Is Regenerative Medicine Really the Future of Aesthetic Treatment?
Understanding Biostimulation and Separating the Science from the Hype
Aesthetic medicine is changing.
For many years, treatment was largely about correcting what we could see. A line appeared and we relaxed it. Volume was lost and we replaced it. A fold developed and we filled it.
Wrinkle-relaxing injections and dermal fillers remain extremely useful treatments, and there are still many situations where they are exactly the right choice.
But increasingly, aesthetic medicine is also asking a different question.
This is the thinking behind biostimulation, bio-remodelling and what is increasingly being called regenerative aesthetics.
The science is genuinely interesting. But, as so often happens in aesthetic medicine, the hype and marketing has sometimes travelled rather faster than the scientific underlying evidence.
Rather than simply correcting the visible signs of ageing, can we encourage the skin and underlying tissues to restore some of what they have lost?
What happens to our skin as we age?
Young skin is supported by an extracellular matrix containing collagen, elastin, hyaluronic acid and other components that give it strength, elasticity and hydration.
For more about the importance of collagen read Collagen, What It Is, Why You Lose It, and Why It Matters for Your Skin.
Fibroblasts are among the cells responsible for maintaining this structure. As we age, fibroblast activity declines and the balance between producing and breaking down these important components changes.
Gradually, skin becomes thinner, less elastic and less able to retain moisture. At the same time, changes are occurring in the deeper tissues of the face. See How Your Skin Ages.
Traditional aesthetic treatments largely address the consequences of these changes.
Biostimulatory treatments attempt something different; to influence the biological processes involved in maintaining and remodelling the tissue itself. This attractive proposition aims to regenerate your own, natural collagen and elastin; skin’s essential building blocks.
What does biostimulation actually mean?
The terminology can be confusing.
Biostimulation generally describes treatments that encourage the body's own cells to produce or remodel components such as collagen and elastin.
Instead of simply putting something into the skin to fill a space, the treatment produces a biological response.
This has an important consequences.
The results are not immediate.
They develop gradually over weeks or months as the tissue responds.
That gradual change is also one reason these treatments can produce particularly natural-looking results. Rather than suddenly looking different, patients may simply begin to look fresher or notice an improvement in the quality or firmness of their skin.
But different biostimulatory treatments work in different ways, and they should not all be regarded as interchangeable.
Which treatments stimulate the skin?
Several treatments now sit somewhere within the biostimulatory or regenerative-aesthetics family.
Sculptra
Sculptra is one of the most established collagen-stimulating treatments and has been used in medicine for more than two decades.
It contains Poly-L-lactic acid, or PLLA. Following injection, the particles initiate a controlled tissue response which stimulates fibroblasts and leads to the production of new collagen.
The process occurs gradually, which explains why Sculptra behaves very differently from a conventional dermal filler. The objective is not simply to put volume into the face. It is to encourage the tissues to rebuild some of their own structural support.
This makes Sculptra particularly interesting where facial ageing involves both deterioration in skin quality and more generalised loss of support or volume. Dr Forrester is particularly impressed with Sculptra as a collagen-stimulating treatment
Radiesse
Radiesse contains calcium hydroxylapatite microspheres and is another well-established injectable with significant evidence for biostimulatory activity.
Depending upon how it is used, it can provide structural support or be used in a more diluted form primarily to stimulate tissue remodelling.
Research has demonstrated effects on fibroblasts and components of the extracellular matrix, including new collagen and elastin formation.
This makes Radiesse particularly interesting when the objective is improvement in skin quality and firmness rather than simply filling a particular line or fold.
Polynucleotides
Polynucleotides are purified fragments of DNA which are injected into the skin and appear to influence several processes involved in tissue repair and skin quality.
They have attracted considerable attention in recent years and there is encouraging evidence for improvements in areas such as skin texture, hydration and elasticity.
However, they also illustrate why we should be careful with the word regenerative.
Polynucleotides have plausible biological mechanisms and promising clinical results, but their evidence base is considerably younger than that of treatments such as Sculptra. There is still much to learn about precisely where they are most useful and how best to use them.
Promising is not quite the same thing as proven.
Profhilo
Profhilo occupies a slightly different position.
It is made from hyaluronic acid, but it is not used as a conventional dermal filler. Rather than being placed to create shape or replace volume in a particular location, it spreads through the tissues and is intended to improve hydration and tissue quality.
It is often described as a bio-remodelling rather than a filling treatment.
For patients whose principal concern is skin quality rather than loss of facial structure, that distinction can be important.
So is this really regenerative medicine?
This is where terminology becomes important.
Regenerative medicine has become an extremely attractive phrase.
It suggests that instead of artificially altering the face, we can persuade the body to rejuvenate itself. Unsurprisingly, it is now being attached to an ever-increasing range of aesthetic treatments.
But a treatment should not become scientifically credible simply because somebody puts the word ‘regenerative’ in front of it.
Platelet-rich plasma, growth factors, exosomes, stem-cell preparations and numerous topical products have all been promoted using the language of regeneration. Some have plausible biological mechanisms. Some have interesting early evidence. Others have marketing claims that extend considerably beyond what has actually been demonstrated in patients.
That does not mean that these treatments will never prove valuable.
It means we should apply the same question to regenerative aesthetics that we should apply to every development in aesthetic medicine:

The future — and the latest trend
There is a slightly uncomfortable truth about innovation in aesthetic medicine.
A genuinely important new scientific direction can also become fashionable.
Biostimulation is a good example.
The idea that we can improve ageing tissues by stimulating biological processes rather than simply adding volume is an important development. There is increasingly good evidence behind several treatments that work in this way.
At the same time, regenerative medicine has become a marketing umbrella under which treatments with very different levels of scientific support are being gathered.
The two things can be true simultaneously.
Regenerative approaches may well represent an important part of the future of aesthetic medicine.
And some treatments currently being marketed as regenerative may turn out to have been little more than the latest trend.
Consider reading our article How Do I Know If a Cosmetic Treatment Works?
The right treatment still matters more than the category
Perhaps the most important point is that none of these treatments is automatically better simply because it is biostimulatory.
Sometimes the problem really is loss of structural volume, and a carefully placed dermal filler may be the appropriate treatment. See dermal fillers.
Sometimes muscle movement is producing unwanted lines, and a wrinkle-relaxing treatment may provide the best result. See anti-wrinkle injections.
For another patient, improving collagen production or skin quality may be much more important than adding volume at all.
And increasingly, good aesthetic treatment may involve thoughtful combinations of these approaches. See Skin Quality vs Volume Loss: What Treatment Do You Actually Need?
The question should therefore never simply be:
“Which biostimulator should I have?”
It should be:
“What is actually causing the changes that concern me, and which treatment, if any, is most appropriate?”
That is why your consultation matters more than your treatment.
The exciting part of modern aesthetic medicine is not that we have discovered a new label called ‘regenerative medicine’. It is that we are beginning to understand more about how ageing tissues behave and how different treatments can influence them.
The challenge is to separate that genuine scientific progress from the inevitable hype that accompanies it.
At The Cosmetic Doctors Company in Esher, Surrey, we believe biostimulation has an increasingly important role in aesthetic medicine. But our approach remains the same as with any other treatment: understand the problem first, consider the evidence, and recommend treatment only when there is a good reason to do it.
