Ozempic Face: Why Facial Volume Can Change During GLP-1 Weight Loss — and How Nutrition May Help
Whilst losing weight can bring health benefits, from improving blood sugar control and blood pressure to reducing the risk of obesity-related health conditions, using medicines such as semaglutide (Wegovy) or tirzepatide (Mounjaro) as part of a medically supervised weight-loss, can have some side effects.
Some people can notice another change beyond the scales during significant weight loss: their face looks slimmer, more hollow or less plump than before. This is sometimes referred to as “Ozempic face”.
Although the term has become popular online, it is important to understand that “Ozempic face” is not a specific medical condition, nor is facial volume loss unique to Ozempic. It is generally a visible consequence of losing body fat, particularly when weight loss is substantial or relatively rapid. Changes in skin elasticity, hydration and the underlying structures of the face can also contribute.
The good news is that facial changes do not mean you are doing anything wrong. There are also sensible nutritional and lifestyle measures that can support skin health while you continue to lose weight.
What is “Ozempic face”?
“Ozempic face” is an informal term used to describe facial changes that can occur following significant weight loss while taking GLP-1 receptor agonists or other medicines used for weight management.
These changes can include:
A reduction in fullness around the cheeks
More noticeable lines and wrinkles
A hollowed appearance around the temples or under the eyes
More pronounced nasolabial folds
Looser or less taut-looking skin around the jawline and neck
A generally more “drawn” or aged appearance
Importantly, the medication is not necessarily directly “damaging” the skin or removing fat specifically from the face. Rather, the face is one of the places where the body naturally stores fat, so when overall body fat decreases, facial fat can decrease too.
Recent dermatological reviews suggest that facial changes associated with medication-assisted weight loss involve several layers of facial anatomy, including changes in superficial and deeper fat compartments, skin laxity and the relationship between the skin and underlying structures.
Why does weight loss affect the face?
To understand why the face can look different after weight loss, it helps to look at what is happening beneath the skin.
1. Facial fat is reduced
One of the most obvious explanations is simply fat loss.
GLP-1 receptor agonists such as semaglutide work partly by reducing appetite and food intake, helping people maintain a calorie deficit and lose weight. Tirzepatide, which acts on both the GIP and GLP-1 pathways, has a similar overall effect on weight.
When the body loses fat, it does not choose only the areas we might want to change.
Fat is lost from different parts of the body according to individual genetics, hormones, age and body-fat distribution.
The cheeks, temples and areas around the eyes contain fat compartments that contribute to the fullness and contours associated with a youthful face. Reducing these compartments can therefore make the face appear narrower or more hollow.
Research into body composition confirms that modern weight-loss medicines can produce substantial reductions in fat mass, although some lean mass is also lost during significant weight reduction. A 2024 meta-analysis of 22 randomised controlled trials found that GLP-1 receptor agonists reduced both fat mass and lean mass, with lean mass accounting for approximately 25% of total weight lost in the studies analysed.
More recent research similarly suggests that preserving lean tissue should be an important part of a well-designed weight-management programme rather than focusing solely on the number on the scales.
2. Rapid or substantial weight loss can make the change more noticeable
The more weight someone loses, and the faster that loss occurs, the more noticeable changes to facial volume may become.
This is not unique to GLP-1 medication. Similar facial changes can occur after bariatric surgery, intensive dieting or any other situation resulting in substantial weight loss.
Age also matters. Younger skin generally has greater elasticity and may adapt more easily to changes in underlying volume. As we age, collagen and elastin production naturally decline, meaning the skin may not contract as readily following fat loss.
Previous weight gain can also stretch the skin and underlying tissues, potentially making laxity more noticeable after weight loss.
3. Skin structure changes over time
Collagen and elastin are important structural proteins within the skin.
Collagen provides much of the skin's structural framework, while elastin contributes to its ability to stretch and return towards its original shape.
As we age, collagen production and skin elasticity naturally decline. Significant weight loss can reveal this existing loss of elasticity, making wrinkles, folds or loose skin more visible.
It is therefore possible for someone to look healthier overall after losing weight but simultaneously notice more facial lines or reduced facial fullness.
4. Hydration and reduced food intake may play a role
GLP-1 medicines can cause gastrointestinal side effects such as nausea, vomiting, diarrhoea or constipation in some people. These effects can make it more difficult to maintain adequate fluid and food intake.
The medicines also reduce appetite, which is an important part of how they work.
However, a very low appetite can sometimes mean that someone unintentionally eats too little protein, fruit and vegetables or other nutrient-rich foods.
The NHS advises people taking semaglutide to continue eating a healthy, balanced diet and to discuss medicines, vitamins, herbal remedies and supplements with a healthcare professional or pharmacist.
Hydration alone will not restore lost facial fat, but maintaining adequate fluid intake is an important part of supporting normal skin function and overall health.
Can you prevent “Ozempic face”?
There is no guaranteed way to prevent facial volume loss while losing a significant amount of weight.
After all, losing body fat is an intended effect of weight-loss treatment. It would not be realistic to expect to lose fat from the waist, hips or abdomen while keeping exactly the same amount of fat in the face.
However, there are ways to support the quality of weight loss and your skin health.
The most important approach is not necessarily taking a particular supplement. Instead, focus on adequate nutrition, protein, resistance exercise, hydration and a gradual, sustainable approach to weight loss under the guidance of your healthcare team.
Protein: one of the most important nutritional priorities
When appetite is reduced, it can be tempting to focus simply on eating less. However, the goal of medically supervised weight loss should be to reduce excess body fat while maintaining as much muscle and nutritional adequacy as possible.
Protein is particularly important because it supplies the amino acids required for maintaining and repairing tissues, including muscle and skin.
The NHS recommends including protein foods such as beans, pulses, fish, eggs and meat as part of a balanced diet. Dairy products and alternatives such as soya drinks and yoghurt can also provide useful protein.
Your individual protein requirement depends on factors such as body weight, age, activity level, health status and the composition of your diet. Your weight-loss clinician or registered dietitian can help you establish an appropriate target.
This becomes particularly important if you are eating significantly less than before. A 2026 systematic review found that lean mass loss during weight reduction can be substantial and concluded that adequate protein intake, resistance training and body-composition monitoring can help support muscle preservation during incretin-based treatment.
Protein is not a treatment for “Ozempic face”, but maintaining good protein intake is an important part of maintaining healthy tissue and achieving a healthier composition of weight loss.
What about collagen supplements?
Collagen supplements have become extremely popular, particularly among people concerned about skin ageing, wrinkles and loss of firmness.
Collagen is a protein, and many supplements provide hydrolysed collagen peptides, which have been broken down into smaller protein fragments to make them easier to digest.
There is some evidence that oral collagen supplementation may improve certain measures of skin health. For example, a 2023 systematic review and meta-analysis of 26 randomised controlled trials involving 1,721 participants found improvements in skin hydration and elasticity among people taking hydrolysed collagen compared with placebo.
Other systematic reviews have reported similar findings.
However, the evidence is not entirely consistent.
A 2025 systematic review and meta-analysis highlighted an important limitation: when studies were analysed according to funding source and study quality, the apparent benefits were no longer consistently demonstrated. The authors concluded that there was insufficient clinical evidence to recommend collagen supplements specifically for preventing or treating skin ageing.
A 2026 umbrella review of systematic reviews found more favourable overall evidence for collagen supplementation and reported benefits across several skin and musculoskeletal outcomes, but also noted variation between studies and the need to interpret the evidence carefully.
So, where does that leave someone taking a GLP-1 medicine?
Collagen supplements is a reasonable step, but they should be viewed as an optional addition to a nutritious diet rather than a guaranteed solution for facial volume loss.
They cannot fully replace lost facial fat but it can help with skin fullness and potentially, for some people, helping to off-set “Ozempic face”.
Natural dietary sources of collagen
Before reaching for a supplement, it is worth considering how collagen-containing foods can fit into a healthy diet.
Collagen occurs naturally in connective tissues and animal skin. Dietary sources include:
Fish skin
Chicken skin
Slow-cooked cuts of meat containing connective tissue
Gelatine
Bone broth made from bones and connective tissues
However, there is an important distinction between eating collagen and having collagen deposited directly into the skin.
When you eat collagen, your digestive system breaks the protein down into amino acids and smaller peptides. Your body then uses these building blocks according to its needs.
In other words, eating bone broth does not mean that the collagen simply travels to your face and fills in wrinkles.
There is also no need to eat large quantities of fatty or calorie-dense collagen-containing foods when trying to lose weight. Chicken skin and fatty cuts of meat, for example, can add significant amounts of energy and saturated fat.
For someone taking a weight-loss medicine, the better approach is to include collagen-containing foods where they naturally fit into a balanced diet rather than treating them as a special “anti-Ozempic face” food.
Don't forget the nutrients needed to make collagen
Your body does not simply need collagen from food. It also needs the raw materials and micronutrients involved in collagen production.
Vitamin C
Vitamin C is particularly important because it is required for collagen biosynthesis.
Good food sources include:
Peppers
Strawberries
Kiwi fruit
Oranges and other citrus fruit
Broccoli
Tomatoes
Potatoes
Combining a protein-rich meal with vegetables or fruit is therefore a simple way of supporting overall nutritional intake.
For example, grilled salmon with broccoli and potatoes, or chicken with peppers and a mixed salad, provides a much broader range of nutrients than relying on a collagen supplement alone.
Zinc
Zinc contributes to normal cell function and wound healing. Good dietary sources include meat, shellfish, dairy foods, bread and cereal products. Nnhs.uk
There is usually no need to take high-dose zinc supplements if you are eating a varied diet. Excessive zinc intake can interfere with copper absorption, so more is not necessarily better.
Copper
Copper is another mineral involved in normal connective-tissue function. Sources include nuts, shellfish and offal. The NHS notes that most people should be able to obtain the copper they need from a varied diet.
This is a good example of why a food-first approach is generally preferable to taking multiple high-dose supplements.
Which supplements might be worth considering?
There is no supplement specifically proven to reverse “Ozempic face”.
That said, supplements may have a role when dietary intake is inadequate or a deficiency has been identified.
Collagen peptides
Potentially useful for some people, but evidence for improving skin elasticity and hydration is mixed. They should be regarded as an optional supplement rather than essential treatment.
Vitamin C
Usually best obtained through fruit and vegetables. Supplementation may be appropriate where dietary intake is poor or a healthcare professional recommends it, but taking very large doses does not necessarily produce better skin.
Vitamin D
Vitamin D is important for general health, but it should not be promoted as a specific treatment for facial volume loss. People in the UK may be advised to consider vitamin D supplementation, particularly during autumn and winter, depending on individual circumstances.
A general multivitamin
A multivitamin may be considered if your diet has become particularly restricted because of reduced appetite, but it should not be used as a substitute for eating a varied diet.
Anyone taking prescription medicines should tell their doctor, nurse or pharmacist about supplements they are using. The NHS specifically advises people taking semaglutide to check medicines, herbal remedies, vitamins and supplements with a healthcare professional.
What should you eat while taking GLP-1 medication?
When appetite is reduced, every meal becomes an opportunity to provide useful nutrition.
A simple way to structure meals is to prioritise:
Protein first: eggs, Greek yoghurt, cottage cheese, fish, chicken, lean meat, tofu, beans or lentils.
Vegetables and fruit: particularly colourful varieties providing vitamin C and other micronutrients.
High-fibre carbohydrates: potatoes, oats, wholegrain bread, brown rice and wholegrain pasta, according to your individual energy requirements.
Healthy fats: small amounts of nuts, seeds, olive oil and oily fish.
The NHS Eatwell Guide recommends eating a variety of foods across the major food groups, including fruit and vegetables, higher-fibre starchy foods, protein foods and dairy or alternatives.
If your appetite is very small, speak to your clinic rather than simply accepting that you can barely eat. Your healthcare team can help you find practical ways to meet your nutritional needs while continuing to lose weight safely.
Resistance training matters too
Although this article focuses on facial changes, preserving muscle elsewhere in the body is an important part of healthy weight loss.
Research increasingly supports combining weight-loss medication with resistance exercise and adequate protein rather than relying on medication and calorie restriction alone. A recent meta-analysis found that resistance training alongside lifestyle intervention was associated with a more favourable pattern of lean-mass preservation.
Strength training can include weights, resistance bands, gym machines or appropriately progressed bodyweight exercises.
It will not prevent facial fat loss, but it can help improve overall body composition and physical function during weight loss.
What about hydration?
Adequate hydration is another simple but important part of looking after yourself during weight loss.
The NHS recommends that most adults aim for around six to eight glasses or cups of fluid a day, although individual needs vary according to factors such as activity, temperature and health.
If nausea, vomiting or diarrhoea is making it difficult to drink enough, contact your healthcare team.
Good hydration will not replace lost facial volume, but dehydration can contribute to feeling unwell and may make skin appear temporarily less plump.
Can facial volume return?
This varies considerably from person to person.
If facial fullness has reduced because of weight loss, some of the appearance may change if weight stabilises or if there is some subsequent weight regain. However, deliberately regaining weight simply to restore facial volume would generally not be an appropriate strategy when the purpose of treatment is to improve health.
For people who remain concerned about facial volume, skin laxity or ageing, a consultation with a suitably qualified dermatologist or aesthetic medical professional may be appropriate.
It is important to distinguish nutritional support from cosmetic treatment. Supplements and dietary changes cannot reliably replace lost facial volume. Treatments such as dermal fillers or collagen-stimulating procedures are separate medical or aesthetic interventions and should be discussed with an appropriately qualified practitioner.
The bigger picture: focus on healthy weight loss, not just the scales
Perhaps the most important message for anyone experiencing “Ozempic face” is that facial changes do not mean your weight-loss treatment is failing.
In many cases, facial volume loss is simply evidence that your body is losing fat.
Rather than trying to stop all changes to your appearance, the focus should be on achieving healthy, sustainable weight loss while protecting nutrition, muscle mass and overall wellbeing.
That means:
Don't forget the nutrients needed to make collagen
Good food sources include:
Eating enough protein
Choosing a varied, nutrient-dense diet
Including plenty of fruit and vegetables
Getting enough fluids
Undertaking resistance exercise
Avoiding unnecessarily restrictive diets
Taking supplements only where there is a sensible reason for doing so
Working with your weight-loss clinic if appetite becomes extremely low
Discussing persistent nausea, vomiting or other troublesome side effects with your healthcare team
The bottom line
“Ozempic face” is a popular term for facial changes that can occur following significant weight loss. It is primarily associated with loss of facial fat and changes in the way the skin and underlying tissues sit, rather than evidence that GLP-1 medicines are directly damaging the face.
There is currently no supplement proven to prevent or reverse facial volume loss caused by weight loss.
Collagen supplements may have some benefits for measures such as skin hydration and elasticity, although the evidence remains mixed. If you choose to use one, it should complement — rather than replace — a nutritious diet.
Natural collagen-containing foods such as fish skin, gelatine, slow-cooked connective tissue and bone broth can form part of a balanced diet, but there is no need to consume large quantities of them. More importantly, make sure your diet supplies sufficient protein alongside nutrients involved in normal collagen production, particularly vitamin C, zinc and copper.
For people using GLP-1 or related weight-loss medicines, the most effective strategy is a broader one: lose excess weight safely, nourish your body well, preserve muscle, stay hydrated and give your skin time to adapt.
If you are concerned about changes to your face, your weight-loss clinic can help assess your nutrition, rate of weight loss and overall treatment plan. And remember: successful weight management is about much more than how your face looks. The long-term improvements in metabolic health, mobility, confidence and quality of life are the real goal.
