Non-irritating
I applied this right away, to just one eye, to be able to post intitial thoughts.  I received a different lash serum I will be using on the other eye.  As for this one, it has a great little slim brush for precise application.  It didn't cause any irritation and felt just like an oil.  There was no scent that I noticed.  I will update in 14 days to share my results and the results of my comparison!
