I've been using this solution for over a year. My ophthalmologist was shocked at how long my eyelashes had grown, so I encouraged her to try the product. It also has a long shelf life, with an estimated reorder period of 6 months!

This stuff amped up my lash routine by 100. I've been using Nulastin for both lash and brows, and it works, definitely, but it's spendy. I felt my lashes were getting longer but not thicker and were dry and brittle feeling.
