The lips are one of the most fragile parts of our face. With cold or excessive heat they can degrade and show a dull or spoiled appearance. Using a lip stick on an ongoing basis will help revitalize and reconstitute your lips. The Roche-Posay Novalip Duo 173 is a lip stick that combines lip care with vibrant, long-lasting color. This stick is ideal for dry, sensitive and dehydrated lips and has a high tolerance. The Roche-Posay Novalip Duo combines care and colour: it enhances the intensity of colour and improves the properties of the skin. Provides an ultra-strong, protective color film that emphasizes the efficiency of skin care, maintaining hydration and color for up to 9 hours.
