The hormone Melanin regulates your skin’s Pigmentation. When the cells creating Melanin become damaged or unhealthy it can affect the amount of Melanin produced. Some pigmentation conditions can cause patches on the skin or affect the whole body.
Hyper pigmentation or Melasma is when your body produces too much Melanin, leading to areas of darker looking skin. This can be caused by skin exposure, inflammation and injury to the skin (especially in people of colour), pregnancy or disease.
Lack of Melanin can cause to lighter patches of skin which is known as Vitiligo
