Science
Mechanism of Action
This complex functions as an antiperspirant by reacting with sweat, forming a temporary gel plug within the eccrine sweat ducts to prevent moisture from reaching the skin surface. It also possesses astringent properties and antimicrobial effects, which help reduce odor-causing bacteria.
