Profhilo vs Fillers: Skin Quality or Volume — Which Do You Need?

Profhilo gets described as “an injectable” and filed mentally alongside filler, which is where most of the confusion starts. They’re both hyaluronic acid, both come in a syringe, and both are injected into your face. After that the similarities run out.

One is doing structural work. The other is doing skin work. Booking the one that matches the wrong concern is why people occasionally finish a course feeling that not much happened — not because the treatment failed, but because it was never the treatment for that problem.

The quick answer

Fillers add. Profhilo improves.

A dermal filler is a cross-linked hyaluronic-acid gel placed in a specific spot to stay there and hold a shape — a flatter cheek, a soft jawline, thin lips. You can see the difference the moment it goes in, and it typically lasts six to eighteen months depending on the product and the area.

Profhilo is not cross-linked into a firm gel and is not placed to hold a shape. It spreads through the tissue, hydrating the skin and prompting it to behave a little more like younger skin. Nothing is contoured; the skin itself gets better. It runs as a course of two sessions about four weeks apart, and the result lasts roughly six months.

So the shortcut is: if your complaint is a shape — something has gone flat, hollow, thin or undefined — that’s filler. If your complaint is a surface — dull, crepey, dehydrated, loss of bounce — that’s Profhilo or another skin booster.

Profhilo vs dermal fillers: side by side

What Profhilo actually does

Most fillers are cross-linked: the hyaluronic acid is chemically bonded into a firm, cohesive gel so that it resists being squashed and holds its position. That is exactly what you want when you are rebuilding a cheek. It is exactly what you do not want when the goal is to treat a whole area of skin.

Profhilo takes a different route. It combines high and low molecular weight hyaluronic acid, stabilised by a patented thermal process rather than a chemical cross-linking agent, at a high concentration — 32 mg of each, 64 mg of hyaluronic acid in a 2 ml syringe. Because it isn’t locked into a stiff gel it stays fluid and diffuses through the tissue, which is why it treats an area rather than a point.

The laboratory work behind it, published in PLOS ONE, found that these hybrid complexes increased the expression of type I and type III collagen and of elastin in skin cells well beyond what either weight of hyaluronic acid managed alone. Worth being precise about what that is: cell and skin-model evidence for the mechanism, not a promise about your face. What it supports is the clinical observation that skin treated this way behaves more elastically — which is what clients actually describe, usually as “bouncier” rather than “fuller”.

Two practical consequences. First, it is injected into a fixed pattern of defined points chosen to spread the product safely and evenly, not wherever a line happens to be — so it is not a treatment you can have “just a bit of” in one spot. Second, it is genuinely a course. Two sessions about four weeks apart is the standard protocol, and results build gradually over the weeks that follow rather than appearing on the way out of the studio.

It is also used well beyond the face — the neck, décolletage and backs of the hands are all areas where the skin is thin, ages visibly and has no shape to restore, which makes them a natural fit.

Profhilo isn’t the only skin booster

Profhilo is the name people know, but it sits in a family of injectable skin treatments, and it isn’t automatically the right one. At Lady Young’s the injectable skin booster menu also includes polynucleotides, which are used for skin quality and repair and come as a short course, with a lighter dedicated version for the delicate under-eye area. Hyaluronic-acid boosters such as Seventy Hyal and LumiPro are a smaller, lower-cost step for hydration and glow, and PDO mono threads sit slightly apart again as a collagen-stimulating option.

The honest position on the newer members of this family is that they are promising and widely used, with an evidence base that is younger and thinner than the one behind hyaluronic acid. That is a reason for a practitioner to be measured about what they promise, not a reason to avoid them — but you should expect measured, and be wary of anyone describing any of these as transformative.

These also pair naturally with what you do to your skin from the outside. The facials and skin treatments page covers microneedling, peels, dermaplaning and PRP, which work on texture and tone from a different direction and are often the better first step if your skin has never had a proper course of anything.

What dermal fillers actually do

Fillers replace volume you have lost or build structure you never had. Facial ageing isn’t only a skin story: the fat pads of the mid-face shrink and shift and the bone underneath remodels, which is what drags the lower face down and deepens the folds either side of the mouth. No amount of skin quality treatment fixes a structural change of that kind, because there is nothing wrong with the skin — there is less underneath it.

Our dermal fillers page covers every area treated, with dedicated pages for cheek filler and jawline filler, and a separate page for lip fillers, where the concern is usually shape rather than ageing. The trade-off against Profhilo is straightforward: filler shows immediately and lasts longer, but there is more short-term swelling, a real chance of small bruises, and a result that has to be judged rather than simply applied. The reassurance is that hyaluronic-acid filler is dissolvable if something isn’t right.

And if what is bothering you only appears when your face moves, neither of these is your answer — anti-wrinkle injections vs fillers works through that decision, and anti-wrinkle injections are the treatment for expression lines.

Which one fits your concern?

• “My skin looks dull and tired however much I sleep.” Skin quality — Profhilo or another booster.
• “My skin has gone crepey, especially on my cheeks.” Profhilo.
• “My neck and chest have aged faster than my face.” Profhilo — thin skin, no shape to rebuild.
• “The backs of my hands give my age away.” Profhilo.
• “My cheeks look flat and everything sits lower.” Volume loss — cheek filler.
• “My jawline has softened and blurred.” Jawline filler.
• “Dark hollows under my eyes.”Usually tear-trough filler, sometimes under-eye polynucleotides if the skin quality is the issue rather than the hollow — a delicate area that always needs assessing in person.
• “My lips have thinned.” Lip filler. If it is the colour rather than the volume, read lip blush vs lip filler.
• “I want to look well, not different.”This is the sentence that most often ends in Profhilo — it is the treatment that changes nothing about your shape.

Can you have both?

Yes, and for a lot of faces the combination makes more sense than either on its own. They aren’t competing for the same job: filler rebuilds the architecture, Profhilo improves the surface stretched over it. Good structure under poor-quality skin still reads as tired, and beautiful skin over a deflated mid-face still reads as tired.

They are not usually done in the same sitting, though. The sensible approach is to treat one thing, let it settle, then reassess — partly because it is easier to judge what is still needed, and partly because it spreads the cost. Very often the reassessment shows the second treatment can be smaller than planned, or isn’t needed at all yet.

Safina would far rather stage treatment and do less than book you in for everything at once. If a course of skin boosters would serve you better than the syringe of filler you came in asking about, she’ll say so — that conversation is the point of a consultation.

What each costs at Lady Young’s

Profhilo is priced as the course it is designed to be: the standard two treatments, four weeks apart, is £380, or £200for a single session — useful as a maintenance top-up rather than as a first course. Because a completed course lasts around six months, most people are looking at repeating it once or twice a year.

The other skin boosters sit lower: polynucleotides £200 for a course of two on the face, neck or body, under-eye polynucleotide boosters £130, and the Seventy Hyal and LumiPro hyaluronic-acid boosters £130 each. PDO mono threads start at £170.

Dermal fillers are priced by area: chin filler £160, cheek filler from £230, jawline filler from £250, tear trough £225, and lip filler from £115 for a 0.6ml refresh. More per appointment than a booster, but six to eighteen months between them.

If skin quality is what you are really after, the clinic’s Boost & Revive package — face and neck boosters plus a choice of lip or under-eye booster — is £300. Every price is confirmed at your consultation, and the full menu sits on the aesthetics treatments hub.

Before you book anyone

Injectable skin boosters are marketed hard, and the marketing tends to be much more confident than the evidence. Two things are worth holding on to.

First, be sceptical of before-and-after photos for any treatment that works on skin quality. Lighting, makeup and camera angle move that kind of result far more than they move a jawline. Ask instead what the treatment can realistically change, over what timescale, and what it will not touch — a practitioner who answers that list plainly is telling you something useful.

Second, the NHS is direct about how to choose whoever injects you: check that they are on a register accredited by the Professional Standards Authority, such as the Joint Council for Cosmetic Practitioners or Save Face, and ask what training and experience they have and what the insurance arrangements are. It specifically warns against practitioners who have only done a short training course, because filler complications can be serious — including infection, nerve damage and blindness. That advice applies wherever you go, not just here.

Safina has 16 years in the industry, holds a Level 5 Ofqual qualification in aesthetics and is fully insured, and every treatment at the clinic is carried out by her personally — you can read more about her training and approach.

Still not sure whether your skin needs rebuilding or reconditioning? That is exactly what a consultation is for. Bring the concern, and Safina will tell you which of these actually addresses it — including when the answer is a course of facials and better sun protection rather than an injectable at all.
