• Analyst Opinion at Fact.MR
  • Shambhu Nath Jha, Senior Analyst at Fact.MR, states, “CGM underpatches look like simple adhesive accessories, but users treat them as wearability products. If a sensor irritates skin or lifts early, the device experience suffers. Suppliers that solve comfort, compatibility and removal will be better positioned than brands selling generic tape.”
• Strategic Implications
  • Underpatch brands should design by device shape instead of selling one generic adhesive format.
  • Diabetes clinics should guide users toward skin-safe options when irritation affects sensor wear.
  • DTC brands should build refill programs around sensor replacement cycles and activity needs.
  • Pharmacies should separate CGM underpatches from ordinary bandages and athletic tapes.

CGM underpatches sit below the wider diabetes management ecosystem because they support continuous glucose monitoring use but are not software or the sensor itself. The category differs from overpatch tapes because an underpatch is used as a skin-facing barrier or support layer under the device adhesive.

The American Diabetes Association’s 2026 Standards release recommends continuous glucose monitoring at diabetes onset and anytime thereafter for people who can benefit from its use in diabetes management. [1] This supports the market boundary because CGM underpatches are accessory products tied to continuous sensor wear, not standalone glucose monitoring devices.

The United States is projected to record 12.9% CAGR through 2036 as CGM adoption and DTC patch brands create recurring underpatch purchases. Germany is expected to post 12.2% CAGR through 2036 as diabetes device users seek skin-safe wearable accessories. Japan is likely to record 11.8% CAGR as compact CGM use supports discreet adhesive formats. China is forecast to advance at 11.4% CAGR as wearable glucose monitoring moves into urban wellness and diabetes care channels. India is set to record 10.8% CAGR as CGM access expands through private clinics and online channels.

How does the CGM underpatch market break down by segment?

Hypoallergenic tapes lead at 35.0%; Dexcom-compatible underpatches lead at 38.0%.

Which adhesive material dominates?

Hypoallergenic tapes hold 35.0% share in 2026.

Hypoallergenic tapes are expected to hold 35.0% share in 2026 because sensitive skin is a core reason users look for an underpatch. These formats help users reduce discomfort from repeated sensor adhesive contact. Hydrocolloid underpatches are important where users want stronger barrier behavior. Silicone adhesive supports gentler removal. Acrylic medical adhesive supports longer hold. Transparent PU film is useful where users want a thin and discreet layer. The segment connects with wearable adhesives because CGM wear needs skin-safe bonding over several days.

Which device compatibility dominates?

Dexcom-compatible underpatches account for 38% share in 2026.

Dexcom-compatible underpatches lead because device-specific adhesive products are heavily sold through DTC and Amazon channels. The segment is projected to capture 38.0% share in 2026 as Dexcom G6, G7 and Stelo users look for better retention and skin protection. Abbott FreeStyle Libre-compatible formats follow because Libre has strong global sensor use. Medtronic Guardian formats serve insulin-dependent users. Universal CGM cutouts suit consumers who want one patch family for several devices. The FDA cleared Dexcom Stelo as the first over-the-counter continuous glucose monitor in 2024, widening the consumer-facing CGM pathway. [2]

Which wear need dominates?

Irritation-barrier support holds 41.0% share in 2026.

Irritation-barrier support leads because users often search for underpatches after experiencing redness, itching or adhesive discomfort. The wear-need segment is likely to account for 41.0% share in 2026 as repeated CGM wear makes skin tolerance a recurring issue. Sweat and water protection adds demand among active users. Sensor retention matters when premature lifting causes device loss. Overpatch layering is used when users combine an underpatch with a top patch. ExpressionMed states that its Dexcom G7 and Stelo UnderPatch is designed to protect skin from reactions to harsh adhesives by serving as a barrier between skin and the device. [3]

Which channel dominates?

DTC brand sites lead with 36% share in 2026.

DTC brand sites lead because users search by device, color, material and skin need. The channel is expected to hold 36.0% share in 2026 as brands sell refill packs, bundles and device-specific shapes directly. Amazon supports fast discovery and reviews. Pharmacies and medical distributors support clinical trust. Diabetes educators and clinics influence first-time product choice. Subscription refills grow where users align patch delivery with sensor replacement cycles. Dexcom’s 2025 adhesion guidance notes that clean, dry skin and moisture control help sensors stay secure during wear. [4]

What is accelerating CGM underpatch adoption, and what is holding it back?

Rising CGM wear and skin irritation control are driving adoption, while incorrect application risk and skin reaction variability restrain it.

Drivers Impact Analysis

• CGM wear growth
  • CGM wear is the strongest demand base because every sensor cycle creates an adhesive-use moment. Users who face lifting, sweating or skin irritation often add an underpatch or barrier layer. This makes the category recurring. It is tied to the sensor installed base but stays commercially separate from the CGM device.
• Skin irritation control
  • Skin irritation control is central because underpatches are often bought after a poor sensor-wear experience. Users need materials that create a barrier without interfering with device insertion or sensor function. This driver favors hydrocolloid, silicone and hypoallergenic tape formats. It also supports brands that explain application steps clearly.
• DTC and Amazon discovery
  • DTC and Amazon channels are important because users search by device name and skin issue. A Dexcom G7 user may want a different cutout than a Libre user. Reviews help shoppers compare adhesive strength and removal comfort. This channel structure favors brands with strong device-specific assortments.
• Sweat and water resistance
  • Sweat and water resistance matter because CGMs are worn during exercise, showering and daily movement. Patches that lift early can create sensor-loss anxiety. Users want products that hold without feeling harsh on skin. Skin Grip’s 2025 adhesive guidance describes sweat, showers, workouts and swimming as common reasons diabetes-device adhesives can peel early. [5]
• Pediatric and teen use
  • Pediatric and teen CGM users create demand for comfortable and expressive patches. Parents often look for designs that reduce device anxiety and help sensors stay on during school, sports and sleep. This creates opportunity for patterns, gentle materials and smaller sizes. The driver will grow as younger users adopt CGM more widely.

Opportunity Impact Analysis

• Sensitive-skin underlayers
  • Sensitive-skin underlayers create opportunity because repeated CGM use can make even small irritation a reason for product switching. Hydrocolloid and silicone materials can support users who cannot tolerate ordinary sensor adhesive. Brands that explain insertion-through-patch use and removal steps can improve trust. The opportunity is strongest in DTC and diabetes educator channels.
• Device-specific bundles
  • Device-specific bundles reduce confusion for users. A bundle can include an underpatch, an overpatch and skin-prep instructions for a defined CGM model. This helps users avoid wrong-size purchases. Underpatch suppliers can create clearer starter packs for Dexcom, Libre, Stelo and Lingo users.
• Subscription refills
  • Subscription refills can align patch delivery with sensor replacement cycles. Users who wear CGMs continuously need predictable stock. Refill models also allow brands to offer seasonal materials, color packs and activity-specific adhesive strength. This opportunity connects with implantable glucose monitors because continuous monitoring behavior creates recurring accessory use.
• Clinic-guided recommendations
  • Clinic-guided recommendations can reduce trial-and-error for new CGM users. Diabetes educators can suggest underpatch options when skin sensitivity or adhesion failure appears early. This creates trust and can reduce sensor discontinuation caused by comfort issues. The opportunity connects with insulin pumps because pump and CGM users often buy adhesive accessories across device types.

Restraints Impact Analysis

• Incorrect application risk
  • Incorrect application is the main restraint because the patch must not block the sensor pathway or interfere with insertion. Users may apply the product too late, cover the wrong area or choose the wrong cutout. This can reduce confidence in the product. Clear instructions and device-specific designs are needed to protect adoption.
• Skin reaction variability
  • Skin reaction varies by person, adhesive chemistry and wear time. A material that works for one user may irritate another. This creates returns and negative reviews. Underpatch brands need material choices and skin-prep guidance. The restraint is strongest among users who already have adhesive sensitivity.
• Compatibility confusion
  • Compatibility confusion can slow purchase because CGM models differ in size and shape. Users may buy a Dexcom G6 patch for a G7 sensor or confuse Libre versions. This issue is common on marketplaces with many listings. Strong product naming and clear diagrams can reduce confusion.
• Generic tape price pressure
  • Generic tapes and low-cost patches create price pressure. Some users prefer cheaper athletic tape or medical tape if they only need extra hold. Dedicated underpatch brands must prove better comfort, shape fit and sensor-specific design. ExpressionMed’s 2025 wear-time guidance says CGM or pump tape performance is shaped by material quality, skin quality and external environment. [6]
