Operating Instructions
- Cleanse Skin: Thoroughly cleanse the treatment area and apply a suitable serum or glide product.
- Adjust Needle Depth: Rotate the adjustment ring on your Dr. Pen device to select the desired needle depth. The MPK 16-Pin cartridges have a fixed needle length of 0.26mm, but the device allows for depth adjustment based on your treatment needs.
- Power On: Turn on your Dr. Pen device. Select the appropriate speed setting.
- Begin Treatment: Gently glide the pen over the skin in small sections, using light pressure. Avoid dragging or applying excessive force.
- Post-Treatment: After completing the treatment, turn off the device.
Maintenance
- Single-Use Only: MPK Microneedling Pen Cartridges are designed for single-use only. Reusing cartridges can lead to contamination and compromise treatment effectiveness.
- Disposal: After each use, safely detach the used cartridge from the device and dispose of it in a sharps container or according to local regulations for medical waste.
- Device Cleaning: After removing the cartridge, clean the Dr. Pen device according to its specific instruction manual.
- Storage: Store unused cartridges in their original, sealed packaging in a cool, dry place, away from direct sunlight and moisture. Keep out of reach of children.
Troubleshooting
Common Issues:
- Cartridge Not Attaching Securely: Ensure the cartridge is correctly aligned with the 3-slot design on the Dr. Pen device. Twist firmly until it clicks into place. If it still doesn't fit, verify that you have the correct cartridge type for your specific Dr. Pen model (M8 or M7S).
- Excessive Discomfort or Pain: While some sensation is normal, excessive pain may indicate incorrect needle depth or technique. Ensure your skin is properly numbed if necessary, and adjust the needle depth on your device to a shallower setting. Always use a gentle gliding motion.
- Needles Not Extending: Check if the cartridge is fully seated and locked onto the device. Ensure the device is powered on and the needle depth is adjusted correctly. If the issue persists, the cartridge may be faulty and should be replaced.
- Device Malfunction: If the Dr. Pen device itself is not functioning correctly, refer to the device's own instruction manual for troubleshooting or contact the device manufacturer's support.
