A member asked:

I've seen pictures in a text book of some people's pity. rosea. why is this rash occuring?

A doctor has provided 1 answer

Rosacea Cause: People with rosacea have too much of a molecule known as cathelicidin, and using mice and artificial cell culture techniques, they showed that this excess leads to rosacea symptoms. They have also shown that the overabundance of cathelicidin is the result of an excess of an enzyme in the facial skin.
