Campsis Grandiflora Flower Extract

Campsis grandiflora flower extract is derived from the trumpet vine flower, a traditional plant used in East Asian skincare. The extract is obtained through solvent extraction, which isolates the active compounds responsible for its antioxidant properties.In skincare formulations, this ingredient functions primarily as an antioxidant and skin conditioner. Antioxidants work to neutralise free radicals—unstable molecules that can damage skin cells and contribute to signs of ageing and inflammation.

The extract contains compounds that act as free radical scavengers. When applied to skin, these compounds seek out and neutralise unstable molecules before they can damage cell structures and proteins. This protective action may help reduce inflammation and support the skin's natural resilience.In laboratory studies, the extract has demonstrated the ability to protect skin cells from oxidative damage by inhibiting harmful enzyme release and preventing DNA fragmentation—markers of cellular stress.

This ingredient is typically found in serums, essences and moisturisers as part of a broader antioxidant complex. For best results, use it as part of a consistent routine alongside sunscreen (which prevents new free radical formation) and other complementary actives. Layer it under heavier creams if using in a serum form.

Campsis grandiflora flower extract is generally well-tolerated in skincare products. As with any plant extract, patch testing is advisable for those with known sensitivities to botanical ingredients or a history of contact dermatitis.
