Epigallocatechin Gallatyl Glucoside

Epigallocatechin gallatyl glucoside (EGCG) is a polyphenolic compound found naturally in green tea. In skincare formulations, it functions as an antioxidant and skin conditioner, helping to neutralise free radicals that can damage skin cells and contribute to visible signs of ageing.This ingredient is relatively uncommon in skincare products, appearing in approximately 0.1% of formulations. It is often incorporated into microencapsulated systems or combined with other actives to enhance stability and efficacy.

Antioxidant. Hydrating. Reduces Irritation. Reduces Redness

As a polyphenol, EGCG works by donating electrons to neutralise free radicals—unstable molecules that can damage skin cells and trigger inflammation. This antioxidant action may help reduce the visible effects of environmental stressors such as UV exposure and pollution.The ingredient also appears to have mild anti-inflammatory properties, which may explain its association with reducing redness and soothing irritated skin. Its skin-conditioning role supports hydration and the overall resilience of the skin barrier.

EGCG is typically used as part of formulated products rather than as a standalone ingredient. It is often found in serums, moisturisers, or targeted treatment products. Use as directed by the product instructions. Because it is frequently microencapsulated or combined with other actives, consistency with the full product regime will support optimal results.

EGCG is generally considered safe and well-tolerated in cosmetic formulations. No significant safety concerns have been identified at typical use levels, though as with all skincare ingredients, patch testing is recommended for those with known sensitivities.
