Generally, routine servicing is not required unless there is an obvious issue with your CryoPen device. The CryoPen is designed to be low-maintenance, and with proper care, it can last for years. The manufacturer provides a five-year warranty, underlining the device's durability.
While there are minimal issues that may arrise with the CryoPen, it's advisable to clean the threads of the device periodically. Additionally, reapplying a coating of silicone lubricant to the threads can facilitate the piercing of cartridges, ensuring smooth operation. Keep in mind that the tips are self-cleaning during device use. However, if the device is dropped, the tips may become damaged, and it's recommended to always keep the cap screwed on between treatments to prevent any unintended damage. If a tip becomes damaged, a new one may need to be purchased.
