Re: Don't know what else to try
About the humid environment thing -- I definitely think it brings out anything that is lurking in your skin! I'm usually not outdoors at all during the summer, but I just recently went to a bonfire outside. Before I left the house, I had these two "underground" cysts that had been on my chin for weeks and weren't doing ANYTHING.. just kinda laying there dormant. Well after a few hours around the bonfire, I could feel my cysts kinda feeling tingly (it was VERY humid out).. when I came home about five hours later, these two cysts that I never thought were going to go away were totally up to the surface, red, inflamed, and basically looking really disgusting.
Humidity causes some people to get really oily also, that could be another problem. Acne around the jawline and chin is usually do to stress and/or hormones.. perhaps this new job (along with the humidity) is stressing you out??
