Loose skin & GLP-1 medications
Loose Skin After Ozempic®, Wegovy®, or Mounjaro®: What to Expect and What Can Help
If you're losing a meaningful amount of weight on a GLP-1 medication and you're noticing loose or sagging skin, you're not imagining it, and it doesn't mean you're doing anything wrong. Skin laxity is a recognized, non-rare change after substantial or rapid weight loss. For many people it improves somewhat over the months that follow as skin gradually adjusts, though some looseness often remains — particularly after larger amounts of weight loss — and how much varies a lot from person to person. There's no single guaranteed fix. But understanding why it happens, what actually affects how much you'll have, and what genuinely helps with day-to-day comfort in the meantime can make this part of the journey a lot easier to navigate.
What this page covers
This page is written for anyone currently losing weight with a GLP-1 medication — semaglutide (Ozempic®, Wegovy®), tirzepatide (Mounjaro®), or similar — who is noticing or worried about loose skin, particularly around the abdomen, chest, or thighs. You're likely earlier in this process than someone who's had bariatric surgery, and support garments may be a new idea to you. We'll walk through why this happens, what's within your control and what isn't, practical things that help now, where a support garment fits in (and where it doesn't), when it's worth talking to a doctor, and where surgery fits into the picture. This is general information, not a substitute for advice from your own healthcare provider.
Formal medical research here is still catching up to how fast these medications have been adopted — most of what exists is barely a year or two old, and researchers are still working out exactly how much skin laxity to expect and for whom. But you don't have to take our word that this is a real, common experience: on Reddit, the discussion communities r/Mounjaro and r/WegovyWeightLoss — two of the largest online communities of people actually taking these medications — are full of people describing exactly this, constantly, in their own words. Search “skin” in either one and you'll see for yourself.

Key takeaways
- Loose skin after significant GLP-1-driven weight loss is a known, common experience — not a sign you did anything wrong.
- It often improves somewhat on its own; it may not fully resolve, especially after larger weight loss.
- Genetics, age, how much and how fast you lost, and skin's starting condition all play a role — most of this isn't something you can control through diet or exercise alone.
- For many people this isn't just a cosmetic issue — it can affect mobility, balance, and everyday comfort.
- Non-surgical options genuinely help with comfort, even though none of them “tighten” skin the way surgery can.
- Persistent rash, breakdown, or signs of infection in skin folds are a reason to see a doctor, not just wait it out.
Why can GLP-1 weight loss lead to loose skin?
Skin loses some of its elasticity when the fat layer beneath it shrinks faster than the skin itself can adapt. Skin gets its stretch and “bounce-back” largely from collagen and elastin, and both typically decline somewhat with age. Because GLP-1 medications can produce substantial weight loss relatively quickly for some people, skin sometimes doesn't have time to gradually re-tension the way it might with a slower loss. This isn't unique to GLP-1 medications — the same pattern shows up with any major weight loss, including the weight loss that follows bariatric surgery: each treatment will have its own effect on the body, and for anyone who experiences more significant weight loss, excess skin and tissue can be part of that result.
Will loose skin go away on its own?
For some people, yes, at least partly — skin can continue to adjust and firm somewhat over time as your body settles into a new, stable weight over the next two years. For others, especially after a larger amount of weight loss, some looseness remains even once weight has stabilized, and no amount of time, diet, or exercise fully resolves it. Neither outcome means anything about how hard you worked or how well you're doing — it largely comes down to factors described next, most of which aren't within your control.
What factors affect how much loose skin I may have?
A few things tend to matter most: how much weight you lose (generally, more loss means more potential for laxity), how quickly you lose it, your age (skin's natural elasticity declines somewhat over the years), genetics (some people's skin simply retains more elasticity than others'), and your skin's condition before weight loss began, including prior stretching from pregnancy or previous weight changes. Sun exposure history and smoking are also commonly cited as factors affecting skin elasticity generally. None of these are things you can meaningfully change partway through your journey — which is exactly why the focus for most people shifts to comfort and function rather than prevention.
What can help while my body adjusts?
A few things are worth doing regardless of how your skin responds over time: keeping skin folds clean and dry to reduce friction and irritation, moisturizing to support the skin barrier, staying hydrated, and building strength through movement, which can improve how support garments and clothing fit even when it doesn't change skin laxity itself. Many people also find that clothing and movement adjustments — looser layers in some areas, added support in others — make a meaningful day-to-day difference well before (or instead of) considering any procedure. This is also where a well-fitted support garment can genuinely help, covered next.
How can support garments help with comfort?
What they can do
- Hold excess skin and tissue steady during movement
- Reduce friction and chafing in skin folds
- Make daily activity, exercise, and getting dressed more comfortable
- Sit smoothly and discreetly under everyday clothing
What they can't do
- Tighten skin or change its underlying elasticity
- Speed up skin recovery
- Replace medical or surgical treatment
Anyone telling you a garment will “fix” loose skin isn't being straight with you. The honest case for a support garment is comfort and function, not correction.
When should I talk to a doctor about excess skin?
For some people, loose or excess skin is mainly a cosmetic concern. But for many people, it's more than that — it can genuinely get in the way of mobility, balance, and everyday comfort: making movement harder, adding mechanical strain on the back, hips, and knees, and increasing friction and chafing during normal activity. If excess skin is limiting how you move, exercise, or go about your day, that's worth raising with a doctor — and it's also exactly the kind of everyday problem a well-fitted support garment is built to help with (more on that below).
Some symptoms call for more urgent medical attention, regardless of how much skin you have:
a rash that doesn't improve, or rashes or infections that keep coming back · persistent itching, burning, or pain · cracked, bleeding, or open skin · drainage or a worsening odor · difficulty fully cleaning or drying a skin fold · or pressure pain or skin injury from clothing or a garment.
Those are reasons to see a doctor sooner rather than later, not to wait it out.
It's also reasonable to talk to a doctor simply to understand your longer-term options, including whether and when surgery might make sense for you once your weight has been stable for a while — that's a personal decision with real trade-offs, and your own provider is the right person to walk through it with you.
Is surgery, like a panniculectomy, an option?
For some people, especially after more significant weight loss, non-surgical options aren't enough on their own — and that's a reasonable thing to explore with a doctor. The most common procedure is a panniculectomy: surgery that removes excess skin and fatty tissue (sometimes called the pannus) from the lower abdomen. People typically consider it because of discomfort or a pulling sensation during movement, hygiene challenges in the affected area, interference with physical activity, or simply not being able to find clothing that fits comfortably anymore.
It's not usually a first step. Following significant weight loss — whether from a GLP-1 medication or bariatric surgery — most surgeons recommend waiting until your weight has been stable for a while, often several months to over a year, before pursuing a panniculectomy or similar body-contouring surgery. That waiting period is exactly where non-surgical options like a well-fitted support garment can help most: they don't replace surgical care or your surgeon's guidance, but they can make day-to-day life more comfortable while you and your care team figure out the right timing and approach for you. Whether and when surgery makes sense is a personal decision, made with your surgical team.
Where ActiveMX fits
A practical option for comfort right now
ActiveMX is a men's support garment built specifically for excess skin and tissue after significant weight loss — not repurposed shapewear. It's designed to hold loose skin steady during daily activity and exercise, reduce chafing, and sit smoothly and discreetly under everyday clothing — supporting exactly the mobility, balance, and comfort challenges described above. For someone earlier in a GLP-1 journey who's starting to notice these changes, it's a practical option for comfort and confidence while you figure out your longer-term plan — whether that includes surgery down the road, no procedure at all, or something in between.
To be clear about what it isn't: ActiveMX is not a medical device, doesn't require a prescription, won't tighten your skin, and isn't a substitute for medical advice or a surgical alternative — it's one practical option among several, and it may not be right for everyone. A support garment designed for women is currently in development — see below.
