For users who are allergic or sensitive to preservatives, we recommend using our silicone-based personal lubricants, which do not contain any preservatives, to prevent any potential allergic reactions/irritations. For example, our pjur med PREMIUM or pjur med SOFT with jojoba. Alternatively, you can use our preservative-free, water-based personal lubricants such as pjur med SENSITIVE or pjur WOMAN Nude.
