Sun after laser?

Does anyone know how soon it is ok to go in the sun after a gentleLase treatment (which, for those of you who have read my posts - is now the “clean up” treatment to my bad lightsheer treatment when I was stuck out of town for the summer & couldn’t see my regular person). I am now back home.

I was thinking to run outside but then my shoulders (the main target area) would be totally hit by the rays… I could use a sunscreen, but I also am trying to get a little tan… (I’ll probably use a low SPF one - but maybe still it’s a bad idea?) If so - for how long? Just long enough for the redness to go or longer?

Thanks!
