Profhilo vs polynucleotides, why people compare them
Both treatments are often described as “skin boosters”, but they are not the same product and they do not work in the same way. In UK clinics, Profhilo is usually chosen for overall hydration and skin quality, while polynucleotides are often chosen when the skin looks fragile, crepey or inflamed, particularly around the under-eye area.
If your concerns are crepey under-eyes, uneven texture and a tired look, the “best” option depends on what is driving the problem, for example dehydration, thinning skin, inflammation, sun damage, lifestyle factors, or a combination.
What is Profhilo?
Profhilo is an injectable hyaluronic acid (HA) product designed for bio-remodelling. It is not a traditional dermal filler and it is not intended to create volume in the way a tear trough filler might.
Ingredients and mechanism
- Stabilised hyaluronic acid in a high concentration
- Designed to spread within the superficial tissues to support hydration and improve skin quality
- Commonly discussed in relation to supporting collagen and elastin in the months following treatment, although individual response varies
In patient terms, Profhilo tends to suit people who feel their skin looks dull, dehydrated, less firm, or generally “less fresh” across wider areas.
What are polynucleotides?
Polynucleotides are injectable products derived from purified DNA fragments. They are used with the aim of supporting the skin’s repair processes and improving the appearance of skin quality over time.
Ingredients and mechanism
- Polynucleotides (DNA fragments) in a gel or solution, depending on the brand
- Commonly used in regenerative-style protocols to support skin repair, barrier function and resilience
- Often selected when skin is thin, crepey, sensitised, or when there is visible “tiredness” around delicate areas
In patient terms, polynucleotides are often chosen when the goal is to improve how the skin behaves and looks gradually, especially in areas where volumising filler might not be suitable.
Key differences at a glance
| Feature | Profhilo | Polynucleotides |
|---|---|---|
| Main ingredient | Hyaluronic acid (HA) | DNA fragments (polynucleotides) |
| Main goal | Hydration and overall skin quality | Repair support and skin resilience |
| Typical areas | Face, neck, chest, hands | Under-eyes, face, neck, areas of thin or crepey skin |
| Best for | Dehydration, dullness, early laxity | Crepey texture, fragile skin, post-inflammatory look |
| “Glow” effect | Often earlier | Often later, more gradual |
| Under-eye suitability | Case dependent, careful technique needed | Commonly used for under-eye skin quality |
Best indications by concern
### Crepey under-eyes
Crepey under-eye skin can reflect thinning tissue, dehydration, inflammation, sun damage, and reduced elasticity. It can also be worsened by rubbing, allergies, eczema, or irritant skincare.
- Polynucleotides are commonly selected for under-eyes because they are used with the aim of improving skin quality and resilience rather than adding volume.
- Profhilo may help if dehydration and overall skin quality are the main issues, but the under-eye area is technically sensitive. Suitability depends on anatomy, skin thickness and injector experience.
Important note: If the main issue is a hollow tear trough, prominent fat pads, or laxity causing shadowing, skin boosters alone may be limited. Your clinician may discuss other options, for example conservative filler in suitable candidates, energy-based treatments, or skincare and lifestyle measures.
Texture and roughness
- If texture is mainly dehydration-related with general dullness, Profhilo is often a reasonable choice.
- If texture is linked to fragility, inflammation, or post-inflammatory change, polynucleotides are often considered.
Many people have both issues, so sequencing or combining can be discussed after assessment.
‘Tired skin’ and loss of freshness
“Tired skin” is usually a combination of dullness, dehydration, subtle laxity, stress, poor sleep, and sometimes under-eye changes.
- Profhilo may help with an earlier improvement in hydration and radiance.
- Polynucleotides may help with a slower, more gradual improvement in skin quality and resilience, especially if the skin looks thin or irritated.
Results timeline, what improves first and what takes longer
### Profhilo timeline
While experiences vary, many patients describe the following pattern:
– First 1 to 2 weeks: skin may look more hydrated, with a mild “glow” as hydration improves
– 4 to 8 weeks: skin texture and smoothness may improve gradually
– 2 to 3 months: any bio-remodelling effects are typically discussed in this window, but results are individual and not guaranteed
Polynucleotides timeline
Polynucleotides are usually described as a more gradual treatment:
– First 1 to 2 weeks: subtle improvements may be noticed, but some people feel changes are minimal early on
– 4 to 8 weeks: incremental improvements in texture and how the skin looks and feels can become more noticeable
– 2 to 4 months: improvements may continue as the skin’s repair processes are supported over time
How long do results last?
Duration depends on age, skin condition, lifestyle, sun exposure and whether you maintain results.
- Profhilo is often maintained every 4 to 6 months in some protocols.
- Polynucleotides are commonly maintained every 6 to 12 months, depending on the plan and the area treated.
These are general ranges. Your clinician should tailor recommendations to your skin, not a one-size protocol.
Typical UK treatment plans and maintenance
### Profhilo, common plan
– Often given as 2 sessions
– Common spacing is 4 weeks apart
– Maintenance may be discussed at 4 to 6 months depending on goals
Polynucleotides, common plan
- Often given as 2 to 3 sessions
- Common spacing is 2 to 4 weeks apart
- Maintenance plans vary, often every 6 to 12 months
Realistic expectations
These treatments can improve the look of skin quality, but they:
– Do not replace a surgical eyelid lift when there is significant excess skin
– Will not remove pigmentation or vascular dark circles on their own
– Are unlikely to correct strong structural hollowing without addressing volume or support where appropriate
A good consultation should separate concerns into skin quality, volume, pigment, and structure, then build a staged plan.
Downtime, side effects and aftercare
Both treatments are injectable and can cause short-lived skin reactions. Under-eye injections may bruise more easily because the skin is thin.
Common, expected side effects
- Small bumps at injection points for 24 to 72 hours
- Mild swelling, tenderness or redness
- Bruising, particularly around the eyes
Less common risks
- Infection
- Prolonged swelling
- Nodules or unevenness
- Inflammatory reactions
Serious complications are rare but possible with any injectable treatment. Seek urgent medical help if you experience severe pain, marked blanching, visual disturbance, or rapidly worsening swelling.
Practical aftercare (general guidance)
Follow your clinic’s specific instructions. Common advice includes:
– Avoid heavy exercise, alcohol and overheating (saunas, hot yoga) for 24 to 48 hours
– Avoid rubbing or massaging the area unless advised
– Keep skincare gentle for 24 hours, avoid strong actives if the skin feels irritated
– Plan treatment at least 2 weeks before major events if you bruise easily
When to choose Profhilo vs polynucleotides
### Profhilo may suit you if
– Your main issue is dehydration, dullness and early laxity
– You want a treatment that can improve overall skin quality across larger areas
– Under-eyes are not the primary focus, or you have been assessed as suitable for careful under-eye work
Polynucleotides may suit you if
- The under-eye area looks crepey, thin or fragile
- Your skin looks stressed, sensitised or inflamed
- You are looking for a gradual improvement in skin quality rather than an immediate glow
Can you combine Profhilo and polynucleotides safely?
In appropriate patients, clinicians may combine them, either in different areas (for example polynucleotides under the eyes and Profhilo in the lower face and neck) or in a staged plan.
Why combining can make sense
- Profhilo can support hydration and overall skin quality
- Polynucleotides may support repair and resilience, particularly in delicate areas
Typical ways clinicians may sequence them
- Start with polynucleotides for under-eyes, then add Profhilo for global hydration
- Use Profhilo first to improve general hydration, then polynucleotides to focus on thin, crepey areas
Spacing can vary. Your prescriber should consider skin sensitivity, bruising risk, upcoming events and how you responded to previous injectables.
Who should avoid treatment or seek extra caution
A face-to-face medical assessment is important, particularly for under-eye work.
Extra caution or delay may be advised if you:
– Are pregnant or breastfeeding
– Have an active skin infection, cold sore outbreak near the area, or significant dermatitis flare
– Have a known allergy to any ingredient in the chosen product
– Have uncontrolled autoimmune disease, are immunosuppressed, or have a history of significant inflammatory reactions to injectables
– Are taking blood thinners or have a bleeding disorder, as bruising risk can be higher
Always disclose your medical history, medications and supplements. If you have a history of recurrent swelling under the eyes, prior filler complications, or previous cosmetic procedures in the area, this should be discussed before treatment.
Choosing based on concern and budget
If you are deciding between Profhilo vs polynucleotides, a practical approach is:
– Choose Profhilo if your priority is overall hydration, glow and skin quality across broader areas
– Choose polynucleotides if your priority is crepey under-eyes and fragile texture
– Consider a combined plan if you have both under-eye crepiness and general dehydration, and you are suitable for treatment
Product choice, number of sessions and total cost vary between clinics and depend on the area treated. A transparent plan should explain what is likely to improve, how long it may take, and what the limits are.
Next steps
If you are considering Profhilo vs polynucleotides for crepey under-eyes, texture or tired-looking skin, an in-person consultation helps clarify what is driving your concerns and whether one treatment or a combination is appropriate.
