Review (5/5): It actually works.
I am impressed. My nails are damaged an weak from liquid gel manicures.
I apply the product over my nails, as described and it actually seems to provide a protective barrier on my nails, while the damage portion grows out. The damaged portion is brittle, so it broke off at the tip, which I clip and file away.
My nails are growing faster than expected, and the new growth feels stronger and looks healthier. I can tell when my nails are bare, to apply new coats.
My only caution, it does peel after a few days if you don't add another coat. If this happens, use nail polish remover to take it off. It will peel a layer off of your nails if you try to pull it off.
