This is a nail strengthener designed to treat flaky and pealing nails. It can be used on its own, but applying 2-3 coats on your nails, which is what the brand recommends. However, I mostly use it base coat for my manicures and on its own on my toe nails. It has a beautiful shine to it, with a slight tint, if that can be said. When I applied on its own it my nails are harder to touch than when I use a normal base. Not sure if this will result on my nails being actually stronger, but they are better covered and protected and they don't flake as much.
