Wearing a FreeStyle Libre sensor allows you to monitor your glucose without constant pricking, but like any medical device, it requires certain care. If you want to know how to properly and effectively protect your FreeStyle Libre sensor, keep reading. Here you'll find all the useful and up-to-date information you need to achieve this goal.
In this article, we explain the best strategies and products to keep your sensor safe, comfortable, and functioning properly throughout its lifespan.
What is the FreeStyle Libre sensor and what is it used for?
The FreeStyle Libre sensor is a continuous glucose monitoring (CGM) device that is worn on the back of the upper arm. This device continuously measures glucose levels in the interstitial fluid and transmits the data to your smartphone via the FreeStyle LibreLink app. The sensor lasts up to 14 or 15 days, depending on the model, and allows real-time monitoring of glucose levels.
This is a very useful tool for people with type 1 and type 2 diabetes, as it eliminates the need for frequent self-prick checks. It also offers smart alarms, automatic readings, and is compatible with apps like LibreView and LibreLinkUp. This technology has transformed the lives of many people with diabetes, allowing them to live with greater freedom and security.
Why you should protect your FreeStyle sensor
Although the FreeStyle Libre sensor is designed to be durable, many everyday factors can put it at risk:
-
Premature shedding due to sweat, friction or sudden movements.
-
Loss of adhesion after showers, swimming or sports activities.
-
Accidental bumps while sleeping or getting dressed.
-
Hot or humid environments that affect the adhesive.
-
Tight clothing or abrasive materials that cause friction.

Tips for protecting your FreeStyle Libre sensor
If you want to know how to properly protect your FreeStyle Libre sensor, the key is to use additional accessories that improve its grip and reduce the risk of damage or falls. Below, we share some tips based on user experience and official Abbott recommendations:
Prepare the skin well before applying it
Proper skin preparation ensures better adhesion of the adhesive and reduces the risk of detachment. Before placing the sensor on your arm, it is recommended to:
-
Clean the area well with alcohol and let it dry completely.
-
Avoid creams, lotions or oils that hinder adhesion.
-
Shave the area if there is abundant hair that makes it difficult to hold.
Avoid areas of high friction
Although the sensor is designed to go on the back of your arm, make sure to place it in an area where it won't rub against seams in clothing or backpack straps. This will prevent accidental detachment.
Use protective patches
One of the best ways to protect your FreeStyle Libre sensor is to use hypoallergenic adhesive patches . These patches are placed over the sensor and help:
-
Increase adhesion.
-
They protect against sweat or water.
-
Avoid accidental snagging on clothing or accessories.
-
Reduce irritation on sensitive skin.
Protect it while sleeping or while playing sports
For those who exercise regularly or move a lot while sleeping, it is recommended:
-
Use support bracelets.
-
Cover the sensor with snug but comfortable clothing.
-
Avoid clothing with abrasive fabrics.
-
Wear compression shirts if you play contact sports.
Wait before wetting it
Although the sensor is water-resistant, it's a good idea to wait at least an hour after applying it before showering or swimming. This gives the adhesive time to set properly. Don't forget to dry it with a soft towel after contact with water.
Be careful when changing clothes
When changing, be careful not to accidentally pull on the sensor. Avoid getting the sensor caught on sleeves, bras, straps, or backpacks.
