Skin whitening secrets What causes your skin to become darker?

As the saying goes, "a white complexion hides three uglinesses", whitening is a topic in almost every woman's life. Dark, rough and dull skin will not be able to evoke beautiful vitality no matter how beautiful your facial features are. What causes your skin to become darker?

UV rays

1. Ultraviolet rays promote melanin. Everyone should be familiar with the term melanin. Excessive production of melanin in the skin is a major killer that makes it difficult to whiten the skin, and the biggest reason for the massive production of melanin is ultraviolet rays.

If people with fair skin do not pay attention to sun protection and expose their skin to ultraviolet rays for a long time, melanin will form in the skin. After precipitation, it may cause dullness and spots, and the skin tone will not be white.

Therefore, we must do a good job of sun protection in our daily life. Whether it is cloudy or sunny, we must apply sunscreen to our skin to prevent the formation of melanin.

2. Lack of moisture in the skin

Computer radiation, air conditioning and skin aging in daily life can cause dryness of the skin, leading to a decline in skin quality and resulting in dull skin.

Skin whitening and moisturizing have always been closely linked. Only hydrated skin can show a whiter and more radiant complexion. Skin that lacks water has poor metabolic capacity, which reduces the skin's repair function and causes dark skin.

3. Disordered work and rest

Irregular living habits are not only bad for your health, but will also make your skin darker! During sleep at night, the skin is in the best state for repair. Only by ensuring good sleep can the skin metabolism be smoother and the skin be whiter. Poor rest and insufficient sleep not only affect your health, but also slow down blood flow to the skin, cause blood vessel constriction, cause blood stasis into spots, and turn the skin gray and black. Lack of sleep will affect the skin's moisture-locking function, causing the skin to become severely dehydrated. At the same time, due to the inability to guarantee the supply of oxygen, the skin will be malnourished, leading to local pigment accumulation, dryness, darkening, etc.
