Skin Pigmentation

Skin Pigmentation

The skin color is dependent on the pigment melanin in the melanocyte cell. Some are lighter fairer skin, other are yellow colored, still other are dark skinned or black.

Problems of skin pigmentation

When the skin color is uniform it has no problem but an issue when it is non uniform. This causes irregular discoloration or dyschromia. These coloration could be hyper or hypo pigmentation depending whether it is darker or lighter in color.

Hyperpigmentation

When the melanin production is increased, it cause hyperpigmentation. This may be regular and uniform in a young healthy skin. But it may be irregular in an older skin with long history of frequent and prolonged sun exposure.

There are various types of irregular pigmentation:

  • Melasma
    • This describes the general darkening of the face skin.
  • Chloasma
    • This describe the skin discoloration caused by the hormone. The big hormone changes during the pregnancy, the consumption of oral contraceptive pills, and the hormone replacement therapy usually is the estrogen replacement therapy.
  • Solar lentigo
    • This condition is frequently refereed to as “liver spot” or also called as “senile freckle”. This is incorrectly refereed to as liver spot which is not caused by the liver problems but rather from sun exposure. This is caused by none other than UV damage to the skin from the sun exposure, and subsequent darkening in an irregular manner.
    • on a fairer skin, solar lentigens appears as small brownish patches of freckling. This will grow and increase in number over area of most frequent sun exposure. It can appear on the face, hand, arm, leg, trunk….
