Sodium usnate is a salt derived from usnic acid, a compound naturally found in certain lichens. It's used in skincare products for its ability to fight bacteria and help control excess oil production on the skin.

This ingredient works as an antimicrobial agent to help prevent bacterial growth and as an antiseborrhoeic to reduce excess sebum production, making it useful in products designed to treat oily or acne-prone skin.
