I, too, bruise mainly on my forearms. It’s just awful! I can go to bed relatively clear and wake up with a new (and ugly) bruise that popped up overnight! My PC doc said the skin doesn’t really get thin, but the capillaries get closer to the surface (I think that’s how he explained it).
Anyway, he said nothing about sun exposure, but recommended Dermend. I’ve been using it for years and it seems to be the only thing that makes a difference. They’ll FINALLY fade, but they take their sweet time doing so. Of course, by the time they do fade, two more have popped up! Very frustrating.
I guess it could be worse….my legs could also be affected. So far, at age 74, the
bruising has been confined to my forearms, and my right forearm seems to be more vulnerable than my left. Every now and then, I might bruise on my hands, as well.
My dermatologist recently told me if he had the solution, he’d be a rich man!
