What it is
Pyrus Cydonia Seed Extract is derived from quince seeds, which are notably rich in polysaccharide mucilage that swells in water to form a smooth, hydrating gel. In formulations it can lend a soft, conditioned skin feel and a light film, and it is used as a supporting botanical rather than as an active. It does not filter UV radiation.
Safety & warnings
Quince seed extract is generally well tolerated and is not associated with significant allergenicity or comedogenicity at cosmetic use levels. As with any botanical, isolated sensitivity is possible but uncommon.
Origin & sourcing
Natural, plant-derived from the seeds of the quince shrub (a member of the Rosaceae family), here listed under the name Pyrus cydonia; the seeds are extracted, often in water, to release their characteristic mucilage.
History
Quince seed mucilage has a long traditional history as a thickener and skin-soothing preparation in folk cosmetics before its incorporation into modern formulations.
