Visit our short Sensor Application & Adhesion Guide English PDF (2.2 MB) | Spanish PDF (3.0 MB) or view the video below for guidance on how best to apply the sensor so it stays in place. Sensors stick better when you wash, clean, and dry your skin before application.
You can find additional resources, such as helpful tips and tutorial videos for sensor application and care, on the FreeStyle Libre 3 system support page.
If your sensor falls off before 15 days of wear please complete the online sensor support request form or contact our Customer Care Team at 855-632-8658.
Applying and removing your sensor
Tips: Where to place the sensor
• Select a flat area on the back of your upper arm (no bending or folding).
• Choose a place that is at least 1 inch (2.5 cm) away from an insulin injection site.
• To avoid irritation, we recommend moving your next sensor to the other arm.
How to prep your skin
• Wash: Only use non-moisturizing, fragrance-free soap to wash the area where you’ll apply the sensor.
• Clean: Use an alcohol wipe to remove any oily residue
• Dry: Skin must be completely dry. Take care after showering, swimming or working out.
Top Prep Tips for Extra stickiness
• Moisture: Application area needs to be completely dry
• Hair: Consider shaving the application area
• Oily Residue: Application area should be free of soap, lotion, shampoo, or conditioner
