This lash primer is awesome! Since I began using it several years ago, I noticed I lose very few lashes anymore and my eyes pop that much more with mascara. I even recommended it to others and they now use it regularly as well. I tried a drug store version, but it irritated my eyes and didn\’t work as well. I\’ve tried a few other designers but always come back to this one for the price point, effectiveness, and attention to people with sensitive skin/eyes (allergies). I already have long lashes, but this helps them be slightly more thick and also seems to help the overall wear of my mascara and health of my eyelashes. Highly recommend as a beginner or forever lash primer!
