I have really short, sparse lashes so I've tried everything. This is the first serum I've repurchased. I am just getting used to waking up make-up free, and still looking this good. My lash length and volume are even better than they were 20 years ago!

I’ve been using this every night for about a month and my lashes look so much healthier. They feel stronger, less brittle, and my mascara goes on way better now.

It doesn’t sting my eyes or feel oily, and the applicator makes it easy to apply right along the lash line. Definitely part of my nightly routine now.
