Skin regeneration, collagen support and long-term skin health are becoming an increasingly important part of modern aesthetic medicine. But what does it actually mean to support the skin's natural regenerative processes?
As our skin ages, changes occur beneath the surface. Collagen production gradually declines, skin elasticity can reduce, and the skin may become thinner, drier or less resilient.
While traditional aesthetic treatments have often focused on addressing visible signs of ageing, regenerative aesthetics takes a broader approach, considering the biological processes that influence skin quality over time.
One area attracting growing interest is polynucleotides, a group of molecules being studied for their potential role in tissue repair, skin regeneration and aesthetic medicine.
But what exactly are polynucleotides, how do they work, and what does the science tell us?
What Are Polynucleotides?
Polynucleotides are long chains of nucleotides, the building blocks that make up DNA and RNA.
DNA is naturally present in our cells and plays an essential role in how the body functions, repairs and maintains itself.
In aesthetic medicine, certain purified polynucleotide formulations are being investigated and used internationally for their potential to support processes involved in tissue repair and skin quality.
These formulations are commonly derived from purified fish DNA, although their composition, manufacturing processes and intended uses can vary between products.
Polynucleotides are often discussed in the context of bioregeneration, an approach that focuses on supporting the biological environment of the skin rather than simply changing its external appearance.
Why Does Skin Quality Change as We Age?
To understand why regenerative approaches are receiving attention, it helps to understand what happens within our skin over time.
Our skin is a complex organ made up of several layers, each with an important role in maintaining its structure, function and appearance.
Within the dermis, fibroblasts are specialised cells involved in producing collagen, elastin and components of the extracellular matrix.
These structures help give our skin its firmness, flexibility and resilience.
As we age, several changes can occur:
● Collagen production declines: Contributing to changes in skin firmness and structure.
● Elastin fibres change: Affecting the skin's ability to stretch and return to its original shape.
● Skin hydration decreases: Making fine lines and uneven texture more noticeable.
● Cellular repair processes change: Influencing how the skin responds to environmental stress and injury.
● The skin barrier may become less resilient: Increasing susceptibility to dryness and irritation.
Sun exposure, hormonal changes, lifestyle and genetics can also influence these processes.
As collagen production gradually declines, changes in skin firmness, elasticity and texture can become more noticeable. Understanding the role of collagen is an important part of exploring different collagen stimulation treatments and approaches to long-term skin health.
This is why two people of the same age can have very different skin concerns and treatment needs.
How Do Polynucleotides Work in the Skin?
Polynucleotides have attracted scientific interest because of their potential interactions with processes involved in tissue repair and regeneration.
Laboratory and early clinical research has explored several possible mechanisms.
1. Supporting Fibroblast Activity
Fibroblasts play an important role in maintaining the skin's structural framework.
Research into certain polynucleotide formulations suggests they may influence fibroblast behaviour and cellular processes associated with tissue repair.
Because fibroblasts are involved in producing collagen and other extracellular matrix components, this has become an area of interest in regenerative aesthetic medicine.
However, laboratory findings do not necessarily translate directly into visible clinical improvements, and more high-quality human research is needed.
2. Supporting the Skin's Repair Environment
Healthy skin relies on a coordinated response between cells, structural proteins and signalling molecules.
Polynucleotides have been investigated for their potential role in creating an environment that supports tissue repair.
This is particularly relevant to research into wound healing and tissue regeneration, although the evidence for different aesthetic applications continues to develop.
3. Hydration and Skin Quality
Hydration is essential for maintaining comfortable, resilient skin.
Certain polynucleotide formulations have been studied for their physical properties and possible effects on skin hydration and elasticity.
These effects depend on the specific formulation and cannot be assumed to apply equally to all polynucleotide products.
Polynucleotides vs Hyaluronic Acid: What's the Difference?
Hyaluronic acid is a naturally occurring molecule found throughout the body, including in the skin.
It is known for its ability to bind water and plays an important role in tissue hydration.
Polynucleotides, on the other hand, are chains of nucleotides that are being investigated for their interactions with cellular repair processes.
Although both are discussed in aesthetic medicine, they are not interchangeable.
Hyaluronic acid is commonly associated with hydration and, depending on its formulation, volume restoration. Polynucleotides are being studied for potential effects on tissue quality and repair-related biological pathways.
Importantly, the evidence, approved uses, risks and expected outcomes differ between individual products.
What Skin Concerns Are Polynucleotides Being Studied For?
Research into polynucleotides in aesthetic medicine has explored several areas of skin quality, including:
● Fine lines and changes in skin texture
● Skin hydration and elasticity
● Changes associated with photoageing
● The appearance of delicate skin around the eyes
● Tissue recovery and repair
While some studies have reported encouraging findings, much of the aesthetic evidence remains limited by small sample sizes, different formulations and relatively short follow-up periods.
Polynucleotides should therefore not be viewed as a universal solution for skin ageing, and results reported for one formulation or treatment protocol cannot automatically be applied to another.
What Is the Difference Between Skin Regeneration and Skin Rejuvenation?
You may have noticed the terms skin regeneration and skin rejuvenation being used more frequently in aesthetic medicine.
Although they are sometimes used interchangeably, they describe slightly different concepts.
Skin rejuvenation generally refers to approaches intended to improve visible characteristics of the skin, such as texture, pigmentation, fine lines and overall appearance.
Skin regeneration refers more specifically to biological processes involved in tissue maintenance, repair and renewal.
In aesthetic medicine, regenerative approaches aim to understand and potentially influence these processes. However, the term regenerative does not, by itself, establish that a particular treatment has been clinically proven to regenerate skin.
Different technologies work through different mechanisms. For example, DENSITY RF® uses radiofrequency energy to deliver controlled heating within the skin, with the aim of supporting collagen remodelling and improving skin firmness.
At Ocean Cosmetics, our approach to skin health considers both the visible concerns patients present with and the underlying factors that may be contributing to changes in their skin.
Why a Personalised Approach to Skin Health Matters
There is no single treatment or ingredient that addresses every aspect of skin ageing.
For some patients, the priority may be pigmentation or redness. For others, it may be skin laxity, changes in texture, dehydration or maintaining skin quality over time.
Understanding the cause of these changes is an important part of developing an appropriate treatment plan.
Understanding how different treatments work can also help patients make informed decisions. Our guide to DENSITY RF vs HIFU explores the differences between these technologies and their approaches to skin tightening.
At Ocean Cosmetics, our doctor-led approach begins with a comprehensive assessment of your skin, medical history, concerns and goals.
Depending on your individual needs, your clinician may discuss skincare, sun protection, laser and energy-based treatments, or other clinically appropriate options.
We believe that long-term skin health is best supported through thoughtful treatment planning, realistic expectations and an understanding of the science behind aesthetic medicine.
The Future of Regenerative Aesthetics
Regenerative aesthetics is an evolving area of medicine, with ongoing research exploring how cellular processes, tissue repair and skin biology may inform future treatments.
Polynucleotides are one example of this growing scientific interest.
While early research is promising in some applications, larger, well-designed clinical studies are needed to better understand their effectiveness, safety, ideal treatment protocols and long-term outcomes.
For patients, the most important consideration is not simply whether a treatment is new or popular, but whether it is supported by appropriate evidence and suitable for their individual needs.
