What Is Citrus Medica Flower Extract?
Citrus medica flower extract is derived from the flowers of the citrus medica plant (fingered citron), a citrus species native to Asia. The extract is obtained through solvent extraction methods and contains naturally occurring compounds including phenolic compounds and flavonoids, which contribute to its biological activity.
In skincare formulations, this ingredient functions as an antioxidant and skin conditioner. The antioxidant properties help neutralise free radicals that can contribute to skin ageing and oxidative stress, whilst the skin-conditioning aspect supports the overall feel and hydration of the product.
Benefits for Your Skin
How It Works
The bioactive compounds in citrus medica flower extract—primarily phenolic compounds and flavonoids—function as antioxidants by donating electrons to free radicals, stabilising them and preventing them from damaging skin cells. This process is known as free radical scavenging.
The conditioning properties work by forming a light protective layer on the skin surface and supporting the skin's natural moisture retention, which can improve overall skin texture and appearance.
Clinical Evidence & References
Research on citrus medica flower extract demonstrates measurable antioxidant activity in laboratory settings. Studies have shown that fermented preparations of the extract exhibit enhanced tyrosinase inhibition and antioxidative activity compared to non-fermented versions, suggesting that extraction and processing methods influence the ingredient's efficacy.
However, evidence specific to topical application in skincare formulations and observable effects on human skin remains limited. Most research has been conducted in vitro or on concentrated extracts rather than at typical cosmetic concentrations. Further clinical research on real-world skincare use would strengthen our understanding of its practical benefits.
Published Research
How to Use
Citrus medica flower extract is typically found in serums, moisturisers, and treatment products. As with any antioxidant ingredient, layering it with complementary actives—such as sunscreen during the day—optimises its protective benefits. The ingredient is generally stable in formulations but may perform best in products protected from direct light and heat exposure.
