What a skin booster is (and isn’t)
| Skin booster | Dermal filler | Anti-wrinkle injection | |
|---|---|---|---|
| Goal | Skin quality: hydration, elasticity, glow | Volume and contour | Soften expression lines |
| What it contains | Bio-remodelling HA, polynucleotides, amino acids or meso cocktails | Cross-linked hyaluronic acid gel | Botulinum toxin |
| Placement | Spread through the skin (points or mesh) | Deep, in specific pockets | Into targeted muscles |
| Result | Subtle, all-over skin improvement | Visible structural change | Smoother forehead/eyes |
| Course | 2–3 sessions, then 6-monthly | 1 session, top-ups 9–18 months | Every 3–4 months |
They work well together
A common plan: filler for structure, anti-wrinkle injections for dynamic lines, and a skin booster to make the skin itself look healthier over the top. Each does a job the others can’t.
The skin booster families, compared
| Product family | Main strength | Typical course | Best for |
|---|---|---|---|
| Profhilo / bio-remodelling HA | Deep hydration + mild collagen/elastin boost; “glow” | 2 sessions, 4 weeks apart | Widespread mild laxity, dull dehydrated skin |
| Seventy Hyal / similar HA boosters | Hydration and plumpness | 2–3 sessions, 2–4 weeks apart | Dry, tired skin wanting a fresher look |
| Polynucleotides | Skin repair, anti-inflammatory, elasticity | 2–3 sessions, 2–4 weeks apart | Thin, crepey, sun-stressed skin; under-eye quality |
| Sunekos (amino acids + HA) | Stimulates the skin’s own HA and collagen matrix | 4 sessions, ~1–2 weeks apart | Fine lines, under-eye, overall quality |
| Mesotherapy cocktails | Customisable vitamins/antioxidants/HA | 4–6 sessions, then maintenance | Radiance, mild pigmentation, general “glow-up” |
Formulations and brand names change; your practitioner recommends based on your skin and goal, not a single favourite.
Areas treated
- Face — cheeks, overall dullness, early laxity
- Under-eye — crepey, thin, tired-looking skin (polynucleotides especially)
- Neck and décolletage — “tech neck” lines, crepe texture, sun damage
- Hands — thinning, crepey skin
- Around the mouth — fine lines and dryness
The treatment course
- Consultation
Skin assessment, goal-setting and product selection. Photos for comparison.
- Session 1
Numbing cream, then the booster is placed with a fine needle or cannula — a series of points or a light mesh. 15–30 minutes.
- Sessions 2–4
At the interval for the chosen product (typically 2–4 weeks).
- Review & maintenance
Assessed at 4–12 weeks against baseline photos; then a maintenance session about every 6 months.
Results and timeline
Illustrative time to a clearly visible change after starting a course. Hydration-led boosters show earlier; repair-led boosters build slower but deeper.
Early on, skin looks more hydrated and plumper — partly the product. The lasting improvement in elasticity, texture and tone develops over the following weeks as the skin’s own collagen and elastin respond. Results are maintained, not permanent.
Which skin booster is right for you?
Book a complimentary skin assessment. We’ll match the right booster to your skin and design a course around your goal.
Downtime and safety
- Small raised bumps at injection points for a few hours to a day; possible minor bruising (more likely under the eyes and on the neck).
- Back to normal the same day; make-up after 12–24 hours.
- Avoid strenuous exercise, saunas, alcohol and active skincare for 24–48 hours.
Not suitable / discuss first
Pregnancy or breastfeeding, active skin infection or cold sore in the area, autoimmune disease, tendency to keloid scarring, and (for fish-derived polynucleotides) a true fish allergy. Space treatment a couple of weeks from dental work and other injectables.

Frequently asked questions
How much do skin boosters cost in Knightsbridge?
A single session is about £200–£400 in London. A Profhilo course of two is roughly £500–£800, a polynucleotide course of three £600–£1,000, and a Sunekos course of four £700–£1,200. Maintenance sessions every six months are priced like a single session.
What’s the difference between a skin booster and filler?
A skin booster improves the quality of the skin — hydration, elasticity, glow — by spreading hydrating or repair ingredients through it. Filler adds structural volume in specific pockets to change contour. They do different jobs and are often combined.
Which skin booster is best?
There isn’t one “best”. Profhilo and similar HA boosters lead on all-over hydration and glow; polynucleotides lead on repair and thin, crepey or under-eye skin; Sunekos and mesotherapy target fine lines and radiance. The right choice depends on your skin and goal.
How many sessions will I need?
Most courses are two to four sessions two to four weeks apart, depending on the product. Results are then maintained with a session about every six months.
When will I see results?
Hydration-led boosters show a fresher look within two to three weeks; repair-led boosters like polynucleotides build more slowly over six to ten weeks but deliver a deeper change in skin quality.
Is there any downtime?
Minimal — small bumps at the injection points for a few hours to a day, and possible minor bruising, especially under the eyes and on the neck. You can return to normal the same day and wear make-up after 12–24 hours.
Can skin boosters help under-eye dark circles?
They help when the shadowing is caused by thin, poor-quality, crepey skin — polynucleotides in particular improve skin thickness and texture there. They don’t correct pigmentation or deep tear-trough volume loss, which need other treatments.
Can I combine a skin booster with filler or anti-wrinkle injections?
Yes — it’s a very common plan. Filler for structure, anti-wrinkle injections for expression lines, and a skin booster to improve the skin itself. Treatments are usually spaced a couple of weeks apart.
Are skin boosters safe?
Yes, when a CE/UKCA-marked product is injected by a trained medical practitioner after a proper assessment. They’re avoided in pregnancy and breastfeeding, over active skin infections, and (for fish-derived polynucleotides) with a true fish allergy.
Do the results last?
No treatment in this category is permanent. A completed course typically lasts around six months before a maintenance session, and diligent sun protection meaningfully extends how long the improvement holds.
