Hyperpigmentation – also known as irregular pigmentation – consists of unwanted dark spots and discolouration on the face, hands and body. Excess production of melanin in the skin, as well as other factors, contribute to the formation of hyperpigmentation. Melanin production is stimulated by exposure to UV light. The condition is often aggravated by inflammation and a damaged skin barrier. The key to improving unwanted discolouration and prolonged prevention is limiting exposure to UV light and optimising the health of the skin barrier.
