Avoid the temptation of trying to add an extra few minutes to your tanning session. Not only do you risk over-exposure, but you are actually slowing the process down. When your skin starts to turn red from over-exposure, the tanning process shuts down. You will tan more efficiently if you shorten your session time and go more often. Then once you get the tan you want, you can increase the time between session in order to maintain what you have. And don’t forget to use a lotion specifically designed for sunbed use.
