Olive Oil

Olive oil is a vegetable oil obtained from the fruit of the Olive tree (Olea europaea L.), a traditional tree crop of the Mediterranean Basin. It is used in cooking, cosmetics, soaps and as a fuel for traditional oil lamps. Olive oil is regarded as a healthful dietary oil because of its high content of monounsaturated fat and polyphenols. Extra Virgin Olive Oil makes an excellent lubricant for the stretching of healed piercings, and as a moisturizer for keeping the skin soft and supple.

Also can be found in aftercare products like Tattoo Goo.
