Setup: Using your Rouge Dior Lipstick is straightforward. Simply remove the cap from the magnetic case to reveal the lipstick bullet. There is no complex setup required. Compatibility: This lipstick is designed to be compatible with other DIOR makeup products, particularly DIOR lip liners for precise contouring and extended wear. It can be worn alone for a subtle look or as part of a full makeup routine. Care: To maintain the quality and integrity of your Rouge Dior Lipstick, store it in a cool, dry place away from direct sunlight and extreme temperatures. Always recap the magnetic case securely after each use to prevent drying and damage to the bullet. Avoid dropping the lipstick, as this can affect the bullet's shape and the magnetic mechanism of the case. If the bullet appears to have a slight film or dryness after prolonged non-use, gently blot the surface with a clean tissue before applying.
