Skin Pigmentation Disorders: Melasma and Coloration of the Skin Causes

Skin Pigmentation Treatment Dr Khurram Mushir

Karachi: The color of the human skin is due to a brown pigment called melanin. Pigmentation or coloration of the skin is dependent on the amount of melanin present in the skin. People with pale skin produce very little melanin and people with darker skin produce higher amounts of melanin. Pregnancy and sun exposure can also make skin darker, while infections, burns, and blisters can make skin lighter.

Skin pigmentation disorders affect the color of the skin. In some cases, the cells that produce melanin – melanocytes – become damaged, thus affecting melanin production. Some disorders affect the entire body while others affect only patches of skin. In the following video skin specialist, Dr. Khuuram Mushir tells how to remove skin pigmentation and freckles.

Pigmentation Disorders:

Skin pigmentation disorders can be localized or widespread and the changes they cause to the skin are broadly classified as depigmentation, hypopigmentation, and hyperpigmentation.

Depigmentation is due to the loss of pigment, which makes the skin lose its natural color. Pigment loss can be partial or complete and temporary or permanent.

Hypopigmentation is caused by a very low amount of melanin being produced by the cells and it makes the skin lighter than normal. Apart from primary pigmentation disorders, hypopigmentation can also result from injuries to the skin such as burns, ulcers, chemical exposure, or skin infection.

Hyperpigmentation is a result of the production of very high amounts of melanin by the melanocytes, making the skin darker than normal. It can also be caused by other pigmented substances, drugs, or sunlight exposure.

Skin Conditions Related to Pigment Disorders

Some major skin diseases caused by pigment disorders are:

Melasma – is characterized by symmetric, dark brown patches of melanin on the face. Hormones and oral contraceptive pills are the main causes of this disorder. Melasma occurring during pregnancy is called the mask of pregnancy.

Incontinentia pigmentation – is an inherited skin pigmentation disorder associated with abnormalities of the skeletal system, teeth, central nervous system, and eyes. It is caused by a mutation to a gene that belongs to a group of genes causing neurocutaneous disorders. This condition is more common in males than females and causes discoloration of the skin due to excessive melanin deposits.

Vitiligo – is a disorder causing smooth, white patches in the skin and is a result of the loss of melanocytes. The white patches are highly sensitive to sunlight exposure. chaiyon ka desi ilaj in urdu, chaiyon ka desi totka, chehre ki chaiyan door karne ka tarika.
