Do lash serums work?

Winter, with its frosty chill or soggy gloom as we have this morning in Norfolk, when you feel trapped a little in your cosy caves, is the time to discover new tricks as far as I'm concerned.
I am trying 'fanomenal' the lash serum from no 7 to see if it really increases lash growth as  my previous attempts at false lashes or inserts leave my looking like Lilly Savage at the end of a heavy club night!
The whole lash growth serum idea came from a product called bimatoprost, a treatment for glaucoma with the side effect of increasing lash growth (not without its own possible side effects) this was developed by a company called Latisse into a quite pricey  but its not easy to find out if this is in the new growth serums in any form so, I shall continue my trial and post results.....prepare for a bit of batting in eight weeks!
