If you’ve ever had a CGM patch peel off before your sensor cycle was finished, you’re not alone. Knowing what affects CGM patch duration can help you get the best out of every patch - without wasted sensors or stress.
Below, we answer how long a patch should last, what impacts patch hold time, and how to get the full advertised wear from your patch.
What is the typical CGM patch duration?
For most Type Strong users, CGM patch duration is up to 10 days.
This matches the cycle of leading CGM devices like Dexcom G6 and G7, and allows for secure, confident wear throughout normal daily activities.
Patch hold time can vary based on:
- Which device you use
- How much you sweat or swim
- Your skin type and how you prep
- The patch’s adhesive quality
Using a patch not made for your device, or skipping steps in proper skin prep, can lead to early lifting.
Should patch hold time always match sensor life?
For most CGMs, yes.
Type Strong patches are designed for up to 10 days of reliable hold, which aligns with the typical sensor life for devices like Dexcom G6, Dexcom G7, and Medtronic Guardian 4.
For longer-wear sensors like Freestyle Libre (14 days), you may need to replace the patch once during the sensor cycle for best results.

If your patch lifts before 10 days, it may be due to skin prep, activity, or environmental factors. For troubleshooting, see 5 signs your CGM patch is too weak for daily life.
Why do patches sometimes peel early?
Early peeling is often caused by:
- Skipping essential skin cleaning and drying
- Applying over moisturiser, oil, or sunscreen
- Intense activity or swimming shortly after application
- Using a patch not designed for your device
Find out how proper skin prep can help patches last their full advertised duration.
How to maximise your CGM patch duration
Follow these tips for up to 10 days of secure wear:
- Wash and thoroughly dry the application site before use
- Avoid lotions or sunscreen at the site
- Press and smooth the patch firmly for 30–60 seconds, making sure edges are fully sealed
- Wait at least an hour before swimming or vigorous activity
- Keep spare CGM patches handy for quick replacement if you experience early lifting
Always patch test if you have sensitive skin.
Frequently Asked Questions
- How long will my Type Strong patch last? Our adhesive patches are designed for up to 10 days of hold, matching the cycle of most CGM devices. Your wear time may vary with skin type and activity level.
- Why did my patch lift after only a few days? Early lift is most often due to skin not being fully clean or dry, or heavy activity soon after application. Using proper skin prep helps maximise wear.
- Can I use one patch for the full 14-day Freestyle Libre cycle? You may need to replace your patch during the 14-day cycle, as each patch is tested for up to 10 days’ reliable hold.
- Is it safe to use waterproof patches every time? Our patches are water-resistant, but heavy, ongoing exposure may reduce hold time. If you notice irritation, discontinue use and consult your healthcare provider.
- Do certain activities reduce patch hold time? Yes - intensive exercise, friction, or regular swimming may shorten your patch’s wear. Plan your routine and patch bundle accordingly.
- What if I have a skin reaction? Stop using the patch and consult your healthcare provider. See CGM patch reactions for more advice.
