Hyperpigmentation dermatosis

Hyperpigmentation dermatosis

Uneven skin colour becomes a serious concern. One such concern is hyperpigmentation dermatosis where certain area of skin becomes darker compared to other parts. It may affect the person aesthetically and psychologically too. This happens due to increased production or deposition of the melanin, the skin pigment in affected skin area which would have been triggered by multiple reasons. It is categorized in different types as –

  • Post-inflammatory hyperpigmentation caused due to inflammation following an injury, or trauma like acne, psoriasis, eczema, or allergic reactions.
  • Melasma is patterned hyperpigmentation seen on female faces in butterfly shape during pregnancy, use of oral contraceptives. This must be because of hormonal imbalance.
  • Age spots or Solar lentigines due to over-exposure to sun rays.
  • Drug-induced hyperpigmentation is a result of certain medication’s side effect like anti-malarials, chemotherapy drugs, non-steroidal anti-inflammatory drugs (NSAID).

Depending upon the cause and severity the treatment option is recommended by the healthcare provider like topical exfoliating creams, chemical peel, laser or light therapy. Personal skin care is  must to maintain the outcome of treatment for longer duration.
