What is Skin Discolouration? Its Signs and Causes?

 Colourderma:

Vitiligo is a skin disease that causes pigmentation of the skin in small patches. The areas that are discoloured tend to become larger with the passage of time. The condition could be affecting the skin on any body part. It could also impact your hair or the mouth's inside. The colour of hair and skin is affected by melanin.

Symptoms:

Vitiligo may begin at any time but typically is present before the age of 30.

Based on the kind of vitiligo you suffer from It could affect:



  • All skin types. In this kind of condition, referred to as universal vitiligo, skin discolouration is seen on almost all skin surfaces.

  • A variety of body parts. In this type known as generalised vitiligo, the discoloured patches tend to progress similarly across body areas.

  • One side or a portion or part of your body. This type, known as segmental vitiligo tends to develop at a younger age. It will last for a few years or so and eventually ceases.

  • A single part within the human body. This kind of vitiligo is known as localized (focal) vitiligo.

  • There are two areas to consider: the face as well as hands. When this is the case, it's called Acrofacial Vitiligo, the affected skin is located on the hands and face, face or hands as well as around the body openings like the nose, eyes and ears.

It's hard to know the course of this disease. Sometimes, the patches cease to form without treatment. In the majority of cases the loss of pigment spreads and eventually covers the majority part of your skin. In rare instances, the skin can get its colour back.



Causes:

Melanin and skin layers

Vitiligo happens when the pigment-producing cells cease producing melanin that provides the skin hair as well as your eyes colour. The skin patches affected are lighter or become white. It's not clear exactly what causes these pigment cells to cease to function or cease to function. It could be connected to:

  • A disease that affects the immune system 

  • The family history (heredity)

  • An event that triggers the reaction that triggers the body, for example, intense sunburn, stress, skin traumas or exposure to a chemical
