So here's what I need help with. I have a 8 year old Paint mare, she sun burns extremely easy. Little history on the mare. My brother bought her as a 2 year old and has had her til she was 7, the whole time he had her they never used on done anything for her sunburn or to prevent it (No I don't believe this is right but she WAS NOT my horse at the time therefore I had no say so). He sold her at 7 and the guy that had her would put her in the stall all day and turn her out at night. I don't think he done anything other then stall her. Well here a a few months ago her offered her to me (he asked my brother first but he has gotten out of horses and didn't want to buy her back) well I have sentimental attachment to her, she was one of the last horses that my brother broke and trained before he stopped doing it so I sold the horse I had at the time and bought her but he said he would keep her there til Aug., which was last month and he brought her to me. So the only reason I went into that big long story was the main points of she has always sunburnt but nothing was done about it for the time my brother owned her. And this is the only horse I have ever owned that sun burns so I need to know what to put on her (as far as sheets? Or blankets or something that would keep her from burning) or if there is something I should use, like an oinment or something. As of right now she is in a field that has a lot of shade and I put I fly mask on her and peoples sun block on her nose to keep it from burning (it seems to be the place she burns the easiest and most). I have no access at all to a stall so that's not an option. But any other advice would be greatly appreciated.
Also if I take her for a trail ride should I put something on her face? Or would it be fine then?
Here are some pictures of her.
The pink above her eye is where she got burnt.
And the other side.
You can kinda see where her nose has been burnt here.
