This is a cult-status, holy grail top coat for many, and it's easy to see why once you've experienced it: it penetrates all the way down through layers to the nail bed, bonding all and everything together. The texture is a bit on the thicker side and it does take some persistence to remove it, but you might find that totally worth it for the effortless nail polish longevity it provides.
New and in stores now, this quick-dry top coat is infused with hemp seed oil, full of essential fatty acids and vitamin E, and UV inhibitors. It will extend wear, prevent chipping, and protect the color. It's also vegan, 10-free and gluten-free.
