I can use this even with my sensitive eyes and allergies.
I have sensitive skin and eyes.  Without the right mascara my eyes itch and my eyelids get a reaction.  I've wanted to get a lash growth serum but was reluctant because of my eye allergies.  This does not cause any reactions. I put it on both top and bottom eyelashes with no issues. I have only used it for a few days so I can't say if it works, yet.  I've taken before pics and even though it states to use it for a 30 day period I will post and update after two weeks to see the progress.
