Nothing, including bronzer, is required to be utilized prior to tanning. Because you should avoid using any type of lotion before tanning, and it would be best if you cleansed yourself well, as this would help you eliminate any type of lotion remained on the body. However, some people choose to use a little bit of tanning lotion as a mask before their session to protect themselves from the sun more so than what normal sunscreen would offer. After your tan has completely dried, you can apply another layer of lotion to enhance the look of your tan further.
