Introducing the Dexcom G7 Underpatch with External Grip: Comfort Meets Confidence
Living with Type 1 Diabetes (T1D) means constant attention to detail—from monitoring blood glucose to managing insulin dosing. A key tool in that journey is the Dexcom G7 continuous glucose monitor (CGM). But even this best-in-class device can sometimes cause skin irritation especially on sensitive skin.
That’s why we created the Dexcom G7 Underpatch with External Grip—a high-performance, easy-to-use underlay patch designed to pair seamlessly with the Dexcom G7 applicator and provide a new level of skin-friendly, secure wear.
1. The Simple Power of a Dexcom Underpatch
Imagine having an extra layer of defense between your skin and the CGM adhesive—a barrier film for Dexcom G7 that protects sensitive skin without compromising sensor accuracy or comfort.
- Barrier Protection: Applies beneath the CGM adhesive to prevent skin irritation without affecting sensor readings.
- Secure Adhesion: Reduces the risk of the dexcom G7 lifting during exercise, baths, or swimming.
- Hypoallergenic: Latex‑free and free from harsh chemicals—crafted for those seeking the best Dexcom G7 patches for sensitive skin.
2. Hypoallergenic and Gentle: Made for Delicate Skin
Whether you're embracing Dexcom for the first time or have been wearing CGMs for years, skin reactions are common: redness, itching, contact dermatitis. Our underpatch is engineered with a soft, breathable, hypoallergenic material that lets skin breathe while providing cushioning.
Key features include:
- Gentle on Skin: Crafted to reduce rash, redness, and itch, ideal for users with sensitive skin or frequent patch changes.
- Breathable Design: The non-fraying woven fabric allows airflow to prevent sweating and moisture buildup.
- Flexible & Thin: Easily conforms to curves like the upper arm, abdomen, or love handles.
This design ensures a comfortable, longer-term wear experience.
3. Reinforced Stability via External Grip
Activities like sports, showers, and travel can challenge adhesive strength. That’s why we integrated an external grip—a supportive outer ring that clings to the adhesive of the CGM.
- Adhesive Lock-In: Extra grip helps keep the Dexcom sensor adhered to the G7 under patch.
- Water & Sweat Resistant: Holds well even during workouts, humidity, heat, and pool days.
- Secure but Gentle: Our flexible 8-way stretch material allows the patch to move and prevent the adhesive from pulling the skin.
A sturdier fit means fewer sensor disruptions and more reliable glucose data.
4. Easy, Accurate Application—No Training Needed
A revolution in ease-of-use: each underpatch is exactly aligned to match the Dexcom G7 applicator, minimizing placement mistakes.
Here’s How Simple It Is:
- Same Dimensions: Sized exactly like the Dexcom G7's applicator.
- Align Straight Edges: Line up the straight edge of the underpatch with the straight edge of the Dexcom applicator base.
- Needle-Ready Design: Once aligned, insert the sensor per normal—its needle passes through the center hole in the underpatch effortlessly.
- Effortless, No-Guesswork: No trimming, no measuring—just align, click applicator down, and you’re set in seconds.
This foolproof process ensures confident placement—even for those applying on others (like children or partners).

6. Real Stories, Real Impact
Here are authentic experiences from real users that highlight why this solution is making waves:
- Andi, T1D Athlete Mom: “My 12-year-old swims daily and was always losing sensors. Glucomart's G7 underpatch with the external grip held for the full sensor length."
- Megan, Teacher & T1D Patient: “As someone with easily irritated skin, I was ready to stop using CGMs. This underpatch was a game-changer—no red marks, no itching, and for the first time I forgot I was even wearing a sensor.”
- Maria, Mom of T1D toddler: “My daughter looked like her skin was burned from an allergy to the Dexcom G7 adhesive. We tried numerous underpatches with no luck, they either came off or caused the same reaction. We got Glucomart's Dexcom G7 Underpatch and it saved my daughter's skin.”
7. Tips for Optimal Use
To get the best performance from your Dexcom underpatch, follow these friendly guidelines:
- Prep Clean Dry Skin: Use a non-moisturizing soap then alcohol swab. Allow the alcohol to dry completely.
- Let Skin Dry: Fully dry your skin (at least 30 sec) before applying the underpatch.
- Align Precisely: Match the straight edges, apply moderate pressure, then apply the sensor.
- Seal the Grip Ring: Press firmly around the external grip rim after placement.
- Add Overpatch (optional): Center the Glucomart overpatch for an added adhesive protection.
8. A Breathable, Comfortable Wear Experience
We designed this underpatch to feel like clothing—not medical gear:
- Thin & Featherweight (~0.2 mm): Often forgotten you’re wearing it.
- Breathable Structure: Allows skin to breathe, minimizes sweat buildup.
- Latex-Free, Lab-test dye: Created for sensitive skin types. All dye used in our patches has been tested for toxic chemicals and exceeds safety standards.
- Cling Without Stickiness: Gentle adhesives reduce the “tug” sensation.
9. Comparisons: Why We Stand Out
All current underpatches on the market either use a non-woven material which increases the risk of sweat build up and irritation or they use fraying woven fabric, which can breath, but quickly unravels at the edges making it quickly unstable.
10. Frequently Asked Questions
Q: Can I swim or shower with it?
A: Absolutely. The adhesive is made to work in the water and the external grip keeps the Dexcom G7 firmly attached to the underpatch.
Q: How long does it last?
A: Wear time matches your CGM sensor cycle—up to 10 days—with no need to change mid-cycle.
Q: Can I apply it myself?
A: Yes! The easy alignment and applicator-friendly design means quick self-application.
