Have tolerated for many years small red spots on forearms, which redden considerably when exposed to sun. I enjoy the outdoors. When exposed, they itch, and some flaking of skin around the spots. Turn noticably bright red when exposed to direct sun. In construction, work outdoors a lot. Also on upper arms, though not exposed to sun as much. 10 years ago was prescribed Carac cream (spelling?) to no avail, also very expensive. Also deal with some pigmentation loss on spots on back due to sweating (tropical acne it was called many years ago) used coal tar shampoo, didn't seem to help much. Dime to nickel size maybe 8-10 spots. But red spots on arms are the most annoying, and unsightly. Very much would appreciate your advice. Thanks
