I bought this product from www.nextlevel-lash.com. I used the coupon AMAZON and saved 25% - I dont know if its still valid but worth a try.

The serum is all natural which is why I chose that one over other brands. I didnt see any results for like 3 weeks but then after that my lashes got really long and thick. When I apply mascara on top of them, it honestly looks like I am wearing fake lashes. You have incporporate it into your daily routine - consistency is key!
