You might have noticed that some people seem to age differently to others. This is one of the reasons two people of exactly the same chronological age can have very different biological skin ageing. Same age, similar lifestyle, but one person’s skin holds its quality and structure for significantly longer.
There are many reasons for this. Genetics, sun exposure, skincare habits. But one factor that is increasingly recognised as central to how we age is something most people have never heard of.
Inflammageing.
What inflammageing actually means
Inflammageing is a term used in longevity medicine to describe the chronic, low-grade inflammatory environment that becomes more common with ageing. Unlike the short-lived inflammation that follows an injury or infection, it is persistent and can contribute over time to changes in tissue function and repair.
Within the skin, inflammatory signalling, oxidative stress and cellular senescence can all influence collagen turnover, extracellular matrix quality and the skin’s ability to maintain itself.
As we get older, the immune system undergoes a gradual shift. It becomes less able to resolve inflammatory signals efficiently, leading to a state of sustained low-level inflammation throughout the body. Over time, this inflammatory environment is one of several factors that can contribute to more pronounced age-related changes in the skin.
Why this matters for how your skin ages
Collagen is the structural protein that gives skin its firmness, elasticity, and resilience. Fibroblasts, the cells responsible for producing collagen, are sensitive to the inflammatory environment they live in.
Fibroblasts do not work in isolation. Their behaviour is influenced by the surrounding cellular and inflammatory environment. With ageing, chronic inflammatory signalling, oxidative stress and cellular senescence can alter extracellular matrix remodelling and contribute to collagen degradation and reduced tissue resilience.
This is why inflammageing is not just a longevity medicine concept. It is directly relevant to everything we do in regenerative aesthetics.
Most patients come to us focused on what they can see. Lines, loss of firmness, changes in skin quality. But beneath those visible signs is often a biological environment that has been working against the skin for years. Addressing the surface without considering that environment is like redecorating a room without fixing the damp.
What drives inflammageing
The factors that drive inflammageing are not mysterious. Many of them are the same lifestyle factors that influence general health.
UV exposure is one of the most significant. Chronic sun damage creates persistent inflammatory signals in the skin that break down collagen and impair cellular repair over time. This is one of the reasons daily sun protection matters so much in a skin longevity strategy: it reduces an important source of cumulative UV-induced damage and inflammatory signalling within the skin.
Poor sleep quality drives systemic inflammation. During sleep, the body undertakes essential repair and regulatory processes. Chronic sleep deprivation disrupts these processes and sustains inflammatory signalling.
Chronic stress activates the body’s stress response pathways, which have downstream effects on inflammatory regulation. The relationship between psychological stress and skin ageing is not just anecdotal, it is biologically grounded.
Smoking introduces oxidative stress and inflammatory compounds directly into the tissue. Nutrition, metabolic health, alcohol consumption, and sedentary behaviour all contribute to the broader inflammatory burden that drives inflammageing over time.
None of this means that every patient with skin concerns is making poor lifestyle choices. Inflammageing is a natural part of ageing that happens to everyone to some degree. But the pace at which it progresses is genuinely influenced by these modifiable factors. Our guide to collagen banking through the decades explores how this philosophy applies at each stage of life.
Where biomaterial design becomes relevant
All injectable treatments produce a biological tissue response. What is increasingly interesting in regenerative aesthetics is how the design of a biomaterial influences the nature and duration of that response.
Particle size, shape and surface characteristics can influence how tissues and immune cells respond to an injectable material. This has led to growing interest in technologies designed to stimulate collagen while minimising unnecessary or prolonged inflammatory activity.
JULÄINE™ uses proprietary LaSynPro™ technology, with smooth, spherical PLLA microspheres designed to support collagen formation while limiting excessive immune activation. Preclinical and emerging clinical research cited by Nordberg Medical suggests that its microsphere design is associated with a relatively low-inflammatory tissue response.
Inflammageing and skin longevity
Skin longevity is a concept that is gaining significant traction within medicine and is central to how we approach treatment at Mediject.
Rather than focusing on looking younger, skin longevity focuses on maintaining healthy, functional skin for as long as possible. Preserving the biological environment in which skin cells can repair, regenerate, and maintain their quality over time.
Collagen banking and skin longevity are closely related ideas. Collagen banking asks how we support the skin’s structural quality over time. Skin longevity asks the wider question: how do we maintain healthy, resilient, functioning skin for as long as possible? Inflammageing helps explain why that strategy cannot begin and end with an injectable.
Inflammageing is an important part of the biology we need to understand when thinking about skin longevity. Addressing it means thinking about the skin from several directions: reducing cumulative UV damage, supporting barrier function, considering the wider factors associated with inflammatory and oxidative stress, and choosing aesthetic interventions thoughtfully.
No single treatment addresses inflammageing comprehensively. But understanding it changes how we think about everything we recommend.
Why I think about inflammageing in every consultation
Understanding inflammageing has not necessarily changed what I inject. It has changed the questions I ask.
When a patient points to a line, a change in skin quality or an area that suddenly seems to be ageing more quickly, I am interested in what they can see. But I am equally interested in why it might be changing.
Has something changed hormonally? Has there been significant weight loss? What has their lifetime sun exposure looked like? How are they sleeping? Are they under enormous stress? Do they smoke? What are they using on their skin? What treatments have they already had?
Because the thing a patient points to is not always the thing I think we should treat.
Sometimes what we are seeing is part of a much wider change in the skin, and simply treating the most visible sign can mean missing the bigger picture.
That is why conversations about inflammageing, collagen banking and skin longevity matter to me. They encourage us to move beyond asking, “What can I inject here?” and towards asking, “What is happening to this skin, and how can we support it well for the years ahead?”
And sometimes that leads to an injectable treatment. Sometimes it leads to better skincare, daily sun protection or a conversation about lifestyle. Sometimes it means doing less than the patient expected. And sometimes it means doing nothing at all, for now.
Because if I understand why something is changing, I can make a much more intelligent decision about whether it needs treating at all.
For me, that is where good regenerative aesthetics begins: not with a product, but with understanding the person and the biology in front of me.
Frequently asked questions
Is inflammageing the same as regular skin inflammation?
No. Inflammageing describes the chronic, low-grade inflammatory environment that becomes more common with ageing. It is not the same as the acute inflammation you experience after injury or infection. It has no obvious symptoms but can contribute over time to collagen breakdown and age-related changes in the skin.
Can you reverse inflammageing?
Inflammageing is part of the complex biology of ageing rather than a single condition that can simply be switched on or off. However, many of the factors associated with chronic inflammatory and oxidative stress are modifiable. Protecting the skin from UV exposure, not smoking, looking after sleep and general health, and maintaining good skin barrier function all contribute to a healthier environment for ageing skin.
Does everyone experience inflammageing?
Inflammageing describes an age-associated tendency towards chronic, low-grade inflammatory activity. The extent and biological consequences vary considerably between individuals.
How does this relate to regenerative aesthetics?
Understanding inflammageing encourages us to think more carefully about tissue biology, biomaterial design and the quality of the regenerative response we are trying to create. It is one reason there is increasing interest in treatments designed to stimulate collagen while minimising prolonged or unnecessary inflammatory activity. At Mediject, this informs how we think about treatments like JULÄINE™ and Ellansé within our regenerative aesthetics approach.
What can I do to slow inflammageing?
Daily broad-spectrum SPF is one of the most impactful things you can do. Beyond that, good sleep quality, stress management, not smoking, and a diet that supports anti-inflammatory metabolic health all contribute. At Mediject, we discuss these factors alongside any injectable treatment recommendation, because no syringe alone addresses the full picture.
Understanding inflammageing has not necessarily changed what I inject. It has changed the questions I ask.
Not just: “What can I treat?” But: “What is happening to this skin, and how can we support it well for the years ahead?”
That is where good regenerative aesthetics begins. Not with a product, but with understanding the person and the biology in front of me.
