Non-surgical upper arm laxity treatment in Marylebone, London. Skin firming, muscle toning and targeted fat reduction, matched to what is behind your arms.
Dr Joney De Souza Clinic treats plenty of upper arms, usually brought in by the same moment: a wave, a photo, a sleeveless dress reconsidered. Upper arm laxity is the soft, loose skin along the back of the upper arm, between shoulder and elbow, known less kindly as bingo wings, a nickname we would happily retire. The area is mostly a skin laxity story rather than a fat story, which surprises people, and it changes what actually works.
Upper arm skin is thinner than it looks and in constant motion, so it shows collagen decline early. Age eases the skin’s elastic recoil, weight loss can leave skin the body no longer fills, the triceps behind the arm often quietly under work, and genetics set how resilient the skin was to begin with. Most arms we see carry two or three of these at once, in different proportions.
That proportion decides the plan: firm the skin, tone the muscle, reduce the fat pocket, or a measured combination. Our clinic assesses honestly, including where non surgical treatment reaches its limits, because firmer arms you keep come from matching the treatment to the cause and protecting the collagen you rebuild for the years ahead.
Upper arms loosen for different reasons, and each responds to a different hand. Find the pattern that sounds like your arms, then follow it through. Your practitioner confirms the mix at consultation, including an honest word on where non surgical treatment reaches its limits.
Loose, crepey upper arm skin
When collagen and elastin decline, the skin on the back of the arm loses its snap and starts to move independently. Radiofrequency heat rebuilds collagen exactly there, and where the surface has gone finely crepey, laser resurfacing can renew it alongside.
The triceps have clocked off
The triceps run along exactly the line where the loosening shows, and an under worked triceps leaves nothing beneath the skin to hold shape. Electromagnetic stimulation works the muscle far beyond a gym set, building tone that supports the arm from within.
Diet resistant, exercise proof
Some upper arms carry a localised pocket of fat that diet and exercise never quite reach. Targeted heat reduces it and slims the contour, and it pairs naturally with skin firming so the smaller arm also looks tighter.
Skin the body no longer fills
Significant weight loss deserves its own plan, because skin, muscle and remaining fat all shift at once, and more advanced laxity improves rather than vanishes without surgery. A consultation maps the honest picture, and where a surgical opinion is the truthful answer, we say so plainly.

Four routes to firmer looking arms: skin, muscle, fat and surface, usually paired rather than picked. Where skin quality across the body needs broader support, Profhilo and polynucleotides, performed by our doctors, improve firmness and hydration in treated areas, and TempSure extends to other body areas that loosen alongside the arms.
Radiofrequency firming
Radiofrequency heat warms the deeper skin layers to the point where collagen rebuilds, firming crepey, lax arm skin over a course. It feels like a warm massage and needs no recovery time.
A course of four to six is standard.
Muscle stimulation
Electromagnetic pulses contract the triceps thousands of times a session, building the tone that holds the back of the arm in shape. The structure under the skin is half the answer.
A course of six to eight, no downtime.
Targeted fat reduction
A wrap around applicator delivers deep, targeted heat to the stubborn pocket of fat along the upper arm, slimming the contour where diet and exercise rarely reach.
A course of three is standard.
Laser skin quality
Where the arm skin itself has gone finely lined and papery, laser resurfacing renews the surface and stimulates collagen beneath it, improving texture and firmness together.
One to three sessions.
Every plan at Dr Joney De Souza Clinic starts with an honest look at what the arm is actually made of: how much is loose skin, how much is soft muscle tone, how much is a fat pocket, and how the three sit together. Your practitioner assesses skin quality and elasticity, checks how the tissue responds to a gentle pinch and lift, and asks about weight history and training, because arms that have lost weight and arms that have lost collagen want different plans.
You will also hear clearly what non surgical treatment can and cannot do for your degree of laxity, because managed expectations are part of the service, not an afterthought.
“My ‘less is more’ approach has become the mainstay of my practice and clients appreciate that they will have natural looking results.”
Dr Joney De Souza, speaking to The Sybarite
Here is what happens before, during and after treatment at our Marylebone clinic.
Your consultation maps the skin, muscle and fat contribution and sets the sequence, since combinations work best in the right order. There is little preparation needed: come hydrated for radiofrequency and muscle work, and avoid sun exposure on the arms for two weeks if laser is part of the plan.
TempSure feels like a warm massage moving over the arm, FlexSure like deep steady warmth, and StimSure like an intense, oddly effortless triceps workout. Sessions run twenty to forty five minutes and none of them need anaesthetic. Most people read or chat through them.
You can go straight back to your day after every one of these treatments. Muscle work can leave next day soreness like a good gym session, and laser brings a few days of redness and flaking. The real change builds over two to three months as collagen, tone and contour respond, which is when we review.
Two of the three causes respond to homework. Triceps work, from press downs to dips, builds the muscle that supports the back of the arm, and it compounds beautifully with in clinic muscle stimulation. Skin quality responds to daily moisturising, retinoid based body care and SPF on arms that see the sun, which slows the collagen loss that started the whole thing.
Where home effort runs out of road is loose skin itself. Once elasticity has gone, no cream or exercise pulls the skin tight again, because the collagen scaffolding needs rebuilding from within, and that is what the energy based treatments are for.
What treatment will not do. We would rather say this plainly. Non surgical arm treatments firm, tone and slim within honest limits, and significant laxity improves rather than vanishes. Results vary between people, build gradually over months, and keep best with maintenance and a little triceps work of your own. Where surgery is the truthful answer, we will say exactly that.

The questions our Marylebone team hears most often about upper arms, from what causes the loosening to what treatment involves and costs. If yours is not here, message us on WhatsApp and a practitioner will answer properly.
It depends on what is behind yours. Loose, crepey skin responds to TempSure Firm radiofrequency, missing muscle tone to StimSure, a stubborn fat pocket to FlexSure, and papery skin texture to UltraClear. Most arms do best with a combination.
Improved, honestly and visibly, yes; erased, not always. Mild to moderate laxity responds well to skin firming, muscle toning and fat reduction in combination. More advanced loose skin improves rather than resolves, and if a surgical opinion is the truthful answer for your arms, we will say so at consultation.
Because the wave is usually skin, not fitness. Exercise builds the triceps and burns fat, but it cannot restore elasticity to skin whose collagen has declined with age or weight change. That is why fit arms can still wave, and why skin firming treatments exist alongside the gym.
It stimulates the skin to firm itself. Radiofrequency warms the deeper layers to the temperature where collagen production restarts, and over a course of four to six sessions the skin gradually firms and smooths. It suits mild to moderate laxity best, feels like a warm massage and has no downtime.
It rebuilds the structure under the skin. Electromagnetic pulses contract the triceps thousands of times per session, far beyond what a workout achieves, building tone along exactly the line people mean when they say bingo wings. Firmer muscle beneath makes the whole arm look tighter, with no downtime at all.
A localised pocket, yes. FlexSure wraps the area and delivers targeted heat that reduces the stubborn fat diet and exercise rarely reach, over a course of three sessions. It is a contouring treatment for a pocket rather than a weight loss method, and we are upfront about that difference.
Courses, rather than one offs, because arms respond gradually: four to six for TempSure, six to eight for StimSure, three for FlexSure and one to three for laser. Combination plans sequence these sensibly rather than stacking everything at once, and you get an honest number at consultation.
Essentially none. Every option here is walk in, walk out: expect brief warmth and redness after radiofrequency, next day muscle soreness after StimSure, and mild warmth after FlexSure. Laser resurfacing is the exception, with a few days of redness and flaking on the treated skin.
Skin firming and fat reduction build over two to three months as collagen rebuilds and the body clears treated fat, with muscle tone showing a little sooner. Arms photographed before treatment and at the three month review are the honest comparison, and results keep best with maintenance.
They last well when maintained. New collagen and muscle tone are yours, though ageing continues, so an occasional maintenance session and a little triceps work protect the result. Fat cells reduced by heat do not return, though remaining ones can still grow with significant weight gain.
Usually an assessment before anything, because post weight loss arms mix loose skin, changed fat distribution and often under used muscle. The sequence matters more than the menu: commonly skin firming first, muscle tone alongside, and contouring last. Your plan is mapped honestly at consultation.
At our clinic, StimSure starts from £100 per session, TempSure Firm from £250, and FlexSure from £350, with course rates bringing per session costs down. Laser resurfacing on the arms is priced by area at consultation. Our full price list has the detail.
