I have been trying to find a nail treatment base coat to help my nails grow longer. It is a nail fortifier but I used it as a base coat and a top coat. I use it for a base coat to help harden my nails to grow longer and use it as a top coat because this products helps whatever nail color I apply with it, to last longer. It's also very quick drying. Compared to a few nail hardener and fortifier that I had tried, this is the best because it doesn't chip. It will last up to at least a week without chipping, by using it alone. It has helped me to getting the long nails that I've always dreamed of. Now I don't think I can go without this product. Just bought it a month ago and it's already half way through.
