EUK 134 is primarily used in skincare and cosmetic formulations for its antioxidant properties. It helps protect the skin from oxidative stress caused by free radicals and environmental aggressors like UV radiation and pollution. By mimicking the activity of natural antioxidant enzymes such as superoxide dismutase and catalase, it supports the skin’s defense system, reducing signs of aging including fine lines, wrinkles, and loss of elasticity. It is commonly found in anti-aging creams, serums, and lotions, where it enhances the stability and efficacy of other active ingredients. Due to its ability to regenerate damaged cellular components, it is also studied for use in products targeting photoaged or sensitive skin.
