Where do human freckles come from? What are freckles? Why do some people have freckles on their face

Medical proof: "Plaques on the face, stasis in the body, there must be stasis if there are spots, and the treatment of spots does not separate from the blood." "The endocrine condition of the human body directly determines the cause of the formation of pigmentation, when the human body undergoes systemic pathological changes (that is, endocrine disorders), it leads to the poor flow of qi and blood in the human body, the meridians are blocked, resulting in internal stasis and internal stagnation, and the heart and blood can not reach the face and nourish the skin, and the melanin in the human body can not be discharged with the normal metabolism of the human body, and for a long time, it will form pigmentation.

The pigmentation is mostly manifested as **yellow as earth-colored, **itchy; In severe cases, it produces yellow-brown, menstrual disorders, insomnia and other diseases until it affects normal work. "Pigmentation" not only brings mental pain to the patient, but also causes heavy mental pressure. Some young men and women have lost the right to fall in love and marry because of the disease.

Husbands and wives turn against each other. Others are discouraged by the ineffectiveness of the treatment. There are tens of millions of patients in China.

In addition, sun exposure and long-term use of cosmetics containing lead, mercury, and hormone chemicals can also cause dark spots. Melasma is the in-depth development of pigmentation, patients with severe melasma, the face is very ugly, dark and ugly, and there will be irritability, depressed mood, irregular menstruation, insomnia, dreams, dry stools and other symptoms. Freckles are a type of lesion that occurs on the face in the form of spots, or small sesame brown or light brown spots.

The best areas of hair are the cheeks and the bridge of the nose, but it can also spread to the entire face or even the neck, which is one of the most common causes of facial beauty. Most of them are acquired, but some patients are congenital. However, whether it is congenital or acquired, it is closely related to genetic factors.

That is to say, patients with freckles have a certain quality, and people with this quality will develop freckles under the action of some external factors (such as sun exposure, **dryness, etc.). These phenomena are believed to be caused by endocrine disorders, also known as sub-health conditions. Although there are no organic lesions, people who are in this state for a long time will have a negative impact on work, study and life, and even lead to family crises.

Studies have proved that more than 80% of patients with spots, especially women after the age of 30, have slow skin metabolism, poor blood microcirculation, aging and rough cortex, dark and dull complexion, resulting in an increase in the number of pigmentation. Oh.

There are two main kinds of freckles in the human body, one is the melanin deposition produced by the interaction between the genes inherited by the human beings from their parents** and the environment, resulting in the production of freckles black brown or reddish-black half points called freckles, and there are also the individual itself in the growth and development of environmental factors caused, such as long-term exposure to ultraviolet rays, long-term irregular life, or exposure to some substances that secrete special stimulation of pigment production, in short, it is an adaptation and appearance of the individual in the living environment, It's a bit aesthetic, but it's not a good idea to overdo too many medications** or some other forms of diagnosis because it's natural, so try not to pay too much attention to it!

Freckles is a fairly common disease, mostly on the face, neck, back of hands, etc., with brown or black spots. Although freckles are not painful or itchy, they affect people's physical beauty, so they often cause troubles among teenagers, especially young girls. So many people want to be able to remove or reduce it.

Sun exposure is an important factor in the onset and aggravation of freckles, so it is important to protect against it. Especially in spring and summer, you should try to avoid exposure to the sun. Pay attention to the use of shading protection when you go out, and when possible, you can cooperate with external anti-sunscreen, because the anti-lightscreen has the ability to absorb ultraviolet rays or reflect ultraviolet rays back, such as zinc oxide cream, teach you a freckle removal trick:

Peach blossom melon seed honey: use peach blossom shade dry grinding, winter melon seed grinding, mix an appropriate amount of honey in equal parts, apply to the face, and apply to the affected area every night before going to bed. Black moles are applied to them.

Efficacy: Cleanse the face and remove spots. Suitable for moles, dark spots, freckles. Coriander soup:

Decoction with coriander, wash your face every day, effective for a long time. Efficacy: Remove dark spots and freckles. Vinegar water:

If you have freckles on your face, you can add a spoonful of vinegar to the water when washing your face, which has the effect of reducing pigmentation. Eggplant juice: eggplant, sliced and juiced, rubbed locally, days, ten days to see the effect.

Winter melon juice: Appropriate amount of winter melon pulp, mash to extract the juice, apply to the affected area, several times a day, use continuously, ** until then. Cucumber; Take cucumber to cut off the face, rub the face in the morning and evening, and rub it for a long time, which can not only eliminate freckles, but also make the face delicate and white.

Cherry juice: an appropriate amount of fresh cherries, apply the juice to the affected area, once a day, and have the effect of eliminating freckles.

Freckles are a kind of disease that we occasionally see in our lives, most of them appear on the face, and the appearance of freckles is mainly related to genetics, sun exposure, emotions, irregular life, and not loving to be clean.

Freckles is a ** disease, generally 3-5mm light brown or dark brown pinhead size to mung bean size spots, most of which appear on the face. In general, women are more likely to suffer from freckles.

The causes of freckles are summarized and roughly divided into genetics, sun exposure, emotions, irregular life, and not liking cleanliness.

Hereditary freckles: Generally, some people in the family have freckles, so the probability of children having freckles is relatively large, which belongs to hereditary freckles, sun freckles: because ** is exposed to ultraviolet rays in the sun to produce melanin particles, freckles are formed after a long time, so go out to prepare for sun protection.

Endocrine disorder freckles: Mood swings and irregular life are both causes of endocrine disorders, and endocrine disorders can also cause spots on the face, which usually occur in women between the ages of 30 and 40.

Freckles caused by unhygiene: If you do not pay attention to hygiene in your daily life, you will accumulate dust and makeup residues on your face for a long time, and freckles will form over time.

When you have freckles, you should first go to the hospital** department to let the doctor see the severity of your freckles, how to **, and judge the cause of your disease.

Then it's about relaxing your mind. Although freckles will have a certain impact on your appearance, you must not have a psychological burden, or even negative misanthropy. Because the more negative you are, the greater the impact on your mood and may aggravate the scope of your freckles.

Freckles is a relatively common disease, and the cause of the disease should be determined after the disease, and then the symptoms should be treated. In addition, the most important thing is to adjust your mentality and treat freckles positively and healthily.

Freckles are a physiological phenomenon caused by dominant inheritance. The reason why some people have freckles on their faces is because some people have this phenomenon through genetics as well as melanin precipitation.

It is caused by the hyperpigmentation, which is caused by the deposition of pigmentation and then the formation of different spots on the face.

Freckles are a problem caused by pigmentation on the face. Freckles seriously affect the appearance. Freckles form due to poor cleaning habits. It's more cumbersome.

Freckles are yellow-brown punctate pigmented spots on the face**, which are inherited in an autosomal dominant manner. Sun exposure can induce and exacerbate skin lesions.

**: Genetic predisposition, autosomal dominant. Sun exposure is a necessary factor for the development of rashes.

Clinical manifestations: skin lesions appear mostly around the age of 3 to 5 years, and more often in women. Their number increases with age. It is more likely to occur on the face, especially the nose and cheeks, and can affect exposed areas such as the neck, shoulders, and back of hands, and there is no rash on unexposed areas.

Lesions range from light brown or dark brown pinhead size to large mung bean macules, round, oval, or irregular. Scattered or clustered, isolated and not fused. No symptoms.

The rash darkens and increases in number after sun exposure in summer, and decreases or disappears in winter. There is often a family history.

Diagnosis: the number of melanocytes in the epidermis does not increase at the freckles, but the number of melanosomes increases markedly and is rod-shaped.

Freckles, a small yellow-brown or brown and pigmented spot common on the face, are autosomal dominant disorders in which the development of lesions is associated with sun exposure.

Freckles usually begin at the age of 4-5 years, and women are the majority. It gradually increases with age, most pronounced during puberty, after which it generally does not increase and gradually decreases in old age. It is more common in exposed areas, such as the forehead, cheeks, and jaw, and is more common on the bridge of the nose and under the eyelids, and in severe cases, it can affect the neck, forearms, and back of the hands.

Typical lesions are pale brown to yellowish brown needle-point-to-rice-sized round or round-like spots, isolated but not confluent, numbered, densely scattered, and symmetrically distributed. In summer, the number of spots increased and the color deepened; And winter is the opposite.

Laser freckles is the use of light radiation to produce the thermal, mechanical, actinic and electric effects of the principle of cautery, carbonization, gasification, coagulation and other means to act on the relevant diseased tissues, so that the biological tissue enzymes are inactivated, protein denatured, the damaged target tissue is removed, and the effect of laser freckles removal is achieved.

It used to be a headache for me, I should pay attention to avoid sun exposure and eating habits, and the usual basic care must be done well, and it will be better with the grape seeds of Huaqingyi, and the white and clean skin is not far away. But be sure to keep at it!!

1. What are freckles?

Freckles are brown punctate pigmented spots commonly found on the face that can be aggravated and precipitated by sun exposure.

2. Are freckles hereditary?

Freckles have a certain genetic predisposition and is a polygenic disease, but some families are autosomal dominant. There are some syndromes with freckles that can be autosomal dominant or autosomal recessive.

3. What are the manifestations of freckles?

Most of the patients are female, and most of them develop at an early age, and they tend to occur on the face, especially the nose and cheeks. Lesions range from pinhead to rice grains large, light brown to black-brown punctate spots of varying size and number. No symptoms. In general, spring and summer are heavier than autumn and winter.

4. Why should we pay more attention to sun protection if we have freckles?

This is due to the fact that the melanosomes in the epidermis quickly become oxidized after exposure to sunlight, X-rays, and ultraviolet rays, causing the rash to deepen, enlarge, and multiply. For example, the incidence and severity of freckles are significantly higher in areas with high altitude and high sun exposure than in areas with less sun exposure.

Freckles refer to brown spots as large as the tip of a pin, which is manifested in exposed areas, especially on the face, usually with tretinoins**, lasers can also **, but easily**, usually pay attention to avoid light. Freckles is a genetically related disease that manifests itself as brown spots on exposed areas, especially on the face, with pinpoints as large as grains of rice. In terms of **, it is usually possible to consider using retinoids, hydroquinone cream and other externally coated drugs**, and laser can also be **, but it will be often**, to be frequent**, ** the number of times is relatively large, the laser may be damaged**, and most doctors do not advocate the use of laser**.

In life, we should pay attention to avoiding light as much as possible and less sunlight, as sun exposure will aggravate freckles.

Freckles is a disease caused by hereditary factors, which is more common in adolescence, and is symmetrically and diffusely distributed on both sides of the cheeks or at the base of the nose bridge, and is generally a sesame grain size with well-defined spots.

Genetic factors: Generally speaking, freckles mostly appear on the whiter face.

Sun exposure: freckles are formed due to the precipitation of melanin in the body, when the blood is irradiated by ultraviolet rays, it will be acidic, and produce acidifying enzymes (tyrosinase), so that the melanin stored in the surface cells begins to act, floating on the surface, helping to prevent the body from absorbing excessive ultraviolet rays to resist external heat and form freckles.

Endocrine causes:

Endocrine disorders are also an important factor in the formation of freckles in women, and changes in the level of sex hormones in the body during menstruation or pregnancy will affect the formation of freckles. In addition, endocrine disorders can also lead to emotional instability, which indirectly causes the formation of freckles.

Lifestyle habits: The formation of freckles is inextricably linked to lifestyle habits. Bad habits such as stress, picky eating, and lack of sleep can all lead to an increase in melanin, which in turn leads to the appearance of freckles.

Therefore, people with unstable sleep time have a poor metabolic rate, which also leads to the appearance of freckles.

There are certain melanocytes scattered in the basal layer of human beings, and melanocytes continue to produce melanin, which plays a role in resisting the damage of various rays (mainly ultraviolet rays) in the universe to the human body. Due to the difference in the amount of melanin contained in **, there are blacks, yellows, and whites. Freckles are formed by melanocytes that have been genetically mutated.

The mutated melanocytes are larger than the normal melanocytes, and the dendritic processes are increased and enlarged. The dendritic process is full of melanin, revealing black spots one by one on the surface. The mutated melanocytes resemble the mother of a sea anemone, and the dendritic protrusions resemble the many antennae of the anemone.

Laser, freezing, grinding and other physical freckle removal methods want to destroy the subcutaneous structure of freckles through mechanical action to achieve the goal, but melanocytes are scattered in the basal layer, if the damage is too deep, reaching and beyond the basal layer, the injured part will not be repaired normally, and a scar will be formed. Therefore, these physical methods only dare to injure the epidermis above the basal layer, that is, only to destroy the branches and windows, or only to stab the melanocytes. It's like cutting off part of the anemone's antennae, or stabbing only the mother anemone, but the anemone will quickly repair the wound and grow new tentacles.

In the case of freckles, the mutated melanocytes grow new dendrites, which are filled with melanin. The freckles are revealed again on the **. The principle of cosmetic freckle removal is to use hydroquinone and hydroquinone derivatives to prevent amino acid from converting black cells to produce melanin.

However, due to the fact that the pathological structure and causes of freckles are different from those of other pigmentations, many cosmetics that have obvious effects on pigmentation have little effect on freckles.
