Citrus Junos Seed Extract

Citrus Junos Seed Extract comes from yuzu, a citrus fruit native to East Asia. The extract is rich in polyphenols and contains compounds called limonoids, which give it antioxidant properties. In skincare formulations, it appears in very small amounts (found in roughly 0.1% of products) and is valued primarily for its ability to neutralise free radicals.The seed extract is particularly interesting because research has identified nomilin, a specific compound within it that may influence melanin production. This makes it relevant for those interested in addressing uneven pigmentation.

Citrus Junos Seed Extract works primarily as an antioxidant, meaning its compounds can donate electrons to neutralise free radicals—unstable molecules that damage skin cells and contribute to visible ageing. This protective mechanism helps preserve skin integrity and may reduce inflammation.The limonoid fraction, particularly nomilin, appears to work through a different pathway. Research suggests it inhibits tyrosinase, the enzyme responsible for converting the amino acid tyrosine into melanin. By slowing this enzymatic step, it may help reduce hyperpigmentation and support a more even comp…

Citrus Junos Seed Extract is typically used as part of a broader formulation rather than as a standalone active, given its low concentration in most products. It works well alongside other antioxidants and can be used daily as part of your regular skincare routine. For concerns such as uneven tone, consistency over time is more important than frequency.

Citrus Junos Seed Extract is generally well-tolerated in skincare products. As with all citrus-derived ingredients, patch test if you have sensitive skin or citrus sensitivities, though reactions are uncommon at the low concentrations used cosmetically.
