Bat wings, commonly known as bingo wings, describe loose, sagging skin and soft tissue hanging from the underside of the upper arms. The concern may involve loose skin alone, excess fat, reduced muscle tone or a combination of all three.
Some patients notice mild crepiness and early loss of firmness, while others develop a more prominent fold of skin and fat extending from the armpit towards the elbow. The appearance may become more noticeable when the arms are raised, moved or held away from the body.
Bat wings frequently develop following natural ageing, menopause, significant weight loss or repeated changes in body weight. Genetics, sun damage, smoking and reduced collagen production may also contribute.
At Skin and Scar Care Clinic, we provide medically led, personalised treatments designed to improve upper-arm contours without surgery where clinically appropriate.
Depending on your anatomy, your treatment plan may include:
- Endolift® laser-assisted contouring
- Bio Remodelling / Bio Stimulator® Body
- Diluted or hyperdiluted calcium hydroxylapatite
- Fractional CO₂ laser resurfacing
- HIFU or microfocused ultrasound
- Radiofrequency or RF microneedling
- Non-surgical fat-reduction treatments
- Referral for surgical brachioplasty where necessary
The aim is to create firmer, smoother and better-defined upper arms while maintaining a natural appearance.
What Causes Bat Wing Arms?
Natural Ageing
Collagen, elastin and hyaluronic acid gradually decline with age. As the skin becomes thinner and less elastic, it may no longer remain tightly supported against the upper arm.
This can result in:
- Loose or hanging skin
- Fine wrinkling
- Crepey texture
- Reduced firmness
- Poor definition between the arm and armpit
Age-related changes in muscle mass and fat distribution can make this laxity more noticeable.
Significant or Rapid Weight Loss
When body weight increases, the skin stretches to accommodate the additional volume. Following significant or rapid weight loss, the skin may not contract completely, particularly where its collagen and elastin fibres have already been weakened.
Patients who have lost weight through lifestyle changes, bariatric surgery or weight-management medication may notice residual loose skin affecting the inner arms.
The amount of skin retraction depends on several factors, including:
- Age
- Genetics
- Amount of weight lost
- Speed of weight loss
- Duration of previous weight gain
- Smoking history
- Sun exposure
- Existing stretch marks
- Overall skin quality
Non-surgical treatment can improve mild or moderate laxity, but it cannot remove a large hanging fold of excess skin.
Localised Upper-Arm Fat
Some people naturally store more fat around the upper arms, even when they are close to their target weight.
A soft, pinchable layer of fat may create fullness beneath the arms and reduce the visible definition of the shoulders and upper arms.
Fat-reduction treatments may be considered when this fatty layer is a significant part of the concern. However, removing fat without addressing poor skin elasticity can sometimes make loose skin appear more noticeable.
Loss of Muscle Tone
The triceps muscles provide underlying shape and support to the back of the upper arm. Reduced muscle mass may cause the arms to appear softer and less defined.
Resistance exercise can improve muscle tone and overall arm shape, but exercise cannot remove excess skin or guarantee fat loss from one specific area.
Genetics
Genetics influence:
- Where the body stores fat
- Skin thickness
- Collagen quality
- Natural arm shape
- How effectively the skin retracts following weight loss
Some patients therefore develop bingo wings despite maintaining a healthy weight and active lifestyle.
Hormonal Changes
Hormonal changes during menopause and midlife may affect fat distribution, muscle mass, collagen production and skin hydration.
These combined changes can lead to thinner, looser and more crepey upper-arm skin.
Smoking
Smoking reduces circulation and negatively affects collagen production and wound healing. Long-term smoking may accelerate skin ageing and contribute to thinning, wrinkling and loss of elasticity.
Smoking may also increase the risk of complications following invasive, injectable and laser treatments.
Sun Damage
Repeated ultraviolet exposure breaks down collagen and elastin within the skin.
Although the inner arms may receive less sun exposure, the outer and posterior arms can develop:
- Uneven pigmentation
- Fine wrinkles
- Roughness
- Thinning
- Loss of firmness
- Sunspots
Previous Liposuction or Surgery
Uneven fat removal, scar tissue or poor skin contraction following previous liposuction can produce irregularities, folds or skin laxity.
These patients require careful assessment because scar tissue and altered anatomy may affect the choice and safety of further treatment.
Conditions We Treat
Our personalised upper-arm treatment plans may be considered for:
- Bat wings
- Bingo wings
- Loose upper-arm skin
- Mild to moderate upper-arm laxity
- Crepey inner-arm skin
- Localised upper-arm fat
- Poor upper-arm definition
- Wrinkled or thinning arm skin
- Mild post-weight-loss skin laxity
- Upper-arm stretch marks
- Uneven texture following liposuction
- Early age-related arm changes
- Combined fat and skin laxity
Is the Problem Fat, Loose Skin or Both?
Correct assessment is essential before choosing a treatment.
A large-looking arm does not necessarily contain a large amount of fat. In some patients, the appearance is primarily caused by loose skin. In others, a localised layer of fat stretches the skin and contributes to the hanging fold.
During your consultation, we assess:
- The amount and distribution of fat
- Skin thickness and elasticity
- The degree of hanging skin
- Whether the tissue is soft, fibrous or scarred
- Upper-arm muscle tone
- Stretch marks and sun damage
- Previous weight loss
- Previous surgery or liposuction
- Medical history and medication
- Your expectations and available recovery time
We will explain whether your concern is likely to respond to non-surgical treatment or whether a surgical arm lift would provide a more predictable result.
Recommended Treatments for Bat Wings and Bingo Arms
Endolift® for the Upper Arms
Endolift® is a minimally invasive laser-assisted procedure performed beneath the skin using a very fine optical fibre.
Laser energy is delivered directly into selected subdermal tissues to stimulate tissue contraction and collagen remodelling. Where appropriate, it may also be used to target a small or moderate layer of superficial fat.
Published evidence on intralesional 1470 nm laser treatment suggests potential benefits for skin laxity and localised adipose tissue, including treatment of the arms. However, much of the evidence consists of relatively small or non-randomised studies, and larger controlled studies are still required.
What Can Endolift® Improve?
Endolift® may help to:
- Tighten mildly or moderately loose upper-arm skin
- Improve the appearance of bat wings
- Reduce selected superficial fat pockets
- Stimulate collagen remodelling
- Improve the transition between the upper arm and armpit
- Refine upper-arm contours
- Improve selected irregularities after previous liposuction
- Create a firmer foundation for subsequent skin treatments
Who May Be Suitable for Upper-Arm Endolift®?
Suitable patients commonly have:
- Mild to moderate upper-arm skin laxity
- A small or moderate pinchable fat layer
- Early or moderate bingo wings
- Loose skin following modest weight loss
- Reasonably good underlying skin quality
- Stable body weight
- Realistic expectations
- A preference for minimally invasive treatment
- Sufficient time to allow swelling and collagen remodelling
When Endolift® May Not Be Suitable
Endolift® may not be recommended where there is:
- Severe hanging skin
- A large volume of excess fat
- Advanced laxity following massive weight loss
- Pregnancy or breastfeeding
- Active infection or open wounds
- Uncontrolled diabetes
- Poor wound healing
- An unstable medical condition
- A significant bleeding disorder
- Anticoagulant medication that cannot be safely managed
- Severe vascular or neurological disease affecting the arms
- Unexplained swelling or a new lump
- Unrealistic expectations
- Inability to follow aftercare instructions
Previous surgery, liposuction or scarring does not automatically prevent treatment, but a more detailed assessment may be required.
Endolift® Recovery and Results
Endolift® is usually performed as a single initial procedure. A second session may occasionally be considered after full healing where significant residual laxity remains.
Temporary effects may include:
- Swelling
- Bruising
- Tenderness
- Firmness
- Temporary altered sensation
- Mild asymmetry during healing
- Temporary contour irregularity
Early tightening may become visible as the initial swelling settles. Collagen remodelling continues gradually, and the final result is normally assessed over approximately three to six months.
Endolift® is not a substitute for brachioplasty where there is severe excess skin.
Endolift® Combined With Fractional CO₂ Laser
Endolift® and fractional CO₂ laser work at different tissue levels.
- Endolift® treats selected deeper subdermal tissue and superficial fat.
- Fractional CO₂ laser treats the skin surface and dermis to improve texture, fine wrinkles and collagen remodelling.
A combined treatment may be considered where a patient has:
- Mild or moderate hanging skin
- Crepey skin overlying the lax area
- Fine wrinkles and textural changes
- Stretch marks
- Skin laxity following weight loss
- Reduced skin quality following previous fat reduction
- Both deeper laxity and surface ageing
Direct evidence for fractional CO₂ laser treatment of upper-arm laxity remains limited, with published arm-contouring evidence including a successful clinical case report. It is therefore most appropriately considered a surface-remodelling treatment rather than a replacement for deeper tightening or surgical skin removal.
Benefits of the Combination
The combination may help to address:
- Deeper tissue laxity
- Small superficial fat pockets
- Crepey skin
- Fine wrinkles
- Stretch marks
- Uneven texture
- Overall skin firmness
Can Endolift® and CO₂ Laser Be Performed Together?
In carefully selected patients, both procedures may be performed during the same treatment episode.
However, staged treatment may be preferable where:
- A larger area requires treatment
- Stronger laser settings are planned
- The patient has a darker skin type
- There is a history of pigmentation
- There is significant swelling after Endolift®
- The patient has previous surgical scars
- Additional healing time is required
The final decision is made following clinical assessment.
CO₂ Laser Recovery
Depending on the treatment intensity, temporary effects may include:
- Redness
- Swelling
- Pinpoint bleeding
- Crusting
- Sensitivity
- Itching
- Temporary darkening or lightening of the skin
Initial healing commonly takes approximately one to two weeks. Redness or altered pigmentation may remain for longer.
Patients with darker skin tones may have a greater risk of post-inflammatory hyperpigmentation and require carefully selected settings, pre-treatment preparation and strict aftercare.
Bio Remodelling / Bio Stimulator® Body for Crepey Upper-Arm Skin
Bio Remodelling / Bio Stimulator® Body is an injectable hyaluronic-acid-based bioremodelling treatment developed to improve skin hydration, elasticity and laxity.
It is particularly suitable where the main concern is poor skin quality rather than a large volume of fat.
A 2026 clinical study of inner upper-arm laxity reported improvement following treatment with hybrid high- and low-molecular-weight hyaluronic acid complexes. A recent systematic review also reported improvements or trends towards improvement in hydration, elasticity, density and laxity across treated facial and body areas, including the inner arms. These studies are encouraging, although some research involved manufacturer-affiliated investigators and should be interpreted in that context.
What Can Bio Remodelling / Bio Stimulator® Body Improve?
Bio Remodelling / Bio Stimulator® Body may help to improve:
- Mild upper-arm skin laxity
- Crepey texture
- Reduced hydration
- Thin or ageing skin
- Fine wrinkling
- Loss of elasticity
- Skin quality following weight loss
- Skin quality after Endolift® or another contouring treatment
Bio Remodelling / Bio Stimulator® Body does not directly remove a meaningful pocket of fat.
Typical Bio Remodelling / Bio Stimulator® Body Course
An initial treatment course commonly involves:
- Two sessions
- Approximately four weeks apart
- Review following the second treatment
- Maintenance according to skin condition and response
Improvement develops gradually as hydration and tissue remodelling take place.
Bio Remodelling / Bio Stimulator® Body May Not Be Suitable Where There Is:
- Pregnancy or breastfeeding
- Active infection in the treatment area
- Known hypersensitivity to the product
- Significant bleeding or bruising risk
- An uncontrolled autoimmune or inflammatory condition
- Poor wound healing
- Severe loose skin requiring surgical removal
- Unrealistic expectations
Temporary swelling, bruising, tenderness, redness and small injection-site bumps may occur.
Diluted or Hyperdiluted CaHA for the Upper Arms
Calcium hydroxylapatite(CAHA), commonly abbreviated to CAHA, is an injectable collagen-stimulating treatment.
When diluted or hyperdiluted, CAHA can be placed within the appropriate tissue plane to support dermal remodelling rather than primarily creating volume.
What Can CAHA Improve?
Diluted or hyperdiluted CAHA may help to:
- Improve dermal thickness
- Stimulate collagen production
- Improve skin elasticity
- Reduce crepiness
- Strengthen thin upper-arm skin
- Improve mild to moderate laxity
- Support the skin after fat reduction
- Enhance the result of Endolift®
- Improve selected surface irregularities
CAHA is primarily used to improve skin structure and firmness. It does not remove a substantial volume of upper-arm fat.
Typical CAHA Treatment Course
Depending on the degree of laxity, treatment may involve:
- One initial session
- Review after approximately eight to twelve weeks
- A second treatment where clinically required
- Gradual improvement over two to six months
- Maintenance according to individual response
Who May Be Suitable?
CaHA may be considered for patients with:
- Mild or moderate skin laxity
- Thin or crepey upper-arm skin
- Reduced dermal support
- Stable body weight
- Limited excess fat
- Realistic expectations
- Skin requiring additional support after Endolift®
CaHA May Not Be Suitable Where There Is:
- Pregnancy or breastfeeding
- Active skin infection
- Known hypersensitivity to the product
- Significant bleeding risk
- Uncontrolled inflammatory or autoimmune disease
- Severe skin excess
- Poor healing
- A history of significant injectable complications requiring investigation
- Unrealistic expectations
Possible complications include swelling, bruising, tenderness, inflammation, infection, palpable nodules, asymmetry and vascular injury.
Body treatment with CaHA may be outside the specific licensed indication of an individual product. Any off-label use will be explained clearly during consultation and consent.
Endolift® and Bio Remodelling / Bio Stimulator® Body Combination
This combination may be particularly helpful where a patient has:
- A small or moderate fatty layer
- Mild or moderate tissue laxity
- Crepey skin
- Reduced hydration and elasticity
- Post-weight-loss changes
Endolift® is usually performed first to treat the deeper tissues. Bio Remodelling / Bio Stimulator® Body may then be introduced once the initial inflammation has settled.
Example Timeline
Week 0: Endolift® treatment
Weeks 1–4: Recovery and reduction of swelling
Weeks 4–8: First Bio Remodelling / Bio Stimulator® Body treatment, subject to healing
Four weeks later: Second Bio Remodelling / Bio Stimulator® Body treatment
Months 3–6: Review of tissue contraction and skin quality
The exact timing varies according to healing and the extent of treatment.
Endolift® and Hyperdiluted CaHA Combination
Endolift® may be combined with CaHA where the deeper tissue requires tightening but the overlying skin also needs greater collagen support.
This may be considered for:
- Moderate crepiness
- Thin skin following weight loss
- Reduced dermal thickness
- Mild residual laxity after Endolift®
- Poor skin quality without severe excess skin
A clinical study combining microfocused ultrasound with diluted or hyperdiluted CaHA found improvements in objective and subjective measures of upper-arm skin laxity over six months, supporting the principle of combining deeper energy-based treatment with injectable collagen stimulation.
Example Timeline
Week 0: Endolift®
Weeks 6–12: CaHA treatment after adequate healing
Months 3–6: Collagen-remodelling review
After six months: Further treatment considered only if required
Endolift®, Biostimulator and CO₂ Laser Combination
Patients with multiple concerns may benefit from a staged programme involving:
- Endolift® for deeper laxity and selected superficial fat.
- Bio Remodelling / Bio Stimulator® Body or hyperdiluted CaHA for hydration, dermal quality and collagen support.
- Fractional CO₂ laser for crepiness, fine wrinkles, stretch marks and surface refinement.
Not every patient requires all three stages. Treatment is selected according to the relative contribution of fat, laxity and skin texture.
Example Comprehensive Timeline
Month 0: Endolift®
Month 1–2: Clinical review
Month 2: First Bio Remodelling / Bio Stimulator® Body treatment or CaHA treatment
Month 3: Second Bio Remodelling / Bio Stimulator® Body treatment, where prescribed
Month 3–4: Fractional CO₂ laser, subject to complete healing
Month 6: Final review of collagen remodelling and arm contour
Other Evidence-Based Treatments
HIFU and Microfocused Ultrasound
High-intensity focused ultrasound and microfocused ultrasound deliver energy at selected depths to stimulate thermal contraction and collagen remodelling.
Clinical studies, including a randomised controlled trial, have reported improvement in mild to moderate upper-arm skin laxity after microfocused ultrasound treatment. Another study found that combining microfocused ultrasound with CaHA improved arm firmness and elasticity over 24 weeks.
HIFU may be considered for patients who:
- Have mild or moderate laxity
- Do not require substantial fat reduction
- Prefer a non-invasive treatment
- Accept gradual and potentially modest improvement
- Are unable or unwilling to undergo Endolift®
Results usually develop gradually over approximately two to six months.
HIFU may not be appropriate over open wounds, active infection, certain implanted devices, severe loss of sensation or areas where the underlying anatomy cannot be safely identified.
Radiofrequency Treatment
Radiofrequency devices heat selected tissue layers to stimulate collagen contraction and remodelling.
Depending on the device, treatment may be:
- Non-invasive
- Microneedle-assisted
- Subdermal and minimally invasive
A prospective study of subdermal radiofrequency reported improvement in posterior upper-arm laxity, although the study was small.
Radiofrequency treatment may help with:
- Mild laxity
- Crepey skin
- Fine wrinkles
- Reduced firmness
- Surface texture
- Skin tightening following fat reduction
A course of several treatments may be required with non-invasive RF or RF microneedling.
RF microneedling should be used cautiously in patients with implanted electronic devices, active infection, poor wound healing, significant bleeding risk or a tendency towards abnormal scarring.
Cryolipolysis
Cryolipolysis uses controlled cooling to reduce a localised layer of subcutaneous fat.
Small clinical studies have reported measurable reduction in upper-arm fat thickness following cryolipolysis. However, the treatment primarily reduces fat and does not reliably tighten significantly loose skin.
Cryolipolysis may be considered where:
- A defined, pinchable fat pocket is present
- Skin elasticity is reasonably good
- The patient prefers a non-invasive treatment
- Fat, rather than loose skin, is the main concern
It may not be the best option where there is significant laxity because reducing the fat layer can occasionally make hanging skin more visible.
Rare complications include persistent pain, altered sensation and paradoxical enlargement of the treated fat.
Injectable Fat-Reduction Treatments
Fat-dissolving injections may sometimes be considered for a very small and carefully selected fat pocket.
However, the upper arms can require treatment over a relatively broad area. This may result in:
- Significant swelling
- Discomfort
- Multiple injections
- Several treatment sessions
- Uneven fat reduction
- Increased risk of contour irregularity
In the UK, licensed deoxycholic-acid treatment is intended for fat beneath the chin rather than the upper arms. Use elsewhere on the body would be off-label and requires careful assessment and explicit consent.
Fat-dissolving injections do not directly correct severe loose skin.
Poly-L-Lactic Acid
Poly-L-lactic acid is another injectable biostimulator that may improve dermal support and skin quality gradually.
Treatment may require more than one session, and results develop gradually over several months.
Resistance Training and Weight Management
Exercise cannot remove excess skin, but resistance training can strengthen the triceps, shoulders and upper back to improve underlying muscle tone.
A supportive programme may include:
- Triceps exercises
- Shoulder strengthening
- Upper-back exercises
- Adequate dietary protein
- Stable weight maintenance
- Smoking cessation
- Sun protection
Patients who are actively losing weight may be advised to postpone definitive treatment until their weight is reasonably stable.
When Is Surgical Brachioplasty More Appropriate?
Brachioplasty, commonly known as an arm lift, surgically removes excess skin and may be combined with liposuction where appropriate.
Surgery may provide a more predictable result for:
- Severe hanging skin
- Advanced bat wings after massive weight loss
- A large excess of skin extending towards the chest
- Significant fat and skin excess
- Patients seeking a more dramatic transformation
- Laxity unlikely to respond adequately to non-surgical treatment
The trade-off is a permanent scar along the inner or posterior arm, together with the risks and recovery associated with surgery.
Published surgical literature recognises brachioplasty as an important treatment for severe upper-arm laxity, particularly following massive weight loss.
We will provide an honest assessment if a non-surgical treatment is unlikely to achieve your goals.

Who Is a Good Candidate for Non-Surgical Arm Contouring?
Suitable candidates are generally:
- In good overall health
- At or close to a stable weight
- Troubled by mild or moderate laxity
- Affected by a small fat pocket
- Able to follow aftercare instructions
- Non-smokers or willing to reduce smoking
- Realistic about the degree of improvement
- Prepared to allow several months for collagen remodelling
Who May Not Be Suitable?
Treatment may not be appropriate or may need to be postponed where there is:
- Pregnancy or breastfeeding
- Active infection
- Open wounds or dermatitis
- Uncontrolled diabetes
- Poorly controlled hypertension
- Significant bleeding risk
- Severe vascular disease
- Impaired sensation
- Poor wound healing
- Unstable autoimmune or inflammatory disease
- Recent surgery
- Continuing significant weight loss
- Severe skin excess
- Unexplained arm swelling
- A new or changing lump
- Unrealistic expectations
- Inability to follow aftercare
Sudden, painful, red or one-sided arm swelling requires medical assessment rather than cosmetic treatment.
Your Upper-Arm Rejuvenation Journey
Stage 1: Comprehensive Assessment
We assess:
- Skin quality
- Degree of laxity
- Fat distribution
- Muscle tone
- Previous weight loss
- Scars and stretch marks
- Previous treatment
- Medical history
- Your treatment priorities
Standardised photographs and measurements may be taken to support treatment planning and follow-up.
Stage 2: Primary Contouring Treatment
Where fat and deeper laxity are present, Endolift® may be recommended as the first stage.
Where laxity is mild and fat is minimal, HIFU, radiofrequency or an injectable biostimulator may be more appropriate.

Bio Remodelling / Bio Stimulator® Body or hyperdiluted CaHA may be introduced to improve hydration, firmness, elasticity and dermal support.
Stage 4: Surface Refinement
Fractional CO₂ laser or RF microneedling may be recommended for:
- Crepiness
- Fine wrinkles
- Stretch marks
- Uneven texture
- Photodamage
Stage 5: Review
Collagen remodelling is gradual. A meaningful review is usually performed over approximately three to six months rather than immediately after treatment.
Stage 6: Maintenance
Results may be supported through:
- Stable weight
- Resistance exercise
- Adequate protein intake
- Smoking cessation
- Sun protection
- Recommended skincare
- Periodic maintenance treatment where appropriate
Frequently Asked Questions
Can Endolift® Remove Bingo Wings?
Endolift® may improve mild to moderate bingo wings where there is a combination of superficial fat and skin laxity.
It cannot remove a severe hanging fold of excess skin. Patients with advanced laxity may require surgical brachioplasty.
Does Bio Remodelling / Bio Stimulator® Body Remove Arm Fat?
No. Bio Remodelling / Bio Stimulator® Body improves hydration, elasticity and skin quality. It does not directly remove upper-arm fat.
Do CaHA Injections Reduce Fat?
No. Diluted or hyperdiluted CaHA is used to stimulate collagen and improve dermal support. It is not a fat-dissolving treatment.
What Does CO₂ Laser Treat?
Fractional CO₂ laser primarily improves:
- Crepey skin
- Fine wrinkles
- Stretch marks
- Uneven texture
- Surface collagen remodelling
It does not remove a substantial amount of fat and cannot replace surgical skin removal.
Which Treatment Is Best for Bingo Wings?
The best treatment depends on the cause:
- Mainly fat with mild laxity: Endolift® or another fat-reduction treatment.
- Mainly loose skin: Endolift®, HIFU, radiofrequency or a biostimulator.
- Crepey skin: Bio Remodelling / Bio Stimulator® Body, CaHA, fractional CO₂ laser or RF microneedling.
- Fat, laxity and crepiness: A staged combination treatment.
- Severe hanging skin: Surgical arm-lift assessment.
How Many Sessions Will I Need?
A personalised programme may include:
- One initial Endolift® procedure
- Two Bio Remodelling / Bio Stimulator® Body sessions four weeks apart
- One or two CaHA treatments
- One to three fractional CO₂ laser sessions
- A course of RF microneedling
- One or more HIFU treatments
The number of sessions depends on your anatomy, healing response and desired outcome.
When Will I See Results?
Results vary according to the treatment:
- Endolift®: early change after swelling settles, with continued improvement over three to six months.
- Bio Remodelling / Bio Stimulator® Body: gradual improvement following the initial two-treatment course.
- CaHA: progressive collagen stimulation over approximately two to six months.
- CO₂ laser: improvement develops as the skin heals and remodels over several months.
- HIFU or RF: gradual tightening over approximately two to six months.
Are the Results Permanent?
The improvements can be long-lasting, but no non-surgical treatment permanently stops ageing.
Remaining fat cells can enlarge with future weight gain, and the skin will continue to lose collagen naturally over time.
Maintaining a stable weight and healthy lifestyle can help preserve the result.

Important Disclaimer
The information on this page is intended for general education and does not replace a medical consultation.
All medical, injectable and laser procedures carry risks. Potential complications may include pain, bruising, swelling, bleeding, infection, burns, altered sensation, pigmentation changes, delayed healing, scarring, nodules, contour irregularity, asymmetry and an incomplete or variable response.
Some treatments or body-area applications may be off-label. Where applicable, this will be clearly explained before treatment and documented during the consent process.
Endolift® and other non-surgical procedures are not alternatives to brachioplasty in patients with severe skin excess. No particular result can be guaranteed. We commit to providing 100% professional effort, but outcomes vary according to anatomy, age, skin quality, smoking history, weight stability, lifestyle and individual healing response.
Recommended Treatments
RF Microneedling
Radiofrequency microneedling stimulates collagen and elastin production deep within the skin, helping to tighten loose upper arm skin and improve texture, firmness, and elasticity over time.
HIFU (High-Intensity Focused Ultrasound)
HIFU delivers focused ultrasound energy into the deeper structural layers of the skin, promoting collagen remodelling and tissue tightening. It is an effective non-surgical treatment for mild to moderate upper arm skin laxity.
Collagen-Stimulating Injectables
Biostimulatory injectable treatments encourage the body's natural collagen production, gradually improving skin quality, firmness, and structural support. These treatments are ideal for patients seeking long-term skin rejuvenation.
Fat Dissolving Injections (Suitable Patients Only)
Where excess localised fat contributes to the appearance of bingo wings, fat dissolving injections may be recommended for carefully selected patients. These treatments can help reduce small pockets of fat while being combined with skin tightening procedures for optimal contouring.
