What it is
A finely ground powder from the leaves of Cassia auriculata, a flowering shrub also known as tanner's cassia. The leaves contain flavonoids and tannins, which give the powder its potential antioxidant and astringent properties.
How it works
The flavonoids in the leaf powder act as antioxidants, helping to neutralize free radicals that can damage skin cells. The tannins provide mild astringent effects, which may help temporarily tighten the skin and reduce excess oil on the surface. In a mask or cleanser, the powder also provides gentle physical exfoliation.
Pros
Gentle antioxidant support
The flavonoids in cassia auriculata leaf powder help protect skin from free radical damage, which can contribute to premature aging.
Mild oil control
The natural tannins provide a gentle astringent effect, making it useful for those with oily skin who want to reduce shine without harsh chemicals.
Cons and cautions
Limited scientific backing
Most evidence for this ingredient comes from traditional use and a few lab studies, not large-scale human trials, so its benefits are not fully proven.
Potential for dryness
The astringent tannins can strip natural oils if used too often, which may lead to irritation or tightness, especially for dry or sensitive skin types.
Best for
- People with oily or combination skin looking for a gentle astringent
- Those interested in traditional Ayurvedic skincare ingredients
Use caution if
- Individuals with very dry or dehydrated skin, as the astringent effect may worsen dryness
