Our own design of a perfect Libre Underlay Plaster that goes on the skin first, under the Freestyle Libre Sensor. The Sensor is then put on top of this Underlay Plaster to prevent allergic reactions to the actual Sensor. It is recommended that you also use a Libre Slimfit Plaster around the side of the Freestyle Libre Sensor after it has been put on top of the Underlay Plaster.
We only use a Hypoallergenic Medical Grade Plaster which lasts very long but please remember to properly clean and prepare the skin before applying any Plasters. Any bacteria on the skin, will be trapped there until the Sensor is removed.
We recommend that you always follow our How to Apply your Sensor and Plaster to Prevent Allergic Reactions and Skin Irritations recommendation which is sent out with all Plaster purchases.
