7 Eye-Opening Skin Facts (and Myths) Only a Cell Biologist Can Tell You

What if true skincare “anti-aging” happens deep below the surface? This week we’re exploring everything to do with what we’re dubbing “cell care” — the shift toward cellular longevity, skin health span and managing aging cells. Joined by Dr. Alessandra Zonari, chief scientific officer at OneSkin, we’re breaking down DNA repair, senescent “zombie" cells, red light therapy, exosomes vs. peptides and why skin collagen is like gluten in bread. This conversation is brought to you in part by OneSkin.

In this episode we cover:

• Genetics vs. habits: Why science shows that only 10 to 25 per cent of skin aging is genetic, leaving up to 90 per cent in your hands.
• Quiet saboteurs: The everyday habits—like cutting sleep repair windows short and switching products too fast—that sabotage long-term skin health span.
• DNA clocking: Surface skin scanners like VISIA don't tell the whole story; meet MolClock, with an algorithm that reads your DNA to reveal true cellular age.
• Is “collagen banking” legit? Why (contrary to TikTok belief) you cannot stock up on collagen inside your skin, and what to focus on if you really want to protect your collagen for longer.
• Is red light therapy worth it? The cell biologist weighs in.
• UV radiation and tanning: What sun damage looks like under a cell biologist’s microscope, and how UV rays accelerate dreaded “zombie” cells.
• Exosomes vs. peptides: Dr. Zonari breaks down the difference between targeted, single-message peptides and the complex delivery systems of topical exosomes.
• Sneak peek: Coming in September, hear the scoop on OneSkin’s next innovation, a new, richer version of its iconic Face Moisturizer, two years in development.
