A lack of skin color caused by a deficiency of melanin production or a loss of pre-existing melanin or melanocytes.

If treatment of hyperpigmentation is desired, a dermatologist may be able to use dermabrasion, laser treatments, or bleaching agents to effect change.
Excess production of melanin pigment, resulting in darkening of the skin. Hypopigmentation- Lack production of melanin, causing ‘white spots' on skin
an increased level of coloring (melanin) in skin. Can be natural (sun tan) or pathological.

Hyperpigmentation may be due to hypermelanosis or haemosiderin deposits that result in skin colour that is darker than normal.
An over excitation of melanocytes, darkening of the skin. Can be seen as sun-induced freckles or melasma.
In dermatology, hyperpigmentation is the darkening of an area of skin or nails caused by increased melanin. Hyperpigmentation may be caused by sun damage, inflammation from acne, or other skin injuries. People with darker asian, east indian, middle eastern, hispanic, or african skin tones are also more prone to hyperpigmentation especially if they have excess sun exposure .
