How to Prep Your Skin for Patches: The Right Way to Make Them Last

Living with diabetes often means managing the little things that make a big difference, like keeping your CGM patch firmly in place. Whether you’re using a Dexcom, Medtronic or a Freestyle Libre CGM—proper skin prep can extend the life of your adhesive patch and help you feel more confident and worry-free in your day-to-day routine.

Below, we’ll walk you through the why and how of prepping your skin the right way to make your CGM patches stick longer and stay secure.

Why Skin Prep Matters

Before applying any CGM patch, taking time to prep your skin isn't just a nice-to-have—it’s essential. Here's why:

1. Sweat, oils, and lotion can prevent patches from sticking properly
2. Improper placement can lead to patch lifting, especially during activity or in humid climates
3. Skin irritation can increase if you skip prep or use the wrong products

By understanding how skin prep affects wear time, you'll be one step ahead in making your sensor more reliable—and your life a little easier.

5 Steps for Better Adhesion

If your Freestyle Libre, Medtronic or Dexcom patches aren’t lasting the full wear time, don’t worry—this simple routine can make a big difference. Here’s how to prep your skin for success:

1. Choose the Right Site

1. Pick a flat, low-movement area like the back of your arm or abdomen
2. Avoid areas with body hair, scars, or where skin folds

2. Clean the Skin Thoroughly

1. Use a gentle cleanser or alcohol wipe to remove oils and residue
2. Let your skin fully dry before moving to the next step

3. Use a Barrier Wipe or Adhesion Promoter

1. Products like Skin Tac or IV Prep can help patches stick better, especially in hot or active conditions
2. Apply around the perimeter of the site, not directly under the sensor

4. Avoid Lotions or Oils Before Application

1. Even "light" lotions leave behind residue that affects stickiness
2. Keep the area clean and dry for the best hold

5. Let It Set Before You Sweat

1. After applying your CGM patch, wait 30 to 60 minutes before swimming or working out
2. This allows the adhesive time to fully bond with your skin

Prep Products That Help

Sometimes, it’s not about what you’re doing wrong—it’s about using better tools. Here are a few skin prep products that can support longer wear and more reliable adhesion:

1. Skin Tac Wipes – a sticky barrier wipe that enhances adhesion
2. IV Prep Wipes – ideal for sensitive skin, helps clean and prep
3. Flonase (used off-label) – some users find it reduces irritation under sensors
4. Adhesive Remover Wipes – for gentle removal without damaging the skin
