Ingredient review
Carya Ovata Bark Extract
INCI: Carya Ovata Bark Extract
A gentle botanical extract with antioxidant potential, but research is limited and benefits are not yet well-established.
In plain English
This is an extract from the bark of the shagbark hickory tree, a type of hickory native to North America. In skincare, it is used mainly for its antioxidant properties, which means it may help protect your skin from damage caused by environmental stressors like pollution and UV rays. However, there is not a lot of scientific research specifically on this extract, so its effects are not as well-understood as more common ingredients like vitamin C or green tea.

What it is
A natural plant extract derived from the bark of Carya ovata, commonly known as shagbark hickory. It contains various compounds like tannins and flavonoids that can act as antioxidants.
How it works
The extract works by donating electrons to neutralize free radicals, which are unstable molecules that can damage skin cells and accelerate aging. It may also have mild astringent properties due to its tannin content, which can temporarily tighten the skin.
