Chemistry of Tattooing

How are tattoos permanent?There are several layers of skin. The top layer is called the "epidermis". The epidermis continously sheds and creates new skin. Now, the second layer is known as the "dermis". The dermis is stable. Tattoos are usually injected into the dermis where it will be permanent.

What is a tattoo?A tattoo is a puncture or a wound made deep in the "dermis", aka. the second layer of your skin which is stable and will not shed.

Risks of Tattooing:-You are putting yourself at risk for getting viral infections such as hepatitis, bacterial skin infections, or dermatitis (severe skin irritation) if you do not get the tattoo in a clean environment.-People with eczema may have allergic reations toward the ink. -viruses such as HIV and hepatitis B and C can be transferred into your body if correct injections are not used.-When getting a tattoo, be careful and cautionous about where you are getting it and who you are getting it from.

Tattoo Removal:-Before, since the tattoo was drawn in the dermis, it was nearly immpossible to remove a tattoo. But modern technology makes it easier.-Today, we use laser beams!-When the lazer hits the pigment inside your skin, it weakens the ink, allowing your immune system to wash it away

Tattoo Ink: -made up of pigments and carrier molecules-pigments are suspended in carrier solutions-different pigments in tattoo ink makes all the different colors-carrier molecule keep the mixture evenly mixed, and to make it easier to apply.

-different colors are made of different pigments and different elements. Example: Black Ink. Made of: Iron Oxide(Fe3O4), Iron Oxide(FeO), Carbon, and Logwood

Modern Tech Tattooing:-A small hand held device used to create a tattoo-uses electromagnetic coils to move an armature bar up and down- Connected to the armature bar is a barred needle grouping that pushes ink into the skin-does not use any kind of electricity, just force.-functions similar to a "gun"
