Artemisia Princeps Leaf … Extract

Artemisia princeps (also known as Japanese mugwort) is a perennial plant native to East Asia. The leaf, stem, and twig extract contains bioactive compounds, primarily polyphenols and flavonoids, which give it antioxidant characteristics.In skincare, this extract functions as an antioxidant — meaning it helps neutralise free radicals generated by UV exposure, pollution, and other environmental factors that can contribute to skin damage and premature ageing.

The extract's polyphenols and flavonoids work by donating electrons to free radicals, neutralising them before they can damage skin cells and collagen. This reduces oxidative stress — one of the key drivers of visible ageing and inflammation.Some evidence suggests compounds in Artemisia princeps may also have mild soothing properties, though the research on this mechanism in skincare remains limited.

Artemisia princeps extract is typically found as one of several active ingredients in serums, essences, or creams rather than as a standalone treatment. Use it as part of your routine antioxidant protection, ideally in the morning to defend against daily environmental stress, or in the evening as part of your repair routine. Layer it under moisturiser for best results.

Generally well-tolerated by most skin types. Those with plant sensitivities or allergies to Artemisia species should patch-test first, as cross-reactivity is possible.
