The FreeStyle Libre sensor is a game-changer for people with diabetes, allowing for continuous glucose monitoring (CGM) without the hassle of frequent finger pricks. However, like any wearable technology, these sensors can sometimes dislodge or stop functioning before their intended lifespan. To get the most out of your FreeStyle Libre sensor, it’s essential to take care of it properly and adopt some best practices. In this blog, we’ll cover tips and tricks to help you extend the life of your FreeStyle Libre sensor and avoid unnecessary replacements.
1. Prepare the Skin Before Application
Proper skin preparation is key to ensuring that your FreeStyle Libre sensor stays in place and functions correctly. Here’s how to prepare your skin:
- Clean the Area Thoroughly: Wash the application site (usually the back of your upper arm) with soap and water, then dry it completely. Avoid using lotion or oil-based soaps, as these can interfere with adhesion.
- Use Alcohol Wipes: Wipe the area with an alcohol pad to remove any remaining oils or residues. Allow the alcohol to dry completely before applying the sensor.
- Trim Excess Hair: If you have hair at the application site, trim it carefully (don’t shave, as this could cause irritation) to create a smooth surface for the sensor.
2. Apply the Sensor with Care
Applying the FreeStyle Libre sensor correctly can make a big difference in its lifespan:
- Follow the Instructions: Carefully follow the manufacturer’s instructions for applying the sensor. Make sure you position the sensor applicator securely against your skin before pressing down to insert it.
- Press Firmly: After inserting the sensor, press firmly around the edges to ensure it adheres securely to your skin.
- Avoid Stretching the Skin: When applying the sensor, avoid stretching your skin, as this can cause the adhesive to loosen over time.
Now that you know the correct way to apply your FreeStyle Libre sensor, we also offer a guide for using FreeStyle Libre adhesive patches to help ensure secure placement. For more details on FreeStyle Libre patch application and tips, see the full guide here.
3. Protect the Sensor with Adhesive Patches
One of the most common reasons sensors fall off prematurely is poor adhesion. Adding an adhesive patch can provide extra security and keep the sensor in place, even during physical activities or showers. At Type Strong, we offer high-quality adhesive patches designed specifically for CGMs like the FreeStyle Libre. Here’s why using an adhesive patch is a great idea:
- Waterproof and Sweatproof: Adhesive patches are designed to be waterproof and sweatproof, providing extra protection during activities like swimming, running, or working out.
- Long-Lasting Hold: Patches help reinforce the sensor’s adhesive, preventing accidental dislodgement and extending its life.
4. Avoid Impact and Excessive Friction
While the FreeStyle Libre sensor is designed to withstand everyday wear, excessive impact or friction can dislodge or damage it. To prevent this:
- Be Mindful During Exercise: When engaging in activities like contact sports or intense workouts, consider adding an extra layer of protection, such as wearing a sleeve or bandage over the sensor.
- Avoid Tight Clothing: Tight clothing can rub against the sensor, causing friction and loosening the adhesive. Opt for looser clothing around the sensor area when possible.

5. Monitor the Adhesive Regularly
Regularly check the adhesive around the sensor to identify early signs of peeling or lifting. If you notice the edges starting to lift, take action to secure it before it dislodges completely:
- Reinforce the Edges: You can use medical tape or adhesive patches to secure any lifting edges and keep the sensor in place.
- Dry the Sensor Area After Showering: After showering, gently pat the sensor area dry with a towel to prevent the adhesive from weakening.
6. Be Cautious with Water Exposure
While the FreeStyle Libre sensor is water-resistant, prolonged exposure to water can weaken the adhesive over time. To reduce the risk of the sensor falling off:
- Limit Long Soaks: Try to limit the amount of time you spend in water to avoid prolonged submersion.
- Wear a Waterproof Patch: If you plan to swim or take long showers, consider using a waterproof adhesive patch to protect the sensor. Type Strong patches are water resistant.
7. Consider the Timing of Sensor Changes
Choosing the right time to change your sensor can also help extend its life:
- Avoid Changing Before Intense Activities: If you plan to engage in an intense workout or swim soon after applying a new sensor, try to schedule the change for after these activities to give the adhesive time to set.
- Apply the Sensor in a Calm Environment: Avoid applying the sensor in hot or humid conditions, as this can affect how well the adhesive sticks.
Conclusion
By following these simple tips and best practices, you can help extend the life of your FreeStyle Libre sensor, ensuring that it stays in place and functions effectively for its entire intended wear period. Proper skin preparation, additional adhesive support, and careful monitoring can make a world of difference in your sensor’s longevity.
