MICROANATOMY

Detailed explanation-1: -The oscillating ink-coated needle punctures the skin in the range of 100 times per second, depositing the ink pigments 1.5 to 2 mm below the skin surface. Thus, the needle penetrates the skin through the epidermis and into the papillary layer of the dermis, where the ink particles accumulate.

Detailed explanation-2: -The dermis, a connective tissue made up of collagen and networks of elastic fibers which give skin its resiliency, is the layer in which tattoo ink is deposited. The dermis (papillary layer) immediately below the epidermis is made of loose connective tissue and contains small blood vessels and nerve endings.

Detailed explanation-3: -Guess how tattoos stay there forever, even as your skin cells die and are replaced? French researchers say they have found the answer, and it’s a little bit surprising. They found that immune system cells called macrophages eat the ink, and then pass it to their replacements when they die.
