EP4 - Antioxidants: the science behind oxidative stress | NAOS

What really happens when free radicals attack your skin? ⚡ From UV rays to pollution, oxidative stress can damage proteins, lipids, and cells—speeding up skin ageing. Luckily, antioxidants are here to fight back!

In this episode of NAOS Life Science, Eloïse Collet explains what oxidative stress is, how free radicals are formed, and why antioxidants are essential to keep your skin healthy and resilient.

Discover how biomimetic antioxidants like vitamins and peptides replenish your skin’s natural defenses and protect it from daily aggressors.

👉 Did you know? A single free radical can trigger a chain reaction, damaging hundreds of molecules—until it’s neutralized by an antioxidant.

▶ What you will learn in this video:
What free radicals are and how they form in your body.
How oxidative stress damages proteins, lipids, and cells.
The crucial role of antioxidants in stopping free radical chain reactions.
Why NAOS uses biomimetic antioxidants for effective, skin-compatible protection.
