skin, laxity may be the main concern, whereas fuller, softer arms may indicate more underlying fat.
You may also have a combination of both, particularly after weight loss. Your practitioner can assess your skin elasticity and fat distribution to determine whether Exilis Ultra 360 is likely to address your main concern.
Why Do Bingo Wings Remain Even When You Exercise?
Strength training can improve the muscles beneath your upper-arm skin, helping your arms appear more defined. However, exercise cannot directly remove excess skin or reliably eliminate localised fat from one particular area.
If your bingo wings mainly involve mild skin laxity, Exilis Ultra 360 may be worth discussing. Significant hanging skin may require a surgical approach, while remaining fat may need a different assessment.
How Does Exilis Ultra 360 Work on Your Upper Arms?
Exilis Ultra 360 combines radiofrequency and ultrasound to deliver controlled heat beneath your skin. This may encourage collagen remodelling and gradually improve the firmness and appearance of your upper arms.
The treatment uses an applicator with cooling and temperature-monitoring features to support controlled energy delivery. Unlike an arm lift, it doesn’t remove excess skin, so results are likely to be modest if you have significant sagging.
Evidence Note
A 2017 study published in the Journal of Cosmetic Dermatology evaluated 34 participants receiving four weekly treatments with combined radiofrequency and ultrasound technology. Seven participants received treatment for upper-arm fat deposits, while others were treated for facial skin laxity or body-contouring concerns.
Although researchers reported encouraging cosmetic outcomes, the arm-treatment group was small and did not specifically establish how much loose upper-arm skin could be tightened. These findings suggest possible benefits for selected body-contouring concerns but do not guarantee improvement in bingo wings caused by significant skin laxity.
Can Exilis Ultra 360 Tighten Bingo Wings Without Surgery?
Exilis Ultra 360 may help improve mild upper-arm laxity without surgery. You may notice smoother, firmer-looking skin, although the degree of improvement depends on your skin quality and the extent of sagging.
If you have large folds of hanging skin, particularly after significant weight loss, treatment may not provide the results you want. Your practitioner can assess your arms and explain whether non-surgical tightening or an arm lift is more suitable.
Who Is Most Suitable for Exilis Ultra 360 Upper-Arm Treatment?
You may be suitable for Exilis Ultra 360 if you have mild upper-arm skin laxity and want a non-surgical option. It may be worth considering if you’re happy with a modest improvement rather than a dramatic lifting effect.
Your practitioner will assess your skin, medical history and treatment goals to determine whether the procedure is appropriate. Having a stable weight and realistic expectations can also help you judge the results.
Clinical Tip
Before booking Exilis Ultra 360 for bingo wings, ask your practitioner to assess your skin elasticity, underlying fat and degree of sagging. Your upper arms may have different amounts of loose skin, so each side should be examined individually.
Discuss the expected improvement, number of sessions, total cost and treatment alternatives before proceeding. If you’ve previously had surgery, lymph-node treatment or persistent swelling in either arm, make sure your practitioner reviews this history as part of your safety assessment.
How Much Improvement Can You Realistically Expect in Your Upper Arms?
You may notice slightly firmer, smoother-looking skin and a modest improvement in your upper-arm contours after treatment. However, the results depend on your skin quality, degree of laxity and individual response.
Exilis Ultra 360 won’t remove large folds of excess skin or produce the same reshaping as an arm lift. Your practitioner may use before-and-after photographs to help you assess any changes more accurately.
What Does Clinical Research Say About Exilis Ultra 360 for Arms?
Research suggests that combined radiofrequency and ultrasound treatments may improve selected body-contouring measurements. However, you should be aware that studies involving the arms have included small groups and don’t clearly establish how effectively Exilis Ultra 360 can tighten your loose upper-arm skin.
You shouldn’t expect the treatment to remove your bingo wings or guarantee long-lasting results. Larger studies with longer follow-up are needed to show how reliably it can improve your upper-arm skin laxity.
Research Insight
A 2021 retrospective study published in the Journal of Cosmetic Dermatology assessed 64 patients receiving four weekly sessions of combined radiofrequency and ultrasound treatment. Seven patients received upper-arm treatment, and researchers reported changes in body circumference one month after the final appointment.
However, the study did not include an untreated comparison group, and circumference measurements do not establish how much loose skin was tightened. The findings provide preliminary evidence for body contouring but cannot reliably predict improvements in upper-arm laxity.
Can Exilis Ultra 360 Improve Bingo Wings After Weight Loss?
If you’ve lost weight but still have loose skin beneath your upper arms, Exilis Ultra 360 may help improve mild laxity. You may notice some improvement in firmness if your skin retains enough elasticity, although results after significant weight loss aren’t well established.
If you have large folds of hanging skin, treatment is unlikely to provide substantial correction, and an arm lift may be more suitable. Your practitioner should assess your skin and weight-loss history, and you may benefit from waiting until your weight has stabilised.
Can Exilis Ultra 360 Reduce Upper-Arm Fat as Well as Tighten Skin?
Exilis Ultra 360 may offer modest improvements in localised upper-arm fullness as well as skin firmness. However, you shouldn’t assume it will significantly reduce stubborn fat or remove loose skin.
Your practitioner will need to establish whether your main concern is excess fat, skin laxity or both. This is important because reducing fat doesn’t always tighten your skin, and the most suitable treatment will depend on your individual needs.
When Should You Seek Medical Advice About Upper-Arm Swelling?
Not every change in your upper-arm appearance is caused by loose skin or fat. Persistent swelling, particularly after lymph-node treatment or surgery, may need medical assessment before you consider cosmetic treatment.
If an arm becomes suddenly swollen, painful, red or hot without an obvious cause, seek urgent medical advice through your GP or NHS 111. Exilis Ultra 360 should not be used to treat unexplained swelling.
Bingo Wings: Which Treatment May Be Suitable?
| Upper-Arm Concern | Potential Treatment | Important Limitation |
| Reduced muscle tone | Strength training | Cannot remove hanging skin |
| Mild skin laxity | Exilis Ultra 360 may be considered | Visible tightening is not guaranteed |
| Localised fat with good skin elasticity | Liposuction may be considered | Does not reliably tighten excess skin |
| Mild laxity with some localised fat | Individualised non-surgical assessment | Fat reduction and skin tightening are different outcomes |
| Significant hanging skin | Arm lift (brachioplasty) | Requires surgery and leaves permanent scars |
| Skin folds causing repeated irritation | Medical or surgical assessment | Cosmetic tightening may not address the underlying problem |
How Is Exilis Ultra 360 Treatment Planned for Both Upper Arms?
Your practitioner should assess each upper arm separately before planning treatment. This helps account for differences in skin firmness, laxity and tissue distribution.
1. Individual assessment: Each arm may have a different degree of looseness or fullness.
2. Treatment areas: Your practitioner will identify the specific areas you want to improve.
3. Progress photographs: Images may be taken to help compare changes over time.
4. Treatment plan: You should understand the expected sessions, treatment areas and overall cost.
A personalised assessment helps ensure the treatment plan reflects your individual upper-arm concerns.
How Many Exilis Ultra 360 Sessions Might You Need for Bingo Wings?
You may need several Exilis Ultra 360 sessions, depending on your skin condition and treatment goals. The two published studies discussed above used four weekly treatments, although your practitioner may recommend a different schedule after assessing your upper arms.
Your practitioner should monitor how your upper arms respond before recommending further sessions. If you’re seeing little improvement, more appointments may not help, so discuss your progress and expectations before continuing.
What Affects the Cost of Exilis Ultra 360 for Your Arms?
Your treatment cost will depend on the clinic, number of sessions and whether one or both upper arms require treatment. Some providers offer treatment packages, while others charge for individual appointments.
Before booking, ask for a written quotation covering the full recommended course, consultation, follow-up appointments and any additional charges. Compare the total cost with the expected improvement, particularly if you may need alternative treatment.
What Does an Exilis Ultra 360 Upper-Arm Session Feel Like?
During treatment, your practitioner moves an applicator over your upper arms to deliver controlled radiofrequency and ultrasound energy. You may feel warmth similar to a hot-stone massage, although the sensation can vary depending on your sensitivity and the area being treated.
If the heat becomes painful or uncomfortable, tell your practitioner straight away. You may notice temporary redness, warmth or mild tenderness afterwards, but you can usually return to your normal activities relatively quickly.
When Will Your Upper Arms Start Looking Firmer, and How Long Might Results Last?
You may notice gradual improvements in your upper-arm firmness over several weeks rather than immediately after your first session. Your results may become clearer after completing the recommended course, with your practitioner reviewing the changes around one to three months later.
How long your results last depends on your skin quality, age and weight changes. You may consider maintenance treatment later, but there’s no established schedule, so your practitioner should reassess your arms before recommending further sessions.
What Side Effects and Safety Precautions Should You Know About?
Although Exilis Ultra 360 is non-surgical, you may experience temporary redness, warmth, swelling or tenderness after treatment. Less common risks include burns, blistering, pigmentation changes and scarring, so you should understand these possibilities before proceeding.
Before treatment, tell your practitioner about any medical conditions, medicines, implanted devices, metal implants, previous arm surgery, lymph-node treatment, unexplained swelling or changes in skin sensation. 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, pronounced swelling and impaired sensation in the treatment area may also make treatment unsuitable. Your practitioner must review the full contraindication list and confirm your suitability. If you develop severe pain, blistering or worsening swelling afterwards, seek medical advice.
UK Guidance Note
The UK’s Advertising Standards Authority requires cosmetic treatment providers to hold suitable evidence for objective claims about effectiveness. Statements suggesting that Exilis Ultra 360 can eliminate bingo wings, produce substantial upper-arm tightening or provide guaranteed long-lasting results need appropriate clinical substantiation.
Because research specifically assessing loose upper-arm skin is limited, your practitioner should explain what the available studies actually measured. You should be given realistic expectations about possible improvements, risks and alternatives rather than promises of surgical-level results.
How Should You Prepare for Treatment and Care for Your Arms Afterwards?
Before treatment, tell your practitioner about your medical history, medicines, previous cosmetic procedures and any skin sensitivity or healing problems. You may also be asked to arrive with clean skin and avoid certain products on your upper arms.
Afterwards, you may notice temporary warmth or redness, so follow your clinic’s aftercare instructions while your skin settles. Avoid rubbing or exfoliating the area, protect your arms from excessive sun exposure and contact your practitioner if your recovery doesn’t follow the expected pattern.
Is Exilis Ultra 360 Better Than Exercise, Liposuction or an Arm Lift?
The best option for your bingo wings depends on whether you’re concerned about loose skin, excess fat or both. Exercise can strengthen your arm muscles, while Exilis Ultra 360 may offer modest skin tightening without surgery.
If you have stubborn fat, liposuction may be worth discussing, whereas an arm lift can remove significant excess skin. Your practitioner can assess your upper arms, explain the benefits and limitations of each option, and help you choose an approach that matches your expectations.

Frequently Asked Questions
1. Can Exilis Ultra 360 get rid of bingo wings?
Exilis Ultra 360 may improve mild loose skin beneath your upper arms by encouraging collagen remodelling. However, it won’t remove large folds of excess skin or provide the same results as an arm lift.
2. What causes bingo wings to develop?
Bingo wings can develop due to ageing, weight loss, genetics and changes in collagen and elastin. These factors can reduce skin firmness and contribute to loose tissue beneath your upper arms.
3. How can you tell whether your bingo wings are caused by fat or loose skin?
Thin, wrinkled or folded skin may indicate skin laxity, while fuller, softer arms may suggest underlying fat. You may have both, so a practitioner should assess your skin elasticity and fat distribution.
4. Can Exilis Ultra 360 tighten loose arms after weight loss?
It may improve mild upper-arm laxity if your skin retains enough elasticity. However, significant hanging skin after weight loss is unlikely to respond substantially and may require an arm lift.
5. Who is a suitable candidate for Exilis Ultra 360 on the upper arms?
You may be suitable if you have mild skin laxity, a stable weight and realistic expectations about gradual improvement. Your practitioner will also consider your medical history and treatment goals.
6. How many Exilis Ultra 360 sessions do you need for bingo wings?
Published Exilis-related studies have used four weekly sessions, although the number you may need depends on your skin laxity and treatment goals. Your practitioner should recommend an individual schedule and assess your progress before suggesting further treatment.
7. Does Exilis Ultra 360 reduce upper-arm fat as well as tighten skin?
It may offer modest improvements in localised fullness and skin firmness, but it isn’t designed to remove significant amounts of fat. Your treatment plan will depend on whether your main concern is excess fat, loose skin or both.
8. When will you see firmer-looking upper arms after treatment?
You may notice gradual changes over several weeks, with results becoming clearer after completing your recommended sessions. Your practitioner may review your progress around one to three months later.
9. What side effects can you experience after Exilis Ultra 360 on your arms?
You may experience temporary redness, warmth, swelling or mild tenderness. Less common risks include burns, blistering, pigmentation changes and scarring, so discuss the potential risks with your practitioner beforehand.
10. Is Exilis Ultra 360 better than liposuction or an arm lift for bingo wings?
The most suitable option depends on whether you have loose skin, excess fat or both. Exilis Ultra 360 may help with mild laxity, liposuction addresses stubborn fat, and an arm lift can remove significant excess skin.
Final Thoughts: Exilis Ultra 360 for Bingo Wings and Loose Arms
If you’re concerned about loose skin beneath your upper arms, Exilis Ultra 360 may offer a non-surgical way to improve mild laxity and skin firmness. However, it won’t remove significant excess skin, so the right approach depends on whether your bingo wings are caused by loose skin, localised fat or both.
