Assuming you've never used a tanning bed before, there are a few things you should do to prepare for your first session. First, you'll need to purchase a bottle of tanning lotion. Be sure to read the labels carefully and choose a lotion that is designed for use in a tanning bed. Next, you'll need to exfoliate your skin. This will help to remove any dead skin cells that could prevent the tanning lotion from working properly. Finally, make sure to shave or wax any unwanted hair from your body. This will help to ensure that your tan is even and smooth.
