A few weeks ago I developed some red spots on my upper chest area, centered mostly around
the front of
the shoulders and pectoral region.
The red marks would look like tiny red
acne lesions, but they did not respond to any of the acne medication that I tried to use on them (benzoyl peroxide, etc). The marks would spread more and more. They did not itch, they were not painful, and they did not come to a head.
