Red 'line' of skin on forehead.
Ever since I can remember, I have had a red tinged line of skin running down the middle of my forehead. It seems to begin at the hairline and end between the eyebrows.
It seems to have gotten worse during my teenage years, I am now 24. It can appear redder at certain times, in hot atmospheres etc. I have a rosy complexion anyway so my cheeks do similar things!
This line is quite noticeable, and I have basically kept longish hair for most of my life so that I can just leave it hang over and not show the redness. The area has never been sore or itchy at all. It feels maybe harder and slightly rougher than the rest of the skin around it.
I have asked a few doctor about this and basically none of them have ever provided any sort of proper explanation or treatments, they've often told me to just deal with it and leave it if it's not causing harm, which I have done, but at the same time it would be nice to know if there's anything I can do to lessen it's effect?
I have provided a photo that sort of shows it up.
Any help or advice would be very much appreciated.
