This Eau de Parfum is designed for immediate use directly from the spray bottle, requiring no complex setup.To ensure the longevity and preserve the quality of the fragrance, proper storage is essential. Always store the bottle in a cool, dry place, away from direct sunlight, extreme heat, or cold temperatures. Exposure to direct light and fluctuating temperatures can degrade the delicate scent molecules over time. Ensure the cap is securely fastened after each use to prevent evaporation and oxidation, which can alter the fragrance's profile.Regarding compatibility, K Intense is generally suitable for all adult skin types. However, for individuals with particularly sensitive skin, it is always recommended to perform a patch test on a small, inconspicuous area of skin (e.g., inner forearm) before full application. Avoid spraying the fragrance directly onto irritated, broken, or freshly shaven skin to prevent potential discomfort or irritation.
