Skin Boosters vs Polynucleotides vs Profhilo: Which Treatment Is Best for Your Skin in 2026?

Have you noticed that your skin looks more tired, dehydrated or less firm than it used to?

Perhaps you’re noticing fine lines, uneven texture, a loss of glow or skin that no longer feels as smooth and plump as it once did.

You may have started researching aesthetic treatments and come across terms such as skin boosters, polynucleotides and Profhilo.

But what is the difference between them? Which treatment is best for mature skin? And do you really need injectable treatments to improve your skin quality?

At KWJ Skin Clinic in Horsham, I believe the most effective approach to aesthetic treatments starts with understanding your skin, your concerns and your goals.

There is no single treatment that is right for everyone. The best results come from choosing the right treatment for the right concern.

In this guide, I’ll explain the differences between skin boosters, polynucleotides and Profhilo, what each treatment aims to achieve, and how to decide which option may be suitable for you.

What Are Skin Boosters?

Skin boosters are injectable treatments designed to improve aspects of skin quality rather than significantly change the shape or structure of the face.

Many skin boosters contain hyaluronic acid, a substance naturally found in the body that helps support hydration. However, not all skin boosters are the same. Their ingredients, formulation and intended effects can vary considerably.

Depending on the product, skin boosters may be used to address concerns such as:

• Dehydrated-looking skin.

• Dullness and loss of radiance.

• Fine lines.

• Uneven skin texture.

• Reduced skin smoothness.

• Skin that feels less supple.

Unlike traditional dermal fillers, which can be used to restore or enhance facial volume, many skin boosters are intended primarily to improve skin quality.

Who might consider skin boosters?

Skin boosters may be worth discussing if your main concern is skin that looks dry, tired or lacking in luminosity.

They may also form part of a wider skin-rejuvenation plan.

However, the outcome depends on the specific product, your skin condition and your individual treatment plan. Skin boosters are not a replacement for treating every cause of skin ageing.

What Are Polynucleotides?

Polynucleotides are an increasingly popular treatment in aesthetic medicine, particularly among clients interested in improving skin quality through a more regenerative approach.

They are made up of chains of nucleotides, which are components of DNA. Some products used in aesthetics are derived from purified salmon or trout DNA.

Polynucleotides have attracted interest because of their potential role in supporting tissue repair and skin remodelling.

Research has investigated their effects on areas such as:

• Skin texture.

• Fine lines.

• Elasticity.

• Hydration.

• Overall skin quality.

• 
  

However, it is important to distinguish between promising research and proven clinical outcomes.

A 2025 systematic review found encouraging results from polynucleotide treatments, but the available studies were generally small and varied in their methods. More high-quality research is needed to establish the most effective treatment protocols and indications. 

What makes polynucleotides different?

The main difference is their intended biological action.

Rather than simply focusing on hydration, polynucleotide treatments are often discussed in relation to supporting skin repair and remodelling.

They may be considered for clients concerned about:

• Reduced skin elasticity.

• Fine lines.

• Poor skin texture.

• Signs of skin ageing.

• Certain areas where skin quality has deteriorated.

  
  

Polynucleotides are not a miracle treatment, and results are not guaranteed. A thorough assessment is essential before deciding whether they are appropriate.

What Is Profhilo?

Profhilo is an injectable treatment based on stabilised hyaluronic acid.

It is designed to improve skin hydration and support the appearance of skin quality and firmness.

Unlike conventional dermal fillers, Profhilo is not primarily intended to create facial volume or sculpt features.

It is often considered by clients who want their skin to look:

• More hydrated.

• Fresher.

• Smoother.

• More radiant.

• Less crepey.

• Improved in overall quality.

Profhilo is particularly relevant to conversations about skin remodelling, although individual results vary and it should not be presented as a surgical skin-tightening treatment.

Is Profhilo suitable for mature skin?

It may be suitable for some mature clients, depending on their skin condition and expectations.

However, mature skin can have several different concerns at the same time, including:

• Dehydration.

• Loss of elasticity.

• Pigmentation.

• Fine lines.

• Skin laxity.

• Loss of facial volume.

  
  

Profhilo may help address certain aspects of skin quality, but it cannot correct every sign of ageing.

Sometimes a different treatment—or a combination of carefully selected treatments—may be more appropriate.

The most important question is not simply:

“Which treatment is the most popular?”

It is:

“What does my skin actually need?”

A treatment that works beautifully for one person may not be the right choice for someone else.

Which Treatment Is Best for Mature Skin?

There is no universal answer.

Mature skin is not a single skin type. Two people of the same age can have completely different skin concerns.

For example, one client may have excellent skin elasticity but significant dehydration. Another may have good hydration but noticeable laxity, pigmentation or loss of facial volume.

This is why I believe personalised treatment planning is more important than following aesthetic trends.

During a consultation, I would consider:

1. Your skin quality

Is your main concern dehydration, texture, dullness or fine lines?

2. Your skin elasticity

Does your skin feel less firm or supple than before?

3. Your facial structure

Is the concern related to skin quality, or is there also a loss of facial volume?

4. Your previous treatments

Have you had dermal fillers, skin boosters, Profhilo or other aesthetic procedures?

5. Your expectations

Are you looking for a subtle improvement in skin quality, or are you hoping to address more significant facial ageing?

6. Your overall skin health

Your skincare routine, sun exposure, pigmentation, sensitivity and existing skin conditions may all influence your treatment plan.

The goal should be to select a treatment based on your individual needs—not simply choose the newest injectable on the market.

Can Skin Boosters, Polynucleotides and Profhilo Be Combined?

In some cases, different treatments may form part of a broader skin-rejuvenation plan.

However, combining treatments does not automatically produce better results.

The decision should depend on:

• Your skin condition.

• The products being used.

• The treatment areas.

• Your previous procedures.

• Appropriate treatment intervals.

• Your medical history.

• Your individual goals.

  
  

  There is no need to have multiple injectable treatments simply because they are trending.

  At KWJ Skin Clinic, the focus should always be on selecting treatments thoughtfully and avoiding unnecessary procedures.

  
  
  
  
  
  

  When Will You See Results?

  
  

  One of the most important things to understand about aesthetic treatments is that results can develop at different speeds.

  
  

  Some clients may notice an initial improvement in hydration or radiance, while other changes may take longer to become apparent.

  
  

  The timing depends on:

  
  

  • The treatment selected.

  • The product used.

  • Your skin condition.

  • The number of treatments recommended.

  • Your individual response.

  • Your skincare and lifestyle.

    
    

  With polynucleotides in particular, it is important to avoid promising dramatic or immediate results. Current research suggests potential benefits for skin quality, but treatment outcomes and protocols are not yet fully standardised. 

  
  

  A realistic treatment plan should explain what improvement may be possible, when it might become noticeable and what limitations to expect.

  
  
  
  
  
  

  Do You Need Injectable Treatments to Improve Your Skin?

  
  

  Not necessarily.

  
  

  Injectable treatments may be appropriate for some concerns, but they are only one part of skin health and rejuvenation.

  
  

  A good skincare routine, daily broad-spectrum SPF, appropriate active ingredients and consistent skin maintenance remain important.

  
  

  Depending on your concerns, other treatments may also be worth discussing, including:

  
  

  • Medical-grade skincare.

  • Microneedling.

  • HydraFacial.

  • Chemical peels.

  • Energy-based treatments.

  • Other suitable skin-rejuvenation procedures.

  The right approach depends on your skin—not on how many treatments you can fit into a treatment plan.

  
  
  
  
  
  

  Choosing the Right Skin Rejuvenation Treatment at KWJ Skin Clinic

  
  

  At KWJ Skin Clinic in Horsham, I believe aesthetic treatments should enhance your natural features while respecting the individuality of your skin.

  
  

  Whether you are considering skin boosters, polynucleotides, Profhilo or another treatment, the first step should always be a consultation.

  
  

  During your consultation, we can discuss:

  
  

  • Your main skin concerns.

  • Your desired results.

  • Your previous aesthetic treatments.

  • Which options may be suitable.

  • What results you can realistically expect.

  • Whether a treatment is appropriate for you.

  
  

  Sometimes the best treatment is not the one you initially had in mind.

  
  

  Sometimes improving your skin requires a combination of professional treatments and consistent home care.

  
  

  And sometimes, the best decision is to wait.

  
  

  Good aesthetics is not about doing more. It is about doing what is right for you.

  
  
  
  
  
  

  Frequently Asked Questions

  
  

  Is Profhilo better than polynucleotides?

  
  

  Neither treatment is universally better.

  Profhilo and polynucleotides have different formulations and intended uses. The most appropriate option depends on your skin concerns, medical history and treatment goals.

  
  
  
  

  Are skin boosters the same as Profhilo?

  
  

  No. Profhilo is a specific hyaluronic-acid-based injectable treatment. The term “skin booster” describes a broader category of treatments, and different products have different formulations and purposes.

  
  
  
  

  Are polynucleotides suitable for everyone?

  
  

  No. Suitability depends on your medical history, skin condition, the specific product and the treatment area. A consultation is essential before treatment.

  
  
  
  

  Can these treatments replace dermal fillers?

  
  

  Not always.

  Skin boosters, polynucleotides and Profhilo generally focus on skin quality. Dermal fillers may be used for specific concerns involving facial volume or structure.

  They have different purposes and should not automatically be considered alternatives.

  
  
  
  

  How many treatments will I need?

  
  

  The recommended number of treatments depends on the product, your skin condition and your goals. There is no single treatment schedule that is appropriate for everyone.

  
  
  
  

  Are these treatments permanent?

  
  

  No. Results are not permanent, and their duration varies between individuals and products. Your practitioner should explain expected longevity and any recommended maintenance.
