The Pricking Method Of Tattoo Needle Is Related To The Skin

Tattoos seem to be made on the skin of the human body, but this is not just a superficial art, but integrated into the body.

Human skin is divided into three layers, including "epidermis", "dermis" and "subcutaneous tissue". Epidermis is the outer layer of human and animal skin. It is formed by ectoderm in embryonic stage. It has anti friction and anti damage effects. Epidermis is the superficial structure of the skin, which is composed of stratified flat epithelium. From the basal layer to the surface, it can be divided into five layers, namely basal layer, spinous layer, granular layer, transparent layer and cuticle. The dermis is located in the deep layer of the epidermis, which is connected with the subcutaneous tissue downward, and there is no obvious boundary with the latter. There are various connective tissue cells and a large number of collagen fibers and elastic fibers, which make the skin both elastic and tough. The thickness of the dermis is different. The dermis of the palm and sole is thicker, about 3mm or more, and the eyelid is the thinnest, about 0.6mm. Generally, the thickness is between 1-2mm. If the skin is damaged, we will see the red skin under the epidermis and feel the pain. This layer is dermis. Subcutaneous tissue is also called "subcutaneous adipose tissue". Subcutaneous adipose tissue is a loose layer of tissue. It is a natural cushion that can cushion external pressure. At the same time, it is also a hot insulator that can store energy. In addition to fat, subcutaneous adipose tissue is also rich in blood vessels, lymphatic vessels, nerves, sweat glands and hair follicles.

Our epidermal skin has no blood vessels. The metabolism of the lower layer will be gradually transplanted upward, while the most superficial skin (epidermis) will gradually fall off, and the epidermal skin will recover naturally even if it is injured. Therefore, in theory, if the tattoo simply stabbed in the epidermis can be eliminated automatically within a period of time, but this is probably a very difficult operation. First of all, It is very difficult to make the tattoo needle not touch the dermis at all, and it is even more difficult to work on the epidermis to prick beautiful works.

Usually, the color of normal tattoos is stabbed on the dermis, but the pigment particles left on the dermis cannot be simply eliminated, just like the principle that scalds are not easy to recover. Tattoos see the patterns on the dermis through the epidermal skin. In addition, most tattoos, the pigment particles of color have gone deep into the subcutaneous tissue of people, so basically speaking, tattoos are difficult to remove from the outline.

Some originally beautiful tattoo works become lighter in color or blurred in pattern after a few years, that is, in the tattoo operation, the pigment does not really go deep into the dermis, and falls off with the epidermis due to metabolism. Therefore, the reasons for not coloring or fading are not only the advantages and disadvantages of using pigments, but also the operation. Using irregular pigments, in addition to not stabbing fresh works, because pigment particles will go deep into subcutaneous tissue, which will cause serious consequences. This is also an important reason why tattoos should pay attention to health and safety
