The introduction of various spots, in life, I believe many friends are worried about the spots on their faces. There are many kinds of spots, not only chloasma and pregnancy spots, but also butterfly spots and freckles. Below I have sorted out the introduction of various spots.
Introduction of all kinds of spots 1 classification of long spots, freckle removal methods and prevention methods.
1, chloasma
Chloasma is a kind of facial melanism, which is a pigmentation spot appearing on the face. Chloasma is mostly caused by female stress and endocrine disorders.
2. Black spots
This kind of spots mostly appear on both sides of cheeks, mostly due to long-term ultraviolet radiation, or long-term acne to stimulate the skin, produce melanin, accumulate precipitation, and finally form black spots.
3. Sunburn
Sunburn is mostly caused by skin exposure, edema or erythema. After that, there will be powdery desquamation and skin pigmentation.
4, pregnancy spots
Women will appear during pregnancy, but will fade after delivery. When many women have pregnancy spots, they may also have dark spots, which are easy to be confused.
5, dark brown spots
This kind of spots generally occur around the face, mouth and eyes, and middle-aged women will have more such spots. When you are overtired or have menstrual cramps, the color of chloasma will deepen.
6. Melanin
Some women are born with melanin, which is a congenital melanocytic nevus. This kind of melanin is mostly produced by melanocytes in the basal cell layer between the skin surface layer and the dermis layer.
7.freckles
Freckles are mostly genetic. In addition, sun exposure can also lead to the formation of freckles. Women with white skin are particularly prone to freckles. If you don't do a good job of sun protection in summer, freckles will increase and the color will deepen.
8. senile plaque
Generally speaking, people who get more sunshine tend to grow taller. In addition to the face, the back and scalp will grow.
Many people may be worried about the stain on their faces, but they can't tell exactly what kind of stain it is. Most of the spots have pigmentation on the skin, and the color is obviously darker than the surrounding area. Some people are caused by congenital factors, and some are also caused by acquired. Understand the eight categories of stains and take preventive measures in advance to avoid more stains.
Introduction of various spots 2 1, chloasma commonly known as "butterfly spot"
"Liver spots" or "pregnancy spots" are mostly found in middle-aged women, especially after menopause, around cheeks, forehead, eyes, nose, lips and chin. , are the light leakage parts of the skin, especially the cheeks, which will form left-right symmetry, uneven appearance and irregular shape. Spots are mostly light brown or dark brown, and some cross the bridge of the nose like butterflies, so some people call them "butterflies"
2, freckles
It is a common brown punctate pigmentation spot on the face, and it is an autosomal dominant hereditary skin disease. Pigment spots are often punctate, round, oval or various irregular shapes, which are more common around the face, especially around the nose and cheeks. Skin lesions are called freckles because they look like spots on birds' pecks or eggs.
3, coffee spots
It is a common pigmented dermatosis, and 10% ~ 20% of normal people can see a single coffee spot. The color of coffee spots ranges from light brown, brown to dark brown, and the size ranges from a few millimeters to dozens of centimeters, with clear boundaries;
The surface skin texture is completely normal and there are no conscious symptoms. It is more common that the trunk will not disappear naturally, and laser treatment is effective. However, if it shows multiple coffee spots, it usually suggests multiple system damage, especially the skin manifestations of neurofibromatosis.
4. Sunburn
The reason is overexposure of sunlight and ultraviolet rays, and other rays, such as screen rays, can also cause sunburn. The melanin pigment in the bottom layer of the skin increases and gradually accumulates on the surface layer of the skin. Most of them are flaky or blocky and yellow or brown in color.
5, senile plaque (seborrheic keratosis)
Also known as basal cell papilloma or senile wart, it is a very common benign tumor of skin epidermis. Usually there are many light brown to black warty lesions on the surface, and the scales are greasy, which most often occur in middle-aged people, especially in the face, neck, chest, back and back of the hand of the elderly, but not in the palm.
6. Freckle moles are also called sunspots.
Refers to the brown or black spots on the skin or mucous membrane, which can occur in any part of the skin, or at the junction of skin and mucous membrane or conjunctiva. The disease is common, with brown or dark brown spots of the same color, rice grains as big as peas, clear boundaries, smooth surface or slight desquamation;
Scattered, single or multiple, but not fused, can be limited to a certain part, but also throughout the body. This disease generally does not need treatment, and has no impact on health, but it has an impact on beauty. The etiology of the disease is not clear, and it may be related to ultraviolet radiation or heredity.
Introduction to various spots 3 1, senile spots
Senile spot, also known as seborrheic keratosis in medicine, is a common benign skin tumor in clinic, which is more common in the elderly. Often appear in exposed parts, such as face, forehead, back, neck, chest and so on. Sometimes it can also appear in upper limbs and other parts.
It is characterized by round, oval or irregular brown spots with clear boundaries, consistent colors and occasional itching. It may be related to repeated sun exposure, age, virus infection and genetic factors.
2, chloasma
Chloasma, commonly known as "butterfly spot", "liver spot" or "pregnancy spot", mainly occurs on the face, mainly in the cheekbones, cheeks, nose, forehead and chin. Brown or black patches with unclear boundaries, mostly symmetrical butterflies.
Winter is lighter than summer, or changes with sun exposure, mental state, sleep and other factors. It is generally believed that it is related to pregnancy, ultraviolet radiation, hormone level and genetic factors. It is common in young and middle-aged women and affects their appearance.
3, freckles
Freckle refers to the brown spots that mainly occur on the cheeks, which are characterized by multiple brown or brown rice grains, the number of which is uncertain, isolated and unconformity, and generally distributed symmetrically. More common in women, common in cheeks and nasal back, but also in exposed parts such as neck, shoulders, back of hand, forearm and chest back.
The disease belongs to autosomal dominant inheritance, and patients often have a family history. Winter is light and summer is heavy, and it gets worse after sun exposure. A large area of freckles affects the appearance very much, which is the hate of beauty.
4, coffee spots
Coffee spots, also known as coffee milk spots, are generally light brown spots that can be found at birth, ranging in color from light brown to dark brown, ranging in size from a few millimeters to dozens of centimeters, with clear boundaries, completely normal skin texture, scattered distribution, single or multiple, and can be seen in any part. This disease is hereditary skin disease and has nothing to do with sun exposure.
5. Sunburn
Sunburn is an acute inflammatory reaction caused by excessive exposure to strong sunlight. More common in spring and summer, erythema and edema appear in the exposed parts of the skin, and the erythema gradually turns dark red or reddish brown. In severe cases, blisters and blisters appear, accompanied by itching, burning or tingling. Mild erythema gradually subsided in 1-2 days, leaving desquamation and brown pigmentation. In severe cases, the blisters burst and eroded, and recovered about 1 week.
Laser treatment of these superficial pigmented diseases is fast and effective. After treatment, we need to go through the process of pigment regression. Therefore, sun protection during recovery period is very important. If you don't do a good job of sun protection, your skin will easily grow spots. Whether you do freckle or not, you should pay attention to sun protection. Laser freckle is a minimally invasive treatment, so you must go to a regular hospital to find a professional doctor for treatment. I hope everyone can get rid of the troubles caused by freckle!
