What it is
Quercus Acuta Fruit Extract is derived from the acorns of the Japanese evergreen oak and, like other oak materials, supplies tannins and phenolic compounds with antioxidant and astringent character. It is used as a supporting botanical for a conditioned skin feel rather than as a defined active, and it does not contribute UV filtration. It is typically present at low concentrations.
Safety & warnings
Acorn and oak fruit extracts are generally well tolerated at cosmetic use levels. Their tannin content gives mild astringency, which may feel tightening only in concentrated form; no notable allergen or comedogenicity concern is associated with this ingredient.
Origin & sourcing
Natural, plant-derived from the fruit (acorns) of Quercus acuta, an evergreen oak native to East Asia, including Japan and Korea; the acorns are extracted to recover their soluble polyphenolic fraction.
