This product is amazing, it is seriously worth every penny! I used to wait an hour so that my nails were fully dry. Now I wait 10 minutes and the nail polish is completely dry, I can wash my hands and have zero smudges. I love this top coat, I cannot say enough good things about it. Apply while nail polish is still wet, it will take out any air bubbles/impurities. Do yourself a favor and save a lot of time with this top coat!
