First check:
Wash skin with soap and water. Make sure the area is totally dry before applying.
Remove excess hair.
Avoid applying on bendable areas (around joints or small areas.)
Avoid excess sweating. (The patches do not “breathe” with the polymer backing. Sweat and oil will cause the patch to separate from the skin.)
In rare cases, some clients’ skin is not compatible with the adhesive, it either sticks too well or not well enough. If you’ve tried troubleshooting steps 1-4, perhaps the muscle cream is a better option for you!
