polyphenols from green tea extract

Description

Polyphenols from green tea extract are potent antioxidant compounds derived from Camellia sinensis leaves. These bioactive molecules, primarily catechins, have gained significant attention in skincare formulations due to their multifaceted benefits for skin health. The most abundant and studied catechin in green tea is epigallocatechin gallate (EGCG), known for its powerful antioxidant and anti-inflammatory properties.

These polyphenols effectively neutralize free radicals, helping to prevent oxidative stress and premature skin aging. They also demonstrate photoprotective qualities, enhancing the skin's defense against UV-induced damage when used in conjunction with sunscreens. Green tea polyphenols have been shown to inhibit matrix metalloproteinases, enzymes responsible for breaking down collagen and elastin, thus supporting skin firmness and elasticity.

Furthermore, these compounds exhibit antimicrobial and sebum-regulating properties, making them beneficial for acne-prone skin. Research indicates potential in reducing redness and inflammation associated with various skin conditions. When incorporated into skincare products, green tea polyphenols are typically used at concentrations between 0.5% to 5%, depending on the formulation and intended benefits. Their stability can be enhanced through encapsulation techniques or by combining them with other antioxidants.
