Urolithin A for Fine Lines & Wrinkles
Fine lines and wrinkles are a normal, visible feature of skin aging, and the internet is full of ingredients that promise to erase them. Urolithin A is a cellular-energy compound with strong human data in other tissues and an emerging, mostly preclinical story in skin. This guide explains what is honestly known - and what is not - about urolithin A and skin appearance.
Why fine lines and wrinkles form
Wrinkles are a structural change in the skin, not a surface stain. Fine lines are shallow creases that often appear first around the eyes and mouth, where skin moves constantly and is thin. Deeper wrinkles develop as the underlying support of the skin weakens over years.
That support lives in the dermis, where fibroblast cells produce collagen for strength and elastin for recoil, organized within a matrix that holds water and keeps skin plump. As we age, fibroblasts make less collagen, matrix-degrading enzymes stay active, and elastin fibers fragment and lose spring. Sun exposure is the single largest accelerator, driving oxidative stress that damages both the matrix and the cells that maintain it. As the scaffold thins and disorganizes, the surface can no longer stay smoothly supported, and lines set in.
Underneath these visible changes sits a quieter one: the energy status of skin cells. Producing and repairing collagen is metabolically demanding, and fibroblasts fund that work with mitochondria, the cellular structures that generate usable energy. When mitochondrial quality declines with age, cells have less capacity to keep the matrix in good repair. That is the specific point where a mitochondrial compound like urolithin A enters the conversation about skin appearance.
What urolithin A is and how it works
Urolithin A is a gut postbiotic. You do not consume it directly; your microbiome makes it from ellagitannins in pomegranates, walnuts, and berries - and only some people host the bacteria that produce meaningful amounts. That variability is why standardized supplements are used in research.
Its central, best-studied action is supporting mitophagy: the cell's quality-control process for clearing out worn, underperforming mitochondria so healthier ones can replace them. Think of it as recycling the parts of the cell that make energy, keeping the working pool cleaner over time. For background, see our explainers on what mitophagy is and on mitochondrial health.
The proven human evidence sits outside skin
To talk about urolithin A honestly, we have to be clear about where the strong human data actually is - and it is not wrinkles.
HUMAN. The first-in-human trial (Andreux and colleagues, Nature Metabolism, 2019) showed urolithin A was safe and well tolerated up to 1,000 mg per day and produced a mitochondrial gene-expression signature consistent with improved mitochondrial biology. That is the anchor: the compound reaches human tissue and engages its target machinery.
HUMAN. In middle-aged adults, Singh and colleagues (Cell Reports Medicine, 2022) tested 500 mg and 1,000 mg daily over four months and reported support for muscle strength and exercise performance. Liu, D'Amico and colleagues (JAMA Network Open, 2022) reported support for muscle endurance in older adults over about four months. A 2025 Nature Aging randomized trial found that a roughly 28-day course supported immune-cell mitochondrial health in midlife adults, a marker relevant to age-related inflammation. Further randomized studies in resistance-trained men (Journal of the International Society of Sports Nutrition, 2024) and distance runners (2025) extend the evidence in active people.
These trials matter to a wrinkles page for one reason: they show, in living humans, that urolithin A supports mitochondrial quality in energy-hungry cells. Skin fibroblasts are energy-hungry cells too. That makes the skin question reasonable - but reasonable is not the same as demonstrated.
The wrinkle-specific evidence is early and preclinical
PRECLINICAL / EMERGING. There is no published human trial showing that urolithin A reduces fine lines or wrinkles. Skin appearance has not been a measured outcome in the human urolithin A studies completed to date. Skin-focused research on urolithin A remains early and preclinical, examining how supporting mitophagy and cellular energy might influence fibroblast behavior and the maintenance of the collagen-and-elastin matrix that keeps skin smooth. That is an active hypothesis, not a proven cosmetic result.
So the accurate structure/function framing is narrow and deliberate: urolithin A is studied for supporting the cellular energy systems that skin cells rely on. It is not shown to smooth wrinkles, plump lines, or change how your skin looks in the mirror. Any product that promises to erase wrinkles with urolithin A is describing hope, not human evidence - and we would rather you know the difference.
Sensible expectations and guidance
If reducing the appearance of fine lines is your goal, the highest-evidence steps are still daily broad-spectrum sun protection, not smoking, and topical approaches your dermatologist supports. Urolithin A is best thought of as a cellular-energy supplement with robust human mitochondrial and muscle data and an unproven - though mechanistically interesting - relationship to skin appearance. Studied doses run 500 to 1,000 mg per day, and the muscle benefits emerged over roughly four months, so think in terms of months of consistency, not overnight change.

Skin appearance is shaped by genetics, sun history, hormones, and medical conditions. Urolithin A is a structure/function supplement, not a wrinkle treatment, and it is not intended to diagnose, treat, or prevent anything. If you have a specific skin concern or are considering a cosmetic procedure, please see your doctor or a board-certified dermatologist rather than relying on a supplement.
Frequently asked questions
Will urolithin A get rid of my wrinkles?
No published human trial shows that urolithin A reduces fine lines or wrinkles. Skin appearance has not been a measured outcome in completed human studies. The skin research is early and preclinical, so we cannot claim a wrinkle benefit.
Then why is it discussed for skin at all?
Because skin fibroblasts depend on healthy mitochondria to maintain collagen and elastin, and human trials show urolithin A supports mitochondrial quality in other energy-hungry cells. That shared mechanism makes skin a reasonable research question - not a proven result.
Is it better than a topical retinoid or vitamin C?
They are not comparable. Retinoids and vitamin C have direct topical evidence for skin appearance; urolithin A is an oral cellular-energy supplement without human skin-appearance data. For fine lines specifically, follow your dermatologist's guidance.
What dose was used in human research?
Human trials used 500 mg to 1,000 mg per day, with 1,000 mg at the top of the studied range. SOMA HEALTH Urolithin A Gummies deliver 1,000 mg in a 4-gummy daily serving.
How long would I need to take it?
In the muscle trials, outcomes were assessed after about four months of daily use. Consistency over months is the realistic frame; nothing here works overnight.
Is urolithin A safe to take?
The first-in-human study found it safe and well tolerated up to 1,000 mg per day. Still, check with your healthcare provider before starting, particularly if you are pregnant, nursing, or on medication.
