I was using this lash serum instead of mascara every morning for over a month, as I’m staying at home now and don’t really do any makeup. It just felt nice to brush my lashes with this light weight serum and I kinda made it part of my every day skin care routine.I did not notice any difference in my lash till the day I did put my regular mascara on. My lashes did look longer and thicker and looked amazing! Happy with the product, also great value.
