Melanin is the pigment that provides the tone and complexion to your skin. Over production or under-production of melanin can cause the skin to appear ashier or darker than normal. It can also result in an uneven skin tone. This can happen to due to various reasons like:

  • Ageing
  • Overexposure to the sun
  • Healing of a wound
  • Dryness of the skin, which leads to uneven skin colour
  • Nutrition deficiencies
  • Hormonal changes
