no improvement for me [SEP] i used this for over a month before posting this review my lashes had no improvement after using this serum i liked that there was a lot of serum in the small bottle other serums i have tried always seems like there is not much serum in the bottle however a lot of serum gets wasted on the wand because the bottle hole does not help to keep any excess inside see my video for better explanation still the bottom line is that this did not work for me
