Skin Ageing Unlocked

Daniel Yarosh, PhD – Molecular Biologist & DNA Repair Expert joins Fiona Clark and Dr Clare Kiely to explore the science behind DNA repair enzymes and their role in skin health.
In this episode, Dan explains how liposomal delivery systems allow DNA repair enzymes, derived from bacteria, plankton, and plants, to enter skin cells and accelerate the repair of UV-induced DNA damage.
The discussion covers:
How DNA damage drives skin ageing and disease
Why repair speed matters more than repair alone
The role of photolyase and light-activated repair
Clinical evidence in reducing immune suppression and actinic keratosis
Why consistent, daily use is key
A science-led conversation on how skincare is evolving beyond protection into active repair.

Kicking off Season 2 with a bang, Skin Ageing Unlocked returns with one of the most important conversations in beauty right now.
This month, co-hosts journalist Fiona Clarke and The Skin Diary co-founder Dr. Clare Kiely are joined by toxicologist Rani Ghosh, a UK and EU registered expert with 15+ years’ experience in chemical and product safety.
Together, they debunk common myths, such as ‘low-tox’, natural being ‘better’ and preservatives being ‘bad’. They look at which ingredient scanning apps aren’t worth using and the one that can be used instead. Plus, they discuss social media’s role in the fear of chemicals and how the algorithm rewards inflammatory language, retinol restrictions, endocrine disruptors, and SO much more.
If you’ve ever felt overwhelmed or anxious about skincare ingredients, this episode will leave you feeling informed, reassured, and back in control.
You can follow Rani on Instagram and TikTok where she shares straight-talking, science-backed insights into skincare and ingredient safety.
