What causes melanin to form?

The formation of melanin will make our skin darker and dull, so we should pay attention to understand the reasons for the formation of melanin. Common visceral function factors or endocrine factors can lead to the formation of melanin.

1. Visceral Function Factors

Traditional Chinese medicine believes that the human body's internal organs directly affect the face.

(1) Lung: It is responsible for breathing and promoting the circulation of qi, and is responsible for the skin and fur. The appearance of spots is related to lung heat.

(2) Heart: It governs the blood vessels and mind, and its radiance is on the face and its fullness is in the blood vessels. Deficiency of heart qi, deficiency of heart yang, rising of heart fire, stasis of heart blood, insufficient heart blood, and heat entering the pericardium will lead to a dull complexion.

(3) Kidney: Kidney is the foundation of one’s innate constitution. The kidneys control essence, fluids, hair, bones and marrow. Deficiency of kidney yang and kidney essence leads to lack of energy and low temperament;

(4) Liver: It regulates the flow of blood and regulates the qi and blood. Insufficient liver blood, increased liver fire, abnormal function, inability to secrete hormones normally, and facial lesions may occur.

(5) Spleen: It controls muscles, limbs, food digestion, absorption and transportation of nutrients. If the spleen fails to function properly, the skin and face will become pale and dull, the face will become yellow and prematurely aged, and chloasma and dark circles will easily form.

2. Endocrine factors:

1. Endocrine disorders: As women of childbearing age age, their monthly menstruation leads to long-term loss of Qi and blood; the atmospheric environment changes unpredictably, and the heat, cold, wind and rheumatism can easily damage the kidneys; during childbirth, women do rough labor, worry, get angry and sad, which seriously damages their vitality; the circulation of Qi and blood between the twelve meridians is greatly affected. The face is where the twelve meridians converge. Due to weak vitality, facial cells cannot get proper nourishment, resulting in melanin deposition, leading to the formation of spots. When observing women over 30 years old, more than 80% of them are troubled by dark spots due to endocrine factors.

2. Pituitary gland: It is the main secretory gland. Instinctual desires are suppressed, causing autonomic nervous system disorders, which causes the pituitary gland to secrete melanin.

3. Thyroid: Excessive thyroid hormones lead to bad temper, mental tension, fatigue, insomnia, hyperthyroidism, and the production of more melanin.

4. Pineal gland: If you often lack sleep, the pineal gland cannot function normally and is prone to producing melanin.

5. Gynecological diseases: irregular delivery and abnormalities of the uterus and ovaries can cause estrogen imbalance and the production of melanin. Melanin and freckles appear during development due to genetic factors, and most of them are hereditary.

3. Drug factors:

1. Contraceptive pills: The main ingredients are estrogen and progesterone, which can easily promote the production and precipitation of melanin;

2. Excessive hormones in hormone ointments can easily stimulate the growth of melanocytes and produce brown spots;
