Hyperpigmentation, often known as dark patches on the skin, happens when specific parts of the skin generate more melanin than usual. The eyes, skin, and hair are coloured by melanin.
Although some people may decide to have dark spots on their skin removed for aesthetic reasons, they are not dangerous and do not require treatment. People may refer to various forms of dark patches on the skin as age spots or sunspots depending on the reason.
In this article, we’ll examine what are the causes and symptoms of black spots on the skin.
Skin discolorations can be pale brown or dark brown in colour. The tone of a person’s skin may affect the hue of black patches. The patches are not unpleasant and have the same texture as the surrounding skin.
Dark spots can appear on any region of the body and come in a variety of sizes, although they are more prevalent in locations that are frequently exposed to the sun.
These places are prone to dark spots:
Dark spots can have a variety of reasons, which we list here:
People can develop dark spots on their skin as a result of exposure to the sun or tanning beds. These spots are also known as liver spots, solar lentigines, or sunspots.
Sun spots are more likely to appear on parts of the body that are exposed to the sun the most, such as the face, hands, or arms.
Small patches of skin discolouration are a symptom of the skin disorder melasma. Women are more likely to have the illness, particularly during pregnancy.
Hormones may cause melasma, according to the American Academy of Dermatology.
Dark patches on the skin might result from some drugs’ increased skin pigmentation. Tetracyclines, psychiatric medicines, and non-steroidal anti-inflammatory drugs (NSAIDs) are the main offenders.
Following an episode of skin inflammation, dark patches may form. Eczema, psoriasis, skin injuries, acne, and other conditions can all cause inflammation.
After an insect bite, burn, or wound has healed, dark patches could still be present. They could disappear with time.
Cosmetic skin care or hair products can irritate the skin and lead to the development of dark spots.
Diabetes can make some skin pigmentations darker.
Diabetes-related conditions include acanthosis nigricans, which results in velvety, dark skin, and shin patches or diabetic dermopathy, which some people mistake for ageing spots.
By looking at the spots and collecting a medical history, a doctor or dermatologist can frequently determine the reason of black spots on the skin.
The medical practitioner may do a Wood’s lamp skin exam during a physical examination, which involves looking at the spots with a specialized black light source.
In rare cases, a spot’s unique features may call for further testing to rule out skin cancer as the cause.
