The best eyelash serum

I’m looking for an eyelash serum that does not cause orbital fat loss, which I realize is a difficult ask. I’ve heard that with some eyelash serums, if you stop using it your eyelashes will fall out. I would like an eyelash serum that avoids that. I’d also like one that makes my eyelashes longer AND thicker. If you have an eyelash serum that fits this criteria, please comment!!
