After 1 month of use the results are in!  I have definitely seen the change in the length of my lashes.  I am still waiting for fuller lashes.  My lashes were already dark, so I do not anticipate any change there.  Again, optimal results are reached within 8 weeks, so I will keep reporting.

Keeping track of lash length is difficult, so here is my measuring technique.  With the help of photos, I measured the length of my lashes in three places (inner, middle, outer) then divided the measurements by three to get an average.

In four weeks I have seen .40 mm of growth in Right eyelashes and 0.57 mm of growth in Left eyelashes.
