Castanea Crenata Pellicle Extract

Castanea crenata pellicle extract is derived from the thin, papery skin (pellicle) surrounding Japanese chestnuts. This botanical ingredient is rich in polyphenols and tannins, compounds known for their antioxidant capacity.In skincare formulations, it functions primarily as an antioxidant and astringent. The antioxidant properties help neutralise free radicals, whilst the astringent action may help tighten and tone the skin's appearance.

The tannins and polyphenols in chestnut pellicle extract work as antioxidants by donating electrons to unstable free radicals, rendering them harmless. This helps slow oxidative damage to skin cells and may support the skin's natural defence mechanisms.The astringent action stems from the tannin content, which can bind to skin proteins and temporarily contract skin tissue, creating a tightening sensation and a more refined appearance of pores.

This ingredient is typically incorporated into serums, toners, and astringent formulations. It tends to work well in lighter, water-based products where its antioxidant and astringent properties can be effectively delivered. Use as directed by the product instructions; if using multiple antioxidant ingredients, ensure the routine remains balanced and non-irritating.

Castanea crenata pellicle extract is generally well-tolerated. Those with sensitivities to tannins or plant extracts should patch-test first, as astringent ingredients can occasionally cause mild dryness or irritation in sensitive skin.
