This is my new favourite thing! I have about a million nail polishes and love changing the colour of my nails all the time but I always hated waiting for them to dry. I'd always end up smudging them even after it seemed like I'd waited for ages for them to dry!
This stuff is amazing if you are in a rush painting your nails. It says it dries your nails in 30 seconds and it really does. I wasn't expecting it to be as good as it is, I thought it would still take a while to dry but it does exactly what it says on the tin. Not only does it dry your nails super fast but it makes them sooo shiny! I've never used a topcoat that makes my nails look so shiny I'm really impressed with it. I bought mine from boots for £5.99 which i think is an okay price as it's a really good product.
Have you tried Sally Hansen Insta-Dri?
