I was skeptical about another brow serum, but the peptide and vegan keratin combo really delivers—my lashes look noticeably thicker after a month of nightly use, and the brush makes application mess-free.

Three weeks in and my brows are already noticeably fluffier. The peptide and vegan keratin formula doesn't irritate my sensitive skin at all, and I love that one serum handles both brows and lashes.

I was a little skeptical about a 2-in-1 serum, but the vegan keratin formula feels light and absorbs fast. After about a month, my brows look noticeably fuller and my lash line has that feathery, thicker appearance I was hoping for.
