Sexy Women Tattoo and Butterfly Art Tattoo DesignWhat Is a Tattoo?
Let's quickly remind ourselves exactly what a tattoo is: A tattoo is a permanent mark or design made on the body when pigment is inserted into the dermal layer of the skin through ruptures in the skin's top layer.
Modern-day tattoos are applied by using an electric tattoo machine with needles that rapidly puncture the skin with an up and down motion not unlike that of a sewing machine.

How Do Lasers Remove Tattoos?
How Do Lasers Remove Tattoos
Lasers work by producing short pulses of intense light that pass harmlessly through the top layers of the skin to be selectively absorbed by the tattoo pigment. This laser energy causes the tattoo pigment to fragment into smaller particles that are then removed by the body's immune system. Researchers have determined which wavelengths of light to use and how to deliver the laser's output to best remove tattoo ink. (If you're wondering if the laser might also remove normal skin pigment, don't worry. The laser selectively targets the pigment of the tattoo without damaging the surrounding skin.)
Tattoo inks
Modern tattooing inks are carbon based pigments that have uses outside of commercial tattoo applications. Although the United States Food and Drug Administration technically requires premarket approval of pigments it has not actually approved the use of any ink or pigments for tattooing (because of a lack of resources for such relatively minor responsibilities).[citation needed] As of 2004 the FDA does perform studies to determine if the contents are possibly dangerous, and follow up with legal action if they find them to have disallowed contents, including traces of heavy metals (such as iron oxide) or other carcinogenic materials (see CA lawsuit). The first known study to characterize the composition of these pigments was started in 2005 at Northern Arizona University (Finley-Jones and Wagner).
The FDA expects local authorities to legislate and test tattoo pigments and inks made for the use of permanent cosmetics. In California, the state prohibits certain ingredients and pursues companies who fail to notify the consumer of the contents of tattoo pigments. Recently, the state of California sued nine pigment and ink manufacturers, requiring them to more adequately label their products.Dragon Tattoo Design
