When using a steamer, when should you turn on the ozone switch?

Turning on the ozone switch after steam is visible is appropriate because ozone acts as a disinfectant and an antibacterial agent, enhancing the benefits of the steam treatment without unnecessary exposure to ozone before steam is directed to the skin.

When steam is visible, it indicates that the steamer is adequately warmed up and generating a consistent flow of steam. Activating the ozone at this point allows for the benefits of both the steam and the ozone to work in conjunction, promoting skin hydration and cleanliness head-on. Using ozone prematurely could lead to waste or potential irritation, as the ozone would not be effectively working with the steam to treat the skin.

In contrast, the other options may suggest improper timing regarding the effects of ozone on the skin or the treatment experience. Turning on the ozone before steam is visible might fail to maximize its benefits. Waiting until the client feels warm or starting immediately before treatment could also lead to a less effective experience as patients may not receive the full therapeutic benefits that can be achieved by timing the ozone switch with the steam process correctly.
