Smoke Tree Leaf Extract
INCI: Cotinus Coggygria Leaf Extract
A gentle plant extract with antioxidant and soothing potential, though human skin research is still emerging.
In plain English
Smoke tree leaf extract comes from the leaves of a shrub known for its fluffy, smoke-like flower clusters. In skincare, it's used mainly for its antioxidant content, which can help protect skin from environmental stress. Early research suggests it may also calm redness and support skin barrier function, but most evidence comes from lab studies rather than large human trials.

What it is
An extract made from the leaves of Cotinus coggygria, a plant native to southern Europe and Asia. It contains polyphenols, flavonoids, and tannins that give it antioxidant and astringent properties.
How it works
The polyphenols in smoke tree leaf extract neutralize free radicals, reducing oxidative stress on the skin. Its tannins may provide mild astringent effects, helping to tighten pores and reduce surface oiliness. Some compounds also appear to calm inflammatory responses in skin cells.
Pros
Antioxidant support
Helps protect skin from daily environmental stressors like pollution and UV exposure, which can lead to premature aging.
Soothing potential
Early research indicates it may calm redness and irritation, making it a good option for reactive skin types.
Cons and cautions
Limited human research
Most evidence comes from lab or animal studies; large-scale human trials are lacking, so effectiveness is not fully proven.
Possible drying effect
The natural tannins can be mildly astringent, which might be too drying for already parched or sensitive skin.
Best for
- Anyone looking for a gentle antioxidant to add to their routine
- People with oily or combination skin who want mild astringent benefits
Use caution if
- Those with very dry or compromised skin barriers should patch-test first due to potential astringent effects
