Freestyle Libre 2 & Lingo : Hypoallergenic Allergy Underlay Skin Barrier Adhesive Patches

FreeStyle Libre 2 & Lingo Hypoallergenic Underlay Skin Barrier Patch

Looking for an alternative adhesive barrier for your FreeStyle Libre 2 or Lingo sensor? The Freedom Patch Underlay is designed to sit between your skin and the original sensor adhesive, creating a soft, latex-free barrier for users who prefer an additional layer between their skin and CGM adhesive.

Our round FreeStyle Libre 2 & Lingo underlay patches are designed specifically for CGM application, with a center opening that allows proper sensor insertion while providing coverage beneath the original sensor adhesive.

Designed for FreeStyle Libre 2 & Lingo

The Freedom Patch Underlay is specially shaped for FreeStyle Libre 2 and Lingo sensors. Apply the underlay directly to clean, dry skin first, then apply your sensor over the top according to the sensor manufacturer's application instructions.

The center opening is designed to leave the sensor insertion area unobstructed while the surrounding underlay creates a barrier between your skin and the sensor's original adhesive.

Four Latex-Free Adhesive Options

Different skin types can respond differently to adhesives. That's why we offer multiple underlay materials so you can find the option that feels best on your skin.

✅ Waterproof & Flexible Tan Skin Texture – V1
✅ Waterproof & Flexible Tan Skin Texture – V2
✅ Waterproof Micro-Woven Polyester – V1
✅ Waterproof Micro-Woven Cotton – V2

Test Your Underlay Before Sensor Application

Important: We recommend testing your selected underlay patch on your skin before using it underneath a CGM sensor. This allows you to evaluate how your skin responds to the material and adhesive before committing to a full sensor application.

Once you've found the underlay material that works best for you, it can be used as a barrier beneath your FreeStyle Libre 2 or Lingo sensor.

Overpatch Recommended for Added Durability

For the most secure setup, we recommend applying a FreeStyle Libre 2 compatible overpatch over the sensor after application. An overpatch provides additional coverage around the sensor and underlay, helping reinforce the edges and improve overall durability during everyday wear, sleep, exercise and other activities.
