This seems like a decent lash primer. I was using the one from Dior, but I wanted to try this one. It's a bit smaller, but it seems to do the job. Time will tell how long it will last. The Dior one seemed to last forever, but I thought it was a bit expensive.
This is one of my go to products. It helps condition your lashes and makes them look long after applying your mascara. I recommend this product highly. I will definitely buy again
I have been using Estee Lauder's Lash Primer Plus for many years. It is and does everything advertised. You are adding length before you even apply mascara, so your lashes will be much longer with this product. I love it!
