The skin is dull and dull, especially with the increase of age, the situation is getting more and more serious, and a lot of whitening products are used, but the effect is lacking. In fact, when the skin is dark, the reason should be found. In order to prescribe the right medicine, the following six reasons to see if there is your cause, and promptly treat it.

1. Melanin overproduction

This kind of dullness can happen to anyone, especially those who don't like sunscreen and fair skin. Long-term exposure to ultraviolet light can easily cause damage to the stratum corneum of the skin, and the arrangement is disordered, resulting in a rough touch on the surface of the skin, and the face looks naturally dull.

The reason for testing your skin's dullness is not because of melanin, you can see if the skin color of your face is darker than the color of your arms and calves. If it is, it means that you may not be able to do enough sunscreen to stimulate the overproduction of melanin. In daily life, stick to sunscreen every day, and use tools such as sunhats and sunglasses.

2. Keratin oxidation

Long-term exposure in the air pollution environment such as ultraviolet rays, electromagnetic waves, computer screens, smoking, etc., it is easy to stimulate the body to produce excessive free radicals, causing aging of the stratum corneum, and the oxidation of the stratum corneum is also a major cause of the skin color is not shiny. . The oxidized skin's stratum corneum is injured and unevenly arranged, resulting in a rough touch on the skin surface, so the face looks dull.

In addition to the daily isolation and sun protection work, the skin should be supplemented with anti-oxidant substances. You can eat a lot of vitamin-rich products and use anti-wrinkle and anti-oxidation products.

3. Old waste horny accumulation

The old dead skin cells of the skin will not accumulate on the surface without normal metabolism. The accumulation of old dead skin cells will cause the skin to feel rough and make melanin difficult to metabolize. This type of skin may be accompanied by large pores and frequent oil secretion. If you do not properly remove the old dead skin cells, even if you wipe a lot of whitening skin care products, it is difficult to get into the skin to be absorbed.

Therefore, to solve this kind of problem is to use more products to remove aging keratin, but the use should not be too frequent, healthy skin is used twice a week, and sensitive skin can be used once a week, and the products used should be as gentle as possible.

4. Insufficient skin moisture retention

Aging, computer screen irradiation, air conditioning, etc. will bring dryness to the skin, while whitening is always carried out with moisturizing. The skin with sufficient moisture will be transparent and elastic, and the effect of whitening products will be better. In the case of skin that lacks moisture, the regulation function of the stratum corneum will decrease, the resistance to sunlight and pollution will be significantly reduced, and the deposition of dust on the face will bring dullness to the skin.

MMs that use whitening products have no effect. You can check if your water retention work is done. You can apply moisturizing mask before using whitening products or moisturize the skin with moisturizing essence before using whitening products. It is also a good choice to use some whitening products with complete water retention and whitening effect.

5. Blood oxygenation declines

This type of person is not black in color, and the skin is dull. It is not because melanin is causing trouble. It is because the oxygen content in the blood is too low. Under the illumination of light, the oxygen content of hemoglobin will also determine the skin color. When the blood contains high oxygen, the blood circulation is smooth, the skin tone will look rosy and shiny, and if the oxygen content is low, it will appear dark and sallow.

The cause of this poor skin tone may come from malnutrition and partial eclipse, which makes the body lack the nutrients needed for hematopoiesis such as iron, vitamin A, vitamin B, etc., so adjust the balanced nutrient intake, proper aerobic exercise, and use Promoting cell cycle activity and whitening skin care products can effectively change the dull skin condition.

6. The schedule is not normal

Abnormal work and rest can cause the body's metabolic capacity to decline, affect melanin production and metabolism, reduce the repair ability of the epidermis, and may also cause endocrine disorders, which in turn affect the skin texture.

Sleeping time in the evening is the moment of skin renewal and repair. The new cell growth and the elimination of aging keratinocytes occur in the “beauty sense” period. Too late to sleep or lack of sleep will make the metabolism function no longer smooth, causing aging keratin accumulation. Thickening, the skin naturally loses its sense of transparency, showing a dull grayish gray. In addition, if people with hormonal imbalance form liver spots often stay up late, the liver spots on the face will be aggravated. Therefore, if there are no MMs in the above five situations, the color is still dull, it is undoubted that there is a problem with your schedule.
