If you have started researching ways to refresh your face, you have almost certainly met two names that sound as though they should do the same thing: dermal fillers and Profhilo. Both are injected, both are based on hyaluronic acid, and both are marketed as anti-ageing treatments. Yet they work in fundamentally different ways and solve different problems — and choosing the wrong one for your concern is one of the most common (and expensive) mistakes people make. Here is a clear, impartial guide to what actually separates them.

The difference in one sentence

Dermal fillers add volume and contour to a specific place. Profhilo improves the quality of the skin itself across a broader area. One is about shape; the other is about texture, firmness and glow. Understanding that single distinction tells you most of what you need to know.

Profhilo vs dermal fillers at a glance

Dermal fillers (HA) Profhilo
What it is Cross-linked hyaluronic acid gel Non-cross-linked hyaluronic acid “bio-remodeller”
Main effect Adds physical volume and structure Stimulates collagen and elastin; improves skin quality
Best for Hollows, lost cheek or jaw definition, lips, folds Crepey, dull, lax skin; overall firmness and hydration
Does it fill a line? Yes, directly No — it works on the whole area, not a spot
How it sits in the skin Stays where placed as a gel Spreads and diffuses through the tissue
Typical protocol One session per area, topped up as needed Two sessions, four weeks apart, then maintenance
Longevity ~6–24 months (area-dependent) ~6–12 months
Reversible? Yes — dissolvable with hyaluronidase Not dissolved as a depot; naturally broken down
Typical UK cost £200–£600 per syringe/area £300–£600 per session

What dermal fillers do

Most modern dermal fillers are made from hyaluronic acid (HA), a sugar molecule that occurs naturally in your skin and holds many times its own weight in water. On its own, HA is too runny and too quickly broken down to be useful as an injectable, so manufacturers cross-link the HA chains — chemically bonding them into a stable gel. The more heavily cross-linked and firm the gel, the more structural support it gives.

That is the key to what fillers do: they are placed precisely where volume has been lost and they stay there, physically restoring shape. A softer gel might refine lip borders or soften fine lines, while a firmer, more cohesive gel rebuilds cheekbone projection or defines a jawline. Popular HA brands include Juvéderm, Restylane and Teoxane RHA. A well-planned approach — the sort of structural, whole-face thinking behind the so-called “liquid facelift” — lifts the face from deeper support points rather than simply plumping the surface.

There are also biostimulatory fillers such as Radiesse (calcium hydroxylapatite) and Sculptra (poly-L-lactic acid), which work more gradually by encouraging your own collagen. These are not reversible with hyaluronidase, which is an important thing to know before you commit. For most people, though, “dermal filler” means an HA gel that adds volume you can see immediately and that can be dissolved if needed.

What Profhilo does

Profhilo is also made of hyaluronic acid, which is why the confusion is so understandable — but it is not a filler. It is classified as a skin bio-remodeller, and the difference is in the chemistry. Profhilo uses a patented hybrid technology that combines high and low molecular weight HA without chemical cross-linking. Because it is not locked into a firm gel, it does not sit in one place as a volumising depot. Instead it spreads and diffuses through the tissue after injection.

Fillers are like scaffolding placed exactly where you need support. Profhilo is more like watering the whole lawn — it improves the condition of the skin across an area rather than propping up one point.

As it diffuses, Profhilo stimulates the skin’s fibroblasts to produce more collagen and elastin, gradually improving elasticity, hydration and firmness. The result is not a change in shape but an improvement in skin quality — the kind of crepey, dull or slightly lax skin that no amount of filler will genuinely fix. It is delivered using the BAP technique (Bio Aesthetic Points), typically five injection points on each side of the face, in a course of two sessions about four weeks apart so the effect can build. It is also widely used on the neck, décolletage and backs of the hands.

How to tell which one you need

The honest starting point is to name your actual concern, because the two treatments barely overlap:

  • Choose fillers if your issue is a defined loss of volume or structure: flatter cheeks, a receding chin, an undefined jaw, deeper nose-to-mouth folds, thinning lips or hollow under-eyes. These are shape problems, and only volume solves them.
  • Choose Profhilo if your issue is the surface — skin that looks tired, dull, dehydrated, finely crinkled or a little lax, but where you do not want to change your features. This is a quality problem, and filler cannot fix it.

This is why a proper consultation matters so much more than a price list. Increasingly, the trend across UK aesthetics has moved away from the overfilled, “done” look of a few years ago and towards natural-looking skin quality and subtle structural restoration — and Profhilo has been one of the fastest-growing treatments on the back of that shift. A trustworthy practitioner will assess your face as a whole and tell you honestly if what you want is not what you need. Some people are best served by fillers, some by Profhilo, and many by a combination — but that decision should come from your face, not from whatever the clinic is promoting that month.

Can you have both?

Yes. Because they do different jobs, fillers and Profhilo are frequently used together as part of a longer-term plan — for example, filler to restore lost cheek support and Profhilo to improve the overall condition of the skin. They are usually done at separate appointments rather than on the same day, and the sequencing is something your practitioner should plan around your priorities and budget. Combining them is common and reasonable; being sold both without a clear rationale is not.

Cost, longevity and upkeep

Neither treatment is a one-off. In the UK, dermal fillers typically cost around £200–£600 per syringe or area, with multi-area plans commonly reaching £600–£1,500 or more. Results last anywhere from about 6 months in mobile areas like the lips to 18–24 months for firmer structural work in the cheeks or jawline.

Profhilo usually costs £300–£600 per session, and because the recommended protocol is two sessions four weeks apart, a full initial course tends to run £600–£1,200. Results are generally reported to last 6–12 months, after which a single maintenance session is advised to sustain the effect. Whichever you choose, factor in the ongoing cost of upkeep rather than just the first appointment.

Safety and choosing well

Both treatments are injections, so both share the everyday risks of bruising, swelling, tenderness, and occasionally lumps or infection. The most serious filler-specific complication is vascular occlusion — filler accidentally injected into or pressing on a blood vessel, which in rare cases can cause skin damage or, in the worst instances involving certain facial areas, visual problems. This is precisely why deep knowledge of facial anatomy is non-negotiable, and why HA fillers being reversible with hyaluronidase is such a valuable safety feature.

It is also worth knowing that, in the UK, HA fillers and Profhilo are currently regulated as medical devices rather than medicines, which historically meant less scrutiny than prescription treatments. That is changing: from 2025 the government has confirmed that lip and facial dermal fillers will fall under a new local-authority licensing scheme with training, safety and insurance standards, and tighter rules are on the way. In the meantime, the responsibility to choose a safe, properly trained injector largely falls to you.

The technology matters far less than the hands holding the needle. A skilled, well-trained practitioner using the right product for the right concern is the single biggest factor in a good result.

Making an informed choice

Profhilo and dermal fillers are not rivals — they are different tools for different jobs. Fillers restore volume and structure you have lost; Profhilo improves the quality of the skin itself. The most common route to disappointment is expecting one to do the other’s work. If you can name your concern honestly — shape versus surface — you are already most of the way to the right decision.

Above all, the clinic and the practitioner matter more than the brand name on the box. Use Clinic Finder to compare accredited clinics near you, check that your injector is properly qualified and insured, and ask exactly why they are recommending one treatment over the other before you book.
