Inflammaging: How Chronic Low-Grade Inflammation Ages Your Skin and Body
Inflammaging is the slow rise in chronic inflammation with age. How it ages skin, what drives it (UV, senescent cells, belly fat, smoking), and the evidence-based ways to lower it.
Inflammaging is the term scientists use for the chronic, low-grade inflammation that builds up in the body as we age, even without an infection. The short answer: it is a well-established concept in aging research, and in skin it is linked to collagen breakdown, a weaker barrier and slower healing. The biggest drivers you can control are sun exposure, smoking, excess body fat, inactivity and poor sleep. No single supplement or cream "cures" inflammaging; the evidence favors daily sunscreen, a retinoid, exercise, not smoking and a Mediterranean-style diet.
The short answer
- The term was coined by Claudio Franceschi and colleagues in 2000 to describe the rising inflammatory state that accompanies aging (Franceschi et al., Ann N Y Acad Sci, 2000).
- It is now linked to many age-related diseases, from heart disease to type 2 diabetes (Franceschi et al., Nat Rev Endocrinol, 2018).
- Skin is both a target and a source: aged and sun-damaged skin releases inflammatory signals (Pilkington et al., J Invest Dermatol, 2021).
- Senescent ("zombie") cells are a major contributor because they secrete inflammatory molecules (Lee et al., Int J Mol Sci, 2021).
What drives inflammaging
| Driver | Why it matters |
|---|---|
| UV exposure | Triggers inflammation in skin |
| Senescent cells | Secrete inflammatory signals |
| Visceral fat | Releases inflammatory cytokines |
| Smoking | Oxidative stress, inflammation |
| Poor sleep, inactivity | Raise inflammatory markers |
As the immune system ages (immunosenescence), it becomes less precise and more prone to background inflammation. A 2023 review describes how this plays out in skin, where immune cells, fibroblasts and keratinocytes all change with age (Pająk et al., Int J Mol Sci, 2023).
How inflammaging shows up in skin
- Collagen loss: inflammatory signals raise enzymes (matrix metalloproteinases) that break down collagen and elastin.
- Barrier weakness: older skin repairs its barrier more slowly, so it gets dry and irritated more easily.
- Slower healing and more redness: chronic inflammation can worsen conditions like rosacea. See our rosacea complete guide.
- Photoaging: UV-driven inflammation is a main reason sun-exposed skin ages faster. Read photoaging vs chronological aging.
Evidence-based ways to lower it
- Sunscreen every day. In a randomized trial of 903 adults, daily sunscreen users showed no detectable increase in skin aging over 4.5 years, and 24% less skin aging overall than the discretionary-use group (Hughes et al., Ann Intern Med, 2013). Our sunscreen anti-aging guide covers how to use it.
- Use a retinoid to help rebuild collagen: retinol vs retinoid.
- Support your barrier with a ceramide moisturizer: ceramides for skin barrier repair.
- Move most days. Regular physical activity is associated with lower inflammatory markers.
- Don't smoke, and keep alcohol low.
- Eat mostly plants, fish, olive oil and nuts. Polyphenol-rich diets are being studied for slowing biological aging.
- Sleep 7–9 hours and manage chronic stress: see is cortisol face real?
What about anti-inflammatory supplements?
Fish oil, curcumin, resveratrol and others are widely sold for inflammation. Human data on skin aging are limited and mixed, and some interact with blood thinners. Talk to your doctor before starting them. Experimental approaches like senolytic drugs are covered in our senescent cells guide.
Frequently asked questions
Is inflammaging the same as inflammation from an injury?
No. Acute inflammation is a short, helpful response to injury or infection. Inflammaging is low-level, persistent and not tied to a single trigger.
Can you measure inflammaging?
Doctors can measure markers like C-reactive protein (CRP), but there is no single test for inflammaging. CRP can be raised for many reasons, so interpret it with your doctor.
Does sugar cause inflammaging?
Diets high in added sugar and refined carbohydrates are linked to metabolic problems and inflammation, and sugar also damages collagen through glycation.
Can skincare reduce inflammaging?
Sunscreen prevents UV-driven inflammation, and barrier-supporting moisturizers and retinoids improve skin health. Creams don't reverse whole-body inflammaging.
Bottom line
Inflammaging is real, measurable science, and it helps explain why skin ages faster with sun, smoking and an unhealthy lifestyle. The best tools are the boring, proven ones: daily sunscreen, a retinoid, exercise, good sleep and a healthy diet. Talk to your doctor before starting anti-inflammatory supplements.
