Ingredient review
Angelica Keiskei Root Extract
INCI: Angelica Keiskei Root Extract
A gentle botanical extract with antioxidant potential, but research on its cosmetic benefits is still limited.
In plain English
Angelica keiskei root extract comes from a plant called ashitaba, which is native to Japan. In skincare, it is used mainly for its antioxidant activity, meaning it can help protect skin from damage caused by environmental stressors like pollution and UV rays. It also has some soothing properties, which may help calm irritated skin. However, most of the research on this ingredient has been done in labs or on animals, so we don't yet have strong evidence for how well it works on human skin in everyday products.

What it is
Angelica keiskei root extract is a natural plant extract obtained from the root of the Angelica keiskei plant, also known as ashitaba. It contains compounds like chalcones and flavonoids, which are believed to have antioxidant and anti-inflammatory effects.
How it works
In a cosmetic product, Angelica keiskei root extract works primarily by donating electrons to neutralize free radicals, which are unstable molecules that can damage skin cells and accelerate aging. Its flavonoids may also help reduce the production of inflammatory signals in the skin, leading to a calming effect.
Pros
Gentle antioxidant
Provides a mild level of antioxidant protection, which can help defend skin from daily environmental damage without causing irritation.
Soothing potential
Contains compounds that may help calm redness and sensitivity, making it a good option for reactive skin types.
Cons and cautions
Limited human research
Most studies on Angelica keiskei have been conducted in test tubes or on animals, so we don't have strong evidence that it works as well in human skin care products.

As a member of the Apiaceae plant family, it may cause allergic reactions in people sensitive to related plants like celery or carrots.
