Started to work overnight!!!
I was nervous to try this product because I read that it stings and it has the typical strong tea tree oil smell. My eyes were already irritated due to blepharitis that I didn't know I had until one month ago.  I read somewhere to treat for Demodex no matter what, because if you have blepharitis, a high percentage of people also have Demodex.  Never heard of Demodex before either!  I did have some stinging on my eyelids with my first application even after rinsing with water twice. My eyes felt better and even looked better the very next day. This product works for bleph and Demodex. I'm on day two. The second day application did not sting. Feeling more comfortable with it today. Twice a day is recommended.
