[Some people’s faces are small biscuits, others are a pancake, while Sister Wang’s face is covered with sesame seeds on the pancake! ]
Lao Wang and pawn next door.
The inexplicable spots on her face are believed to be the distress of many women who love beauty. Because of the long spots, Sister Wang, who did not dare to eat sesame seeds again, suffered even more.
Today, Dr. Clove invited a professional doctor to tell everyone about the spots on his face.
Spot, how did you come from?
Our skin consists of two parts: the epidermis and the dermis. As the name implies, the epidermis is located in the outermost layer and plays a protective role. There is a cell called melanocyte in the epidermis. Its function is to produce pigment particles and protect the epidermal cells from ultraviolet rays.
There are no more than two possibilities for common color spots:
- One is the activity or proliferation of epidermal melanocytes, which increases melanosomes in the epidermis, thus blackening the skin. The other is that melanocytes fall into the dermis to form pigmophilic cells due to the destruction of the basal layer of the epidermis, thus blackening the skin.
Freckles: Partial heredity, partial sun exposure
Freckle is a kind of brown punctate pigmentation spot that is easy to occur on the face, and the area of the spot is generally relatively small.
Freckles mostly begin to appear in childhood, indicating that they have genetic tendency and are related to genes. Fortunately, the incidence rate of freckles is not the highest in our yellow race, but the highest in Caucasians.
From the disease site, freckles are especially easy to receive sunlight in the nose and cheeks. Therefore, it is related to sunlight, which also indicates that freckles are seasonal. In summer, when sunlight is strong, rash increases, increases, and color increases. In winter, ultraviolet intensity weakens, and rash becomes lighter and smaller.
Special attention should be paid to sun protection to prevent freckles.
Chloasma: Various causes may cause
Chloasma is often manifested as light brown to dark brown or grayish brown patches on the side of forehead, cheek, nose and upper lip, with irregular boundaries.
Although it is also a spot, the onset characteristics of chloasma are just opposite to freckles. It is more common in China, especially in middle-aged women.
Because although the specific pathogenesis is unclear, the common aggravating factors include pregnancy, drugs and sunlight, which can be presumed to be a hormone-related disease.
Therefore, in addition to sun protection, special attention should be paid to the use of drugs, especially contraceptives, to prevent chloasma.
Post-inflammatory pigmentation: black pockmarks, allergy, trauma
Pigmentation after inflammation Many diseases that may leave color spots on the face include common acne (acne), facial contact dermatitis, trauma and other skin diseases that can cause inflammation.
For example, many people can’t help squeezing acne because they can’t control their hands, which will cause secondary pigmentation. After the acne disappeared, a black mark was left on the face.
Therefore, once there is inflammation on the face, whether it is acne, allergy or trauma, it is necessary to seek medical treatment in time and control the inflammation quickly, so as to minimize the occurrence of color sink after inflammation.
Face has spot, how to deal with
If there are already color spots on the face, the treatment method is nothing more than to eliminate them one by one according to the principle of color spots generation.
In the first case, melanocytes are active and produce more melanosomes, so substances that inhibit the production of melanosomes can achieve the purpose of lightening spots.
In the second case, the pigment particles are in the dermis, which requires the garbage cleaner to clean them bit by bit. At this time, except for the prevention of inflammatory drugs, the freckle removal effect of other drugs is relatively limited.
Is the freckle removal effect of skin care products good?
Skin care products remove freckle, mainly aiming at the active melanin in the epidermis.
Some skin care products contain substances that inhibit melanin production, such as kojic acid, arbutin, hydroquinone or vitamin C.
Skin care products containing tartaric acid or salicylic acid can lightly peel off the epidermis so as to promote the metabolism of the epidermis and achieve the purpose of removing freckles. However, these skin care products have certain irritation. The higher the concentration, the better the effect, but the worse the safety.
Therefore, when choosing this kind of skin care products, it is best to consult a doctor.
Can I use topical drugs?
The use of external drugs for color spots is nothing more than through the following three aspects:
-
Inhibiting Tyrosinase Activity and Reducing Melanosomes Synthesis;
-
Promote the metabolism of epidermis;
-
Inhibit dermal inflammation.
For freckle-removing drugs, they must be carried out under the guidance of doctors. Because drugs are not used well, white spots may occur, which are much more difficult to repair than black spots.
What are the options for medical beauty freckle removal?
In addition to external drugs, another artifact of dermatologists is laser.
Because the laser energy is relatively large, the advantages are: fast, accurate and ruthless.
However, medical beauty freckle removal is not as simple as picking up a machine. If the pigment is on the epidermis, the energy may also irritate melanocytes while causing melanoma particles to explode, which is the problem that sometimes worsens after chloasma is treated with laser.
Therefore, if you want to use laser freckle removal, you also need to judge the type of freckle first under the guidance of doctors, and then select appropriate machines and parameters. First ensure safety, then achieve the effect.
No matter whether there are spots or not, sun protection must be done well.
In addition, if you want to remove spots on your face, you’d better not use skin care products or drugs indiscriminately.
With the help of professional dermatologists, we should first identify which type of spots we have, and then choose targeted prevention and freckle removal methods. Only in this way can we get twice the result with half the effort and effectively remove freckle.
