As a nail art enthusiast, galaxy nails have been my biggest challenge. I've attempted to master the look with techniques that include sponges, topcoats, various glitter polishes, but haven't been able to get just the look just right... until now. I finally realized that the secret, all along, was keeping it simple. The key ingredient to galaxy nails is the flake effect top coat. Layer it on top of a dark blue polish, and voila-- you've got galaxy nails in two simple steps.
