Did not see any difference with the new and improved serum to my results with the original lash serum. The original worked well for me and both serums showed lash growth and good results close to the 60 days of use. Considering the amount of ingredients in the new formula, 31 ingredients (some not so good) compared to only 7 (all good) in the original, wow! I will be sticking to the original lash serum.
