The formation of spots is actually inseparable from them

What female friends worry about most is spots on the face, which greatly affects the appearance and youth is gone forever. In fact, there are reasons for the formation of spots. The most common ones are ultraviolet radiation, bad cleaning habits, genetic factors, etc. If you want to stay away from them, you must first curb these causes.

1. Reasons

1. Ultraviolet rays

When exposed to ultraviolet rays, the human body will produce a lot of melanin in the basal layer in order to protect the skin, so more pigment will accumulate in sensitive areas to protect the skin. Frequent exposure to strong sunlight not only promotes skin aging, but also causes skin diseases such as dark spots and freckles due to pigmentation.

2. Bad cleaning habits

The skin becomes sensitive due to strong cleansing habits. This can irritate your skin. When the skin is sensitive, the body's melanocytes will secrete a lot of melanin in order to protect the skin. When the pigment is excessive, skin pigmentation problems such as spots and blemishes will appear.

3. Genetic factors

If one of the parents has spots, the probability of the child having spots is very high. This situation can be determined to be the result of genetic genes to a certain extent. Therefore, those who have freckles at home, especially the elders, should pay attention to avoid ultraviolet radiation, which is one of the important factors causing freckles. This is something you must pay attention to in order to prevent spots, and you should also use more whitening skin care products that are suitable for your skin type.

2. Classification of spots

1. Active spots: Due to the active acylamino acid enzyme, the nature is unstable. Affected by external light and endocrine factors, the color depth will change and can be removed. Common ones include: chloasma, sun spots, pregnancy spots, and dark spots.

2. Qualitative spots: They are stable in nature and are not affected by external factors and will not change. Once the original part is removed, it will not grow back. Common ones include: genetic spots, freckles, age spots, and pigmented moles.

Pigmentation characteristics:

1. Freckles: related to genetics. 3% are related to autosomes and blood. The color deepens after sun exposure and the spots are distributed in isolated spots with a diameter not exceeding 0.5 cm. They are often distributed on the cheeks, hands, and shoulders. They begin to appear at the age of 5-7 and are a type of spot that is difficult to remove.

2. Chloasma: also known as butterfly spots and liver spots. It is light brown and flaky in shape. The patches vary in size, have clear borders, open and close irregularly, and do not protrude above the skin. They are commonly seen on the face. Symmetrical on the cheeks. The main reason is related to endocrine and female hormone imbalance.

3. Pregnancy and sunburn: acquired factors, caused by ultraviolet rays, irregular in size

4. Black spots. It is more obvious in people with thinner and drier skin. The main reason is that they neglect maintenance and do not do a good job of sun protection. This makes it easier for melanin to float to the surface of the skin. It is the most common skin problem in middle-aged women (men can also develop dark spots). Usually a whole brown spot appears on the cheeks, forehead, upper lip and lower chin. Because of its color, it is also commonly known as liver spots. Causes and aggravating factors include pregnancy, oral contraceptives, certain medications (such as anti-epileptic drugs), and sun exposure.
