Psoriasis to Acute Dermatitis…Biologics?

So i had psoriasis for many years with coverage throughout and it was increasing year by year, every winter new patches in new areas would emerge, however last winter something crazy happened it all went away leaving behind only discoloured skin and instead i got acute dermatitis with extreme uncontrollable itching.

Would going on biologics now be a good option for me? Or should i find other ways to calm down the dermatitis since the psoriasis is gone, is it possible that the psoriasis patches could back instead if i went on biologics, looking at the overall unique situation what would you advise.
