Hello. Two days ago my forehead was all ok in the morning but in the evening I noticed light darkened patches on my forehead. The skin there was dry and like plasticy. Like it was detached from the skin underneath. There is no redness, itchiness or any discomfort. It's just dry and flaky, but the skin is not peeling off. It has happened once before few weeks later and cured within 4-5 days by itself. But this time there is a red/pink spot between my eyebrows also. It looks like internal blood clot like it hit by something, but there was no hit. There's no pain. Nothing. It's just weird. What could this be? I am nervous. Please tell me what is this. Please see the pictures I am attaching.
