Mechanism of action

Hydrogen peroxide penetrates microbial cell membranes and generates free radicals that damage cellular components, DNA, and proteins, leading to cell death. It also mechanically cleanses wounds by releasing oxygen bubbles that help remove debris and necrotic tissue. The antimicrobial effect is broad-spectrum, affecting bacteria, fungi, and some viruses.
