What it is

An extract made from the leaves of the Cassia angustifolia plant, a shrub native to parts of Africa and Asia. It contains compounds like flavonoids and anthraquinones that have antioxidant and anti-inflammatory properties.

How it works

The flavonoids in the extract help neutralize free radicals, which can damage skin cells and accelerate aging. Its anti-inflammatory compounds may reduce redness and calm irritation when applied topically.

Pros

Cons and cautions
