Incredible serum and I love that it’s a much more natural alternative to the mainstream prescription & OTC brands, which actually do more harm than good. Liaison uses a healthier route to long/full lashes and it shows, as I have not had a single side effect besides the desired lash effects. Patience is key though, so stick with it. I was not one to feel 100% confident without mascara, but now I am and it’s thanks to this product. Also, you can’t beat the price!
