Best treatment for loose, crepey skin in Brasília (abdomen, arms, thighs)
The right option depends on whether skin is crepey, loose or hanging. Mild to moderate laxity can be treated without surgery; an overhanging apron cannot.
Agendar ConsultaShort answer: match the treatment to how loose the skin is
The best treatment for loose skin depends on which of three problems you have: crepey texture, true laxity, or an overhanging apron of excess skin. Crepey and mildly loose skin on the abdomen, arms and thighs can be treated without surgery, with radiofrequency, micro-focused ultrasound, a hyperdiluted collagen biostimulator, or a combination. An apron or major excess after large weight loss is a surgical problem, which Dr. Thiago Perfeito (CRM-DF 23199, INTI clinic, Lago Sul, Brasília) assesses but does not operate on, and refers. The same logic applies to what is now called “Mounjaro body” or “Ozempic body”: loose skin after weight loss on tirzepatide (Mounjaro) or semaglutide (Ozempic).
This problem is usually searched by what people see in the mirror, not by device name: "crepey arms", "saggy belly skin", "Mounjaro body", "loose skin after Mounjaro", "loose skin after Ozempic". That is the right starting point, because the same device does not suit every complaint. Skin that looks thin and wrinkled like crepe paper responds to a different approach than skin that hangs in a fold, and neither responds like a lower abdomen that overhangs the waistband.
This page is organised by the complaint and by body area. If you would rather compare devices head to head, that is covered in best skin tightening treatment in Brasília. If your loose skin followed major weight loss and you also want a plan for the face, see post-weight loss aesthetic recovery in Brasília. The rest of this page assumes one question: given what your skin looks like, which route is honest for you?
Dr. Thiago Perfeito has no commercial relationship with any manufacturer mentioned on this page. Options are named inside their category, and each is matched to an indication rather than ranked by brand.
Crepey, loose or hanging: three different problems
"Loose skin" is a lay term that covers three distinct findings. Telling them apart is the first step, because it decides whether a non-surgical plan is realistic.
Crepey skin
The surface is thin, finely wrinkled and often slightly shiny, and it wrinkles when pinched or when you change position, but it does not hang. It shows up on the inner arms, the upper abdomen and the inner thighs. The main deficit is dermal quality: less collagen and elastin support in the skin itself. This is the finding where non-surgical treatment has the most room to help.
Loose skin without a fold
The skin has lost tension and sags slightly when you stand, but there is no distinct hanging fold. Examples are a soft lower abdomen after pregnancy or moderate weight loss, and arms that move when waved. Both the dermis and the layer beneath it have lost support. Non-surgical treatment is realistic here, usually as a combination rather than a single device.
Hanging skin or an apron
Skin and fat hang as a fold over the waistband, or drape from the arm when it is raised (the "bat wing"). The skin is stretched beyond what it can retract, and energy devices and injectables cannot remove tissue that is present in surplus. This is the group for whom surgery, such as an abdominoplasty or arm lift, is the honest answer.
A simple home check is a pinch and a lift. If the skin springs back quickly and mainly looks crinkled, it is likely crepey. If it stays folded for a moment and can be gathered in a handful, it is likely lax. If, when you stand relaxed, a fold hangs without you touching it, it is likely excess skin. The check is only a screen; the examination also looks at skin thickness, stretch marks, scars and the fat underneath, none of which you can judge at home.
Mounjaro body and Ozempic body: why skin loosens after GLP-1 weight loss
“Mounjaro body” and “Ozempic body” are lay names, not diagnoses, for the loose, deflated look some people notice after losing weight on these medications. Mounjaro is the brand name of tirzepatide (Eli Lilly); Ozempic and Wegovy are brand names of semaglutide. The mechanism in the skin is the same as after any substantial weight loss, and so is the way it is assessed: crepey, lax or excess.
Skin is an envelope that adapts to the volume beneath it. When that volume shrinks quickly, the envelope has less time to retract, and the collagen and elastin in the dermis, already stretched, are limited in how much they can recover. Age, sun exposure, smoking, genetics, previous pregnancies and how long the higher weight lasted all affect how much recoil is left.
Body composition during medication-driven weight loss has also been measured. A body-composition sub-study of the SURMOUNT-1 trial, published in Diabetes, Obesity and Metabolism in 2025, used DXA scans in 160 participants (124 on tirzepatide, the active ingredient of Mounjaro, 36 on placebo) over 72 weeks. In the tirzepatide group, body weight fell by 21.3%, fat mass by 33.9% and lean mass by 10.9%; in both groups, roughly three quarters of the weight lost was fat and about a quarter was lean mass. These are whole-body figures, not measurements of the abdomen, arms or thighs, and the authors have links to the drug's manufacturer. What they show is that weight lost this way includes some lean mass as well as fat. The study did not measure skin.
In SURMOUNT-5, published in the New England Journal of Medicine in 2025 (751 participants without diabetes, 72 weeks, funded by the drug's manufacturer), tirzepatide produced a 20.2% weight reduction versus 13.7% with semaglutide, and waist circumference fell by 18.4 cm versus 13.0 cm. Those are trial averages for medication outcomes; the trial did not assess skin.
Dr. Thiago Perfeito does not prescribe or manage GLP-1 medications. Dose, changes and stopping belong to the prescribing physician, and nothing on this page suggests altering them. Dr. Thiago Perfeito treats the aesthetic consequence, and asks that weight be stable before planning, because energy devices and injectables act on the skin you have now, and a body that keeps changing changes the plan.
Crepey, lax or excess: which option fits (table with ranges)
The table matches each finding to the option best suited to it, with the range at the INTI clinic in Brasília. Values are per session unless stated, and the position within a range depends on the area, its size and the number of sessions defined at assessment. A price far below these ranges is a warning sign: it can mean a diluted product or a split vial, a device used at the wrong depth, or inexperience.
| Degree / type | Best-matched option | How it works | Range at INTI clinic |
|---|---|---|---|
| Mild crepey texture, thin skin (arms, upper abdomen, inner thighs) | Hyperdiluted calcium hydroxyapatite biostimulator | A more dilute preparation is injected superficially over a wider area to stimulate collagen and elastin, rather than to add volume | R$ 2,900–3,900 per box; the number of boxes depends on the area |
| Mild laxity, texture and early looseness (abdomen, thighs) | Micro-focused ultrasound (Ultraformer MPT) | Focused ultrasound heats small points in deeper tissue to promote contraction and collagen remodelling, without needles | R$ 1,900–9,000 per session |
| Mild to moderate laxity with skin roughness, larger areas (abdomen) | Dual-frequency monopolar radiofrequency (XERF) | Two radiofrequency frequencies delivered in sequence within one pulse with cooling, heating the layers between dermis and subcutaneous tissue | R$ 2,900–12,000 per session by area; the abdomen sits near the top of the range. Protocol: one session every 6 months |
| Moderate laxity with dermal thinning (abdomen, thighs) | Radiofrequency microneedling (Morpheus8 body) | Insulated needles deliver radiofrequency energy into the deep dermis and subdermis, combining micro-injury with heat to remodel | Abdomen R$ 6,000–12,000 per session; thighs and buttocks R$ 6,000–12,000 per session; arms priced by area at assessment |
| Moderate laxity affecting several body areas | Combination protocol: RF microneedling + biostimulator + micro-focused ultrasound | Combines different depths and mechanisms, so texture, support and contraction are addressed in one sequenced plan | R$ 15,000–45,000 for the protocol |
| Overhanging apron, hanging arm skin, major excess | Surgical route (abdominoplasty, arm lift), with referral | Removes excess skin, which energy and injectables cannot do | Not performed by Dr. Thiago Perfeito; surgeon fees vary by surgeon and hospital |
The ranges above are the clinic's, not a market average. They cover the option, not a guaranteed outcome: how far the skin tightens depends on its starting thickness, elasticity and weight history.
Which option for which body area
Abdomen
The abdomen is the largest of the three areas. Mild laxity with a crinkled texture suits micro-focused ultrasound or dual-frequency radiofrequency; moderate laxity with thin skin suits radiofrequency microneedling, often with a biostimulator. In a preclinical study published in Lasers in Medical Science in 2025, using a computational model and pig skin, the 2 MHz frequency of a dual-frequency device heated more deeply and widely in fat, while 6.78 MHz heated along the fibrous septa; the combination acted at the junction between dermis and subcutaneous tissue, remodelling collagen and elastin without killing fat cells. That is laboratory evidence about how the energy behaves, from authors linked to the manufacturer, and it does not by itself show how much a given abdomen will tighten. The clinical studies of XERF reviewed for this page evaluated the face only; its use on the abdomen is a clinical choice based on the device's mechanism, not on a body trial.
Arms
Crepey inner arms are one of the areas where a hyperdiluted biostimulator is used. A practical guide published in Aesthetic Surgery Journal in 2022, written from the experience of 12 experienced injectors as part of a medical education programme rather than a trial, describes hyperdiluted calcium hydroxyapatite used on the face, arms, hands, neck, chest, abdomen, buttocks and thighs, and on cellulite and stretch marks. It explains that a more dilute product goes in more superficially and over a larger area to stimulate collagen and elastin, whereas an undiluted product is used for volume. A drooping arm with a fold when raised is a different problem, and belongs in the surgical group.
Thighs
Loose skin on the inner thighs behaves like the abdomen: mild to moderate laxity responds to radiofrequency microneedling, micro-focused ultrasound or a biostimulator. When the complaint is dimpled texture rather than looseness, the relevant page is best cellulite treatment in Brasília; when it is a flat or deflated buttock, see best flat buttock treatment in Brasília.

When surgery is the honest answer
Non-surgical treatment improves skin quality and, in mild to moderate cases, produces visible tightening. It does not remove tissue. If you have a fold of skin that hangs over the waistband, skin that drapes from the arm, or the sort of excess left by a very large weight loss, energy devices and injectables can improve texture and support but will not change the amount of skin present. Recommending repeated sessions in that situation would be spending money on a result that cannot be delivered.
The surgical routes are an abdominoplasty for the abdomen and an arm lift (brachioplasty) for the arms. Dr. Thiago Perfeito does not perform body surgery, including abdominoplasty, liposuction, breast surgery or buttock implants. When a case belongs there, the correct step is to examine, say so plainly, and refer to a surgeon, rather than sell a device protocol. Surgery on the body also carries scars, recovery time and its own risks, and a surgeon should discuss those with you before you decide.
Some people are in between: enough excess that surgery is on the table, but not ready or not willing. For them, a non-surgical plan can be a reasonable step to improve what can be improved, as long as the expectation is set at the start that it is not a substitute for removing surplus skin. If you are planning surgery, mention it at the consultation, because the timing of treatments relative to surgery matters.
The sequence that makes sense is the same in every case: stable weight first, then a clinical assessment that classifies the skin as crepey, lax or excess, then a plan. Anyone who quotes a protocol without examining the skin has skipped the step that decides everything else.

Frequently asked questions about loose skin treatment
What is the best loose skin treatment in Brasília?
There is no single best treatment; it depends on the type of laxity. Crepey or mildly loose skin on the abdomen, arms and thighs can be treated non-surgically with radiofrequency, micro-focused ultrasound, a hyperdiluted biostimulator or a combination, while an overhanging apron of skin is a surgical problem. Dr. Thiago Perfeito, CRM-DF 23199, assesses which group you belong to at the INTI clinic in Lago Sul.
How can I tighten loose skin without surgery?
Non-surgical options act on the skin you have: radiofrequency microneedling and monopolar radiofrequency heat the deeper layers to remodel collagen, micro-focused ultrasound delivers focused heat without needles, and hyperdiluted biostimulators stimulate collagen. They improve texture and, in mild to moderate cases, tighten, but they cannot remove excess skin. Weight should be stable first.
What can I do about crepey skin on my arms?
Crepey inner arms are one of the areas where a hyperdiluted calcium hydroxyapatite biostimulator is used, sometimes combined with radiofrequency. A practical guide from 12 experienced injectors describes this use on the arms, among other areas, though it is expert experience rather than a trial. If the arm skin hangs as a fold when raised, the honest answer is an arm lift.
What is “Mounjaro body” and how is it treated?
“Mounjaro body” is a lay name, not a diagnosis, for loose or deflated skin on the abdomen, arms, thighs or buttocks after weight loss on tirzepatide (Mounjaro); the same picture after semaglutide is called “Ozempic body”. Once weight is stable, the skin is examined and classified as crepey, lax or excess: mild to moderate laxity can be treated with radiofrequency, micro-focused ultrasound or biostimulators, and major excess needs surgery. Dr. Thiago Perfeito does not prescribe or manage these drugs; dose, changes and stopping stay with the prescribing physician.
What can I do about loose skin after Mounjaro or Ozempic?
Wait until weight is stable, then have the skin examined and classified as crepey, lax or excess. Mild to moderate laxity can be treated with radiofrequency, ultrasound or biostimulators, and major excess needs surgery. Dr. Thiago Perfeito does not prescribe or manage these drugs; dose, changes and stopping stay with the prescribing physician.
How much does loose skin treatment cost at INTI clinic?
Ranges per session at INTI clinic are: micro-focused ultrasound R$ 1,900–9,000; XERF R$ 2,900–12,000 by area, with the abdomen near the top; Morpheus8 on the abdomen or thighs R$ 6,000–12,000; and a hyperdiluted biostimulator R$ 2,900–3,900 per box. A multi-technology combination protocol is R$ 15,000–45,000. A price far below these ranges can signal dilution, a split vial or inexperience.
Can non-surgical treatment replace a tummy tuck?
Not when there is an overhanging fold or a large excess of skin, because devices and injectables improve skin quality but do not remove tissue. It can help mild to moderate laxity, or serve as a step for people not ready for surgery. Dr. Thiago Perfeito does not perform abdominoplasty, and refers those cases after assessment.
How do I check that the doctor is qualified?
Confirm an active registration at cfm.org.br under the doctor search. Dr. Thiago Perfeito is registered as CRM-DF 23199. Also ask what the doctor does and does not perform, whether products are traceable and registered with Anvisa, and whether the assessment happens in person before any price is quoted.
How many sessions will I need?
It depends on the type of laxity, the area and the option chosen; radiofrequency microneedling is usually planned as a series, and the XERF protocol at the clinic is one session every 6 months. The number is defined after the in-person examination, and the plan is reviewed before more sessions are added.
