The Duo Day & Night is a targeted nail care routine designed to strengthen and regenerate soft, damaged nails in just seven days. Built around the complementary action of a daytime booster and an intensive night treatment, it supports visible repair through a simple, structured approach.

The routine combines the Keratin Booster, a highly concentrated day treatment, with the S.O.S Mask, an overnight care product that deeply hydrates and protects the nail surface. Together, they form an express cure that helps restore strength, resistance, and comfort to weakened nails.
