I have long lashes and i'm always trying to take care of them because sometimes when you use the eyelash curler you might cut you them. I've been using this serum for a month every night before to go to sleep and I had the best results. My lashes are longer and stronger, and the best thing is that you can use it also before you put the mascara on your lashes. 100% recomended if you are looking to have long and strong lashes. One of my favourite products.
