Polynucleotides vs Skin Boosters: What's the Difference?

Two approaches to skin rejuvenation. Different formulations, different treatment goals. Which might suit your skin?

If you've been exploring injectable treatments for tired, dehydrated or ageing skin, you've probably come across two popular options: skin boosters and polynucleotides.

Both are used to improve aspects of skin quality, often without creating the noticeable facial volume associated with traditional dermal fillers.

However, they work differently, and the most appropriate option depends on your individual concerns.

There's also an important distinction: skin booster is a broad term used in aesthetic medicine. For this comparison, we're focusing primarily on hyaluronic acid skin boosters, which are commonly discussed alongside polynucleotide treatments.

Understanding the differences can help you make a more informed decision about your skin rejuvenation options.

What Is a Skin Booster?

Hyaluronic acid skin boosters are injectable treatments primarily used to improve skin hydration and appearance.

Hyaluronic acid is a substance naturally present in the body that can bind and retain water.

Unlike traditional dermal fillers designed to restore or enhance facial volume, many skin boosters are formulated and administered with the aim of improving skin quality.

Depending on the product and individual suitability, they may be considered for concerns such as:

• Dehydrated or dull-looking skin

• Reduced radiance

• Uneven skin texture

• Fine surface lines

• Skin that appears tired or less smooth

Some formulations may also be used with the aim of improving other aspects of skin quality.

The overall goal is often a smoother, fresher and more hydrated-looking complexion rather than a noticeable change in facial shape.

What Are Polynucleotides?

Polynucleotides are DNA-derived molecules used in certain injectable skin rejuvenation treatments.

Many formulations contain highly purified fragments derived from fish DNA, although the exact composition varies between products.

They are being investigated for their potential effects on skin repair, tissue regeneration and skin quality.

In aesthetic practice, polynucleotides may be considered for concerns involving:

• Fine lines and uneven texture

• Changes in skin elasticity

• Tired or ageing skin

• Certain concerns around the delicate eye area

• Specific scar or textural concerns, depending on the formulation

Unlike traditional volumising fillers, polynucleotide treatments are generally intended to support skin quality rather than create pronounced facial contours.

Research into their potential benefits is encouraging, but the evidence varies between indications and products, and more high-quality clinical studies are needed.

What's the Main Difference Between Skin Boosters and Polynucleotides?

The simplest distinction is their composition and the way they are intended to work.

Hyaluronic Acid Skin Boosters

Their primary emphasis is generally hydration and improving the appearance of the skin.

Polynucleotides

Their emphasis is often on supporting skin quality through biological processes associated with tissue repair and regeneration.

However, this isn't an absolute division.

Hyaluronic acid treatments may influence several aspects of skin quality beyond hydration, while polynucleotide treatments may also affect skin hydration and texture.

Neither category can automatically be considered better than the other.

The most important factors are the specific product, the available clinical evidence and your individual skin concerns.

Skin Boosters vs Polynucleotides: At a Glance

Although both treatments aim to improve skin quality, their ingredients and treatment approaches differ.

Skin Boosters — Hydration and Radiance

Main ingredient: Hyaluronic acid, sometimes combined with other ingredients.

Main focus: Improving skin hydration, smoothness and overall appearance.

Common concerns: Dehydrated skin, dullness, fine surface lines and reduced radiance.

Facial volume: Generally not intended to create significant facial volume.

Treatment course: Depends on the product. Some treatments involve multiple sessions spaced several weeks apart.

Polynucleotides — Skin Quality and Regenerative Support

Main ingredient: Purified DNA-derived molecules.

Main focus: Supporting skin quality and biological processes associated with tissue repair.

Common concerns: Changes in skin texture, fine lines, elasticity and certain specialist skin concerns.

Facial volume: Generally not intended to create significant facial volume.

Treatment course: Often involves a series of sessions, depending on the formulation and individual needs.

What Do They Have in Common?

Both treatments:

• Aim to improve aspects of skin quality.

• May offer subtle, gradual changes rather than dramatic facial reshaping.

• Can require more than one appointment.

• Involve injections and carry potential risks.

• Require an individual assessment to determine suitability.

The key difference: Hyaluronic acid skin boosters primarily focus on hydration and skin appearance, while polynucleotides are used for broader skin-quality concerns, with potential regenerative effects that are still being studied.

Neither is automatically better. The most appropriate choice depends on your skin concerns, the specific product and your individual treatment goals.

This comparison is a general educational guide, not a ranking of effectiveness. Individual products, indications and clinical evidence differ.

Which Treatment Is Better for Dehydrated Skin?

If your main concern is dehydration, dullness or reduced radiance, a hyaluronic acid skin booster may be worth considering.

These treatments are commonly selected because hyaluronic acid can attract and retain water.

However, skin that looks dehydrated doesn't always require injections.

Your skincare routine, skin barrier, underlying skin conditions and other contributing factors should also be considered.

A consultation can help determine whether an injectable treatment is appropriate or whether another approach would be more beneficial.

Which Treatment Is Better for Skin Elasticity and Fine Lines?

Changes in elasticity and skin texture are influenced by several factors, including ageing, sun exposure and changes in the skin's supporting structures.

Polynucleotides have attracted interest for their potential to improve aspects of skin quality, including texture and elasticity.

Some clinical studies have reported encouraging results, but larger, higher-quality trials are still needed to establish effectiveness for different indications.

Hyaluronic acid treatments may also improve the appearance of fine lines and skin quality.

There isn't enough reliable head-to-head evidence to conclude that one treatment category is consistently superior for every person experiencing reduced firmness or elasticity.

The choice should therefore depend on your assessment and the specific formulation being considered.

Where Does Profhilo® Fit In?

Profhilo® is an injectable treatment containing a high concentration of hyaluronic acid.

It is commonly used with the aim of improving skin hydration and overall skin quality rather than producing traditional filler-like facial contours.

Although it is often discussed alongside skin boosters, Profhilo® has its own formulation and recommended treatment protocol.

It may be considered for selected concerns involving skin quality, depending on individual suitability.

The distinction matters because not every hyaluronic acid injectable has the same properties, treatment technique or intended outcome.

What About Polynucleotides for the Eye Area?

The skin around the eyes is thinner and more delicate than in many other facial areas.

Concerns such as fine lines, reduced elasticity and changes in skin texture may become more noticeable over time.

Certain polynucleotide formulations are used specifically in the periocular area, with techniques adapted to the anatomy involved.

However, it's important to understand that not every under-eye concern is caused by poor skin quality.

Dark circles, puffiness and hollowness can have very different causes.

Polynucleotide treatments are not designed to correct every type of under-eye concern, and assessment is essential before recommending treatment.

Can Polynucleotides Help with Scarring?

Some polynucleotide products are being used or investigated for selected scar-related and textural concerns.

For example, specialist formulations such as VITARAN S® are marketed for particular tissue-quality applications.

However, scars differ significantly in their type, depth, maturity and underlying cause.

A treatment suitable for one kind of scar may not be appropriate for another.

The evidence supporting polynucleotides for scar-related concerns also varies, and treatment claims should be considered in relation to the specific product and indication.

Other approaches, including microneedling or referral for specialist dermatological assessment, may sometimes be more appropriate.

Do Skin Boosters or Polynucleotides Add Facial Volume?

Neither treatment category is generally chosen to create the structural volume associated with traditional dermal fillers.

However, injectable products differ in their composition, properties and administration techniques.

Some hyaluronic acid formulations can influence tissue fullness, even when improving skin quality is their principal purpose.

Polynucleotide treatments are generally intended to support skin quality rather than enhance facial contours.

If you are concerned about looking overfilled or changing your natural features, this is an important point to discuss during your consultation.

Understanding the exact product and its intended purpose is more useful than relying solely on the treatment category.

How Many Sessions Will I Need?

This is an important consideration when comparing skin rejuvenation treatments.

Some hyaluronic acid skin boosters, Profhilo® protocols and polynucleotide treatments involve an initial course of sessions, often spaced several weeks apart.

The number and timing depend on the individual product, treatment area, recommended protocol and your skin concerns.

For example, certain treatments may involve two sessions, while others may require three or more.

Results may develop progressively rather than being fully visible after the first appointment.

Before starting treatment, it's important to understand:

• The recommended number of sessions

• The interval between appointments

• When improvements may become visible

• The potential need for maintenance

• The total cost of the proposed course

An initial course and ongoing maintenance are not the same thing. Further treatment should be guided by reassessment rather than automatically repeated.

Can You Have Both Treatments?

In some circumstances, different skin-quality treatments may form part of a broader aesthetic plan.

However, combining products doesn't automatically produce better results.

There must be a clear reason for each treatment, with consideration given to product compatibility, timing, medical suitability and potential risks.

Sometimes one treatment may adequately address your concerns.

Sometimes a staged approach may be appropriate.

And sometimes an injectable treatment may not be necessary at all.

The aim should always be to choose an evidence-informed approach based on your individual needs, rather than combining treatments simply because they are available.

Are There Risks or Side Effects?

Both skin boosters and polynucleotide treatments involve injections and therefore carry potential risks.

Common temporary reactions may include:

• Redness or tenderness

• Swelling

• Bruising

• Small injection-site bumps

Other complications can occur, depending on the product and treatment technique. These may include infection, inflammatory reactions, nodules or allergic responses.

More serious vascular complications are possible with certain injectable techniques and products.

Your practitioner should explain the risks relevant to the specific treatment, assess contraindications and provide appropriate aftercare information.

For some fish-derived polynucleotide formulations, relevant allergy history is particularly important.

No injectable procedure should be described as completely risk-free.

How Do You Know Which Treatment Is Right for You?

You don't need to make this decision based on treatment trends, photographs or product names alone.

Perhaps your main concern is dehydration.

Perhaps you've noticed changes in texture or elasticity.

Or perhaps you simply feel that your skin no longer looks as refreshed as it used to.

Different concerns may require different approaches.

The most appropriate recommendation should consider your skin condition, medical history, treatment goals and the evidence supporting the products being discussed.

Sometimes a hyaluronic acid skin booster may be appropriate.

Sometimes a polynucleotide treatment may be worth considering.

And sometimes skincare, another treatment or no procedure at all may be the better recommendation.

The right treatment starts with understanding your skin — not simply choosing a product.
