Ingredient review
Greyia Leaf Extract
INCI: Greyia Radlkoferi Leaf Extract
A gentle botanical extract with antioxidant potential, but research is limited and benefits are not yet well-established.
In plain English
Greyia leaf extract comes from a South African shrub. In skincare, it's used to provide antioxidant protection, meaning it may help shield your skin from damage caused by environmental stressors like pollution. It's also thought to have soothing properties, which could calm minor irritation. However, there isn't much scientific research on this specific extract, so its effectiveness is not as proven as more common ingredients like green tea or vitamin C.

What it is
An extract derived from the leaves of Greyia radlkoferi, a plant native to South Africa. It contains various plant compounds, including flavonoids and tannins, which are known for their antioxidant activity.
How it works
The flavonoids and other polyphenols in the extract can neutralize free radicals, unstable molecules that can damage skin cells and accelerate aging. This antioxidant action helps protect the skin from oxidative stress. The tannins may also provide mild astringent and soothing effects, potentially reducing redness or irritation.
Pros
Gentle antioxidant
Provides a mild level of antioxidant protection that can help defend skin from daily environmental damage without causing irritation.
Soothing potential
May help calm minor skin redness or sensitivity, making it a good addition for those with reactive skin.
Cons and cautions
Limited research
There is very little published scientific data on Greyia radlkoferi leaf extract specifically for cosmetic use, so its benefits are not well-documented.
Unproven efficacy
Compared to well-studied antioxidants like vitamin C or ferulic acid, the effectiveness of this extract is uncertain and may vary by product formulation.
