Citrus Paradisi (Grapefruit) Seed Extract
What is Citrus Paradisi (Grapefruit) Seed Extract?
Citrus Paradisi (Grapefruit) Seed Extract is derived from the seeds of the grapefruit tree, Citrus paradisi, a subtropical citrus hybrid originating from Barbados. The seeds undergo grinding and extraction, typically with water or glycerin, to produce a concentrate containing bioflavonoids like naringin, limonoids, and phenolic compounds. In cosmetics, it falls under botanical extracts and appears in cleansers, toners, serums, and hair care products. It functions primarily through its polyphenolic content, which may offer antimicrobial effects to help preserve formulations and support skin microbiome balance. Additionally, its antioxidant properties can neutralize free radicals, while astringent qualities promote a smoother skin feel. Though popular in natural products, its efficacy relies on extraction methods and composition variability.
