So I was so excited to receive this product and test it out because a few years ago I got fake permanent lashes. I would fill them every 2 months and at one point after removing them completely I realized I literally had a few real lashes left. It took a few years to grow some back and my issue now has been for a fuller look of lashes. This product didn’t do anything to my lashes. I thought they would get longer or fuller but unfortunately it was nothing but a waste of time. I even was very committed in applying the serum twice daily for the 4 week time frame. I’m really disappointed and really wish that this serum would actually work. L’Oréal usually has great products but this was not quite.
