Tattoos are actually a kind of minimally invasive skin coloring. It is not clear whether they belong to medical beauty or life beauty. Is to implant pigment into skin tissue to form a stable color block. Because the epidermis is very thin and translucent, the implanted pigment presents the implanted color through the epidermis, thus covering up the defects, fostering strengths and avoiding weaknesses, and playing a beautification role.

Because the pigments infiltrated into the skin are small particles with a diameter less than 1 micron, they are quickly surrounded by collagen after implantation, but they will not be swallowed up by cells, thus forming semi-permanent marks on the skin surface. It is also called "embroidery" or "Wen Xiu" or "Shi Wen".

Generally speaking, skin is divided into epidermis and dermis, and its thickness varies from 0.2 12 mm to 0.508 mm according to different parts, with the thinnest in the eyes and the thickest in the palm.

Knowing the thickness of the skin and the depth of the needle when tattooing, you can be sure that the tattoo will not be too deep or too shallow. The top layer of epidermis consists of stratum corneum and dense squamous cells, followed by transparent layer, granular layer, spinous layer and mucus layer. There are no blood vessels in the epidermis, but there are many tiny nerve endings, and the epidermis is basically translucent.
