A word or two about Iodine based solutions in regards to cleaning fresh Body Piercings. Iodine based products have never been well suited for cleaning fresh Piercings. Especially above the neck, where they can cause serious problems in and around the eyes and ears.
Surgeons also use it as a pre-surgery hand cleanser.
It is intended for use on Non-Broken skin. Of course anyone with an Iodine allergy or sensitivity could not use these products. If an Iodine solution is left in contact with the skin for prolonged periods of time, a sensitivity problem may develop. This is called Contact Dermatitis. Some Iodine solutions also contain Citric acid.
