With Lupus is a Blue Peel Dangerous?

I don't recommend any treatments in patients who have low WBC counts that compromise the integrity of the skin barrier. I would get clearance from an immunologist before you seek such treatments. 

The risks of an Obagi Blue Peel are low but scabbing, bleeding, and infection are among these risks. Having a low platelet count will increase your risk of bleeding. Having a low WBC count will certainly increase your risk of infection. Therefore doing anything that will compromise the integrity of your skin and increase the risk of bleeding or infection is a risk not worth taking. I would recommend against your having an Obagi Blue Peel until your WBC count and platelet levels return to normal.
