Pigmentation
Hyperpigmentation is defined as darkening patches of skin. This occurs when the skin produces more melanin, the pigment that gives skin its colour. Sun damage is the main cause of pigmentation. The initial melanin production from sun exposure acts as a natural sun screen to protect from harmful rays. However excess UVA/UVB exposure disrupts the melanin production, which leads to increased pigmentation.
