Bougainvillea Glabra Flower Extract

Bougainvillea glabra flower extract is derived from the flowers of the bougainvillea plant, a tropical flowering shrub. The extract is obtained through solvent extraction methods and contains a range of polyphenolic compounds, including catechin and gallic acid, which are naturally occurring antioxidants.In skincare formulations, this ingredient is primarily used as a skin conditioning agent. Its polyphenol content suggests potential benefits related to antioxidant activity, though research on its specific application in cosmetics remains limited.

Bougainvillea flower extract contains polyphenolic compounds that function as antioxidants. These molecules can neutralise free radicals—unstable compounds that contribute to skin ageing and irritation—by donating electrons and stabilising them.In laboratory settings, the extract has shown potential to inhibit tyrosinase, the enzyme responsible for melanin synthesis. However, the concentration required for this effect in a topical product and the degree to which it penetrates the skin barrier remain unclear.

Bougainvillea flower extract is typically found in serums, essences, and moisturisers. As with any plant-derived ingredient, patch testing is advisable before routine use, particularly for those with sensitive skin. The ingredient is usually incorporated into formulations alongside other active ingredients, so benefits may be attributed to the overall formula rather than this component alone.

Bougainvillea flower extract is generally considered safe for topical use and is well-tolerated by most skin types. Those with known sensitivity to botanical extracts should perform a patch test first.
