Backhousia Citriodora Leaf Extract

Backhousia citriodora leaf extract comes from the lemon myrtle plant, native to Australia. The extract is obtained from the leaves and contains volatile compounds and phenolic constituents that give it characteristic astringent and skin-conditioning properties.In skincare formulations, this ingredient is used primarily for its astringent action—meaning it may help tighten the appearance of pores and reduce excess surface oil—and its skin-conditioning role, which supports the skin's overall feel and appearance.

The astringent effect is thought to work through the tannins and other polyphenolic compounds in the extract, which can create a mild tightening sensation on the skin's surface. This may temporarily reduce the appearance of pores and help manage oily skin behaviour.The skin-conditioning properties stem from the extract's volatile oils and other natural constituents, which can help maintain skin hydration and support a smoother skin texture.

This ingredient is typically found in toners, essences, and light serums at low concentrations. Use as directed in your chosen product—usually morning and evening for astringent products. Since it may have a drying effect, those with sensitive or dry skin should introduce it gradually and monitor how their skin responds. It pairs well with hydrating ingredients to balance its astringent nature.

Generally well-tolerated in cosmetic products. Astringent ingredients may irritate sensitive skin, so patch test first if you have reactive skin or known sensitivities to botanical extracts.
