Causes of skin spots 1. Internal cause 1. Stress: When people are stressed, they will secrete adrenaline to prepare for stress. If you are under stress for a long time, the balance of human metabolism will be destroyed, the supply of nutrients needed by the skin will tend to be slow, and the pigment mother cells will become very active. 2. Hormone secretion disorder: The female hormone estrogen contained in contraceptives will stimulate the secretion of Melanie cells and form uneven spots. Although the spots formed by birth control pills will stop after stopping taking drugs, they will still stay on the skin for a long time. During pregnancy, due to the increase of female hormone estrogen, spots are easy to appear from 4-5 months of pregnancy, and 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 will deepen the spots. Sometimes new spots will not disappear after delivery, so you need to pay more attention. The spots that grow out because of hormone secretion disorder can be treated with some professional drugs, such as Meng Kang activating skin and amino acid tablets. These are professional drugs that regulate spots from the inside, and the curative effect is remarkable. 3, slow metabolism: spots will also appear when liver metabolic function is abnormal or ovarian function declines. Because of poor metabolism, or endocrine disorders are in a sensitive state, the pigment problem is aggravated. Constipation can form spots, which is actually caused by allergies caused by endocrine disorders. When the body state is abnormal, ultraviolet rays will also accelerate the formation of spots. 4, the wrong use of cosmetics: the use of cosmetics that are not suitable for your skin, leading to skin allergies, such as excessive exposure to ultraviolet light during treatment, skin in order to resist external aggression, will gather melanin pigments in the inflamed parts, leading to pigmentation. Second, external factors 1. Ultraviolet rays: when irradiated by ultraviolet rays, the human body will produce a large amount of melanin in the basal layer in order to protect the skin. Therefore, in order to protect the skin, more pigments will gather in sensitive parts. Frequent exposure to strong sunlight will not only promote skin aging, but also cause pigmentation skin diseases such as black spots and freckles. 2, bad cleaning habits: because of strong cleaning habits, the skin becomes sensitive and will stimulate the skin itself. When the skin is sensitive, in order to protect the skin, melanocytes will secrete a lot of melanin. When there is too much pigment, there will be skin pigmentation problems such as spots and flaws. 3. Heredity: If my parents have long spots, I have a high probability of long spots. This situation can be judged to be genetic to some extent. Therefore, people at home, especially those with spots on their elders, should pay attention to avoiding ultraviolet radiation, which is one of the important factors causing spots. This is necessary to prevent spots, but also to use more whitening cosmetics suitable for your skin. The so-called "spot" refers to the skin surface, irregular shape, no uplift but colored rash phenomenon, which belongs to pigmented skin problems. Cognitive differences of "freckle removal" at home and abroad: Domestic reasons: There are many factors, besides melanin deposition caused by sun exposure and improper use of cosmetics, there are also facial spots caused by various pathological pigment metabolism disorders. In addition, dysfunction of zang-fu organs and stagnation of qi and blood are also the main factors. Treatment: internal and external combination. It can be treated by external instruments and drugs, or by adjusting the balance of yin and yang in the body, dredging meridians, promoting blood circulation and removing blood stasis, so as to achieve the effect of removing spots and caring skin. Features: there are many choices for freckle removal. Specialized freckle clinics in hospitals and beauty salons also have corresponding Chinese medicine freckle treatment courses, and patients can choose advanced laser plastic surgery to achieve freckle effect. External causes: excessive sun exposure. Ultraviolet rays in the sun make the pigment cells in the basal layer of skin epidermis active, accelerate the production of melanin, and lead to skin blackening or black spots. Treatment: external treatment is the main method. Using laser and other high-tech plastic instruments to remove facial spots, or using high-tech whitening and freckle-removing products, can affect the production of black Qin, help cell metabolism, and play a role in diluting melanin and freckle-removing. [Edit this paragraph] Classification of freckles: 99% come from heredity and are formed at the age of 5-6. It is quite common in white people with blue hair, but it is also common in Asians. The onset age is before puberty, and the light brown spots with the size of about 65438±0 ~ 2nm are produced in the sun. The size, quantity and pigment depth increase in summer and get better in winter. Chloasma: also known as butterfly spot and liver spot, it is light brown flake with different sizes, clear boundary, irregular shape, not higher than skin, common on face and symmetrical cheeks. The main reason is related to the imbalance of endocrine and female hormones. Sunburn: As the name implies, it is caused by sunbathing, so it is common in middle-aged people in their forties and fifties, both men and women, but some people have grown up as early as their twenties and thirties. Sunburn is a well-defined brown-black spotted lesion in clinic, which can be as big as sesame or as big as a ten-dollar coin. The most common parts are face, back, chest, upper and lower limbs, but facial lesions are bigger and more obvious. & gt& gt& gt, please click
