One of the reasons people love high intensity tanning is the element of time. , high-pressure tanning can get you that base tan in around five sessions. While a low-pressure tanning bed requires up to 15 sessions to create a base tan, and then 2 sessions a week to maintain it. That's roughly a quarter of the time -- a huge savings of time and money. The reason behind this is that there is less UVB light used, which allows your skin to stay moisturized and your tan to last longer.
