Profhilo and Skin Boosters: Injectable Skin Hydration

If your skin looks a little tired, dull or crêpey but you are not chasing plumper cheeks or a filled-in line, you may have come across the term “skin booster”. Treatments like Profhilo have become some of the fastest-growing options in UK aesthetics — Profhilo search interest alone has reportedly risen by around 340% since 2024 — as more people move away from an obviously “done” look and towards simply better-quality skin. But what actually sits behind the hype, how do these injectables differ from dermal fillers, and what can they realistically do? Here is an honest, jargon-free guide.

What are skin boosters?

Skin boosters are injectable treatments designed to improve the quality of your skin — its hydration, elasticity, firmness and glow — rather than to add shape or volume. Most are based on hyaluronic acid (HA), the same water-loving molecule your skin produces naturally, but they are formulated and delivered very differently from traditional fillers.

The category has grown to include several well-known names — Profhilo, Jalupro, Restylane Skinboosters, Teosyal Redensity and Seventy Hyal, among others. They share a common goal: hydrating and refreshing the skin from within while nudging it to make more of its own collagen and elastin. Profhilo is the best-known of the group, so it is a useful place to start.

How Profhilo works

Here is the important distinction: Profhilo is not a dermal filler — it is a skin bio-remodeller. It uses a patented hybrid technology (marketed as NAHYCO) that combines ultra-pure, non-cross-linked high molecular weight and low molecular weight hyaluronic acid in a single formulation. Because it is not cross-linked with a chemical agent, it does not sit as a firm gel depot in one place the way a filler does.

Instead, once injected, Profhilo spreads and diffuses through the tissue. As it does so, it stimulates your fibroblasts — the cells responsible for building the skin’s scaffolding. The result is increased production of collagen types I, III and IV, plus elastin, which is why the effect is described as an improvement in skin quality, elasticity and firmness rather than a plumping of any single area.

Fillers add structure to a specific spot; bio-remodellers like Profhilo work across a whole region to improve the skin itself. It is the difference between propping something up and improving its underlying condition.

Delivery is deliberately simple. Profhilo uses the BAP (Bio Aesthetic Points) technique — typically five carefully chosen injection points on each side of the face. The HA then diffuses outwards from those points, so fewer injections are needed than with treatments that must be spread across the whole area. The standard course is two sessions about four weeks apart, allowing the remodelling effect to build in stages.

What the evidence shows

Skin boosters sit within a reasonably well-studied class. A 2024 peer-reviewed study in Health Science Reports, looking at a related NAHYCO-based formulation, found statistically significant improvements in clinical scores for both fat-volume loss and wrinkle severity after the first treatment, with benefits maintained at the three-month follow-up and echoed by patients’ own assessments. Importantly, the study reported no serious adverse events, supporting the strong safety profile the product class is known for.

Supporting laboratory work has also shown that the hybrid HA complex resists enzymatic breakdown for longer than standard hyaluronic acid, which helps explain its sustained skin-quality effect. As always, study results reflect averages — your own response depends on your skin, age and lifestyle, and no treatment can guarantee a specific outcome.

Profhilo vs fillers vs other boosters

Because the terminology overlaps, it helps to see the main options side by side.

A few of the other names worth knowing:

• Jalupro blends amino acids with low-molecular-weight HA, using the amino acids as building blocks to prompt the skin’s own collagen and elastin synthesis — positioned as a biorevitaliser for fine lines and mild laxity.
• Restylane Skinboosters deliver micro-droplets of HA to improve hydration, elasticity and glow without a volumising effect.
• Teosyal Redensity combines HA with vitamins, minerals and antioxidants, and is often chosen for delicate areas such as under the eyes.

If you are weighing regenerative options specifically, our guide to polynucleotide injections explains how “salmon DNA” treatments differ from HA-based boosters, and our overview of dermal fillers for facial rejuvenation covers when adding genuine volume is the right call.

Cost, longevity and upkeep

In the UK, Profhilo typically costs around £300–£600 per session. Because the recommended protocol is two sessions four weeks apart, a full initial course usually comes to roughly £600–£1,200. Results are generally reported to last 6–12 months, after which most people book a single maintenance top-up to keep the effect going. Think of a skin booster as an ongoing part of a skincare routine rather than a one-off event.

Downtime is minimal. The most common after-effect is small, temporary bumps at the injection points, which usually settle within a day or so, along with the possibility of minor bruising or tenderness. As with any injectable, choosing a suitably qualified, insured practitioner who assesses your skin properly is the single most important safety step.

Where skin boosters fit — and where they don’t

Skin boosters are genuinely good at what they are designed for: hydration, radiance, elasticity and a smoother, healthier-looking surface. What they are not is a lifting treatment. Because they add no structural volume and apply no tightening force, they will not lift a heavier jawline, reposition sagging tissue or replace lost facial support.

If your main concern is laxity rather than skin quality, an energy-based approach is usually the better route. HIFU uses focused ultrasound to reach the deep support layer and encourage gradual firming, while radiofrequency skin tightening heats the skin to stimulate collagen and improve firmness. Many people find that pairing a skin booster for quality with a tightening treatment for structure gives the most balanced, natural result — and improving the collagen foundation can also enhance the benefits of good microneedling for facial rejuvenation.

Is a skin booster right for you?

Profhilo and its skin-booster cousins are a lovely option if you want your skin to look hydrated, fresher and more resilient without adding volume or chasing a dramatic change. What they ask of you is a little patience — this is gradual bio-remodelling across a short course, not an instant transformation — and a realistic understanding of what injectable hydration can and cannot do.

The best next step is a proper conversation. Book a consultation with our team to have your skin assessed honestly and a plan built around what will genuinely suit you — whether that is a skin-quality approach, a firming treatment such as HIFU or radiofrequency, or a thoughtful combination. We would love to help you feel like a fresher version of yourself.
