Tattoo Goo® is a natural Olive Oil-, Cocoa Butter- and Wheat Germ-based salve. It does not contain harmful chemicals that can sometimes cause reactions in some people. Olive Oil, especially the pomace grade used by us, is considered the best of natural humectants. Tattoo Goo® products contain no petroleum. Petroleum also contains many impurities that can also clog skin pores and prevent the tattoo from breathing. Tattoo Goo® Salve contains no lanolin. Lanolin is highly allergenic. Tattoo Goo® was specifically developed for healing tattoos. Chemicals used in other products such as A&D, Triple Antibiotic and Bacitracin may often cause problems during the healing process.
