Age-Spots-and-Skin-Hyperpigmentation

Our skin color depends on our genetics and exposure to the sun’s UV rays mostly. The skin’s color comes from a pigment known as “Melanin” which is produced by specialized cells called “Melanocytes”. Melanocytes are found in the basal layer of the skin’s epidermis. Melanin is produced by a process called “Melanogenesis”. Darker skinned individuals possess more melanin compared to lighter skinned people. Melanin has a protective feature against the sun’s ultraviolet rays as well.

Mainly, genetics are responsible for providing your skin, hair, and eyes their color. The more the melanin, the darker the color. However, skin color can be quite uneven, person to person. Your soles and palms are lighter compared to other parts of your body. Such variation is noticed in a single part of the body as well, such as the face. Some parts of the face of an individual may be hyperpigmented while the others may be lighter.

Hyperpigmentation could be due to excessive sun exposure, or as a result of an underlying pigmentation disorder. Mild hyperpigmentation can be ignored and poses no trouble for people but if there are uneven hyperpigmented areas on a person’s body, especially on the face or hands, people tend to become quite conscious of themselves.

There are various causes of hyperpigmentation. These include:

  • Genetic Predisposition
  • Ageing / Age Spots
  • Excessive exposure to the sun’s UV rays
  • Hormonal Imbalance
  • Skin Allergies
  • Use of unsuitable and frequent beauty products/creams/ointments, etc.
  • Skin injuries
  • Lack in Vitamin B12
  • Post-inflammatory hyperpigmentation
  • Use of certain drugs such as ACTH analogs, progestogens, and estrogens, psoralens, busulfan, arsenic, anti-depressants, etc.
  • Underlying medical conditions – melasma, lichen planus, pellagra, Addison’s disease, etc.
  • Certain skin tumors – Acanthosis Nigricans, melanoma, etc.

Treatment:

The first and foremost step is to consult a dermatologist regarding any unusual patch of hyperpigmentation you may come across. Majority of the skin pigmentation you develop is harmless and goes away quite easily, either on its own or with the help of an ointment prescribed by the doctor. However, there is always a minute chance of it being something more serious. Hence, it is advised to consult a dermatologist, just to be on the safe side.
