Profhilo vs Polynucleotides vs Sculptra: Which Injectable Does What?

Last updated: 2 November 2026

Three injectables are asked about more than any others at my clinic in Hale, usually in the same sentence: "Should I have Profhilo, polynucleotides or Sculptra?" They are often lumped together as "skin boosters" or "regenerative treatments", which is where the confusion starts, because they work in different layers of the face and solve different problems. One hydrates, one repairs, one rebuilds. This is a short guide to which does what, which suits which concern, and how I choose between them, with the honest state of the evidence for each.

In this article:

• What is the difference in one sentence?
• Which treatment for which concern?
• How do the courses, results and evidence compare?

What is the difference in one sentence?

Treatment	What it is	What it does, in one sentence
Profhilo	Pure, high concentration hyaluronic acid with no cross linking, injected at five points each side of the face where it spreads through the tissue	Hydrates: deeply moisturises the skin from within and improves elasticity and glow for dry, dull, crepey skin
Polynucleotides	Highly purified DNA fragments from salmon or trout, injected in a grid of tiny shallow injections or by cannula	Repairs: signals the skin's own cells to calm inflammation and make more collagen, for thin, reactive, tired skin and the under eyes
Sculptra	Poly L lactic acid microparticles in suspension, placed deeper in the fat layer by cannula	Rebuilds: stimulates new structural collagen over months to restore support where the face has lost volume and begun to sag

The simplest way to remember it: Profhilo is for the surface, polynucleotides are for the skin, Sculptra is for the scaffolding. None of them is a filler; none adds immediate volume to a lip or a cheekbone. If what you want is a sharper contour today, that is a dermal filler conversation.

Which treatment for which concern?

This is the table I draw in consultations. Find your main concern, and the right starting point is usually obvious.

Your main concern	Best fit	Why
Dry, dull, "nothing moisturises it" skin	Profhilo	Hyaluronic acid binds water in the dermis; the glow is visible within weeks
Fine crepey lines on cheeks, neck or chest	Profhilo first; polynucleotides if skin is also thin or reactive	Hydration plumps crepiness quickly; repair helps when the skin itself is fragile
Tired, dark, crepey under eyes	Polynucleotides	The area with the best polynucleotide evidence, and the reason I do not offer tear trough filler
Sensitive, red prone or menopausal skin that reacts to everything	Polynucleotides	Calming and barrier supporting rather than just hydrating; see polynucleotides for menopausal skin
Acne scarring, texture, enlarged pores	Polynucleotides, usually with microneedling	Repair signals plus controlled injury remodel texture
Flat cheeks, hollow temples, a face that looks "deflated"	Sculptra	The only one of the three that rebuilds structural support where fat and bone have receded
Early jowls, softening jawline, sagging	Sculptra, sometimes with Radiesse	Lift comes from support above, not from treating the skin; see jowls treatment
Volume loss after Mounjaro or rapid weight loss	Sculptra first, then skin quality treatment on top	Structure before surface; see Sculptra for Mounjaro face
"I just want to look well, with nothing obvious"	Any of the three, chosen by age and skin	None adds shape, so none can look overdone; this is their shared appeal

Takeaway: ask which layer your concern lives in. Dehydrated surface: Profhilo. Thin, reactive, tired skin: polynucleotides. Lost support and early sagging: Sculptra.

How do the courses, results and evidence compare?

Treatment	Course and when you see results	How long it lasts, and the evidence
Profhilo	Two sessions a month apart; glow from two to four weeks after the first, peak about a month after the second. Ten injection points, five minutes, small bumps for a few hours	Around six months, then a single maintenance session. Good evidence for hydration and elasticity measured by skin instruments; it does not build structural collagen in a way that lifts
Polynucleotides	Three sessions three to four weeks apart (£255 each on the introductory course, £295 for maintenance); texture and glow from two to four weeks, firmness building to three months after the course. Blebs and redness for 12 to 48 hours	Maintenance two or three times a year. Evidence is real but still small: trials of up to 120 people show better wrinkles and elasticity, particularly around the eyes, and a 2024 review called the overall evidence limited
Sculptra	Two or three sessions six to eight weeks apart by cannula with local anaesthetic; little to see for the first month, then gradual change over three to six months as collagen builds. Five days of home massage after each session	Up to two years, then a single top up. The longest track record of the three, with biopsy proven new collagen and over two decades of use; the slowest to show and the most durable

"There is limited high-quality evidence available on the use of polynucleotides in aesthetic medicine. Further research is needed to confirm their efficacy and optimal use in different indications." Lee KWA, Yi KH et al., International Journal of Molecular Sciences, 2024.

I include that quote because it is the honest ranking of the evidence: Sculptra has the deepest data, Profhilo has good instrument measured data for hydration, and polynucleotides are promising with trials still catching up. All three have excellent safety records, and in my experience all three do what the table says when they are matched to the right concern. The mismatches are where disappointment comes from: Profhilo for jowls, Sculptra for dullness, polynucleotides for a hollow cheek.

Can you combine them?

Yes, and the best plans for faces over 40 often do, because most of us have a problem in more than one layer. The rule is structure first, skin second.

Combination	Who it suits	How I sequence it
Sculptra then polynucleotides	Volume loss plus thin, tired skin; the commonest menopausal and post weight loss picture	Sculptra course first, polynucleotides from about four weeks after the last session once the massage phase is over
Polynucleotides then Profhilo	Reactive skin that is also dehydrated	Repair first, then hydrate; or alternate them through the year. I explain this in why I combine polynucleotides with skin boosters
Any of them with anti wrinkle injections or filler	Most people; they address movement and contour, which none of the three do	Usually two weeks apart; see can you and should you combine aesthetic treatments
All three at once	Almost nobody	Start with the layer that bothers you most, judge the result, then decide; skin often needs less than people expect once support is restored

At a consultation at my clinic in Hale I look at the face in layers, from bone and fat up to the surface, and tell you which layer your concern lives in. Sometimes that means one of these three, sometimes a different treatment, sometimes a prescription retinoid and patience. The one thing I will not do is prescribe a "skin booster" because it is the one you have heard of. If you are still not sure which concern you have, which treatment do I need? walks through every concern and its options.

Frequently asked questions

Is Profhilo or polynucleotides better?

Neither; they do different jobs. Profhilo for dry, dull skin that needs hydration and bounce; polynucleotides for thin, reactive, tired skin and the under eye area, where they have the best evidence.

Is Sculptra better than Profhilo for sagging?

Yes. Profhilo improves skin quality but does not rebuild support. Sagging and early jowls come from lost volume in the deeper layers, which is what Sculptra addresses over several months.

Which lasts longest?

Sculptra, at up to two years after a course. Profhilo lasts around six months, polynucleotides need maintenance two or three times a year.

Which works fastest?

Profhilo, with a visible glow within weeks. Polynucleotides build over one to three months, Sculptra over three to six.

Can polynucleotides replace tear trough filler?

They treat a different problem. Filler adds volume under the eye, which I do not offer because of the poor satisfaction rate; polynucleotides improve the thin, crepey, dark skin that causes most under eye complaints.

Which should I start with in my forties?

If your skin looks tired and thin, polynucleotides. If it is dry and dull, Profhilo. If your face looks flatter or heavier than it did, Sculptra. A consultation settles it in ten minutes.
