Healing CGM Sites: A Daily Skin Care Challenge for Continuous Glucose Monitor Users

Continuous glucose monitors have changed the way people manage diabetes. They provide real time insights, reduce finger sticks, and help people make better day to day decisions. But for many users, CGMs come with an unexpected and frustrating side effect. Skin damage at the insertion site.

Redness, itchiness, irritation, wounds, and scarring are among the most common complaints from people who use CGMs regularly. Because these devices are worn continuously and replaced frequently, the skin does not always have time to fully recover. Over time, small reactions can turn into ongoing skin problems that affect comfort, confidence, and device adherence.

Understanding why CGM sites become irritated and how to care for the skin properly can make daily CGM use more comfortable and sustainable.

Why CGM Insertion Sites Are a Common Skin Problem

CGMs require repeated insertions into the skin, often in the same general areas of the body. While the technology is advanced, the skin still experiences stress every time a sensor is placed or removed.

Several factors contribute to skin issues at CGM sites.

1. Repeated skin trauma

Each insertion creates a small puncture in the skin. Over time, repeated trauma can weaken the skin barrier and slow healing.

2. Adhesive related irritation

Strong adhesives are necessary to keep CGMs in place. However, prolonged contact with adhesives can cause redness, itching, and irritation, especially on sensitive skin.

3. Moisture and friction

Sweat, movement, and daily activity can create friction under the sensor. This can worsen irritation and prevent the skin from healing properly.

4. Delayed healing

People with diabetes often experience slower skin repair. This means even minor irritation can last longer and become more noticeable.

5. Scar tissue buildup

Using the same insertion areas repeatedly can lead to scarring and thickened skin, making future insertions more uncomfortable and less effective.

Because CGMs are worn daily, these issues can become a cycle that is difficult to break without proper skin care.

Common Skin Reactions at CGM Sites

Many CGM users report similar skin concerns, including:

  • Redness that does not fade after sensor removal

  • Itching or burning sensations

  • Dry or flaky skin

  • Small open wounds or broken skin

  • Tenderness at the insertion site

  • Scarring or dark marks over time

  • Skin that feels thin, fragile, or irritated

While these reactions may start as mild, repeated exposure can worsen them and make continued CGM use uncomfortable.

Why CGM Site Care Needs a Preventive Approach

Most people focus on treating skin irritation only after it appears. But with CGMs, prevention is just as important as healing.

Because sensors are applied regularly, the skin needs support both before and after insertion. Preparing the skin helps reduce irritation, while proper aftercare helps the skin recover fully before the next application.

Without this two step approach, the skin may never fully heal, leading to chronic irritation and scarring.

How Lavior Supports CGM Site Healing and Prevention

Lavior is designed to support compromised skin and slow healing areas, making it well suited for CGM site care. Its gentle, hydrating formula helps protect the skin barrier, calm irritation, and support healing.

Using Lavior before CGM application

Applying Lavior to the intended insertion site before placing a CGM helps prepare the skin. This can:

  • Improve skin hydration

  • Strengthen the skin barrier

  • Reduce friction and irritation

  • Support healthier skin at the insertion point

When the skin is healthy and balanced, it is more resilient during insertion and less likely to become irritated.

Using Lavior after CGM removal

After a sensor is removed, the skin is often stressed, dry, or irritated. Applying Lavior to the site can:

  • Calm redness and itchiness

  • Support healing of small wounds

  • Promote smoother skin recovery

  • Minimize the risk of scarring

This post removal care is essential for allowing the skin to heal properly before the next sensor is placed.

Why Daily Use Matters for CGM Users

Because CGMs are worn continuously, skin care cannot be occasional. CGM users often apply and remove sensors every few days, which means the skin is under constant stress.

Daily use of Lavior supports ongoing skin health by:

  • Maintaining consistent hydration

  • Supporting faster recovery between insertions

  • Reducing cumulative skin damage

  • Helping prevent irritation from becoming chronic

  • Keeping insertion sites healthier over time

This daily routine helps break the cycle of irritation, healing, and reinjury that many CGM users experience.

Reducing Scarring and Long Term Skin Damage

Scarring is a common concern for long term CGM users. When the skin does not heal properly between insertions, scar tissue can build up. This not only affects appearance but can also make future insertions more uncomfortable.

By supporting the skin before and after CGM use, Lavior helps promote healthier healing. Well hydrated, calm skin is less likely to scar and more likely to recover fully.

A Better Experience With Continuous Monitoring

CGMs offer valuable insights and convenience, but skin irritation should not be the cost of using them. With the right skin care routine, CGM users can protect their skin, reduce discomfort, and maintain healthier insertion sites.

Supporting the skin consistently helps make continuous monitoring more comfortable and sustainable for the long term.

The Bottom Line

Skin irritation at CGM insertion sites is one of the most common challenges faced by people who use continuous glucose monitors. Redness, itching, wounds, and scarring can develop when the skin is repeatedly stressed and not given the support it needs to heal.

Using Lavior before and after CGM application helps protect the skin, prevent irritation, and support healing of existing damage. With daily use, Lavior becomes an essential part of CGM site care, helping users maintain healthier skin while continuing to benefit from continuous glucose monitoring.
