Microcitrus Australasica Fruit Extract

Microcitrus australasica, commonly known as finger lime, is a small citrus fruit native to Australia. The fruit extract contains vitamin C, flavonoids, and organic acids that contribute to its skincare profile.In cosmetics, this extract functions primarily as an antioxidant and skin conditioning agent. It is used in small concentrations, typically as part of a broader formulation rather than as a hero ingredient.

The extract's antioxidant effects come from flavonoids and vitamin C present in the fruit. These compounds help neutralise free radicals that can contribute to visible ageing and skin stress.The organic acids in the extract may offer gentle exfoliating properties, though concentrations in skincare are typically too low for significant chemical exfoliation.

This extract is rarely a standalone active; it typically appears as a supporting ingredient within serums, essences, or moisturisers. Use as directed within your chosen formulation, and combine with proven actives such as vitamin C or niacinamide if targeting specific concerns like dullness or sensitivity.

Generally well-tolerated. As with all citrus-derived ingredients, there is a theoretical risk of photosensitivity in sensitive individuals; use sunscreen during the day.
