Or would it be useless if its been exposed to open air for at least a few days?
Aha ha haha hah! Oh that was a good laugh... Both matrix and gel types are "adhesive," which describes the glue used to make the patch stick. Gel is a thicker patch with a gel resivoir that leaks out while the matrix is a flat surface that holds the substance evenly and honestly I have no clue how it slowly releases over 3 days.They were the adhesive kind, not the gel (I've always preferred the adhesive ones anyway).
