Buy It

I've been using it on and off for about 3 weeks now and although I don't have thin lashes, unless I curled them and brushed them, they didn't "pop" per say. NOW... I don't have to do either and they POP. :) -- adding I do not wear makeup so I do apply it during the day after my shower.

Great results so far

Love the IGK Lash & Brow Serum! Noticed fuller, thicker brows and longer lashes in just a few weeks. It's easy to apply and gentle on my sensitive eyes.
