I decided to try this despite already having long lashes, mainly because I was beginning to feel left out from all the people who's lashes now appeared longer than mine from using these sorts of products and falsies. This was recommended by a friend who was onto her 3rd vial, so I knew she meant business. I used the product on my lashes every night and on my brows once in a while to 'fill in the gaps'. It definitely worked. After around two weeks of using this product I decided that my lashes felt too long and stopped using it, passing it onto another family member who needed it.
This product is definitely worth a try, after I stopped using it I did not find that all my lashes fell out as some people complain of in other eyelash serums. Overall a great product, but I probably wouldn't use it again, only because I don't feel the need to.
