I had recently used a Sex Toy with too little lubrication and my foreskin had become irritated from it. 2 Days later the Irritation was gone but since then, it seems about 1/3 of my Foreskin had lost some pigment. It has been maybe 6 weeks and still has a very pale area. Aside from the loss of Pigment there is no other visible issues and there is no discomfort, save for my worry over this. I Have poor medical insurance so have to save to make a Doctor Visit.

Any thoughts to what this could be? Or why the pigment faded after the Irritation?
