Quercetin

What it is

Quercetin is a plant-derived flavonoid with antioxidant, anti-inflammatory and skin-soothing properties. Naturally found in foods like apples, onions and green tea, it helps protect the skin from oxidative stress caused by environmental factors such as pollution and UV radiation.

How it works in skincare

In skincare, quercetin has been gaining in popularity for the last year or so.

Anti-Ageing: Helps combat free radical damage, reducing signs of premature ageing such as fine lines and wrinkles. Anti-Inflammatory Effects: Soothes irritation and redness, making it beneficial for sensitive or reactive skin. Skin Barrier Support:  Strengthens the skin’s natural defences, helping to prevent moisture loss and irritation. Brightening: May assist in evening out skin tone by reducing oxidative stress that contributes to dullness and pigmentation.

It is often found in anti-ageing serums, moisturisers for sensitive skin and products designed to protect against environmental damage.
