My lashes are not the first thing anyone would notice on my face, however when I have used this primer before a night out, I had been asked if I had falsies on or if I took Latisse. I give all the credit to this lash primer. You put it on before your mascara. I use a couple different mascaras and found it generally works with most mascaras. I do like how it looks under Clinique's High Impact mascara. The primer is usually around $14.00 at department stores or beauty stores.
