Three Skin Boosters, Three Different Approaches
Profhilo, babyGLOW and Plinest are three of the most requested skin boosters in London clinics. They’re often grouped together because all three improve skin quality without adding volume. But the way each one works is quite different, which means the right choice depends on what your skin actually needs.
If you’re new to the category, our guide to what skin boosters are explains how they differ from fillers and the main product types.
Profhilo: Hybrid Hyaluronic Acid for Laxity and Bounce
Profhilo is made by the Italian company IBSA. It contains one of the highest concentrations of hyaluronic acid used in an injectable, combining high and low molecular weight hyaluronic acid in a stable hybrid form without traditional chemical cross-linking agents.
Once injected, Profhilo spreads under the skin from a small number of points on each side of the face. It hydrates deeply and stimulates collagen and elastin production, which helps improve skin firmness and elasticity over time.
Best for: – Early skin laxity and loss of bounce – Crepey texture on the face, neck and décolletage – Dehydrated skin in people from their thirties onward – Patients wanting a subtle “tightening” effect without filler
Typical protocol: Two sessions, about four weeks apart, then maintenance roughly every six months.
babyGLOW: Enriched Hyaluronic Acid for Radiance
babyGLOW is a skin booster treatment from Teoxane, the Swiss company behind the RHA filler range. At its core is Teoxane Redensity 1, combining non-cross-linked hyaluronic acid with amino acids, antioxidants, vitamins and minerals (Cosmetic Skin Clinic, 2025). Teoxane has reintroduced Redensity 1 under the babyGLOW name with a new injection protocol, using around 16 injections, eight on each side of the face, placed so the product spreads easily for a radiant finish (Get The Gloss, 2025).
The added nutrients are intended to support healthy skin function, while the hyaluronic acid hydrates and improves smoothness.
Best for: – Dull, tired or lacklustre skin – Dehydration and uneven texture – Fine lines and early signs of ageing – Patients wanting a “glass skin” glow before events
Typical protocol: A short course of sessions a few weeks apart, then maintenance every few months depending on skin.
Plinest: Polynucleotides for Repair and Regeneration
Plinest, made by the Italian company Mastelli, works differently from both. Instead of hyaluronic acid, it contains polynucleotides, highly purified DNA fragments usually derived from salmon. Polynucleotides support the skin’s natural repair processes, helping fibroblasts work more effectively and encouraging healthier, more resilient tissue.
Because Plinest focuses on regeneration rather than hydration alone, it’s often chosen for skin that is thin, damaged or slow to recover.
Best for: – Thin, fragile or crepey skin – Sun-damaged skin – Fine lines and textural damage – Mild acne scarring – Delicate areas such as around the eyes, with specific products from the same range
Typical protocol: A course of around three sessions, two to three weeks apart, then maintenance a few times a year.
Patients with fish allergies should mention this at consultation, since polynucleotides are often derived from salmon.
Profhilo vs babyGLOW vs Plinest at a Glance
| Profhilo | babyGLOW | Plinest | |
|---|---|---|---|
| Manufacturer | IBSA | Teoxane | Mastelli |
| Main ingredient | Hybrid high and low weight hyaluronic acid | Non-cross-linked hyaluronic acid with amino acids, antioxidants, vitamins and minerals | Polynucleotides (purified DNA fragments) |
| Main action | Deep hydration, collagen and elastin stimulation | Hydration, radiance and skin nourishment | Tissue repair and regeneration |
| Best for | Laxity, crepiness, loss of bounce | Dullness, dehydration, uneven texture | Thin, damaged or fragile skin, scarring |
| Injection points | Few set points per side | Around 8 per side | Many small injections across the area |
| Typical initial course | 2 sessions, 4 weeks apart | Short course, a few weeks apart | Around 3 sessions, 2 to 3 weeks apart |
| Typical maintenance | Around every 6 months | Every few months | A few times a year |
| Changes facial shape | No | No | No |
Protocols vary between clinics and patients, so treat these as a general guide.
Which Skin Booster Suits Your Main Concern?
Rather than choosing a brand first, start with what you want to improve.
| Your main concern | Often the best starting point |
|---|---|
| Skin feels less firm and bouncy | Profhilo |
| Crepey neck or décolletage | Profhilo |
| Dull, tired, lacklustre skin | babyGLOW |
| Want a radiant glow before an event | babyGLOW |
| Thin, fragile or sun-damaged skin | Plinest |
| Mild acne scarring or textural damage | Plinest |
| Dark circles or crepey under-eye skin | A polynucleotide product designed for the eye area |
In practice, many patients have more than one concern. A practitioner might recommend one product for the main issue, then add another later, for example Plinest to improve skin health followed by Profhilo for elasticity.
What Each Treatment Feels Like
All three involve small injections and are generally well tolerated.
- Profhilo: Only a few injection points per side, so the appointment is quick. Small raised bumps form at each point and usually settle within 24 hours as the product spreads.
- babyGLOW: Around 16 injections across the face, with small bumps that settle quickly.
- Plinest: Many small injections across the treated area, often described as more uncomfortable than the other two. Numbing cream helps.
Results Timeline Compared
| Stage | Profhilo | babyGLOW | Plinest |
|---|---|---|---|
| First 48 hours | Bumps settle as product spreads | Bumps settle, skin may look dewy | Small bumps and redness settle |
| 2 to 4 weeks | Improved hydration | Glow and hydration noticeable | Gradual improvement in skin quality |
| After full course | Firmer, bouncier skin | Radiant, smoother skin | Thicker, healthier-looking skin with better texture |
| Results last | Around 6 months | Around 4 to 6 months | Around 4 to 6 months, varying by skin |
Polynucleotides tend to show results more gradually, since they work by supporting the skin’s own repair rather than adding hydration directly.
Side Effects and Recovery
All three have minimal downtime. Common, temporary effects include:
- Small raised bumps at injection points
- Mild redness and swelling
- Tenderness and occasional small bruises
Plinest may cause slightly more visible redness and bumps because of the number of injections, usually settling within a day or two. Serious complications are uncommon when treatment is carried out by a trained practitioner using genuine products.
Treating the Neck, Décolletage and Hands
Skin boosters aren’t only for the face. Profhilo is commonly used on the neck and décolletage, where crepey skin and fine lines often appear early. Polynucleotides such as Plinest are also used on the neck and hands to improve thin, sun-damaged skin. babyGLOW is mainly used on the face for radiance, though protocols vary between clinics.
Treating these areas alongside the face keeps results looking consistent, since a smooth, glowing face can make an untreated neck look older by comparison.
Can You Combine These Skin Boosters?
Yes, though usually not on the same day in the same area. Because each works differently, they can complement each other over time. A common approach is to improve skin health with polynucleotides first, then add a hyaluronic acid booster for hydration and bounce.
They also combine well with other treatments. Fillers restore volume and anti-wrinkle injections soften expression lines, while skin boosters improve the skin surface. Our dermal filler treatments in South Kensington and anti-wrinkle treatment in South Kensington are often planned alongside a skin booster course.
Choosing by Age and Skin Stage
The right booster often shifts as skin changes.
| Life stage | Common starting point | Why |
|---|---|---|
| Late 20s to early 30s | babyGLOW | Focus on glow and hydration before major laxity appears |
| Mid 30s to 40s | Profhilo or babyGLOW | Early loss of bounce and dehydration |
| Mid 40s onward | Profhilo, often with Plinest | Laxity combined with thinner skin |
| Sun-damaged or scarred skin at any age | Plinest | Repair and regeneration come first |
These are general patterns. Skin type, sun exposure and lifestyle matter more than age alone.
Other Skin Boosters Worth Knowing
Profhilo, babyGLOW and Plinest are the most requested, but other skin boosters are also used in UK clinics. These include Restylane Skinboosters, Juvederm Volite and amino acid and hyaluronic acid combinations such as Sunekos. Each has its own protocol and strengths. A good practitioner will explain why a particular product suits you rather than recommending one by default.
How to Prepare for Your Appointment
- Avoid alcohol for 24 hours before treatment
- Avoid blood-thinning supplements such as fish oil for a few days, unless medically required
- Don’t book within two weeks of an important event
- Mention any allergies, including fish, and any recent treatments
- Arrive with clean skin if possible
Common Myths About These Skin Boosters
- “Profhilo is a filler.” It’s a skin booster that spreads through the skin rather than adding volume.
- “babyGLOW is completely new.” It uses Teoxane’s established Redensity 1 product with a new protocol.
- “Polynucleotides are made from human DNA.” Plinest uses purified DNA fragments usually derived from salmon.
- “You only need one session.” All three work best as a course.
How Brand and Technology Connect
Teoxane makes both babyGLOW and the RHA filler range, while IBSA and Mastelli focus on skin quality products. If you’re curious how Teoxane’s filler technology compares with other major brands, our guide to Juvederm vs Restylane vs Teoxane covers the filler side.
What Happens When Results Fade
All three skin boosters are gradually broken down or used by the body over time, so results slowly soften rather than disappearing suddenly. Your skin returns toward how it looked before treatment, not worse. Maintenance sessions keep improvements in place, and many patients find they need fewer top-ups once skin quality has been built up over a few courses.
Signs a Clinic Is Choosing Well for You
A thoughtful clinic will usually:
- Ask about your skincare routine, sun exposure and lifestyle before recommending a product
- Look at your skin in good light, sometimes with photographs
- Explain why one booster suits your concern better than the others
- Suggest a realistic course and maintenance plan rather than a single session
- Be honest if a skin booster isn’t the right answer, for example if volume loss is the main issue
In practice, the best results come when product choice follows a clear assessment of the skin, not the other way round.
Aftercare for All Three
Aftercare is simple and similar for each product:
- Avoid makeup for 12 to 24 hours
- Don’t touch, rub or massage the treated areas
- Skip strenuous exercise, saunas and alcohol for 24 hours
- Avoid facials, peels and laser treatments for around two weeks
- Wear SPF daily and keep skin moisturised
How to Choose a Clinic for Skin Boosters
Product choice matters, but practitioner judgement matters more. Look for a clinic that:
- Has a practitioner registered with the GMC, NMC or GDC
- Assesses your skin before recommending a product
- Explains why one product suits you better than another
- Uses genuine products and shows the box and batch details on request
- Gives written aftercare and plans maintenance with you
A clinic that recommends the same product for every patient is worth questioning, since these three boosters suit quite different skin types and concerns.
