I have gone through all 28 applications of Osmotics FNS Nutrilash Lash & Brow Enhancer. This requires patience and fortitude because they are fiddly, litter one's desk and produce results that are subtle at best. I have used FNS Nutrilash for the past month and can now definitively say that it has made my eyebrow a little fuller. It has had no impact on eyelash growth whatsoever: neither growing new lashes or making existing ones longer.
The good news is that does no evil. There are no glaucoma drugs, just vitamin Bs and amino acids. The packaging is wasteful, however.
