Dark spots on the legs: 4 reasons why you have them and how to get rid of them

Sun exposure, injury, and hormonal fluctuations can cause dark spots on the legs. In fact, health conditions such as diabetes can also cause hyperpigmentation. Sometimes, black spots are also caused by excessive melanin production in certain parts of the skin. The higher your melanin levels, the darker your skin. Although these spots are not dangerous (most of the time), treatment of these spots depends on the cause of the spots. However, apart from OTC medications, there are some simple and easy home remedies that can help you get rid of black spots on legs in no time. In fact, it is also useful for preventing further black spots from appearing.

What are black spots?

Black spots on the legs are patches of skin that are darker in color than the surrounding skin. This is often caused by an increase in melanin, the pigment that gives skin its color, as research published in Molecules found. These black spots vary in size, shape, and intensity, and can appear on any part of the foot. Additionally, black spots and patches indicate that certain areas have more melanin.

Dark patches on the skin are usually uniform in color, without clear borders or patterns. They usually appear flat on the surface of the skin. Apart from that, these black spots usually do not cause itching or pain.

Causes of black spots on the legs

Here are some common causes of black spots on the legs.

1. Sun exposure

The sun’s ultraviolet (UV) rays play an important role in the appearance of dark spots on the legs, according to a study published in the International Journal of Molecular Sciences. When the skin is exposed to excessive sunlight, the body’s natural defense mechanism is to produce more melanin, the pigment that gives skin its color. This increased production of melanin can cause darker patches of skin, which are often referred to as sunspots or age spots. The types of UV rays that contribute most to the formation of black spots are UVA and UVB rays. UVA rays penetrate deeper into the skin and can cause long-term damage, including premature aging and an increased risk of skin cancer. UVB rays primarily cause sunburn, but can also cause hyperpigmentation.

2. Hormonal changes

Hormonal fluctuations can be an important factor in the appearance of black spots on the legs. During pregnancy, hormonal changes can cause increased melanin production, resulting in hyperpigmentation, says a study published in the journal Pigment International. This is often referred to as ‘mask of pregnancy’ or melasma, and usually appears as dark patches on the face, but can also occur on the legs. Additionally, menopause is a time of significant hormonal changes, and can also cause hyperpigmentation, as research published in the journal Cosmetics found. When estrogen levels decrease, the skin may become more sensitive to sunlight and other environmental factors, leading to increased melanin production. While hormonal changes are often associated with dark spots, it’s important to note that not everyone experiences hyperpigmentation around this time. The extent to which hormones influence skin pigmentation can vary from person to person.

3. Injury and skin inflammation

Injury or inflammation of the skin can trigger increased melanin production, leading to the formation of dark spots, according to a study published by StatPearls. When skin is damaged, the body’s repair mechanisms are activated, including increased melanin production. This may cause a darker patch of skin at the injury site. Some examples of skin injuries that can cause black spots include, minor skin injuries can cause hyperpigmentation while the skin is healing, burns whether due to sunlight, heat or chemicals can cause black spots to form, acne can leave black spots. , often referred to as post-inflammatory hyperpigmentation, and insect bites can sometimes cause dark spots.

4. Genetics

Genetics can play an important role in the appearance of dark spots on the legs. Some people may be genetically predisposed to hyperpigmentation, meaning they are more likely than others to experience dark spots. “This genetic predisposition can be inherited from parents or other family members. If you have a family history of dark spots, you are more likely to experience them too,” says cosmetologist and trichologist Dr Priti Mahire.
