I was skeptical about how the results would turn out, but WOW! The lash serum actually works! I already had decently long lashes, but now they're even longer and fuller. This serum makes your lashes grow for longer, so I feel like I've got even more lashes than I previously did since they're not falling out early. I have sensitive skin and am allergic to almost everything, but this gave me zero issues! I highly recommend and will be purchasing again. I'm not even at maintenance use yet. I'm on week six and I'll be continuing to use daily for two more weeks.
