Polynucleotides Versus Profhilo Compared

A client may arrive wanting brighter, firmer, more rested-looking skin, yet find that polynucleotides versus Profhilo is not a simple like-for-like choice. Both are injectable treatments designed to improve skin quality rather than dramatically alter facial shape, but they work in different ways and suit different concerns. The best option is the one that fits your skin’s current needs, your medical history and the result you would like to see over time.

At Evervine Medical Aesthetics, treatment planning begins with your skin rather than a trend. A careful consultation helps establish whether dehydration, crepiness, reduced elasticity, fine lines, redness, texture or more general signs of skin ageing are the main concern. From there, a qualified practitioner can recommend a considered route forward.

Polynucleotides versus Profhilo: the key difference

Profhilo is a high-concentration hyaluronic acid injectable treatment. Hyaluronic acid occurs naturally in the body and is known for its ability to bind water. Profhilo is often described as a bio-remodelling treatment because it is placed at specific points beneath the skin and then disperses through the surrounding tissue. Its purpose is not to create volume in the way a dermal filler can. Instead, it supports hydration, skin laxity and an overall fresher quality to the skin.

Polynucleotides are regenerative injectable treatments containing purified DNA fragments, commonly derived from salmon or trout. They are used to support the skin’s repair processes and create a more favourable environment for collagen and elastin production. Rather than primarily focusing on hydration, polynucleotides are often selected where skin appears fragile, dull, crepey, uneven or in need of more intensive restorative support.

In practical terms, Profhilo is frequently chosen for widespread hydration and a soft, luminous improvement in skin quality. Polynucleotides may be more appropriate when the priority is improving tissue quality, resilience and recovery in a particular area. There can be overlap, and neither treatment should be viewed as universally ‘better’.

What does Profhilo do for the skin?

Profhilo can be a considered option for clients who feel their face has begun to look tired, dehydrated or less supple, even when they do not want added volume or a noticeably ‘treated’ appearance. It is commonly used on the face, neck and décolletage, where skin can gradually lose bounce and smoothness.

A standard facial course often involves two sessions, usually spaced around four weeks apart. The treatment itself is relatively quick. Small raised areas can be visible at the injection points immediately afterwards, but these usually settle within a short period. Some clients experience mild tenderness, bruising or swelling, particularly if they are prone to bruising.

Results develop gradually. Skin may look more hydrated and feel smoother after the first treatment, while the more meaningful improvement is typically assessed after the full course. Profhilo is not designed to replace volume loss in the cheeks, define a jawline or erase deep folds. If those are your primary goals, another treatment approach may be more suitable.

What do polynucleotides do for the skin?

Polynucleotides are particularly valued for their regenerative focus. They can be used to support skin that has become thinner, more delicate or less even in texture. The under-eye area, cheeks, neck and areas affected by sun exposure are common treatment considerations, although the right placement and product choice should always be decided after an individual assessment.

Because the approach is centred on tissue support, results tend to be gradual and natural-looking. Clients may notice that their skin looks healthier, calmer and more refined over a course of treatment, rather than seeing an immediate transformation. For many people, this subtlety is exactly the appeal: the aim is to look well, not obviously injected.

A course may involve two to three sessions, depending on the product used, the area being treated and the condition of the skin. Your practitioner may then recommend maintenance at intervals tailored to your response and long-term goals. As with any injectable procedure, temporary redness, swelling, sensitivity and bruising can occur.

It is also essential to disclose allergies, medical conditions, medication, previous aesthetic treatments and pregnancy or breastfeeding status during consultation. As many polynucleotide products are fish-derived, they may not be suitable for everyone, particularly those with a relevant fish allergy. A Nurse Prescriber-led assessment provides an important layer of safety here.

Which treatment is best for your concern?

If your principal concern is dehydration, mild laxity and skin that no longer has the glow it once did, Profhilo may be an excellent place to start. It suits clients looking for a refined, all-over improvement with minimal disruption to their routine. It can be especially appealing before a significant event, provided there is sufficient time for the treatment course and any temporary swelling to settle.

If your skin appears more compromised - perhaps crepey around the eyes, uneven in texture, thin, lacklustre or slow to recover - polynucleotides may offer a more targeted regenerative strategy. They are often considered by clients who want to prioritise skin health and quality over a quick cosmetic fix.

Age alone is not the deciding factor. A person in their thirties with sun damage, poor skin quality or a demanding lifestyle may benefit from a different plan than someone in their fifties with well-hydrated skin but localised crepiness. Your homecare routine, sun exposure, smoking status, hormones, stress and previous treatments all influence the recommendation.

Can you have polynucleotides and Profhilo together?

In some cases, yes. Polynucleotides and Profhilo can complement one another when used within a well-planned treatment journey. For example, one treatment may be selected to focus on delicate, compromised tissue while the other supports overall facial hydration and elasticity. The timing matters, as does avoiding unnecessary treatment simply because two options are available.

A personalised plan may also include medical-grade skincare, SPF and, where appropriate, other rejuvenation treatments. Injectable treatments can support skin quality, but they cannot compensate for daily UV exposure, an unsuitable skincare routine or unrealistic expectations. Consistent sun protection and active skincare selected for your skin type can make a significant difference to how long your results look their best.

The safest approach is to introduce treatments thoughtfully and review how your skin responds. This is preferable to layering several procedures at once and being unable to tell what is helping.

What to expect from your appointment

Before either treatment, you should receive a full consultation covering your goals, medical history, allergies, current medication and suitability. Your practitioner should explain the product being used, where it will be placed, the likely treatment course, possible side effects, aftercare and realistic outcomes. You should never feel rushed into proceeding.

On the day, the skin is cleansed and injection points are carefully planned. Discomfort is usually manageable, though sensitivity differs from person to person. Avoiding alcohol, strenuous exercise, intense heat and unnecessary touching of the area immediately after treatment is commonly advised. Your own aftercare guidance should take priority, as recommendations can vary according to the treatment and area.

Choose a medically qualified practitioner who understands facial anatomy, can manage complications appropriately and is willing to say when a treatment is not right for you. A premium aesthetic result is not about having more injected. It is about making a clinical decision that respects your features, skin and confidence.

If you are deciding between these treatments, bring photographs of your skin from a few years ago, describe what has changed and be honest about what you hope to achieve. The right plan should leave you feeling informed, cared for and quietly confident in the skin you are in.
