Hertz is the number of pulses delivered per what time period onto the skin?

Hertz (Hz) is defined as the unit of frequency in the International System of Units (SI) and represents the number of cycles or pulses per second. When discussing laser therapies and their application on the skin, it is crucial to understand that the frequency of pulse delivery, measured in Hertz, indicates how many times the laser emits a pulse in one second.

In this context, saying that a device operates at a certain frequency in Hertz informs you about the number of pulses produced every second, which is critical for determining treatment effectiveness and safety. The higher the Hertz, the more pulses are delivered, which may affect the overall treatment intensity and outcome on the skin. Thus, the correct time period associated with Hertz is seconds, distinguishing it from other time frames such as minutes or hours, which would not accurately represent the frequency of pulse delivery in this scenario.
