What it is
An extract derived from the bark of Platanus occidentalis, a large deciduous tree native to North America. The bark is processed to concentrate its naturally occurring compounds, including tannins and flavonoids.
How it works
The extract's antioxidant compounds help neutralize free radicals, which are unstable molecules that can damage skin cells. Its tannins may also provide mild astringent and soothing effects, helping to calm redness and irritation when applied topically.
Pros
Gentle soothing potential
Early research suggests sycamore bark extract may help calm skin redness and irritation, making it a good option for sensitive skin routines.
Natural antioxidant source
The extract contains flavonoids and other compounds that can help protect skin from free radical damage caused by pollution and UV exposure.
Cons and cautions
Limited research
Most evidence for sycamore bark extract comes from lab studies, not large human trials, so its real-world benefits are not yet fully confirmed.
Lower potency than alternatives
Compared to well-studied antioxidants like vitamin C or ferulic acid, sycamore bark extract is likely less potent and may not deliver dramatic anti-aging results.
Best for
- People with sensitive or easily irritated skin
- Those looking for a gentle, natural antioxidant ingredient
Use caution if
- Individuals with known allergies to Platanus species (plane trees)
