I am 52yrs old. Over the past 5yrs now, my eyelashes have thinned and gotten so short that it literally looked as if i had no lashes left. i even had an area on my left eye where there were no more lashes. I stopped wearing make up except when I put false eyelashes on. I became very self conscious of my appearance due to the way my eyelashes had just about disappeared. I've been using this product for 5 1/2wks now. My eyelashes have tripled in length and are filling out beautifully!!! They are almost where I want them to be!!! I've had no side effects, no irritation which amazed me because I have very bad allergies and my eyes tend to itch and are dry. This product has not irritated my eyes at all!!!! I am so happy and will continue to use it!!! I threw away all my false eyelashes!!!! woohoo!!!!!! Thank you LiLash for such an amazing product, and thank you overstock.com for carrying it!!!! I highly recommend this product to anyone who is either needing their lashes to grow back, or just wanting longer, fuller, darker lashes!!! amazing product!!!!
