I love this eyelash serum. It definitely feels different from the other serums I've used in the past. I started seeing results almost afrer 2 weeks.
I ordered the subscription order by mistake, but in hind-sight, I'm glad I did cuz this is the best serum I've used. They have an option to buy subscription or one time purchase on their order page. I think people might be missing that (just like I did)
