Embroidery is actually a kind of minimally invasive skin coloring. It belongs to medical cosmetology. It is the pigment implanted into the skin tissue to form a stable color patch, because the epidermis is very thin, translucent, so the implanted pigment through the epidermis presents an implanted color, in order to cover up defects, to avoid weaknesses, modify and beautify the role. Because the pigments penetrated into the skin are small granules with diameters less than 1 micron, they will soon be surrounded by collagen and unable to be phagocytized by phagocytes, thus forming a semi-permanent marker on the skin surface. Known as "embroidery", it is also "Wenxiu" and "decorations".
