Pigmentation refers to the unexplained darkening (hyperpigmentation) or lightening (hypopigmentation) of the skin. Causes can usually be pinpointed to UVR exposure, trauma, medication, a chemical substance, or hormonal and Vitamin A & C deficiencies. And not forgetting essential fatty acid deficiency. Other causes trigger skin diseases such as dermatitis, eczema and psoriasis.
Normal skin contains cells called melanocytes that produce melanin, the brown skin coloring pigment of the skin, and when these melanocytes are either abnormal or abnormally distributed, it results in pigmentation ‘problems’. Although most skin conditions that cause discoloration are harmless, people need to know when there is a cause for concern.
