Hyperpigmentation is a skin condition in which patches of the skin become darker than the surrounding area. It can affect any part of the body, but hyperpigmentation on the face often causes emotional distress and social anxiety. There are various types of hyperpigmentation, each with its own set of causes and degrees of severity. Age spots (lentigo senilis), melasma (chloasma), freckles (ephelides or lentigines), solar lentigo, acne scars (keloids), and post-inflammatory hyperpigmentation are all examples of hyperpigmentation. Various factors such as sun exposure, burns, or acne lesions; hormone changes during pregnancy; and medications can cause hyperpigmentation.
Types of hyperpigmentation
Post-inflammatory and photoaging hyperpigmentation are classified as two types of hyperpigmentation. Erythema ab igne, which is brown pigmented lines on the skin caused by lengthy sitting or sunbathing near a source of intense heat, is one form of post-inflammatory hyperpigmentation. Solar lentigo, also known as liver spots or age spots that develop in adulthood after too much exposure to UV radiation from the sun, are another type. Drug-induced hyperpigmentation includes situations like Melanosis coli et., in which minocycline causes an increase in melanin synthesis in cells leading to darkening around the lips and mouth areas (Melanosis coli et.).
Types of photoaging include melasma which appears as dark brown patches on the skin with irregular borders.
What causes hyperpigmentation? What is hyperpigmentation? What does it look like?
– Hyperpigmentation occurs when too much melanin is produced in the body, giving an excess of dark patches. It mainly affects areas such as hands and feet but can also appear on other parts of the body. Symptoms include: discolouration, uneven skin tone and darker or lighter spots appearing suddenly or gradually over time with no obvious cause of it.
