Break out on face

Hello
I'm 8 months out.Im having terrible break outs on my face.What vitamin could I be lacking?My son's PKU doc thinks its Zinc or vitamin E or B-12.My last bloodwork was fine as far as iron and the regular bariatric blood work.The derm thinks it's my psoriasis wich does get worse in winter.Im just not sure.Any suggestions?

 It's pretty common with rapid weight loss. You are releasing those hormones from their fat cells.  I know when I lose 5 pounds I'm gonna break out. Then it goes away until the next 5.

HI IM ONE MONTH OUT TODAY, AND I NEVER HAD ANY BREAK OUTS ON MY FACE AND NOW ITS LIKE IM A TEENAGER ALL OVER AGAIN !!!!!
