Direct answer: Store a microneedling pen powered off, dry, protected from impact and contamination, and separated from used cartridges. Storage should preserve the device's external condition without implying that the device or cartridge is sterile.
Before storage
- Remove and discard the used single-use cartridge.
- Confirm the device exterior and charging port are dry and visibly undamaged.
- Do not store the device while connected to charging unless the model documentation specifically requires it.
- Keep the cable loosely arranged and free from sharp bends, crushing, or tension at the connector.
Choose a stable storage environment
Use a clean, dry location away from direct heat, strong sunlight, moisture, children, pets, and objects that can press on the controls or connector. Keep unused cartridges in their original sealed packaging and verify compatibility before use.
Inspect before the next use
Check for housing damage, port looseness, discoloration, unusual odor, swelling, or evidence of moisture. Do not charge or operate a device with concerning damage; collect evidence and contact support.
Open the Device Care and Troubleshooting Hub for inspection, charging, and escalation guidance.
Check cartridge compatibility by model before opening a replacement.
This article covers product storage and ownership boundaries. Storage does not sterilize a cartridge or make a damaged device safe to use.
