FreeStyle Libre 2 and FreeStyle Libre 3 sensors are applied in the same way.

The Sensor is applied on the back of the upper arm with a disposable device called an applicator. When the Sensor is applied, a small (5mm) sterile filament is inserted just under the skin, and held in place with a small adhesive pad. In a study conducted by Abbott Diabetes Care, most users agreed that inserting the Sensor was no more painful than a typical finger prick glucose test*.

*Data on file. In a study conducted by Abbott Diabetes Care, 93.4% of patients surveyed (n=30) did not feel discomfort under the skin while wearing the Sensor.
