Its interesting you mention elevated DHEA levels contributing to acne. I'm 31 and still having breakouts more than I should....not a pizza face by any means...but still have blackheads and whiteheads at times. The other day I found out my DHEA levels are 988.2, more than three times the high end of normal. Hopefully it'll come down once I figure out what's causing it.
This probably didn't helo you, just wanted to comment.
