The LifeWave™ patches should be stored in a cool, dry place away from direct sunlight. The storage case that comes with the patches is ideal for this purpose. However, if you are using the patches on a long-term basis, it is important to check the expiration date and replace the patches as needed. expired patches will not be as effective and may cause skin irritation. When not in use, the patches should be kept in their original packaging to protect them from dirt and dust. With proper care, the LifeWave™ patches can provide relief for a wide range of conditions.
