"All sufferers of EC report that they have a tendency to bite, pick, and lick their lips. However, the literature on the subject fails to notice the impact that these habits have had on the skin (Figure 1)."
That's not right. Many people on here have said that they've never done this. I didn't and would put my cause down to a number of other possibilities.
I would also say somewhere that the number of people who also have Fordyce's Spots is noticeably high. I think this needs major research.
The thing that keeps skin elastic and water-proof is sebum. Fordyce's Spots are caused by sebecaeous glands. There has to be a link!
