Excess melanin synthesis is a common factor in the development of hyperpigmentation. Melanin is the pigment responsible for the colour of human skin. Melanocytes are the skin cells responsible for making it. Melanin production can be affected by many external causes and medical disorders.

Causes for Skin Darkening

Pigmentation changes, often known as hyperpigmentation or a darkening of the skin, can be caused by several different medical issues. The following are some of them:

• Hereditary factors: The altered skin tone and the appearance of patches may result from genetic variables present since birth.
• Skin disorders: The darkening of the skin, the development of scars, and the thickening of the skin can result from several skin problems.
• Vitamin deficiency: Darkening and roughening of the skin have been linked to insufficient intake of crucial vitamins such as vitamins A, E, C, and B complex. Skin becomes unattractive when you don’t get enough vitamins. Diseases of the liver can also cause hyperpigmentation. Darkening of the skin may be an indicator of liver dysfunction.
• Hormonal changes: Skin darkening may also occur due to hormonal changes in our bodies or pregnant women.
• Exposure to UV rays: Tanning can be caused by overexposure to the sun’s UV radiation. The excess melanin production is what makes the skin darker.

Always remember that skin darkening may indicate some medical illnesses, and seek professional medical advice before using any skin lightening treatments.
