Rhus Javanica Extract

Rhus javanica extract comes from the stem of the Macassar kernel plant, native to Southeast Asia. The extract contains several bioactive compounds, including moronic acid and betulonic acid, which have been studied for their antioxidant and other biological properties.In skincare formulations, it functions primarily as an antioxidant, helping to neutralise free radicals that can contribute to skin ageing and oxidative stress. The ingredient has a history of traditional use in Asian medicine for various health applications.

As an antioxidant, Rhus javanica extract works by donating electrons to free radicals, neutralising them before they can damage skin cells and collagen. Free radicals are unstable molecules generated by UV exposure, pollution, and normal metabolism that can accelerate visible signs of ageing.The extract's bioactive compounds, particularly moronic acid, may also interact with enzymes involved in skin elasticity, though the topical efficacy of these mechanisms in skincare products requires further investigation.

Rhus javanica extract is typically incorporated into serums, gels, and moisturisers. As with all antioxidant ingredients, its benefits are maximised when applied to clean skin and followed by sun protection during the day, since antioxidants work best alongside UV defence to prevent free radical damage.

Rhus javanica extract is generally well-tolerated in skincare formulations. Those with known sensitivities to plants in the Anacardiaceae family should exercise caution.
