You are not alone! A few weeks ago I too noticed this brown mark on my forehead. Today I saw a photo I took during Memorial Day Weekend and that mark was noticeable, since my face was at an angle it seems that the sun shined right onto my face! Anyway, I am trying to figure out what this might be....I hope someone responds.

I started to notice the spot when my friends started asking me what happened to my forehead. It looks almost bruiselike and if i stretch it(my skin) out it appears to have tiny bumps in it, it doesnt hurt and sometimes it is dry feeling. i dont tan i dont have children and in not expecting a baby. i also do not take hormone therapy or birth controll. i dont know what to do. makeup does nothing for it.
