I had a growth on my forehead where I was allergic to something and had touched my forehead with my hand too often. It itched horribly which made it worse, when I scratched it. I went to the dermatologist for some cream or something to make it stop itching and we got in an argument as he wanted me to stop scratching, LOL!

But he taught me behavioral techniques to keep my hand away from my face which I imagine you could teach yourself to keep away from your eyelashes and plucking.
