Review title is Easy to Use! [SEP] As I have gotten older (I'm in my early fifties), I've noticed that my eyelashes have become sparser. This eyelash growth serum is easy to use. It doesn't sting or irritate my sensitive eyes either. I haven't seen much change in the length of my lashes yet, but I think I can see some new growth or density. I will continue using this and update my review if necessary.
