I'm 71 years old and my brows had thinned over the years. After 2 months of using Nulastin I am blown away by the results. My brows are now totally filled in and look better than they have in decades. I'm still using the first tube of the lash serum and my lashes are longer and thicker than they have ever been. I'm thrilled to have found a product that actually works as advertised!
