What it is
This ingredient is derived from the seeds of yuzu (Citrus junos), an aromatic East Asian citrus. Yuzu seeds are traditionally noted for their mucilage and lipid content, and the extract is used in skincare for conditioning and antioxidant-associated positioning. It appears as a regional botanical particularly in Japanese and Korean formulations and is typically used at low levels.
Safety & warnings
Generally well tolerated at cosmetic use levels. Seed-derived material is lower in volatile fragrance constituents than peel oil and does not carry the cold-pressed-peel phototoxicity concern. As with any botanical, sensitization is possible in predisposed individuals, so patch testing is reasonable for reactive skin.
Origin & sourcing
Plant-derived, extracted from the seeds of yuzu (Citrus junos), a citrus prominent in Japan and Korea.
