Overview

Antioxidants are essential in protecting the skin from oxidative stress caused by everyday environmental aggressors — UV exposure, pollution, visible light, and screen exposure. While Vitamin C remains one of the most widely used antioxidants in skincare, concerns around stability and sensitivity have driven growing interest in newer alternatives.

In this video, Dermatologist Dr. Rajat Kandhari breaks down the science behind an emerging antioxidant Gallic Acid —derived from green tea, plants, and fruits — and why it's gaining traction in modern skincare. He unpacks what sets Gallic Acid apart: its stability, tolerability for sensitive skin, and antioxidant potency.

The conversation also delves into the skin's circadian rhythm — how it shifts between a daytime defence mode and a nighttime repair mode. Dr. Kandhari explains how antioxidant protection supports the skin's daytime defence against oxidative stress, and why this understanding is key to designing effective AM and PM skincare routines.
