Third, if it is still not white, there may be the following reasons:
Cause 1: Excessive production of melanin
People who don’t like sunscreen and people with fair skin will be exposed to UV rays for a long time, which can easily damage the stratum corneum of the skin, resulting in uneven arrangement of the stratum corneum of the skin, resulting in a rough skin surface and dull complexion.
Cause 2, Keratin Oxidation
Long-term exposure to ultraviolet rays, electromagnetic waves, computer screens, smoking and other air pollution environments can easily stimulate the production of excessive free radicals in the body, leading to the aging of the stratum corneum, and oxidation of the stratum corneum will also make the skin look dull and dull. .
Cause 3, Aged keratin accumulation
Dead keratin from old skin accumulates on the surface without normal metabolism, causing the skin to feel rough and making it difficult for melanin to metabolize. This type of skin dullness may be accompanied by enlarged pores and frequent oil secretion. If you don't remove the old dead skin cells properly, no matter how much whitening skin care products are rubbed, it will be difficult for them to enter the skin and be absorbed.
Reason 4. Insufficient skin moisturizing ability
Whitening always goes hand in hand with moisturizing. Well-hydrated skin will appear transparent and elastic, and the effect of whitening products will be better. For skin that lacks moisture, the regulating function of the stratum corneum will decline, and the resistance to sun exposure and pollution will be significantly weakened, resulting in dull skin.
Cause 5. Decreased blood oxygen content
When the oxygen level in the blood is low, it appears dull. The reason for this poor complexion may be malnutrition and partial eclipse, which make the human body lack the nutrients needed for hematopoiesis. Therefore, it is important to adjust a balanced nutritional intake, appropriate aerobic exercise, and use active whitening skin care products that can promote cell circulation. Can effectively correct dull skin tone.
Cause 6: Irregular work and rest
Irregular work and rest will lead to a decline in the body's metabolic ability, affect the production and metabolism of melanin, reduce the repair ability of the epidermis, and may also cause endocrine disorders, thereby affecting the quality of the skin. Sleep time at night is the time for skin renewal and repair. Both the growth of new cells and the elimination of aged keratinocytes occur during "cosmetic sleep". Sleeping too late or not getting enough sleep can make the metabolism function less smoothly, resulting in the accumulation of aging keratinocytes. When thickened, the skin naturally loses its translucency and takes on a dull gray appearance.
