The top coat dries very quickly! It does cause a bit of shrinkage on the polish underneath, so you might see a bit of the polish pull back once the top coat fully dries, and you might see a "seam" where the top coat ends (on the sides).
Side note: I ordered this top coat with a previous order and the bottle I received came without a brush. I emailed customer support and received a very kind response in return. They took great care of me and resolved the issue quickly despite it not being an error on their part. I really appreciate the care that went into their response and the prompt action to resolve the problem. I have shopped here in the past and will continue doing so for my nail needs! :)
