Tattoos are actually a kind of minimally invasive skin coloring, which does not belong to medical 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. The following is the basic knowledge of tattoos I have collected. Welcome to read the reference.

Basic knowledge of tattoo

I. Basic principles

Generally speaking, the skin is divided into epidermis and dermis, and its thickness varies according to different parts, about 0.2 12mm-0.508mm, with the thinnest eye and the thickest skin in the palm. Knowing the thickness of the skin, you can determine the depth of the needle when tattooing, so as not to tattoo too deep or too shallow. The bottom layer of epidermis is stratum corneum, which is composed of dense squamous cells, followed by transparent layer. There are no blood vessels in the epidermis, but there are many tiny nerve endings. The epidermis is basically translucent. Near the epidermis is the dermal papillary layer, which is the dermal vascular plexus. Beneath it is the dermal reticular layer and subcutaneous tissue. There are abundant deep vascular plexus and subcutaneous fat, which provide and transport nutrients for the skin.

Tattoo permanent makeup 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.

Second, tattoo common sense

Tattoo ink is a kind of traumatic skin coloring, which has certain risks. Tattoo cosmetology can only succeed but not fail, so the operation of tattoo cosmetology should be carried out under safe conditions. Special instruments and tools are required for disinfection and hygiene, and tattoo operators are also required to have certain basic knowledge of medicine and aesthetics and well-trained operating skills. Environment, atmosphere and light are all important conditions related to tattoo beauty.

Clean and comfortable environment, tattoo beauty is implemented in dermis and epidermis. After the epidermis is punctured, the protective function decreases and bacteria are easy to invade. Therefore, the operation room of tattoo beauty should be kept clean and the air is fresh.

Quiet and soft atmosphere, good atmosphere, can mediate the nerves of good people, make people feel calm and emotionally stable. In this environment, you can concentrate on tattooing. Tattooists actively cooperate in a good environment to ensure the quality of the tattoo artist's work.

Moderate lighting is an important condition for tattoo cosmetic surgery. Soft and comfortable light can reduce the visual fatigue of people with few tattoos and ensure the quality of tattoos.

Necessary facilities: beauty bed and mirror. The tattooer's posture of lying half or lying flat is stable and safe, which is convenient for the tattooer to operate. The function of the mirror is to let the guests see the effect. It is also to let the tattoo artist see the overall effect of the tattoo from the mirror.

Third, the requirements for tattoos.

Meticulous work attitude-Tattoo beauty has certain risks, and a little carelessness or carelessness will affect the quality and even cause accidents. Meticulous working attitude is the guarantee of safety and quality.

Exquisite professional skills-this is the basis of beauty quality. Exquisite technology comes from the training of basic skills, and with solid basic skills, it can be used freely and handy.

The training standard of basic skills-eyebrow tattoo beauty basic training, eyebrow tattoo basic training first. Eyebrow tattooing is the basis of tattooing, which is the most difficult and the easiest. It's easy to say, this part of the skin is slightly thicker, not as sensitive as the skin of eyes and lips, nor as risky as eyeliner. It's hard to say, eyebrows grow into roots, and there is a gap in the middle, so it's difficult to show the virtual and real structure. We should not only make different eyebrow shapes for different people, but also show different shades, so as to present a natural and soft aesthetic feeling.

The basic training standards of tattoo beauty are: stability, accuracy, uniformity and symmetry.

Steady-the tool is steady and the needle is steady. Don't rock back and forth.

Accurate-where the color needle is needed, it falls there, without deviation, and accurately expresses the required content.

Uniform-uniform depth and spacing.

Symmetry-highly symmetrical, length symmetrical, thickness symmetrical, shadow symmetrical.

Fourth, the principles that tattoo surgery should follow.

Pay attention to skills, observe at any time, rather shallow than deep, rather narrow than wide: colors are too uniform and natural, and pay attention to symmetry and overall harmony.

Five, the basic procedure of tattoo

Preoperative preparation stage

Do medical consultation well. Understand the general situation of customers, pay attention to ask about medical history, especially whether there is a history of drug allergy and scar constitution. Observe whether there is inflammation, trauma and scar on the tattoo site. Master the indications and contraindications of tattoo beauty.

Explain the purpose and effect of tattoo, precautions before operation and possible complications. Let customers be psychologically prepared, and never exaggerate the effect on appearance improvement before operation.

Do a good job in the design of tattoo parts and get the consent of customers, and don't arbitrarily and unprincipled agree with the unreasonable requirements of individual customers. We should not blindly pursue the popular fashion design in society, but take a long-term view.

Six, operating procedures

Disinfect the part of skin to be decorated and design the shape.

Prepare tattoo tools, and install and debug tattoo machine. Tattooing needles are disposable sterile and individually packaged needles, which can be discarded after one use. One copy of pigment for one person is prohibited for many people to use.

According to the requirements of the decorative part, mix erotic materials.

Choose a good anesthetic and anesthesia method, and decorate it with the corresponding acupuncture method.

Do a good job in the protection and anti-inflammatory treatment of tattoo wounds after operation.
