Ozempic Face: What It Is and How to Treat Facial Sagging After Weight Loss
Does your face look thinner or saggier after losing weight with Ozempic? What Ozempic face is, how to prevent it and how to treat it. Dr. Alejandra Téllez, Bogotá.
You lost weight with Ozempic, Mounjaro, the so-called "peptides" or another medication, and you feel better… but when you look in the mirror, your face looks thinner, tired or saggy. Social media calls this Ozempic face, and it's one of the most common reasons patients see me in Bogotá lately. The good news: there's an explanation, and it can be treated. This guide sums up what I explain in my office.
What is Ozempic face?
Ozempic face is not a disease. It's the popular name for the changes that show up in the face when you lose a lot of weight in a short time:
- Hollow cheeks and flatter cheekbones
- Deeper under-eye circles and hollow temples
- Deeper lines from the nose to the mouth (nasolabial folds)
- Looser skin on the jawline, under the chin and on the neck
- A more aged or tired-looking face
Ozempic and Wegovy (semaglutide) and Mounjaro (tirzepatide) are medications for diabetes and obesity. In large trials, people lost an average of 15% of their body weight with semaglutide (1) and up to 21% with tirzepatide (2). That's a huge loss, and the face shows it too.
Why does the face sag after weight loss?
The face has fat pads that give it volume and support the skin. When you lose weight, those pads shrink. If the skin can't adjust in time, it's left with extra slack and sags.
A review published in 2026 in Aesthetic Surgery Journal found that the midface loses roughly 7% of its volume for every 10 kg of weight lost. The loss is greater in the superficial fat, right under the skin (3).
An important point: it's not unique to Ozempic. The same changes happen after bariatric surgery or a very strict diet. What matters most is how much weight you lose, your age and the quality of your skin (3, 4). After 40, the skin has less collagen and has a harder time bouncing back.
How to prevent Ozempic face
If you're starting treatment or you're partway through, these steps help protect your skin:
- Don't stop your medication on your own. The health benefits far outweigh the cosmetic change. Any adjustment should be decided with your prescribing doctor.
- Eat enough protein and do strength training. They help you keep muscle, not just lose fat.
- Sunscreen every day. The sun breaks down collagen and speeds up sagging.
- Retinoids at night to stimulate collagen. I explain how to start in my retinoids guide.
- See a dermatologist early. It's easier to manage the change along the way than to correct it at the end.
Treatments for facial sagging after weight loss
There is no single treatment. An international expert consensus published in 2026 recommends assessing each area of the face separately and tailoring the plan to age, sex and how much weight was lost (5). These are the options, from gentlest to most intensive.
Collagen biostimulators
These are injections that prompt your skin to make its own collagen, such as poly-L-lactic acid (Sculptra). Results appear gradually, over 2 to 3 months, and look natural. A systematic review found that the effect of poly-L-lactic acid lasts up to 25 months (6). Usually 2 or 3 sessions are needed. Read more in my article on Sculptra and facial biostimulation.
Hyaluronic acid
It restores volume right away in the areas that hollow out the most: cheekbones, temples, under-eyes and jawline. Done well, it doesn't "puff up" the face: it supports it. The effect lasts on average 6 to 18 months, depending on the area and the product. See how I work with hyaluronic acid.
Skin quality treatments
When there are also fine lines, dark spots or uneven texture, a CO2 laser or a chemical peel improves the skin's surface and stimulates collagen.
Combining treatments
In practice, the best results usually come from combining: a biostimulator for firmness, hyaluronic acid for volume and a surface treatment for texture. Evidence in patients who lost weight with these medications is still limited and comes mostly from studies without a comparison group (3). That's why every plan is tailored.
When is the best time to treat it?
My usual advice is to wait until your weight is stable, or close to your goal. If we treat while you're still losing weight, your face will keep changing and you may need touch-ups sooner. In the meantime, you can start with skin care and, in some cases, with biostimulators.
When should you see a dermatologist?
Book a visit if your face has changed more than you expected, if you look tired or older even though you feel well, or if you're considering fillers and don't know where to start. In my office I assess your skin, your fat pads and where you are in your treatment, and I propose a step-by-step plan.
Frequently asked questions
Is Ozempic face permanent? Not entirely. If you regain weight, some volume comes back. If you keep the weight off, the sagging can be improved with dermatologic treatments.
How can I avoid Ozempic face? By eating enough protein, doing strength training, wearing sunscreen and seeing a dermatologist from the start of treatment.
Does Mounjaro also cause Ozempic face? Yes. Any large, fast weight loss can cause it, whether from tirzepatide, semaglutide, surgery or diet.
When can I get fillers if I'm still losing weight? Ideally once your weight is stable or close to your goal, so the result lasts longer.
Should I stop my medication to avoid losing facial volume? No. Never stop it without talking to your prescribing doctor: your face can be treated, and your health comes first.
Lost weight and no longer recognize your face in the mirror? In my office I assess your skin and recommend the treatment that brings back your freshness without looking "done." Book your appointment with Dr. Alejandra Téllez, dermatologist in Bogotá.
