I tend to get breakouts around my mouth and chin and on the back of my neck (under my hair) after several days of diving. Does anyone else experience this? Nowhere else on my face or body. I know there's a thing called skin dcs but that's not it. I get this almost every time I dive for a week or more. I'm a very safe, experienced diver and there are no other symptoms and it hasn't ever occured anywhere else on my body. Maybe the neck can be caused by irritation from my wetsuit, but that doesn't explain around my mouth and chin? If it is an allergy to something in the wetsuit, woudn't I experience it on other parts of my body? And can you be allergic to your reg? Even if, the reg doesn't acutally touch my face, only the bubbles. It doesn't occur until about the 3rd day of diving and is very bothersome, unsightly and embarrasing. Any suggestions or clues?
