When poison ivy has been oozing why does it turn yellow when it dries?

I have poison ivy currently and i've noticed that if it is ooozing and then dries up, it turns yellow, why does it turn yellow and not clear or something?





Also if my poison ivy has gotten better after almost a week after using anti itch gel that i think is supposed to dry it up should I see a doctor.





I am very very allergic to it and it has spread onto my face from my arm in less than 2-3 days

if it is crusty yellow you may have impetigo on top of the poison ivy rash which would require antibiotics. Also, for poison ivy itch zyrtec would be better along with atarax if the itching is really bad
