Keeping your manicure and pedicure looking fresh for as long as possible can be a challenge. Everyday activities and daily chores can affect the shine of the polish and potentially cause chips or scratches. When properly applied, a manicure should last one to two weeks and a pedicure should last two to four weeks. To extend the life of your manicured nails, add a layer of topcoat every few days. Pedicure Tip: To disguise inevitable chips and extend the life of your pedicure, use lighter color polishes instead of bright ones.
