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
