Ozone (Antibacterial Action)

Ozone (O₃) is a reactive form of oxygen with well-known antiseptic and antibacterial properties. In a high-frequency facial device, a rapid alternating current passes through a sealed glass electrode and, where it meets the air at the skin surface, converts ambient oxygen into a small amount of therapeutic ozone.

That ozone is the active ingredient behind high frequency’s oldest use: treating acne. Applied over blemishes (often after extractions), the antibacterial action helps kill surface bacteria and dry and calm breakouts, while the gentle stimulation boosts local circulation. It is a simple, inexpensive, drug-free finishing step that has remained a staple of professional facials for over a century. The same device also offers an indirect mode for stimulating facial massage.

For clinics, ozone is the reason a low-cost high-frequency wand still earns its place as a reliable acne and post-extraction tool.
