I have the same problem as described by the 1st person. I get black spots on my cheeks, and only my cheeks, after sweating or getting flush in the face.
I've had this problem for a few years, probably starting in college, but never too severly, only once in a while. Now I get the black spots almost every time I do physical activity or go tanning - heat seems to be the biggest cause of the problem.
People suggested that it was dirt being secreted from my pores, but I never believed this, especially because the black spots can appear soon after I just finish showering.
I have searched online many times for information on this problem, but have yet to find anything. I'm glad I finally found something related to the problem.
I am also rarely sick, and have not gone to the doctor for this problem, but am looking to go soon. I guess I would have to take photos or show them in person what the spots look like, and maybe have them scrape off a sample to look at under a microscope.
I think the problem may be caused by toxins being secreted from the pores on my cheeks, and this may be due to a problem with one of my internl organs that I am not aware of yet, I dont know...
If anyone has any experience with this problem, or any solutions I'd really appreciate any information. Thanks.
