Tattoo technique is actually a kind of traumatic skin coloring. Pigment is implanted into skin tissue to form a stable color block. Because the epidermis is thin and translucent, the pigment passes through the epidermis, showing color to cover up defects, foster strengths and avoid weaknesses, and play a beautification role. Pigments that pierce the skin are small particles with a diameter less than one micron, which are quickly surrounded by collagen and cannot be swallowed by phagocytes, thus forming marks. Tattooing is not a simple operation, but rather complicated and skillful, so practitioners must have good professional ethics.
