A manicure system with the right tools (and using them correctly) is the number one step!
If you've washed your hands or gotten them wet, wait 2 hours before painting them to prevent them from chipping.
Take your time! Let each coat of polish dry a bit before applying the next coat.
Right before you start polishing your nails, dip them in the polish remover pot one more time!
To keep your nails flawless, apply the top coat daily and cuticle serum 2-3 times per day!
