I'm naturally fair, and am considering using a sunbed in the run up to the wedding (in 84 days time). However, I've never actually used one before, and as I am aware of the long-term damage, was wondering if anyone could give me any answers to some of the questions I have: Do I have to prep my skin beforehand or afterwards? How often should I use the beds and for how long in one sitting? Any advice or tips much appreciated! Thanks!
