For best results, clean and dry the area thoroughly, peel back the clear top layer, and place on the skin. If you don’t plan on using it immediately, store in a cool, dry place. Use and storage: The Transdermal CBD Patch works best next to a vein. You can place it on your inner arm, top of your foot, the front of the hips, or wherever is most comfortable. For maximum relief try cutting it and putting behind the ear or placing it on the small of your back.
