Your body produces a pigment which is responsible for darkening of the skin called melanin. It is necessary to protect your body from the dangerous effects of sun's rays. As people with light skin tones have comparatively less melanin and hence, they are more prone to several skin issues.
The brown spots on your skin are among such skin issues. However, they are not only restricted to fair people. Their occurrence is quite common in people with darker skin tones as well.
The foremost cause is aging. It is believed that as you grow older, your body tends to produce more melanin. The effect is often seen in the form of flat, brown, gray or black spots on different body parts of your body.
The brown caused by aging are more commonly known as age spots, solar lentigines, and liver spots. Such spots are quite common in people who are over age 40. However, they may occur in young people as well. The age spots are harmless and often do not need medical treatment.
Another reason can be the frequent exposure to the harmful ultraviolet rays of the sun. Your body produces more melanin in order to protect the skin from the harmful effects of sun's rays.
Increased production of melanin results in formation of clusters of melanin in some parts of the body, such as legs, ankles, arms, etc. They occur as flat brown patches on the skin. Sun spots can also occur as white spots on the skin in some cases. Although they are painless, they may or may not be a sign of skin cancer.
The brown spots on legs and arms can be lentigos. They are a type of freckle which looks like a small tan. The lentigos are brown, sometimes black, spots on the skin. They are mostly caused by sun exposure. In fair-skinned people, they may occur due to some genetic abnormality.
Lentigos are harmless but may look like skin cancer spots. Hence, medical intervention is required for differentiation.
