Fake tanning after sunbed?

[JadaDaisy]

So I’ve been going on the sunbed (still yet to develop a tan though) but I’m not tanned yet and I have something coming up, so I want to fake tan for it. But I’m wondering, will this put my sunbed sessions to waste, when i exfoliate the fake tan off, because wont it exfoliate my real sunbed “tan” off too??? Then I’ll have to start over from being completely pale?
