I regularly use st tropez express and leave on 2-3 hours, sometimes use the in shower one as a top up when rinsing it off.
I’m going on a special holiday soon, and just thought is it better to do a 3 hour one or maybe leave on 1-2 hrs then do it again so 2 coats?
Also does everyones fake tan come off as soon as you step into the sea/pool?
