After a few recovery sessions, you may see a loss of adhesion of the Firefly gel. Some of this may due to skin particles or hair attaching to the surface of the gel. It can also be due to the loss of moisture from the gel. You can rehydrate the gel by sprinkling a little water onto the gel or lightly misting the gel with water. Do not add too much water as it could have the opposite effect and damage the gel. It is safe to sprinkle water on the firefly device, but do not submerge it in water.
