End of psoriasis? White dots on body?

Hi, the angry part of psoriasis seems over for me. The red itchy angry part. I got a home uvb canopy just after the angry ness had started to subside to be honest as that was only time I could afford to finally get it. Now I’m left with non itchy body with white dots. It’s taking ages for the skin tone to even out. It’s like I have vitiligo now. I only get psoriasis episodes every other year and usually not left with these white marks allover this long after the angry phase. I’m a tanning type person so I have been on the odd sunbed and used tanning creams which I did on previous episodes that were finishing. This white vitiligo type phase doesn’t seem to be ending though :/ Anyone know if it ever will?
