chloasma
Entering middle age, especially after giving birth to a baby, is easy to appear, and the alias is also called liver spot and butterfly spot.

Pictures of various types of spots 2 Classification of spots
Spots are just a general concept, and they all have some similar characteristics, that is, the skin color is dark and uneven, and with the different degree and position of pigmentation, spots are formed on local skin.
According to the different causes, it can be divided into sunburn, chloasma, freckles, senile plaques and traumatic dark spots.
sunburn
Sunburn is medical solar dermatitis, which is an acute reaction caused by sun exposure and a photosensitive skin disease.
chloasma
Chloasma is mostly related to endocrine disorder and visceral dysfunction. It has two kinds: physiological and pathological. Physiological ones are pregnancy spots and uterine liver spots. Pathological is caused by slow metabolism caused by various chronic diseases.
freckle
Freckles are caused by genetic variation of melanocytes.
age pigment
Senile spots are caused by aging of human internal organs.
Traumatic black spot
Traumatic black spots are caused by skin surface damage.
The spots are different.
Different spots have some common characteristics, but different types of spots have different performances. A correct understanding of these spots can help us to fight against various spots.
sunburn
The sunburn is about the size of a rice grain to a dime, dark brown with unclear edges. Generally concentrated in the long-term ultraviolet irradiation site.
freckle
Freckles are as big as the tip of a needle to a grain of rice, brown or light brown, and are usually common around the nose and cheeks.
chloasma
Chloasma is generally a patch with clear boundary and irregular shape, which is light brown or light brown and symmetrically distributed in the orbit, forehead, eyebrow arch, nose, cheeks and mouth.

The senile plaque is generally a large irregular, papillary raised plaque, which is brown or dark brown, and is common in the face, hands, limbs and other parts of the elderly.
sunburn
Traumatic black spots vary in shape and size, showing local light brown, dark brown or brown macula, and the growth site is not fixed.
Pictures of various types of spots 3 1, finch spots:
Most of them are hereditary, often appearing among brothers and sisters, but not at birth, until puberty and obvious, distributed on the face, all parts of the body are like millet granules, light brown and dark brown in color, round in shape, and most hands and feet also have them.
Congenital system, which is difficult in traditional treatment, can only be prevented from increasing or darkening. You can apply sunscreen cream or oil to avoid direct sunlight.
2. Water-deficient spots:
Long-term water deficiency or malnutrition of skin (improper maintenance) causes cells to be damaged or die due to lack of water or nutrition, and causes poor melanin metabolism, forming irregular spots of large and small, which are found by almost everyone, just in quantity.
If the person who usually takes less care of it will become mixed spots or dermal spots in about 3 years, and the person who takes more care of it for 5 years, all the water-deficient spots must be told that the sooner they are removed, the better. The color changes to tan-brown-dark brown.
3, senile plaque:
Floating on the surface, due to long-term loss of maintenance, skin aging or ovarian function damage. Uterine tumors of the eldest son can happen to everyone. There are two kinds: concave and uneven-slow repair; Slightly convex and uneven-repair faster.
4, sunburn:
Excessive sun exposure increases the melanin in the bottom layer of the skin and gradually accumulates on the surface of the skin. Most of them are flaky or blocky, and the color is yellow or brown. This kind of sunburn is relatively simple in treatment. If you often apply it with nutrition and moisture, it will slowly recover, so you should avoid exposure to the sun.
Eat more vegetables and fruits containing vitamin C, and drink more water to strengthen metabolism and make pigments fade.
5, pregnancy spots:
Generally, when you are pregnant for 2-3 months, this spot, also known as pregnancy spot, will disappear naturally after1-3 months after delivery, and sometimes a little will remain on your face and fail to disappear completely. At this time, you should massage, maintain and bleach your face for a long time, so that the pigment will gradually become lighter and disappear into the invisible.
6, black spots:
Commonly known as melanosis, most of them are caused by long-term use of inferior medicine cream that stimulates the poison of mercury and arsenic, or A acid, fruit acid (bad skin change) or betel nut leaves, especially perfume, blush, rouge, foundation and powder cake.
In recent years, the number of patients has gradually increased, so the competition in cosmetics business, regardless of the consequences, only for profit, some manufacturers add mercury toxins into cosmetics and creams, claiming that they can cure black spots, pimples, acne and bleaching, because mercury poison has sterilization and bleaching power.
But it can only bleach temporarily, which will destroy the red blood cells of the skin and make the fragile skin lead to dermatitis or melanosis. More seriously, the use of ointment containing mercury will enter the body through the pores of the skin and damage the function of the liver and kidney. The parts that occur are all on the forehead, cheekbones, behind the ears, cheeks and neck. The color is light brown and will gradually turn dark brown.
In addition to cosmetics, sometimes due to partial eclipse, excessive fatigue, lack of vitamin A and vitamins A, C, D, E, etc. If the color is brown and epidermal spots, melanin will penetrate deep into the dermis without timely treatment, and the color will deepen into black, which is dermal spots at this time.
7, blood spots:
As the name implies, the location of malar bone spots is mostly in the malar bone.
Some people's spots may also occur on both sides of the upper forehead, and its color is generally gray or brown or even blue-black. The skin pathological manifestations of zygomatic plaque are as follows: there are scattered melanocytes in the upper dermis.
Because of the re-refraction of melanin cells in the dermis when the sun shines, the cheekbone spots are gray-blue at first. Because zygomatic plaque is melanocyte hyperplasia in dermis, topical antiplaque drugs are ineffective for it.
8, liver spots:
Also known as chloasma, most patients are middle-aged women, especially after menopause, cheeks, forehead, eyes, nose wings, lips, chin and so on, are all light-leaking parts of the skin, especially cheeks, which will form left-right symmetry, with different appearance sizes and irregular shapes. The spots are mostly light brown or dark brown, and some of them cross the bridge of the nose like butterflies, so some people call them "butterfly spots".
The color depth of the stain can be divided into three levels:
The first clarity-the color of the stain is light, and the range is only on the cheeks. Most of them are epidermal spots;
In the second stage, the color of the spots is somewhat dark, covering cheeks and nose, and some of them have penetrated into the dermis, which is called mixed spots because of epidermis and dermis;
The third stage of pigmentation is dark brown, covering the upper forehead (middle), nose and cheeks, and most of them have become dermal spots.
Causes: Endocrine disorder, slow metabolism of liver, ovary, uterus, kidney and other functions are easy to produce liver spots.
The longer the time is delayed, the slower the treatment will be, and the medicinal bleaching cream should not be used, which contains mercury toxin, which will completely lose the keratin, make the skin white and weaken the resistance.
