Medical information notice

This article compares treatment options in general terms. It is for education and does not constitute medical advice or a recommendation for you specifically. Individual outcomes vary, no result is guaranteed, and suitability for any treatment is decided only after a consultation and full clinical assessment. For advice on your own situation, book a consultation with Arman Zaki, GMC-registered Physician Associate (Ref A8131967), or message the clinic.

If you have lost weight on Mounjaro, Ozempic or Wegovy and your face has changed, the internet has one answer for you: filler. It is the loudest answer, and for one of the three things that happen to a post-GLP-1 face it is the right one. For the other two, it does very little.

My longer piece on the three changes nobody warned you about explains what is actually happening: rapid weight loss removes facial volume, it accelerates skin laxity, and it shifts the proportion between the upper, middle and lower face. This piece is the other half. It compares the treatments, and it maps each one to the change it treats, so you can walk into a consultation knowing which question to ask.

The short version. Filler replaces volume. Polynucleotides and biostimulators rebuild skin quality and firmness. Skin boosters add hydration and glow. Most natural-looking results after significant weight loss use more than one of these, sequenced over months, not all bought in a single appointment. Which mix is right for you is a consultation decision, not a menu choice.

The options at a glance

Read the table across. The column that matters most is the one people skip: what each treatment does not do.

Treatment options for post-GLP-1 facial change. Suitability, dose and course are assessed in consultation.
Treatment What it targets How it works What it does not do Who delivers it at Melatone
Dermal filler Lost volume in the cheek and temple hollows Hyaluronic acid gel replaces structural volume in a single appointment, with the result settling over two to six weeks Does not rebuild skin elasticity or correct proportion; over-use creates a heavy, over-projected look Aesthetic injector, Rhianna Beckford (Paramedic)
Polynucleotides Skin quality, elasticity and hydration Purified DNA fragments prompt fibroblast activity and collagen over a course, typically three sessions across several weeks Does not replace lost volume; results build over months rather than days Arman Zaki, clinician-led
Skin boosters Hydration, surface glow and fine lines Micro-deposits of stabilised hyaluronic acid draw water into the dermis to improve skin quality Does not lift structural volume or change facial proportion Assessed in consultation, clinician or injector
Biostimulators Gradual collagen and skin firmness Stimulate the skin to build its own collagen over weeks, for a slow and subtle firming effect Does not give an instant volume result; needs a course and patience Aesthetic injector, Rhianna Beckford (Paramedic)
Microneedling, PRP, HydroMED Pro Texture, tone and elasticity, as part of a plan Controlled micro-injury or hydro-resurfacing prompts the skin to remodel and refresh over a course Does not replace volume; works best alongside other steps, not as a standalone fix Arman Zaki, clinician-led

Filler: what it fixes, and what it does not

Filler is the fastest route to one specific change: lost midface volume. Hyaluronic acid placed in the cheek and temple can rebuild the projection that rapid weight loss flattened, and it does so in a single appointment. That is a genuine strength, and it is why filler dominates the conversation.

Its limit is just as important. Filler sits under the skin and pushes it outward. It does not tighten the skin envelope, and it does not restore proportion. A face treated with filler alone can still look loose across the jawline, because the change there is skin quality, not volume. When the only tool is filler, the temptation is to add more of it to chase a result it was never going to deliver, and that is how the over-filled look is built one appointment at a time.

Polynucleotides: skin quality, not volume

Polynucleotides are the treatment I most often reach for first after weight loss, because skin quality is the change that filler cannot touch. They work over a course, prompting the skin to rebuild the collagen and elasticity that came off with the weight. The trade-off is time: you are working on a three to six month clock, not a two week one.

If you are weighing these two directly, I have written a dedicated comparison of polynucleotides and filler, and when each one makes sense. The short answer is that they are not rivals. They treat different changes and are often sequenced together.

Skin boosters: hydration and glow

Skin boosters are the gentlest option here. Small deposits of stabilised hyaluronic acid draw water into the dermis, improving hydration, light reflection and the look of fine lines. They are a quality-of-skin treatment, not a structural one. For someone whose main complaint is that the skin looks dull or crepey rather than hollow, boosters can be the right first step. They will not, on their own, address volume loss or proportion.

Biostimulators: gradual collagen, gradual result

Biostimulators sit between skin boosters and filler. Rather than adding volume directly, they prompt the skin to build its own collagen over weeks, for a firming that arrives slowly. Compared side by side with filler, the difference is speed and character: filler is immediate and structural, a biostimulator is gradual and diffuse. If you want to understand where a bio-remodeller fits against traditional filler, our Profhilo versus dermal filler comparison covers it in detail.

How a clinician sequences these across a plan

The reason none of these treatments is a complete answer on its own is that the three changes resolve on three different timelines. Skin quality needs months of regenerative work. Volume can be restored in an appointment. Proportion is best judged last, once the rest of the face has settled, so the correction is made on the face you actually have rather than the one that was still changing.

That is why we sequence, rather than sell a single session. The full structure, phase by phase, with pricing and the clinician handover, is set out on the Post-GLP-1 Recovery Programme page. If you have already read our polynucleotides versus skin boosters comparison, you will recognise the same principle applied to the skin-quality phase.

What we do not do

We do not promise a specific outcome, and we do not run before-and-after sets that imply one treatment produced a full-face, twelve-month result. Most of our patients decline photography, and we respect that.

We do not start active treatment while you are still actively losing weight. We prefer to wait until your weight has been stable for at least four weeks, so we are not treating a moving target.

Injectable work, filler and biostimulators, is delivered by our aesthetic injector, Rhianna Beckford (Paramedic). I lead the regenerative and skin-quality phases, polynucleotides, PRP and microneedling, and the proportion assessment. Keeping the plan in a small number of hands is how the face is read consistently from the first session to the last.

How to think about cost

The cheapest-looking option is rarely the cheapest in the end. A single, mistimed filler appointment that later has to be partly dissolved and redone costs more than starting with the right step for your face. If you only make one decision before you book, make it this: are you paying for a quick fix to one change, or a plan that addresses all three over time? Both are valid. They cost differently, and they age differently.

Common questions

Choosing between the options.

Is filler or polynucleotides better for Ozempic face?

Neither is better in isolation, because they treat different changes. Filler replaces lost midface volume in the cheek and temple hollows. Polynucleotides work on skin quality and elasticity, the part that rapid weight loss thins out. Many people who want a natural result need an element of both, sequenced over months. Which one to start with, and whether you need the other, is decided in a consultation after your weight has been stable for about four weeks.

Can you fix Mounjaro face without filler?

Partly, and it depends on which change bothers you most. If the main concern is loose or crepey skin and lost firmness, regenerative options like polynucleotides, biostimulators and microneedling improve skin quality over three to six months without any filler. If the main concern is hollowing and lost structural volume, that specific change responds best to filler. A consultation maps your face to the right mix.

How long do post-GLP-1 face treatments last?

It varies by treatment and by person. Hyaluronic acid filler typically lasts several months to over a year before a top-up is considered. Regenerative results from polynucleotides and biostimulators build over three to six months and are maintained with periodic courses rather than a one-off. Your consultation gives a realistic timeline for your plan; no result is permanent and none is guaranteed.

Do I need to stop Mounjaro or Ozempic before treatment?

That is a decision for you and the GP or specialist who prescribed the medication, not for us. We are not in the prescribing loop. We assess and treat the face after the medical decisions have been made, and we prefer to begin once your weight has been stable for at least four weeks so we are not chasing a moving target.

Which treatment helps skin laxity after weight loss?

Skin elasticity responds to regenerative treatment rather than to filler. Polynucleotides, biostimulators and microneedling with PRP prompt the skin to rebuild collagen over months. Filler replaces volume underneath the skin but does not tighten the skin envelope itself, which is why a face treated with filler alone can still look loose.

Are these treatments suitable for darker skin tones?

They can be, with melanin-aware delivery. The regenerative and resurfacing steps such as polynucleotides, microneedling and peels are selected and dosed with your Fitzpatrick type in mind to reduce the risk of post-inflammatory pigmentation. Suitability is always assessed in a consultation first. Melatone works with skin of colour as a core focus rather than an afterthought.
