A woman's neck, as white as ivory and as smooth as velvet, should not be too thin and too thin. A plump neck is more sexy. There is a saying in The Book of Songs: "The collar is like a cricket", which is the first time that China talked about the beauty of a woman's neck. The collar is the neck, and the salamander is the larva of longicorn and mulberry cattle. It is milky white, long and plump. "The collar is like cricket" means that the neck is as white and plump as concrete. Modern aesthetics holds that a woman's neck should be slender and aesthetic. According to the morphological characteristics of the neck, it can be divided into normal neck, slender neck, thick and short neck, probing neck, upturned neck, torticollis and necking. A normal neck has the following characteristics: the neck is suitable for protrusion, the bending moment is 3-5cm, the neck thickness is coordinated with the head size and shoulder width, and the length of the head and neck is about 65438+ 0/6 of the height. Normal people When standing upright, both sides of the neck are symmetrical, the length and thickness are commensurate with the figure, the thyroid cartilage area is flat and not exposed, and the sternocleidomastoid muscle is slightly prominent and the blood vessels are not exposed when leading the neck. The female neck is slightly slender, smooth and delicate, with a small Adam's apple and a high position. The thyroid gland in the lower part of the neck is more developed than that in men, so the neck looks thin and thick from the side. The sternocleidomastoid muscle in women is not as obvious as that in men, and the supraclavicular fossa is shallow. Women's neck skin is fair and delicate, so it is called "Jade Neck". Another feature of the female neck is that there are three horizontal wrinkles at the back of the neck, which are 3 ~ 4 cm away from the mastoid process. They are called "Venus" collars, which is a unique aesthetic representation of women's necks. The Adam's apple of men is about 30% larger than that of women, and its position is lower; The thyroid gland of women is more developed than that of men. All these characteristics began to appear after puberty and were full of sexy aesthetic characteristics. In addition, the neck should be straight and not skewed, plump and not bloated, the skin should have tension and elasticity, the neck chin angle should be harmonious and clear, the neck movements should be flexible, and the neck circumference should be in proper proportion to the height. According to human anatomy, a normal person's neck is upright and symmetrical on both sides. A stout person is short and thick, and a lanky person is slender. Male thyroid cartilage is prominent, while female flat is not obvious. You can see sternocleidomastoid muscle and carina when you turn your head, but people with normal neck blood vessels will not be exposed when they sit still. If the head can't be lifted, it means that the neck muscles are weak, mostly myasthenia gravis, progressive muscular atrophy and chorea. Because the neck is a triangular area in anatomy, the tissue structure is weak, especially the skin and subcutaneous tissue of the anterolateral neck, and the skin and subcutaneous fat at the back of the neck are thick, so the neck bone is often exposed, and the anterolateral neck is full of pits. Obesity, combined with long-term inactivity, and relaxation and obesity behind the neck give people the feeling of aging before they get old. According to the observation of medical scientists, women's neck fat is more likely to accumulate than waist and buttocks. People who lack exercise and work at their desks for a long time are most likely to lose neck muscles. Both men and women don't like their double chins. The double chins are full of fat, which not only affects the appearance, but also makes the excess fat "shake" with the body, giving people a very unhealthy feeling. In addition, many people think that aging begins with the face, but when the skin around the eyes is still very delicate, the neck has already shown signs of aging-the appearance of fine wrinkles, which makes women very nervous. The skin on the neck is very thin and fragile. The number of sebaceous glands and sweat glands in the skin in front of the neck is only one third of that in the face. Sebum secretion is less, it is difficult to moisturize and it is easier to dry, so it is easy to produce wrinkles. There are usually two kinds of wrinkles on the neck. One is the wrinkles of early aging, which began to appear in the teens. This kind of wrinkle is usually not obvious. Another wrinkle is affected by ultraviolet rays and deepens with age. This wrinkle may be very obvious. Countless movements of raising the head and lowering the head, together with the weight of supporting the head, can easily accelerate the aging and relaxation of the neck skin and produce wrinkles. Moreover, once wrinkles are produced, it is difficult to restore elasticity and eliminate them. Many women attach great importance to the maintenance of "face" and "pile up" all kinds of skin care products on their faces without stint, but they don't care much about the neck skin, so some girls have obvious wrinkles on their necks from the age of 25. If you are older, the neck skin has been slack and dehydrated, and the sense of contour has decreased, which requires targeted neck maintenance. Many people tend to ignore the decoration of the neck, or pay attention to the skin color of the face and neck, or simply forget the neck completely. In this way, there is a very obvious color difference between the face and the neck, especially for people with black and yellow skin color. The light and tender face has been carefully decorated, which makes the whole makeup look more and more black and yellow against the unmodified neck, which is extremely uncoordinated and even eclipsed, losing the sense of nature and realism. This negligence is really a low-level mistake in makeup technology. Therefore, when applying foundation, we should habitually consider the neck and face as a whole. If there is little difference in skin color between the two, you can directly apply white powder after applying skin cream to the neck; If the color difference is obvious, it is necessary to extend the facial foundation to the neck and apply it evenly. During this period, pay attention to the natural redundancy and smudge, so that it will be colorless, and finally apply makeup powder, so that the modified facial makeup will be harmonious and lasting.
