As a base coat, it smooths ridges and creates a really nice canvas for colour application. Even after it's dried, there's a slight tackiness, helping the polish adhere and apply with minimal streaks.
The shine when used as a top coat is nice, but it can take nearly an hour to dry completely. I can't keep my hands still for that long! I always end up with a smudge on at least one finger. It seals the colour decently, but chips a little faster than some other top coats I have tried. Although, I think 'chippage' can also be related to the brand/finish of the nail colour itself.
To conclude, I genuinely like this product! My nails have never felt better!
Sidenote: Please leave me a comment if you've ever had to go to the washroom whilst waiting for your nails to dry. Trying to undo buttons on your pants with a fresh mani is an exhausting battle. The struggle is real, people!
