Citrus Junos Extract

Citrus junos extract comes from yuzu, a citrus fruit native to East Asia. The extract is typically derived from plant callus tissue and contains bioactive compounds including phenolic acids and flavonoids. Its primary function in skincare is to act as an antioxidant, helping to neutralise free radicals that can damage skin cells.The extract's key active compound appears to be 4-hydroxycinnamoyl-malate, a water-soluble phenolic substance that research suggests may have both antioxidant and skin-lightening properties.

Citrus junos extract works primarily through free-radical scavenging. Its phenolic compounds donate electrons to unstable free radicals, stabilising them and preventing them from damaging skin proteins and DNA. This antioxidant mechanism helps reduce oxidative stress, which is implicated in skin ageing and pigmentation disorders.The extract also appears to inhibit tyrosinase, an enzyme central to melanin synthesis. By reducing tyrosinase activity, it may help suppress melanin production in melanocytes, potentially supporting a more even complexion. Additionally, preliminary evidence suggest…

Citrus junos extract is typically found in serums, essences, and moisturisers where it works well alongside other antioxidants. There is no specific minimum or maximum concentration guidance established for consumer products. As with any antioxidant ingredient, it may offer better stability and efficacy when used consistently as part of a daily skincare routine. It pairs well with complementary actives such as vitamin C, niacinamide, or other polyphenol-rich extracts.

Citrus junos extract is generally considered well-tolerated, though formal safety data in humans is limited. Those with citrus sensitivity should exercise caution, though topical use is less likely to trigger systemic reactions than ingestion.
