Our take
Is Castanea Crenata (Chestnut) Shell Extract a Good Ingredient?
Oil-control and antioxidant effects are suggested by its polyphenol and tannin content, but human evidence is limited, which is why it's rated Fair. Astringent tannins can also increase dryness or irritation, especially on sensitive or already dry skin.
What it does
Skin Benefits
May help curb surface shine and promote a more uniform appearance, providing a subtle clarifying boost for complexions prone to looking oily; data supporting these effects is limited.
Where you'll find it
Uses in Skincare & Cosmetics
Found in oil-control primers, gel moisturizers, and toners, and also used in clay masks designed for a mattified finish.
Before you use it
Safety
Can be mildly irritating or drying because of its astringent nature; patch test if skin is sensitive. No widely recognized regulatory restrictions at customary cosmetic use levels.
