7 Reasons for Dark Yellow Complexion in Summer

Beauty and Whitening 7 Reasons Why Your Complexion Is Dark and Yellow in Summer. If you want to deal with a dull and bad complexion, you must first understand the causes of dull and yellow skin tone. Only by mastering the basic skills can you avoid wasting your beauty and whitening efforts. In the summer, you need to strengthen your beauty and whitening efforts. The melanin content, hemoglobin content, thickness of the stratum corneum, neatness of stacking and arrangement, water content of the stratum corneum and other factors in the skin are all related to the skin color. The following explains these factors that affect the beauty and whitening effects and the reasons why your skin color is dark yellow.

1. Excessive production of melanin:

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 cutin:

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.

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 cause the skin to feel rough and make it difficult to metabolize melanin.

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.

5. Decreased oxygen content in the blood:

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.

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.

7. Precipitation of colored substances:

This is common in people who eat too much carotenoid foods (such as carrots, papayas, oranges, tomatoes) and cause temporary yellowing of the skin. However, this type of "yellow-faced woman" does not need to be too nervous. This temporary pigmentation will be eliminated through the body's natural metabolism and the complexion will return to normal after a few days of stopping eating.

The sleep time at night is the time for skin renewal and repair. New cell growth and elimination of aging 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 accumulation and thickening of aging keratin. The skin will naturally lose its transparency and appear dull and gray, affecting the effect of beauty and whitening. In addition, people who develop liver spots due to hormonal imbalance and often stay up late will have their liver spots on their faces aggravated, which is also the reason for their dark yellow skin tone.
