ACACIA FARNESIANA STEM BARK EXTRACT.

Optional CAS 89958-31-6 / SKIN CONDITIONING

A botanical extract derived from sweet acacia stem bark that delivers skin-conditioning benefits through its rich tannin content. While primarily valued for its natural astringent properties and gentle fragrance, this extract lacks substantial clinical validation for advanced dermatological applications.

Summary

skin conditioning astringent fragrance antioxidant

Science

Mechanism of Action

Functions through tannins, gallic acid, and methyl gallate compounds that provide free radical scavenging activity and metal ion chelation. The astringent tannins temporarily tighten skin while offering anti-inflammatory benefits by modulating COX enzymes and interleukin pathways.
