The colouration of the skin shades darker or lighter than the usual skin colour is known as the skin pigmentation. Our skin gets its colour from a pigment, called melanin. Melanin is produced by melanocytes (the type of cells that are present in the basal layer of the epidermis) and is responsible for the colouration of skin, hair and eyes. It protects our skin from UVB radiation damage, thus reducing the risk of cancer.

What causes Skin Pigmentation?

Skin Pigmentation is caused by the increase in levels of melanin. It could be the result of inflammation (that occurs after treatment, like the laser), injury, sun damage or hormonal changes. Birthmarks and freckles are a different type of pigmentation, as they are genetically determined. The appearance of patches, however, can be the result of a disease, so it should be diagnosed as soon as possible.

What are Skin Pigmentation Disorders?

Pigmentation is the colouring of an individual’s skin. The colour of the skin appears normal when a person is healthy. A person’s skin may change colour and grow darker (hyperpigmentation) or lighter (hypopigmentation) because of illness and injury. Below are some of the Pigmentation Disorders:

Skin Pigmentation

A.Hyperpigmentation

It is the darkening of an area of skin or nails caused by increased melanin. Conditions such as pregnancy or decreased function of the adrenal gland (Addison’s disease), may cause a greater production of melanin. One of the leading causes of hyperpigmentation is exposure to sunlight. It can also be caused by various drugs, including some antibiotics, antiarrhythmics, and antimalarial drugs. An example of hyperpigmentation is Melasma which is characterised by tan or brown patches, most commonly on the face.

B.Hypopigmentation

It is the loss of skin colour which is caused by melanin depletion. Examples of Hypopigmentation are:

C.Vitiligo

Vitiligo is an autoimmune, disease in which there is an appearance of smooth, white patches on the skin occur all over the body.

D.Albinism

It is a rare inherited disorder which is caused by the absence of an enzyme that produces melanin. Pigmentation is completely lost as a result in eyes, skin and hair.

E.Pityriasis Alba

It most commonly affects children and is characterised by colourless, scaly skin patches.

F.Seborrheic Dermatitis

It is an inflammatory skin disease which is marked by red, scaly, itchy patches of skin in oil prone areas.

G.Tinea Versicolor

It is caused by fungal infection and characterised by itchy, scaly patches of lighter or pinkish skin.

H.De-pigmentation

It is the lightening of the skin or loss of pigment. It can be caused by many local and systemic conditions. The loss of pigment can be partial (caused because of injury to the skin) or complete (caused by Vitiligo). It can be temporary or permanent.

Diagnosis of Pigmentation

Pigmentation is visible to naked eyes, but it takes 10-20 years for a scar to develop. So, we can say that these don’t develop suddenly but over a period. Diagnosis of Pigmentation can be made by Wood Lamp’s Examination.Wood’s lamp is a device that emits light in the 365-nanometer range and is used by the skin specialists.
The test is performed in a dark area, allowing the light emitted by the device to glow on the affected area for a small period and looking for any changes in colour or fluorescence. If the skin is healthy, then it won’t fluoresce under Wood’s Lamplight.

Treatment for Pigmentation

Pigmentation is treated mostly through three chemical methods.

1. Chemical Peel

Chemical peels are used by Dermatologists to enhance the appearance of skin. In this process, a chemical solution is applied to the skin that exfoliates it and eventually leads it to come off. The newly made skin is smoother and less wrinkled as compared to the old skin. But, the new skin becomes more sensitive to sunlight.

2) Dermabrasion

Dermabrasion is a kind of cosmetic surgery which involves removal of the superficial layers of skin with the help of a rapidly revolving tool, mostly made up of a diamond.

3) Laser Resurfacing

It is a process which uses a laser to treat minor facial flaws by removing layers of skin. Healing takes around ten days.
