Skin Longevity 101: Skin Health Starts in Your Cells
Urolithin A is an exciting new compound targeted to mitochondrial rejuvenation, with strong supportive science. In this article from my friends at Timeline, learn the science behind why I endorse an “inside-outside” strategy for reversing skin aging—combining their oral supplement Mitopure with topical benefits of their Mito-Biotic skincare line.

Skin health is not just about SPF. As the science of skin longevity evolves, it’s clear that the way we age on the outside is linked to what’s happening inside our cells.
I’ve always believed that longevity is a cellular story. Muscle, metabolism, immunity, and even skin, are all influenced by the vitality of our cells. And each of these systems plays a key role in how we age.
Why Skin Ages: More Than Wrinkles and Sunspots
Skin aging is a multifactorial process. While UV exposure, pollution, and lifestyle choices accelerate visible aging, the root causes start deep inside the cell.
- Mitochondrial dysfunction: Skin cells lose energy capacity as mitochondria become damaged and inefficient.
- Chronic oxidative stress: Damaged mitochondria produce excess reactive oxygen species (ROS), which degrade key structural components of the skin (e.g. collagen).
- Inflammaging: Low-grade chronic inflammation accelerates cellular breakdown, undermining barrier function and resilience.
Together, these processes create what dermatologists call intrinsic skin aging.
The New Lens: Skin Longevity
Recent research suggests that maintaining a strong, healthy skin barrier can help reduce the systemic inflammationassociated with aging.
Skin resilience is emerging as a vital indicator of biological age. In other words, healthy, energized skin doesn’t just look better, it performs better. It maintains proper hydration and prevents water loss, acts as a physical barrier against pathogens, and supports immune defense at our body’s front line.
Enter Mitopure®: A Longevity Breakthrough
This is what excites me about data-driven compounds like Urolithin A and Mitopure®.
Urolithin A is a compound that rejuvenates mitochondria through the activation of mitophagy, your cells’ natural process of clearing out damaged mitochondria and replacing them with healthier ones.
This bioactive nutrient is produced by the gut through the digestion of certain polyphenols. Unfortunately, the majority of the population doesn’t have the gut microbiome required to make Urolithin A naturally.
Mitopure represents a longevity breakthrough, enabling direct supplementation of Urolithin A in a clinically validated dose.
Topically Applied Mitopure for Skin Health
Originally investigated for its effects on muscle health, Mitopure has also shown empirical effects on skin health and appearance.
The skin is densely populated with mitochondria and highly dependent on their function. By restoring mitochondrial quality, Urolithin A addresses the root of skin aging.
In clinicals, topically applied Urolithin A has been shown to:
- Reduce the appearance of wrinkle depth and volume after only 2 weeks of use, with significant improvements after 8 weeks of use.
- Support collagen assembly.
- Helps skin resist extrinsic aging and protects against photodamage.
