Mechanism of action

BufferGel works by maintaining an acidic vaginal pH (≤3.8) through its buffering capacity, which inactivates HIV and reduces the viability of other sexually transmitted organisms. When used with a diaphragm, it provides both a physical barrier and chemical protection against pathogen transmission. The combination approach targets multiple mechanisms of infection prevention.
