Skin Pigmentation Disorder: Their Types, Causes & Home Remedies

skin pigmentation

Pigmentation is a disorder of skin complexion and color. It results mainly due to the malfunctioning of the endocrine glands and the liver. The genetic background of a person also can influence pigmentation disorder.

This problem occurs as either an excessive coloration or darkening of the skin, or a loss of color and the pigment in the skin, over the entire body or just in patches & spots.

Skin color is determined by the amount of melanin in the skin. Fair-skinned people produce very little melanin, darker-skinned people produce moderate amounts, and very dark-skinned people produce the most.

Melanin is fairly evenly distributed in the skin, but sometimes people have spots or patches of skin with more melanin. Examples of such spots include freckles, age spots (lenities), and Melasma.

Melanin is produced by special cells called Melanocytes in the basal layer ( i.e. stratum germinativum) of the skin. When these cells get damaged, it directly affects on the production and quality of melanin & as a result pigmentation patches are formed on the skin.

The  production of the coloring agent Melanin in our skin is influenced by the hormones produced by the Endocrinol system.

Certain internal conditions such as menopause and related disorders have adverse effects on the Endocrinol system causing hormonal imbalance. This further results in an over- secretion of the coloring pigment.

Pigmentation is very commonly spread problem among the middle-aged women. Very few women in younger age suffer from this problem. It is related to the Endocrinol changes that occurs when women reach middle age.

The severity of pigmentation problem is associated with several diseases and disorders. To understand the unusual occurrence of pigmentation, we need to understand internal as well as external causes of pigmentation.

 Internal Factors Causing Pigmentation

Pigmentation of the skin can be the result of internal disorder in the body. We ought to make a correct diagnosis of these diseases and disorders so as to effectively clear up the pigmentation.

  1. An outbreak of freckles and dark spots all over the body could be due to Addison’s disease. This disease causes the damage and impairment of cortical part of the adrenal glands. The darkening of the skin in Addison’s disease is referred to as “ bronzing” and usually develops in the areas of the skin that are exposed to direct sunlight.
  2. Due to over absorption of iron from the food in the intestinal tract, a bronze pigmentation appears all over the body.
  3. When the skin turns bluish or purplish, it is due to the lack of oxygen in the blood. The oxygen- poor blood is bluish-red in color. Women suffering from pneumonia, lung diseases and some heart problems are troubled with this type of pigmentation.
  4. Menopause results in decline in the hormonal levels, which in turn affect the secretion of the coloring pigment in our skin. In case of surgical menopause by removal of ovaries and uterus, the pigmentation is more obvious and severe in nature.
  5. Sometimes, during pregnancy, dark brown spots appear predominantly on the face. The main reason for these brown spots is the hormonal imbalance caused during the pregnancy.
  6. Jaundice is another cause- the skin turns yellow due to the presence of excess bile in the blood and the body tissue. This disorder appears when the liver becomes incapacitated or when an obstruction appears in the bile tract.
  7. Deficiency of Iron, Calcium, Vitamin A, E & B complex result in patchy and spotty discoloration of the skin.

Lack of Vitamin A results in thickening and darkening of the skin. Vitamin E & B complex deficiency can cause excessive skin pigmentation problem.

External Factors Causing Pigmentation

There are three external factors that can cause Pigmentation of the skin.

  • Excessive Sun Exposure
    over exposure to sun without a shield tans and darkens the skin tone. The ultraviolet rays of the sun penetrate the skin and damage the skin cells.

    In the sun, the hormone MSH (Melanin Stimulate hormone) stimulates the melanocytes in the basal layer of the epidermis to produce melanin. The pigment protects the body from harmful effects of the sun’s rays since dark colors absorbs radiation.
    When the skin is exposed to UV radiation, melanocytes send more melanin to the surface of the skin.
    Melanin directly absorbs UV rays and attempts to prevent the skin from burning.
    As more melanin accumulates, the skin gets tan or freckle.
    Sunburn occurs when your skin cannot produce melanin quickly enough to prevent UV rays from injuring blood vessels close to the skin’s surface.

  • Use of wrong cosmetics
    Certain makeup products which have chemical colors, creams that have mercury drug preparations react adversely on the skin’s surface. The result is pigmentation.
  • Oral Medication
    The medicines prescribed for high blood pressure, asthma, diabetes, birth control and acne treatment have an unfavorable effect on the skin. More often, these medication cause spot pigmentation.

Types of Pigmentation

It’s important to correctly diagnose the cause and type of pigmentation to ensure we take best approach. There are two major types of Pigmentation

Hyper-pigmentation

Hypo-pigmentation

Hyper-pigmentation

Hyper-pigmentation occurs when skin produces more melanin. This can create patches or spots on skin appear darker than the surrounding area.

Melasma is dark skin discoloration or tanning of skin due to hormonal changes during pregnancy, exposure to sun, skin irritation. It can fade with time.

Freckles are small yellow-brown spots which are more likely result of the excessive sunlight exposure. But sometimes they can be genetic and appear from the childhood.

PIH (Post Inflammatory hyper pigmentation) appears in response to the inflammation of the skin. It is usually triggered by acne, a wound, rash that causes inflammation of the skin. It is usually in pink, red, brown, black in color.

Sunburn is a reddish type of skin discoloration and occurs due to over sun exposure. This type of pigmentation is very common with the fairer or lighter skin type.

 Hypo-Pigmentation

Hypo-pigmentation is result of lack of pigment i.e. reduction in melanin production. In this type of pigmentation skin becomes lighter or whiter than the normal.
Albinism is a result of complete or partial absence of melanin pigment in the body and includes skin, hair and eyes. Albinism is an inherited disorder.
A defect in one of the several genes that produce or distribute melanin causes albinism.
The person facing this kind of pigmentation problem is at high risk of developing skin cancer. They are very sensitive to harsh light or sunlight.

Vitiligo  is a condition in which smooth white patches develop on the skin because the pigment forming cells i.e. melanocytes are destroyed. It might be an autoimmune condition, in which melanocytes are destroyed by the body’s immune system.
