Hyperpigmentation is the medical term for the development of dark spots on the skin as a result of increased melanin production. The further classifications for these skin pigmentation issues include age spots, melasma, freckles, sun spots, and liver spots. Small patches of hyperpigmentation may be present, or it may cover larger areas like the face, hands, and arms.


The melanin-producing cells (melanocytes) that are present in the skin are also stimulated by sunlight, acne, and rashes, which results in them producing more melanin in the deeper layer of the skin. As a result of excessive melanin (the pigment that gives the skin colour) synthesis, which is a harmless disorder, black pigment deposits appear on the skin, making the skin appear darker in comparison to the healthy surrounding skin cells.

Increased hyperpigmentation is not hazardous and can be brought on by a variety of illnesses, including obesity, thyroid disorders, liver diseases, and pcod.

As melanin absorbs UV rays and protects the skin from damaging sun rays, these dark spots grow darker when exposed to sunlight. Overexposure to UV radiation results in tanning and makes already pigmented areas darker. Therefore, using broad-spectrum sunscreen is essential since it blocks dangerous UV radiation.

Possibile causes of hyperpigmentation

  • Increased melanin formation in the skin as a result of too much sun exposure
  • Using birth control, chemotherapy, anti-seizure medicine, and antibiotics
  • Acne healing
  • Alterations in hormones during pregnancy
  • Addison’s illness
  • Heredity
  • Ineffective skin treatments
  • Skin damage or injury
