Hyperpigmentation

Hyperpigmentation is the appearance of painless brown spots on areas of the skin, such as the face, hands, or even below the neck.

Hyperpigmentation is the appearance of painless brown spots on areas of the skin, such as the face, hands, or even below the neck.

Hyperpigmentation is caused by an overproduction of melanin, which is the pigment that determines the colour of the skin, eyes and hair. Melanin also shields the skin against UV rays. There are many causes of hyperpigmentation, most notably, overexposure to the sun, age, hormonal changes and even skin trauma.

Depending on the cause, hyperpigmentation appears in different forms, including melasma, lentigos, and post-inflammatory hyperpigmentation.

Melasma, known as the “pregnancy mask”, mainly affects women during pregnancy. It is frequently caused by hormonal changes and sun exposure, and is characterized by brown spots on the face.

Lentigos, commonly called “age spots,” are also caused by the sun and appear more frequently on the most exposed body parts such as hands, forearms, face and décolleté. Lentigos affect middle-aged people. The pigmentation gradually disappears.

Post-inflammatory hyperpigmentation is caused by skin trauma, infection or a medical reaction.  

Protecting the skin from sun exposure is the best way to prevent spots from appearing.
