Instant cold or gel packs are among the items that most experts say should be included in a well-stocked first aid kit.
But, while instant cold or gel packs are easy to store and are more convenient than ice, experts say that they may damage the skin because of the cold temperatures they reach. Because ice doesn't get as cold, it is safer, and thus preferable to cold or gel packs.Thus, if you are going to use a gel pack, make sure to use it over clothes or wrapped in a towel.
