I've always had very average lashes, so when I saw this on special at Farmers, it was a no brainer.
Of the lash serums I've tried, this has my preferred applicator. It's like a little liquid eyeliner brush and allows for good control and accuracy on where you place the product (and how much product).
i would say it took about 8 weeks for me to see results and that was less lash fall out and stronger lashes. They also curled more which did help enhance the length slightly.
Definitely my favourite lash serum packaging. And I also like that you only need to use it once a day.
