for women, most of the time, it's hormonal.
also keep in mind that rosacea looks like acne. I had just turned 30, and wondered what the heck was going on!
I thought I had severe acne, and it turned out that I had rosacea, and of course, the treatment is completely different.
it's probably time to go to a dermatologist, and get it under control rather than trying to burn them off, thinking they're pimples.
