Hyperpigmentation on the face is when patches of skin become darker than the normal skin around it. The condition is common, is usually harmless and can occur for a variety of reasons.
Cause
Hyperpigmentation mainly occurs when too much melanin, the pigment that gives skin its coloring, is produced and then leaves deposits on the skin.
Types
Dark patches commonly called age spots or liver spots are also a common form of hyperpigmentation. They occur from sun damage, and usually show up on the face and hands.
Significance
People of any race can experience hyperpigmentation on their face or elsewhere on their bodies.
Considerations
Hormonal changes can play a role in hyperpigmentation. For example, pregnant women may experience an excess of melanin, giving them dark spots on their skin, typically the face. Birth control pills can also trigger overproduction of melanin. The condition will go away once hormones return to normal.
Treatment
Scars that result from surgeries, injuries or acne are considered hyperpigmentation. Laser treatments can be effective in removing the dark patches.
