A drawer or cupboard is ideal.- Keep Upright: Store the bottle in an upright position to prevent leakage and maintain the quality of the sprayer mechanism.- Secure Cap: Always replace the cap tightly after use to prevent evaporation and exposure to air, which can alter the scent over time.- Avoid Shaking: Excessive shaking is generally not recommended as it can introduce air into the liquid and potentially degrade the fragrance molecules.Compatibility: Marc Jacobs Daisy Eau So Intense is designed for general adult use.

Always perform a patch test on a small area of skin if you have known sensitivities to fragrances.
