How to Prevent Skin Irritation When Using CGM Patches
Share
For individuals using CGM patches, skin irritation is a common concern that can lead to discomfort and even premature patch removal. Whether you’re using Freestyle Libre CGM patches, Dexcom CGM patches, or other CGM sensor patches, it's important to prioritize skin health to ensure that the patch stays in place and functions properly. In this blog, we’ll explore practical tips to help you prevent skin irritation when using CGM patches and keep your skin comfortable.
Why Does Skin Irritation Occur with CGM Patches?
Skin irritation can occur for various reasons when wearing a CGM patch. The adhesive used in these patches can cause allergic reactions, friction from movement or clothing, sweat buildup, or prolonged contact with the skin. However, understanding the root causes of irritation can help you take steps to minimize discomfort and ensure optimal performance of your patch.
Tips for Preventing Skin Irritation with CGM Patches
1. Choose a Hypoallergenic CGM Patch
For those with sensitive skin, opting for a hypoallergenic CGM patch can make a significant difference. Many manufacturers offer CGM patches with adhesives specifically designed for sensitive skin, reducing the likelihood of irritation.
- Tip: Look for diabetes sensor patches with gentle adhesive materials that are designed to minimize allergic reactions, such as latex-free and silicone-free adhesives.
2. Clean and Dry Your Skin Before Application
Proper skin preparation is crucial in preventing skin irritation. Applying a CGM patch to skin that is not clean or dry can trap oils, sweat, and dirt, which can lead to adhesive buildup or friction.
- Tip: Use an alcohol wipe or mild cleanser to thoroughly clean the area where you will apply the CGM sensor patch. Allow the skin to dry completely before sticking the patch to ensure proper adhesion and minimize irritation.
3. Use a Skin Barrier Film or Adhesive Pad
Skin barrier films or adhesive pads are a great way to prevent direct contact between your skin and the CGM patch adhesive, which can reduce the chances of irritation. These products create a protective layer over your skin, helping to keep the patch in place without causing discomfort.
- Tip: Apply a skin barrier film before attaching the CGM patch. This helps to protect the skin from direct contact with the adhesive, especially if you have sensitive skin.
4. Avoid Rubbing or Scratching the Patch Area
Rubbing or scratching the area where your CGM patch is applied can irritate the skin and affect the adhesive’s effectiveness. This is especially true when the patch is in the early stages of wear, as the adhesive is still settling in.
- Tip: Try to avoid scratching or rubbing the patch area, even if it feels itchy. If you need to relieve the sensation, use a cool compress to soothe the area without disrupting the patch.
5. Wear the Patch in the Right Location
The location where you place your CGM patch can affect skin irritation. Areas with high friction, such as the waistband or the underarms, can cause the patch to rub against clothing, leading to discomfort.
- Tip: Choose smooth, flat areas of your body for applying the CGM patch, such as your upper arm, thigh, or abdomen. These areas experience less friction and are less likely to cause irritation.
6. Stay Hydrated and Dry
Excessive sweating can contribute to skin irritation under CGM patches, especially in hot or humid conditions. Keeping the skin dry and hydrated can prevent moisture buildup, which can weaken the adhesive and lead to irritation.
- Tip: Drink plenty of water to stay hydrated and try to avoid excessive sweating in the area where your CGM patch is placed. If you exercise or sweat heavily, consider wearing a CGM patch cover to protect the adhesive from moisture.
7. Replace the Patch Regularly
While CGM patches are designed to be worn for extended periods, leaving a patch on too long can lead to skin irritation due to friction or sweat buildup. Replacing the patch when it shows signs of wear can help prevent discomfort and skin damage.
- Tip: Follow the recommended wear time for your CGM sensor patch (usually 7-14 days depending on the brand) and replace the patch as needed. If you notice any signs of irritation or discomfort, it’s time for a new patch.
8. Consider Using CGM Patch Covers
If you find that your CGM patch is irritating your skin due to environmental factors like friction or moisture, using a CGM patch cover can provide extra protection. These covers shield the patch from external elements while also minimizing skin irritation.
- Tip: Invest in a CGM cover patch designed to protect against friction and moisture, especially if you're involved in activities like swimming or exercising. It will provide added comfort and reduce the risk of irritation.
When to Seek Medical Advice
While most skin irritation from CGM patches can be prevented with proper care, there are cases where you may need to seek medical advice. If you experience severe redness, itching, or swelling that doesn’t improve with regular care, it could indicate an allergic reaction or an infection.
- Tip: If irritation persists or worsens, consult with your healthcare provider or a dermatologist for guidance. They may recommend alternative CGM patch options or treatments to help manage the irritation.

Preventing skin irritation when using CGM patches is all about proper preparation, skin care, and using the right products.
