These small brown lesions are a result of abnormal production and deposition of melanin by the melanocytes. Melanocytes are our pigment-producing cells. The number of melanocytes present in our skin will determine our skin colour.
Melanin gives our skin, hair and eyes its colour and pigment. The more melanin you have in your skin, the darker it will be. There are different types of pigmentation which can be caused by excessive sun exposure, genetics and hormonal changes.
Melasma most commonly shows up during pregnancy and gives a butterfly effect over the face.
Pigmentation spots which people commonly refer to as age spots or sun spots appear on the skin through sun exposure.
Post Inflammatory Hyperpigmentation (PIH) appears on the skin after trauma or a wound has been caused and the area heals with discoloration.
