The Dior Dolce Vita Eau De Toilette is ready for immediate use. Simply remove the cap and spray. This fragrance is generally compatible with most skin types, but as with any cosmetic product, if you have sensitive skin, it is advisable to perform a patch test on a small, inconspicuous area before full application. To maintain the integrity and longevity of your fragrance, store the bottle in a cool, dark place away from direct sunlight and extreme temperature fluctuations. Heat and light can degrade the fragrance over time, altering its scent and reducing its shelf life. Keep the cap securely closed when not in use to prevent evaporation and contamination. Avoid storing it in bathrooms, where humidity can fluctuate significantly.
