Using Dexcom ONE in the Long Run

How can I avoid irritated or sensitive skin caused by the sensor adhesive?

Last Updated · September 28, 2021

These considerations, skin barriers, and professional tips may help. Remember what works best for one person may not work best for everyone. You and your HCP may need to try several different products or methods to figure out whether these options work for you.

General consideration*

  • Clean skin with oil-free, antimicrobial soap and dry thoroughly1,2
  • Gentle exfoliation recommended for oily skin2
  • Trim hair with dry razor if needed3
  • Do not use any lotion or oil containing moisturizer where you insert the sensor
  • Do not insert sensor immediately after a shower/bath or in a steamy bathroom—minimize humidity with hairdryer or application in a dry environment2
  • Solid or spray antiperspirant (unscented) may help with skin prone to sweating. Create an empty oval on the skin with the antiperspirant, wait 10–15 min. Insert sensor on clean skin in center of oval.1,2

Barrier Films*

  • Barrier films may help prevent mild skin irritation from adhesives4
  • Create an empty oval on the skin with the barrier film and insert sensor on clean skin in center of oval
  • Let barrier film dry completely before placing sensor1,4
  • May apply 1 layer or a second after first layer has dried
  • Barrier films may be an irritant itself and may not prevent allergens from skin penetration

Barrier Patches and Bandages*†

  • Use barrier patches and bandages only if barrier film did not work for you
  • Dexcom has not tested the use of barrier patches and bandages. Talk to your HCP about the use of barrier patches and bandages.
  • When used as a barrier, patches/bandages must be placed underneath the sensor adhesive patch1,5,6
  • Place on skin before sensor adhesive • Cut an empty oval in the patch/bandage and insert sensor on clean skin in center of oval
