Seven reasons why your skin cannot be whitened

If you want to deal with a dull and bad complexion, you must first understand the causes of dull and sallow skin tone, and then you can start a plan to eliminate pornography, gangs, and dullness. Only by mastering the basic skills first can your whitening efforts be in vain.

1. Excessive production of melanin

This type of darkening cause is more common in people who neglect sun protection. You can check whether the skin color of your face is darker than that of your arms and calves. If so, it means that you may not do enough sun protection, allowing ultraviolet rays to stimulate excessive melanin production. Exposure to ultraviolet rays can easily damage the skin's stratum corneum and disrupt its arrangement, causing the skin surface to feel rough and the complexion to look naturally dull.

2. Oxidation of cuticle

Free radicals can cause skin aging, and the stratum corneum is no exception. Oxidation of the stratum corneum is a major reason why the skin looks dull. Common factors that cause stratum corneum oxidation include electromagnetic waves that are everywhere in life, long-term exposure to computer screens, smoking, exposure to air pollution, and lack of sleep, all of which will produce free radicals and cause stratum corneum aging. Exfoliation is especially important.

3. Accumulation of old dead skin cells

If the skin's old dead skin cells are not metabolized normally, they will accumulate on the surface. The accumulation of old dead skin cells will make the skin feel rough and make it difficult to metabolize melanin. This type of dull skin may be accompanied by enlarged pores and frequent oil secretion. If the old dead skin cells are not removed properly, no matter how many whitening skin care products are applied, it will be difficult for them to enter the skin and be absorbed.

4. Insufficient skin moisture retention

Aging and long-term exposure to computer screens can lead to dry skin. When the skin lacks moisture, the regulatory function of the stratum corneum will decrease, and the skin's resistance to sunlight and pollution will be significantly weakened. In addition, the static electricity from computer screens will produce a lot of tiny dust particles that are invisible to the eyes and deposit on the face, which is also the culprit for dullness.

5. Decreased blood oxygen content

People of this type do not have dark skin, and their dull skin is not caused by melanin, but rather by insufficient oxygen content in the hemoglobin in the capillaries. Under the irradiation of light, the oxygen content of hemoglobin will also determine the appearance of skin color. When the oxygen content in the blood is high and the blood circulation is smooth, the skin color will look rosy and shiny. Conversely, if the oxygen content is low, the skin color will look dull and sallow. Excessive liver fire or stagnation of liver qi can cause poor blood circulation, resulting in a decrease in the blood's ability to carry oxygen, which is also the cause of dull skin tone.

6. Abnormal work and rest

Abnormal work and rest schedules will cause the body's metabolic capacity to decline, affect the production and metabolism of melanin, reduce the repair ability of the epidermis, and may also cause endocrine disorders, thereby affecting skin quality.

The sleep time at night is the time for skin renewal and repair. New cell growth and elimination of old keratinocytes all occur during the beauty sleep period. Going to bed too late or not getting enough sleep will make the metabolic function no longer smooth, causing the old keratin to accumulate and thicken. The skin will naturally lose its transparency and appear dull and gray. In addition, people who develop liver spots due to hormonal imbalance will have their liver spots on their faces aggravated if they often stay up late.

7. Precipitation of colored substances

Another reason for a sallow complexion is the deposition of colored substances, which is common when eating too many carotenoid foods (such as carrots, papayas, oranges, tomatoes) causing temporary yellowing of the skin. However, women with this type of sallow complexion don't need to be too nervous. This temporary pigment deposition will be eliminated through the body's natural metabolism and the complexion will return to normal after they stop eating these foods for a few days.
