When beauty journalist Anne Maylor tried Profhilo, she was not hoping for larger lips or sharper cheekbones. Her concern was simpler. Her skin felt dry and had started to look dull.

The injections caused a short sting. The next day, she noticed mild tenderness and a small lump near her cheekbone. Both settled quickly. The result took longer to appear.

About a week after her first session, she felt that her skin was less dry. By the time she returned for a second treatment, her face looked brighter. Family members and a colleague told her that she looked fresher.

Nothing about her facial shape had changed. Her cheeks were not larger. Her jaw was not more defined. Her skin simply looked healthier.

That published experience captures the purpose of Profhilo well. It contains hyaluronic acid, just like many dermal fillers, but it is not mainly designed to build volume. Its role is to improve skin hydration, texture, elasticity, and mild looseness.

This difference matters because patients often book the treatment with the wrong expectations. Profhilo may improve the condition of the skin. It will not reshape the face in the way a traditional filler can.

What Is Profhilo?

Profhilo is an injectable product made from high and low molecular weight hyaluronic acid.

A standard syringe contains 64 mg of hyaluronic acid in 2 ml. Half of this is 32 mg of high molecular weight hyaluronic acid. The other half is 32 mg of low molecular weight hyaluronic acid.

Hyaluronic acid is already present in the human body. It helps tissue attract and retain water. In the skin, it contributes to hydration, softness, and flexibility.

However, the fact that Profhilo contains hyaluronic acid does not make it the same as every hyaluronic acid filler.

Many traditional fillers are chemically cross-linked. This gives them a firmer structure and helps them remain in a selected area after injection. A doctor can use that structure to support a cheek, fill a deep fold, or change the shape of the lips.

Profhilo is produced through a thermal process called NAHYCO technology. The product does not rely on conventional chemical cross-linking agents to create its structure. It has relatively low viscosity, which allows it to spread more widely through the tissue.

This spreading behaviour is central to what Profhilo does. It is not placed to form a new contour. It is placed to influence the quality of the surrounding skin.

Why Profhilo Is Not a Traditional Filler

The word “filler” normally describes a product that fills space or adds support.

A person may choose filler because ageing has caused volume loss in the cheeks or temples. Someone else may want to improve the shape of the chin or lips. In these cases, the doctor places the product in a precise location because the product needs to remain there.

Profhilo has a different purpose.

Its fluid structure allows it to distribute across a wider area. Instead of building a single facial feature, it is intended to improve hydration and support gradual changes in the skin.

A useful way to think about the difference is to focus on the problem being treated.

If the main issue is lost facial volume, Profhilo is unlikely to replace a structural filler. If the main issue is dry, thin, crepey, or mildly loose skin, Profhilo may be more relevant.

It would still be inaccurate to say that Profhilo creates no fullness at all. Any liquid placed beneath the skin may cause temporary swelling. The important point is that standard Profhilo is not designed as a targeted volume-building treatment.

Patients may also come across the name Profhilo Structura. This is a separate product designed for deeper tissue concerns and facial volume loss. A 2024 clinical study involving 50 participants examined Profhilo Structura for facial volume loss and skin laxity. Standard Profhilo and Profhilo Structura should not be treated as the same procedure.

What Profhilo Does After Injection

Profhilo mainly aims to improve the skin through hydration and tissue remodelling.

The hydration effect is the most direct. Hyaluronic acid binds water. When Profhilo is injected, it may increase moisture in the treated tissue. Better-hydrated skin often looks smoother and feels softer.

This may reduce the appearance of fine dehydration lines. It can also make thin or crepey skin appear fresher.

The second effect is more complex. Research suggests that hybrid high and low molecular weight hyaluronic acid complexes can interact with cells involved in tissue structure and repair. These include fibroblasts and keratinocytes.

Fibroblasts help produce collagen and elastin. Collagen gives skin strength. Elastin allows skin to stretch and return to shape. Both tend to decrease with age.

This is why Profhilo is often described as a bio-remodelling treatment. The goal is not only to place moisture in the skin. It is also to support biological activity connected with skin quality.

That claim needs to be kept in perspective. Laboratory findings do not mean every patient will experience a visible lift. Skin biology is affected by age, hormones, sun exposure, smoking, genetics, and general health.

In practice, Profhilo tends to produce a subtle result. The skin may look better hydrated. Texture may appear smoother. Mild laxity may improve. Fine lines caused partly by dryness may look softer.

It does not pull heavy tissue upward. It does not recreate lost bone support. It cannot provide the effect of a surgical facelift.

What the Current Research Shows

After hours of research, the fairest conclusion is that Profhilo has encouraging evidence, but the total body of research remains limited.

The 2026 Systematic Review of the Efficacy and Safety of Profhilo examined nine studies involving 278 participants. It looked at changes in hydration, elasticity, skin density, wrinkles, laxity, and facial volume loss. The review reported improvements or positive trends across several of these measures.

The same review found that reported adverse effects were generally mild and short-lived. These included bruising, swelling, local discomfort, and small raised bumps.

Still, 278 participants across nine studies is not a large evidence base.

The studies also differed from one another. Some examined the face. Others focused on the neck or body. They used different methods to measure results and followed patients for different lengths of time.

Some studies did not include an untreated control group. Others relied partly on patient satisfaction. Several papers also involved manufacturer funding, medical writing support, or authors with industry links.

These details do not automatically make the research invalid. They do mean the findings should be read carefully.

The evidence supports Profhilo as a treatment that may improve skin quality. It does not prove that every patient will see a clear change or that Profhilo works better than every other injectable skin treatment.

What the Neck Study Found

One of the most relevant clinical studies examined loose and rough neck skin.

The 2022 Efficacy and Tolerability of Hybrid Complexes Study included 25 adults aged 40 to 65. Each participant had mild to moderate neck roughness and laxity.

They received two treatments at 30-day intervals. Researchers assessed their skin one month and four months after the first treatment. The assessments included photographs, clinical scoring, patient feedback, and instrument-based measurements.

The study reported statistically significant improvements in neck roughness and laxity. The benefit seen after the first session continued to develop by the later assessment.

This is useful because the neck is often difficult to treat. The skin is thin and tends to become crepey as collagen, elasticity, and moisture decline.

However, the study involved only 25 participants. It did not include a large untreated comparison group. The results suggest that Profhilo may help suitable patients, but they cannot predict an individual result.

What the Facial Hydration Study Found

A 2025 single-centre study in Asian female patients examined changes in facial skin after Profhilo treatment.

Researchers reported improvements in superficial hydration and transepidermal water loss. Transepidermal water loss measures how much water escapes through the outer layer of the skin. It is commonly used when assessing skin-barrier function.

The treatment was also described as generally well tolerated.

However, the study itself noted that clinical research in this area remains limited. It was not a large randomised trial, and its findings should not be applied automatically to every age group, skin type, or ethnic background.

The correct conclusion is that Profhilo may improve hydration and moisture retention in some patients. It would be too strong to claim that it repairs every patient’s skin barrier.

What Results Should Patients Expect?

Profhilo is most suitable for someone who wants healthier-looking skin rather than a visibly altered face.

A patient may notice that the skin feels less dry. It may look smoother and more rested. Fine surface lines may appear softer. Mild looseness may also improve.

The result usually develops gradually rather than overnight.

Anne Maylor’s published experience is a good example. She noticed reduced dryness after about a week. Later, her skin appeared brighter, softer, and healthier. The result was noticeable enough for people close to her to comment, but it did not change her facial structure.

This kind of subtle result can be a benefit for someone who wants to look refreshed without appearing “done.” It can also disappoint a patient who expects lifted jowls or restored cheek volume.

Individual results depend on many factors. These include skin thickness, age, sun damage, smoking, hormonal changes, medical history, the area treated, and the practitioner’s technique.

The condition of the skin before treatment also matters. Profhilo cannot correct every sign of ageing with one product.

What Profhilo Cannot Do

Profhilo cannot replace major lost facial volume.

It will not create larger lips, high cheekbones, or a sharply defined jaw. It does not provide the focused structural support of a traditional filler.

It also does not reduce muscle activity. Lines caused by repeated movement, such as frown lines or some forehead lines, are different from lines caused by dehydration or skin thinning.

Profhilo cannot remove deep folds or lift severe loose skin. A person with heavy jowls may need a different non-surgical treatment or a surgical consultation.

It is also not a treatment for active acne, eczema, suspicious moles, skin cancer, or unexplained pigmentation.

The most useful consultation begins with a diagnosis of the concern rather than a request for a specific product. A doctor should first decide whether the problem is dryness, volume loss, muscle movement, pigmentation, scarring, or true tissue laxity.

Only then can the right treatment be chosen.

How the Treatment Is Usually Performed

For facial treatment, many doctors use the Bio Aesthetic Points technique.

This method commonly involves five injection points on each side of the face, giving 10 injection points in total.

Small amounts of Profhilo are placed beneath the skin. Temporary bumps may appear where the product was injected. These often settle as the product spreads.

The usual starting course consists of two sessions about 30 days apart. This schedule has been used in published studies and product protocols.

The exact plan should still be based on a medical assessment. A responsible practitioner should review medication, allergies, pregnancy, breastfeeding, skin infections, medical conditions, and previous reactions to injectable treatments.

The patient should also receive a clear explanation of the expected result. Consent is only meaningful when the limits and risks have been discussed.

Understanding Side Effects and Safety Data

Common short-term reactions include redness, tenderness, bruising, swelling, and small injection bumps.

The 2020 Safety Assessment of High- and Low-Molecular-Weight Hyaluronic Acid examined reports collected between 2015 and 2018. It identified 12 adverse-event reports, including swelling, redness, bruising, oedema, and delayed nodules. None of those reports was classified as serious.

A larger 2025 post-market safety review recorded 371 adverse-event reports for facial Profhilo. The authors calculated a reporting rate of 0.034% using the estimated number of exposed patients.

That number should not be described as the true risk of side effects.

Post-market data depend on patients and practitioners reporting reactions. Mild bruising or swelling may never be formally recorded. The total number of treated patients was also estimated.

The figure is therefore a reporting rate, not proof that only 0.034% of patients experience a reaction.

Any facial injection can cause complications. Possible problems include infection, inflammation, delayed nodules, and blood vessel injury.

Severe pain, unusual skin whitening, dark colour changes, visual symptoms, fever, or rapidly increasing swelling require urgent medical assessment.

What Belgian Patients Should Verify

Belgian law treats invasive aesthetic procedures as medical acts.

The Belgian Act of 23 May 2013 on Aesthetic Medicine and Surgery regulates non-surgical aesthetic medicine. In August 2025, the Royal Belgian Society for Plastic Surgery again stated that invasive aesthetic procedures performed by non-medical or unqualified people are illegal under Belgian law.

Before booking profhilo, patients should confirm that the injections will be performed by a licensed doctor with suitable training in anatomy and injectable treatments.

Patients should know which product is being used and how much is being injected. The packaging should be sealed, and the batch number and expiry date should be traceable.

The clinic should also explain what happens if a complication develops after the patient leaves.

Clean technique is essential because every injection creates a possible route for infection. The 2022 Standards for Aseptic Techniques in Medical Aesthetic Clinics were developed for the Benelux region to improve hygiene and reduce infection risks in aesthetic practice.

A low price does not make an injection good value if the product, practitioner, or aftercare cannot be verified.

The Best Way to Decide Whether Profhilo Is Right for You

Profhilo is neither a traditional filler nor a replacement for every other skin treatment.

It is a fluid hyaluronic acid injectable designed mainly to improve skin quality. The most realistic benefits are better hydration, smoother texture, softer fine lines, and a possible improvement in mild laxity.

The 2026 systematic review of nine studies and 278 participants supports these potential benefits. Smaller studies have also reported improvements in neck laxity and facial hydration.

The evidence also has limits. The studies are generally small. Research methods differ. Some studies lack control groups, and industry involvement appears in parts of the evidence base.

For that reason, Profhilo should not be described as a facelift in a syringe. It should not be sold as a replacement for structural filler. It should not come with a guaranteed result.

It may be a reasonable choice when the main concern is skin quality and the patient understands that the change is likely to be subtle.

For Belgian patients, the safest decision comes from an in-person assessment with a qualified doctor. The right treatment should be chosen because it matches the skin problem, not because it happens to be popular online.
