Acacia Catechu Leaf/Wood Powder

Acacia catechu leaf and wood powder is derived from the heartwood and foliage of Acacia catechu, a tree native to South Asia. The powder contains naturally occurring tannins and polyphenols, compounds known for their astringent and antioxidant properties. In skincare, it functions primarily as a skin conditioning agent.

The ingredient has a long history in traditional Ayurvedic and folk medicine practices, where it has been used for its purported astringent and antimicrobial qualities. Modern cosmetic formulations typically incorporate it in powdered form to leverage these properties.

The tannins present in acacia catechu interact with skin proteins, creating a mild astringent effect that can temporarily tighten skin and reduce the appearance of pores. This mechanism may also contribute to a slight reduction in sebum visibility on the skin surface.

The antioxidant polyphenols present in the powder may help neutralise free radicals, though the degree to which topical application delivers meaningful antioxidant benefit depends on formulation stability and skin penetration.

Acacia catechu powder is typically found in masks, exfoliants, and powder formulations rather than serums or creams. Use as directed by your specific product — often 1-2 times per week for masks. If you have very sensitive skin, start with patch testing to ensure tolerance, as tannin-rich ingredients can occasionally cause mild irritation in reactive skin types.
