What material are high frequency rods typically made of?

High frequency rods are typically made of glass. The reason glass is used for these rods is due to its ability to withstand significant electrical current while ensuring safe contact with the skin. Glass allows for effective transmission of the high frequency electrical currents during treatments, which are intended to promote various skin benefits such as improved circulation, increased collagen production, and enhanced product absorption.

Additionally, the design of glass rods can facilitate different treatment techniques, as they can be shaped in various ways to cater to specific areas of the face or body. This material is also easy to clean and sterilize, which is crucial in esthetics to maintain hygiene standards. Thus, the choice of glass is particularly important for the functionality and safety of high frequency treatments in esthetic practices.
