Key takeaways: Skin boosters are injectable treatments that improve skin quality — hydration, glow and elasticity — rather than adding volume like filler. Profhilo and Seventy Hyal use hyaluronic acid for deep hydration; polynucleotides go further, stimulating your skin's own repair. Most protocols need two sessions, with results building over 4–8 weeks.
If I had to name one treatment category that defines 2026, it's this one. Industry analysis confirms what I see in my diary: regenerative treatments like polynucleotides and advanced skin boosters are trending heavily for 2026, as patients prioritise skin quality and natural collagen production over added volume. Clients no longer come in pointing at a line they want filled — they come in saying "my skin just looks tired."
What are skin boosters?
Skin boosters are micro-injections placed superficially into the skin — not deep like structural filler. Instead of changing your face shape, they change your skin's condition: hydration, bounce, luminosity and fine crepiness. Most are based on hyaluronic acid (HA), a molecule your skin makes naturally and loses with age, which is why skin gradually looks drier and less elastic even before deep lines appear.
Profhilo: the gold-standard bio-remodeller
Profhilo contains one of the highest concentrations of HA on the market, injected at just five points on each side of the face. It spreads under the skin like honey, hydrating deeply while stimulating four types of collagen and elastin. The protocol is two treatments a month apart (£220 per treatment, £380 for the course at my clinic), with maintenance roughly every six months. It's my go-to for clients over 35 whose main complaints are laxity and dullness — the classic "my skincare isn't cutting it anymore" client.
Seventy Hyal: the accessible glow treatment
Seventy Hyal 2000 is a next-generation HA booster at a friendlier price point (£120 per treatment, £200 for two with me). It delivers excellent hydration and glow and is a brilliant first skin booster for clients in their late twenties and thirties — a demographic that now dominates aesthetics: UK reporting shows over half of injectable patients are now under 35, with 26–34 the largest single group.
Polynucleotides: hydration plus genuine regeneration
Polynucleotides (I use Plenhyage XL, £250) are different. Rather than simply hydrating, they signal your fibroblasts — the cells that manufacture collagen and elastin — to get back to work. They're the most exciting product I've added in years, particularly for under-eyes and sun-damaged skin. They deserve their own deep-dive, which you'll find in my full polynucleotides guide.
Which skin booster is right for you?
- First-timer, under 35, wants glow: Seventy Hyal.
- 35+, laxity and dullness, wants firmness: Profhilo.
- Dark circles, crepey under-eyes, sun damage, smoker's skin: polynucleotides.
- Wants volume or reshaping: none of the above — that's a dermal filler conversation, and increasingly a "both, layered" conversation, since combining modalities at different skin depths is exactly where good practice is heading in 2026.
What to expect: results, downtime and risks
Expect small injection bumps for 24–48 hours and possible pinpoint bruising. Results build gradually as collagen production ramps up — I tell clients to judge at week four, not day four. Skin boosters are low-risk in trained hands but they are still medical injectables: infection, bruising and swelling are possible, and product choice matters enormously. If you're having treatment in summer, read my summer aftercare guide — SPF genuinely protects your investment.
Book a skin consultation at my Loughborough clinic or my Leicester, Nottingham, Derby, Birmingham or Bristol clinics, and I'll assess honestly which — if any — of these is right for your skin.
