Aspalathus linearis Leaf Extract

Aspalathus linearis Leaf Extract, derived from the fermented or unfermented leaves of the South African rooibos plant, is exceptionally rich in unique polyphenols including aspalathin and nothofagin, flavonoids found virtually nowhere else in nature. These compounds deliver potent antioxidant activity that helps neutralize free radicals, soothe inflammation, and support skin barrier function, making the extract particularly valued in sensitive and anti-aging formulations. Formulators are drawn to rooibos extract not only for its efficacy but also for its naturally low tannin content compared to other botanical extracts, reducing the risk of skin irritation while still delivering meaningful protective and conditioning benefits.
