Psoriasis and sunburn

Hi all, 6 months ago (August 2015) I went on holiday for a week. One day I went to the beach for the whole day and I forgot to put sun cream on (stupid I know)! This resulted in my arms and legs becoming sunburnt...and I mean really sunburnt! It was extremely painful on the days that followed. Even now, 6 months on, I still have a distinctive tan/burn line on my arms and legs (I have psoriasis on my arms and legs). I was using dovobet to manage my psoriasis and it was working very well, but then I stopped after I got sunburnt. Now I want to start managing my psoriasis again, I want to know if it's safe for me to use the dovobet on my, previously sunburnt but now healed, skin? Does anyone else have experience of getting sunburnt and then not knowing whether to apply the same topical cream that they were using beforehand? I would see my GP, but my health centre is extremely busy at the moment, currently a 3 week wait for an appointment! So I wanted to ask on here and see if anyone else has been in a similar situation and if I can get some advice. Thanks :)
