In this episode of In Your Skin, we chat with cosmetic physician Dr Scott Allison about all things skin health and the science of ageing. Dr Allison breaks down the ageing process in a way that’s easy to understand, explaining how both internal (genetics, inflammation, stress) and external (sun exposure, skincare, lifestyle) factors play a role in how we age.

He shares his biggest insights on the importance of starting prevention early, why sunscreen is non-negotiable, and the shift away from “anti-ageing” to what he calls “positive ageing.” You’ll learn what treatments actually work (and which are worth skipping), how to spot early signs of collagen loss, and what it really means to look like the best version of your age.

Whether you're 25, 45, or 65, this episode is packed with practical tips, myth-busting truths, and a refreshing perspective on beauty that goes far deeper than skin.
