In structure, receptors can be divided into two groups: free nervous endings and specialized receptors. They are associated with sensitive (afferent) nerves with a spinal and brain and constantly send signals about the state of their environment.
Light pressure and cold are perceived below the surface, end nervous devices that feel warm and strong pressure are more deeply. Receptors are linked by sensitive (afferent) nerves with a spinal and brain and constantly send signals about the state of their environment. Receptors are connected with sensitive (afferent) nerves with spinal and head The brain and constantly send signals about the state of their environment.
Specialized receptors numb five types
– End flasks Krause are located in the dermis, perceive cold
– Taurus pachinas are located deep in the skin and subcutaneous tissue and are sensitive to displacement of the skin at pressure.
– The tent of the ruffini lie in deep layers of the dermis and hypoderma (perceived heat), are branches of flattened nerve fibers.
– Merkel cells are located in the basal layer of the epidermis and perceive constant pressure.
– Maissener Taurus is under the epidermis in the upper layer of the dermis, react to the displacement of the skin when touched.
The epidermis is free nervous endings sensitive to mechanical, thermal, cold and pain irritation. In the deep layers of the skin there are nervous endings of hair follicles. The most sensitive are the lips and fingertips that contain more nerve endings.
Leather. Color of the skin
The skin color is caused by three pigments: brown melanin, yellow carotene and red hemoglobin blood pigment. Their combinations form an individual complexion. The tone translucent through thin skin determines whether it belongs to a warm or cold type (for details, see the chapter “Definition of skin type”). Individual complexion is due to the combination of all three pigments.
Leather. Derivatives
The skin derivative includes:
– hair that is distributed almost throughout the surface of the skin;
– nails that play a secondary role in our topic;
– sal glands, which are in close proximity to the hair follicles, especially in the areas of sobs on the face, chest and back;
– Potions, which are located in the epidermis, their about two million.
Pathology of the skin
In people who want to make permanent makeup, there are often diseases and changes in skin of exogenous and endogenous origin. Immediately need to emphasize that they are included in the competence of doctors and in the acute stage are not punishable.
For example, skin allergy, eczema, simple herpes – acute states that are subject to PM only after exiting the active phase and treatment with relevant medicines.
In no case cannot be pigmented by sharp skin changes, such as pigment spots, melanoma, papillomas due to the wart virus, fibromes and other skin changes due to the risk of malignant rebirth.
Often small papillomas are found on the edge of the upper century. When pigmarked the clarity edge, you need to work around them, it is not difficult and later will never be noticeable.
In the area of eyebrows, sometimes when pigmented, there are areas of hyperkeratose (excessive orog), in which the skin is thickened. These areas can be treated with a hygienic module, which has a high impact strength. Especially carefully needed to follow the transition of the needle from the boundaries of such a orogue to normal skin, so that the immersion depth of the needle, the uniformity of the color and the thickness of the line has not changed due to the reduction of skin resistance at the hyperacratosis.
Do not pose difficulties with permanent makeup scars on lips and in the area of eyebrows, as a rule, resulting from damage in childhood or at a later time, if only their existence was at least six months.
The exception is the keloid tissue (thickened scar, benignural growth of the connective tissue), which can be changed only by the corresponding surgical treatment.
Strya (stria of pregnant, subcutaneous gaps) in the abdomen, pelvis, chest and thighs caused by a very fast stretching of the skin after an increase in body weight, often annoy their owners. There is an opportunity to hide these ugly scars by pigment by corporal color. Regarding the so-called camouflage pigment, the opinions are diverged. On the one hand, it significantly increases the amount of work and the income of the cosmetologist. For a short time and the client will be pleased with the result. But it is necessary to remember that the dye of the corporal color consists of white dioxide titanium and small additives of the coloring pigment. At titanium dioxide, a small sustainability period, it is unstable in the light. Camouflage pigment is never preserved for a long time, after the collapse of titanium dioxide, the color in most cases will become ugly gray-brown. The acute states of skin diseases are punishable only after treatment with relevant medicines.
Also controversial or, as often spoken, irresponsible, is to carry out the so-called imitation of hair, that is, an optical “seal” of rare hairs at the top of the forehead. They also work with eyebrows, drawing their “hairs to the hairs”.
Since rare hair on the forehead is rare even more, and their border moves back, the pigmented hair additive is shifted forward. Different components of dyes in ultraviolet irradiation differ in stability and, therefore, at the rate of decay. But since in almost every paint for hair, there is some black iron oxide, a cinema-gray pigment residue will always be present in the skin. Pigmenting of acute skin changes (pigment spots, melanomas, papillomas, etc.) can lead to their malignant reincarnation.
Leather. Possible skin reactions on PM
In order to introduce a color pigment into the skin, it is stretched and enter the needle into the top layer. Of course, the skin reacts to these procedures.
How strong is this reaction depends on many factors. Redness and swelling of the processed skin area is a normal phenomenon that usually passes shortly after processing.
The degree of pain is individual and also depends on many reasons. If at this time the client is tense and excited, and before that, perhaps, was something annoyed, the pigmentation will seem more unpleasant to him than at another time. Especially predisposed to pain young women with very sensitive skin, but an experienced specialist who has experience in communicating with people can calm them. A psycho-emotional factor plays an important role here. If the client is careful and he feels trust, his tension will significantly decrease, and he will feel more comfortable.
According to the experience, it is known that if a day before the procedure, the client is intensively sunbathe in a solarium or on the beach, irritation and pain in pigmentation will be stronger.
Possible, but rarely encountered skin reactions with permanent make-up, except for the previously listed normal reactions, are:
Bleeding. Excessive bleeding occurs when the processing is performed at too much depth and with high pressure on the tip of the needle or when there are too thick on the soft tissue of the lips (from the 3rd and above) needle with injective anesthesia. The result in most cases are keloid scars. When working with centuries, blood rarely appears, you only need to continue working with all sorts of precaution. You can stop the blood, wet the damaged place with a cotton swab, imposing a pigment or, if necessary, apply vaseline. Usually experienced masters who work at the domestic depth, when processing the eyelids and eyebrows, blood does not protrude. When performing the lip contour, as practice shows, the opening of the skin
