The significance of moles and spots in physiognomy
|
Moles and spots are both a kind of pigment that appears on the surface of the skin and can be seen with the naked eye. Generally speaking, many people cannot distinguish clearly between moles and spots on the face. In fact, moles and spots are very easy to identify. The Mole Illustrated Book will introduce you to the differences between moles and spots. Friends who can’t tell the difference, come and learn some knowledge!
The significance of moles and spots in physiognomy <br />Sometimes you can see some brown or gray dots on the surface of the skin. These dots may be moles or spots, and almost everyone has them. Moles can be found in a wide range of locations and can occur on the skin and mucous membranes of any part of the body. They can be congenital or acquired. The area where the spots are located is relatively smaller, and most of the spots are acquired. Some larger spots and moles look very similar, but it can be difficult to tell them apart if you don't know enough about the characteristics of moles and spots. Here are some of my ways to tell the difference. Mole is the most common benign skin tumor in humans and is a skin manifestation caused by an increase in the number of melanocytes. Depending on the location of nevus cells in the skin, they can be divided into junctional nevus, mixed nevus and intradermal nevus. Junctional nevus are characterized by being flat and deposited between the dermis and epidermis, intradermal nevus are characterized by being papilloma-like, hemispherical and with melanin deposited in the dermis, and mixed nevus are characterized by being slightly elevated and having both of the above properties. Moles can occur on the skin and mucous membranes of any part of the body and can be either congenital or acquired. It is in the form of flat or slightly raised macules or maculopapules, or may be hemispherical, papilloma-like or pedunculated, with a smooth surface, with or without hair, and may be single, a few, or dozens in number. Due to the different types and contents of pigments in nevus cells, nevus can be brown, brown, blue-black, black or dark brown. Non-pigmented nevus are mostly skin-colored. Spots are generally caused by different physical constitutions or by some inducing factors of the human body (such as ultraviolet rays, endocrine disorders, etc.). The essence of spots is that the human melanin gene mutates or is damaged, causing melanin to be deposited in the basal layer of the skin. The spots vary in shape and size and there are many types. In comparison, moles are darker and protrude from the skin, while spots are lighter and paler in color. Factors that cause moles: 1. Moles are formed by nevus cells containing melanin and exist on the skin surface in different shapes and sizes. Depending on the different layers of the skin where melanocytes are located, they can be divided into intradermal nevi, junctional nevi, and mixed nevi. There are many moles on the surface of a normal person's body, which are closely related to melanocytes. 2. Internal factors: hormonal imbalance, medication (such as birth control pills), pregnancy, mental stress, etc. 1. Endocrine disorders. The production of melanin is affected by changes in sex hormone levels during menstruation and pregnancy. In addition, endocrine instability usually causes emotional instability, which can also indirectly cause the formation of moles (in traditional Chinese medicine, the formation of melasma is mainly attributed to liver congestion, which is more complicated). 2. Autosomal inheritance. Symptoms usually begin in children around 5 years old, mostly in women, with severe symptoms in spring and summer and mild symptoms in autumn and winter. Light brown to yellowish brown spots ranging in size from pinpoints to rice grains, etc., cause the formation of moles. 3. External factors: epidermal irritation, ultraviolet radiation, massage, acne marks, etc. 1. Bad living habits. Another reason for the formation of moles is bad lifestyle habits, such as stress, picky eating, and lack of sleep. Therefore, people with unstable sleep schedules have poor skin metabolism, which directly affects the production of melanin. 2. Strong ultraviolet radiation. Do you know why women need sunscreen? This is because ultraviolet rays in sunlight are an important cause of mole formation. When the skin is exposed to too much sunlight, the epidermis produces more melanin particles, which can absorb ultraviolet rays and protect the human body from harm. This is why your skin becomes darker after sun exposure. Moreover, ultraviolet radiation can make ordinary freckles darker in color. 4. The appearance of moles is mainly related to the source of melanocytes. One reason is that the melanocytes in moles come from neural tissue and develop during the embryonic period. Because there are clinical cases that can prove that patients with large intradermal nevi have no pain in the lesion site, which can indicate that it is related to the nerve tissue. 5. Black moles are produced by a group of benign melanocytes that gather at the junction of the epidermis and dermis. The melanocytes in moles may be distributed between the connective tissue bundles in the lower reticular dermis, surrounding other accessory organs of the skin such as sweat glands, hair follicles, blood vessels, nerves, etc., and occasionally extend to subcutaneous fat. Moles may appear flat, raised, warty, granular, or other shapes, and may be brown, black, or blue in color. 6. Another reason is that they come from epithelial cells and are a functional degeneration of ordinary basal cells, because experiments have shown that if the skin is irradiated with X-rays, nearly 50% of the basal cells may mutate and become dendritic cells. No matter which statement is correct, the impact on people is actually very low, because moles grow slowly, and many small moles can be found on a normal human body, which has no impact on people's lives. The factors that induce spots are: 1. Internal factors 1. Improper use of cosmetics: Using cosmetics that are not suitable for your skin will cause skin allergies. During the treatment process, if the skin is exposed to excessive ultraviolet rays, the skin will accumulate melanin in the inflamed area in order to resist external invasion, which will cause pigmentation problems. 2. Hormone imbalance: The female hormone estrogen contained in contraceptives will stimulate the secretion of melanin cells and form uneven spots. Although the spots formed by contraceptives will stop after the medication is discontinued, they will still stay on the skin for a long time. Due to the increase in the female hormone estrogen during pregnancy, spots are more likely to appear from the 4th to 5th month of pregnancy. Most of the spots that appear at this time will disappear after delivery. However, abnormal metabolism, skin exposure to strong ultraviolet rays, mental stress and other reasons can make the spots darker. Sometimes new spots will not disappear after delivery, so you need to pay more attention to them. 3. Stress: When people are under stress, they will secrete adrenaline to prepare for dealing with the stress. If you are under stress for a long time, the balance of your body's metabolism will be disrupted, the supply of nutrients needed by the skin will slow down, and the pigment stem cells will become very active. 4. Slow metabolism: Spots may also appear when the liver's metabolism is abnormal or the ovarian function is impaired. Pigmentation problems are exacerbated because the body is in a sensitive state due to poor metabolism or endocrine disorders. Constipation can cause spots, which are actually caused by endocrine disorders leading to allergic constitution. When the body is in abnormal condition, exposure to ultraviolet rays will also accelerate the formation of spots. For example: crow's feet with spots: low thyroid immunity; spots under the eyes: female hormone imbalance, uterine disease, too many miscarriages or taking birth control pills; Spots on cheeks: weak liver, ultraviolet radiation, insomnia; Spots around the corners of the mouth: uterine, ovarian and gynecological diseases; Neck: caused by perfume allergy; Hairline: Caused by internal organs or hair dyeing, poor liver function. 2. External factors 1. Genetic genes: If one of the parents has spots, the probability of the individual developing spots is very high. This situation can be determined to be the effect of genetic genes to a certain extent. Therefore, those who have freckles at home, especially the elders, should pay attention to avoid ultraviolet radiation, which is one of the important factors causing freckles. This is what you must pay attention to in order to prevent spots, and you should also use more whitening cosmetics that are suitable for your skin type. 2. Ultraviolet rays: When exposed to ultraviolet rays, the human body will produce a lot of melanin in the basal layer in order to protect the skin. Therefore, in order to protect the skin, more pigments will accumulate in sensitive areas. Frequent exposure to strong sunlight not only promotes skin aging, but also causes skin diseases such as dark spots and freckles due to pigmentation. 3. Bad cleaning habits: Strong cleaning habits make the skin sensitive, which will irritate the skin. When the skin is sensitive, the body's melanocytes will secrete a lot of melanin in order to protect the skin. When the pigment is excessive, skin pigmentation problems such as spots and blemishes will appear. The above is an introduction to the significance of moles and spots in physiognomy.
