Skin boosters are one of the most requested treatments at our Central London aesthetics clinic, especially among women who feel their skin looks tired, dull or finely lined but do not want to look “done”. In London, Profhilo and 70 Hyal are two of the most common choices. Both are injectable hyaluronic acid treatments designed to deeply hydrate and improve skin quality, but they differ in concentration, feel in the skin, and ideal use cases.
At Alcove Aesthetics by Dr Goziem on Pall Mall, just moments from Mayfair and St James’s, we use both Profhilo and 70 Hyal within tailored treatment plans. Profhilo is ideal if you want a high-impact bioremodelling treatment to improve laxity and crepey texture, while 70 Hyal is better if you are seeking a more budget-friendly glow, gentle plumping and hydration boost, especially for fine lines. The best choice depends on your skin thickness, age, lifestyle, and how quickly you want to see results. This guide explains the differences clearly so you can walk into your consultation feeling informed and confident.
Introduction: Why London patients are choosing skin boosters over “filler”
Many of the women who visit Alcove Aesthetics in Central London are not looking for bigger lips or reshaped features. Instead, they want their own skin to look fresher, more rested and naturally luminous, without anyone guessing they have had treatment.
City living, long working hours, stress and pollution can all show up as fine lines, dullness, crepey skin and “tired” under eyes, even when you sleep and eat well. Traditional Dermal Fillers add volume, but they do not directly improve overall skin quality in the same way that true skin boosters do.
Profhilo and 70 Hyal are designed to hydrate from within, smooth the skin surface and subtly support collagen, so makeup sits better, pores look less obvious and the face looks quietly refreshed, not altered. Under the care of a doctor-led aesthetics clinic, they can be used alone or alongside other regenerative treatments for a comprehensive anti-ageing strategy.
What It Is & How It Works
What are skin boosters?
Skin boosters are injectable treatments based on hyaluronic acid (HA) – a molecule that naturally occurs in the skin and binds up to 1,000 times its weight in water. Unlike traditional fillers, which are usually thicker and designed to hold shape, skin boosters are made to be very soft and spreadable so they integrate seamlessly into the skin.
They are placed superficially in carefully mapped points to improve:
- Hydration and glow
- Fine lines and crepiness
- Skin texture and elasticity
They do not replace lost structural volume, but they make the skin envelope itself look healthier, firmer and more radiant.
Profhilo vs 70 Hyal: key differences
Both Profhilo and 70 Hyal are high-concentration HA treatments, but there are important distinctions.
Profhilo
- Contains 64 mg of HA in 2 ml, in a unique hybrid form (both high and low molecular weight)
- Classified as a bioremodeller rather than a classic skin booster
- Spreads widely through the tissue, stimulating fibroblasts to produce more collagen and elastin
- Typically performed as 2 sessions, 4 weeks apart, using a standardised 10-point injection pattern to treat the whole face
- Excellent for mild to moderate laxity and crepey skin, particularly in the lower face, neck and décolletage
70 Hyal
- Contains 70 mg of HA in 2 ml, usually in a monophasic gel form
- Acts primarily as a deep hydrator and skin quality booster rather than a true bioremodeller
- Often used with more flexible injection patterns, allowing targeting of specific concern areas such as fine lines around the mouth, cheeks or under-eye region (if suitable)
- Also usually delivered in a course of 2 sessions, 4 weeks apart
- Particularly helpful where hydration and fine-line plumping are the main goals, and budget is an important consideration
How skin boosters work in the skin
After injection, the HA gel attracts water into the tissue, increasing dermal hydration and giving the skin a smoother, more “dewy” appearance. Over the following weeks, the mechanical presence of HA and, in the case of Profhilo, its specific formulation, encourage the skin’s own cells to produce more collagen and elastin.
Under magnification, this translates to:
- Thicker, more resilient dermis
- Fewer micro-folds and less crepiness
- Improved light reflection, so the skin looks brighter
At Alcove Aesthetics, all skin booster treatments are carried out by Dr Goziem Onuchukwu, BDS, MSc (Aesthetic Medicine), an award-winning, GDC-registered dentist with over 7 years of experience and more than 1,000 patients treated. Each treatment plan begins with a full clinical consultation and often a wider skin strategy, which might also involve regenerative options such as Polynucleotides or collagen-stimulating injectables, depending on your needs.
Benefits & Results
Below is a side-by-side overview to help you compare Profhilo and 70 Hyal:
| Benefit / Feature | Profhilo | 70 Hyal |
|—————————–|———————————–|————————————–|
| Main action | Bioremodelling + hydration | Deep hydration + fine-line plumping |
| HA concentration | 64 mg / 2 ml | 70 mg / 2 ml |
| Best for | Crepey skin, early laxity, dullness | Dehydration, etched fine lines |
| Typical protocol | 2 sessions, 4 weeks apart | 2 sessions, 3-4 weeks apart |
| Areas commonly treated | Face, neck, décolletage, hands | Face, peri-oral lines, selected areas|
| Feel in skin | Very spreadable, no “lumpiness” | Soft gel, can be more targeted |
| Downtime | Pinprick bumps for up to 24 hours| Similar, often settles within 24 hrs |
| Longevity (average) | Around 6 months | Around 4-6 months |
Common benefits patients notice with either treatment:
- Fresher, more rested overall appearance
- Softer fine lines and less “crinkling” when smiling
- More even, luminous complexion
- Makeup sitting better, less patchiness
- Subtle firming of the lower face and neck (especially with Profhilo)
Results are gradual and build over several weeks, maintaining a very natural, “you on your best day” effect.

Treatment Journey
Step 1: In-depth consultation
Your journey begins with a thorough medical and aesthetic consultation with Dr Goziem. This includes:
- Detailed medical history and medication review
- Assessment of skin quality, thickness, elasticity and volume loss
- Discussion of your concerns (fine lines, dullness, under eyes, neck, hands) and lifestyle factors
- Clarifying whether Profhilo, 70 Hyal, or possibly other treatments such as PRP or collagen stimulators might be more appropriate
You will have time to ask questions and discuss realistic expectations, timelines and maintenance. A full treatment plan, including costs, is agreed before proceeding.
Step 2: Treatment day
On the day of your treatment:
- Your skin is cleansed thoroughly and photographs may be taken for your confidential medical record.
- Topical numbing cream can be applied, though most patients find skin boosters very tolerable.
- Dr Goziem uses fine needles and mapped injection points to place the Profhilo or 70 Hyal at the correct depth.
- You may see small, raised “bumps” at the injection sites which flatten as the product spreads over the next 12–24 hours.
A typical face treatment takes around 20–30 minutes once you are numbed, and you can usually return to work or normal activities immediately.
Step 3: Follow-up and maintenance
A second session is usually recommended 3–4 weeks after the first to consolidate results. At this visit, your response is reviewed and any minor adjustments are planned.
Maintenance is typically every 6 months for Profhilo and every 4–6 months for 70 Hyal, depending on age, lifestyle and baseline skin quality. At Alcove Aesthetics, follow-ups are offered for all treatments, so you are never left feeling unsure about what to do next.
Recovery & Aftercare
Skin booster treatments are minimally invasive with very little downtime. Common, short-lived effects include:
- Small raised bumps at injection points (usually settle within 24 hours)
- Mild redness or tenderness
- Occasional small bruises, especially around delicate eye or mouth areas
Aftercare guidance generally includes:
- Avoiding makeup on the treated area for 12 hours
- No vigorous exercise, saunas or steam rooms for 24 hours
- Avoiding facial massages or treatments directly over the area for about a week
Most patients notice an improvement in hydration within a few days, with the best results from Profhilo and 70 Hyal appearing gradually over 4–6 weeks as collagen stimulation and water-binding effects build.
Cost & Transparency
At Alcove Aesthetics, we offer clear, upfront pricing with a £50 booking fee redeemable against treatment and a 48-hour reschedule policy.
- Profhilo: £300 (1 session) | £550 (2 sessions)
- 70 Hyal: £250 (1 session) | £450 (2 sessions)
Many patients choose to combine skin boosters with other skin-focused treatments such as a Chemical Peel or microneedling for more comprehensive rejuvenation; this will be discussed and costed transparently at consultation.
Prices reflect doctor-led care in a Central London setting, using premium products, with aftercare and follow-up included.
FAQ: Profhilo vs 70 Hyal in London
Which is better: Profhilo or 70 Hyal?
Neither is objectively “better”; they are different tools. Profhilo is often preferred if you have early skin laxity, crepiness or sagging and want more structural skin improvement. 70 Hyal is ideal if your main issues are dehydration, fine lines and loss of glow, or if you are looking for a more cost-conscious option. A consultation will determine which (or which combination) is most appropriate.
Are Profhilo and 70 Hyal safe?
When administered by an experienced medical professional, both are generally very safe. They use biocompatible hyaluronic acid that is gradually broken down by the body. However, as with any injectable, there are potential risks such as bruising, infection or, rarely, vascular complications. At Alcove Aesthetics, all procedures are carried out by a medically qualified doctor with advanced training and full emergency protocols in place.
Do skin boosters hurt?
Most patients describe the treatment as mildly uncomfortable rather than painful. Topical anaesthetic cream is offered, and the injections are quick, using very fine needles. Any stinging sensation settles within minutes.
How long do results last?
On average, Profhilo results last around 6 months after the initial 2-session course. 70 Hyal results typically last around 4–6 months. Longevity depends on factors such as age, smoking, sun exposure, skincare and overall health. Regular maintenance is advised to keep your results consistent.
Who is not suitable for skin boosters?
Skin boosters are not suitable if you are pregnant or breastfeeding, have active skin infections in the treatment area, or have certain autoimmune conditions or allergies to product components. A full medical consultation with Dr Goziem is essential to confirm suitability and discuss alternative options if needed.
To explore whether Profhilo or 70 Hyal is right for your skin, and to design a natural-looking anti-ageing plan tailored to your lifestyle, you can book a dedicated skin consultation at our doctor-led facial aesthetics clinic in Central London.
