A tattoo, or otherwise known as dermal pigmentation, is a permanent mark, pattern, or design created by inserting pigments into the second layer of the skin. It is done by pricking the skin with specially designed needles dipped into indelible ink. Tattoos on human are some form of artistic body modification, while tattoos found on animals are used for branding or identification.

Tattooing is practiced worldwide. Japan's indigenous people called the Ainu have been wearing facial tattoos. Polynesians, and particular tribal groups in Borneo, North America, Philippines, Africa, Mesoamerica, South America, Cambodia, Europe, China, and Japan are into tattoos. Albeit some taboos surrounding the creative world of tattooing, the art still manage to be popular and in demand all throughout the world.

The human skin is constituted of three layers namely: the epidermis, the dermis, and the subcutaneous tissues. The epidermis is the topmost layer with no blood vessels and serves as a protective barrier. Second to the epidermis is the dermis. This is a thick layer and this is where the tattoos are formed. Since the epidermis is constantly replenished, with the top skin continually shedding off in a lifetime, the tattoo is pushed deeper into the dermis where it is expected to stay undeterred the whole time.

Tattoo needles penetrate into the skin for about 1.5 millimeters or 1/16 of an inch deeper. The tattoo artist must ensure that the ink goes just enough to be permanent and not deeper than necessary. The depth differs in certain areas of the body, like it is thinner on places like the genitals and deeper on the feet's soles.

If a tattoo is too deeply made reaching the subcutaneous tissues, it causes bleeding and pain. It will also appear blurry even after it has healed. And if just a few millimeters beneath the epidermis, it leaves scratches and just wear off.

Learning about tattooing may take several years to master if you really intend of becoming a tattoo artist. Therefore, it is vital that you carefully choose a tattoo artist with more experience and already with a great portfolio of his or her works that clearly show excellent quality.

A tattoo is as pretty and captivating as the artist who did it.
