What Causes Dark Spots (Black & Brown) on Your Legs and How Treat them?

Black Spots on Legs

Dark spots on legs can manifest in many different ways. Sometimes they may look like black spots on the legs or dark patches on the legs. This is caused by hyperpigmentation on legs, which occurs when the skin produces excess melanin in this area of the body. Melanin is the pigment responsible for giving color to the skin, hair, and eyes. Several factors can contribute to the uneven distribution of melanin, leading to the appearance of dark spots.

People of all skin tones can have dark skin spots on their legs or black spots on their legs, and that should not worry you. Not only can you have dark spots on your leg but also in some other parts of your skin. This article describes the causes of black spots on the leg, Laser Dark Spot Removal, Dark Spot Removal Treatment, and Dark Spot Treatment Miami.

Some of the most common causes of brown spots on legs include sun exposure, skin injuries or inflammation, hormonal changes, and aging. 

Brown Spots on LegsCauses of Dark Spots on Legs:

Sun Burn

Our skins produce melanin as a way of reacting to the sun. Some dark patches on the skin produce a lot of melanin, while others produce less. Too much sun causes dark spots on the legs or sun spots on the legs, and it is one of the leading cause causes.

Post-inflammatory Hyperpigmentation

This cause occurs when one has suffered from acne or has had some skin injuries. Such factors cause inflammation in the areas affected resulting in increased production of melanin. Once melanin has been produced, it forms a dark spot on your skin and minimally invasive treatments for vein removal.

Certain dietary choices contribute to hyperpigmentation. You might be wondering what food causes dark spots on the skin, and those include anything that is highly processed, as these types of foods contribute to inflammation and oxidative stress, potentially impacting skin health. Additionally, consuming excess sugar has been linked to the production of advanced glycation end products (AGEs), which may contribute to premature aging and skin damage.

Ultraviolet (UV) Rays

If you’ve had an injury to the skin, there is inevitably going to be some kind of scar as a result. Whether it’s a scar from a cut, burn, insect bite, or even surgery, hyperpigmentation may occur and result in the formation of black spots on the legs. Inflammatory skin conditions, such as eczema or psoriasis, can also contribute to this issue. Hormonal fluctuations are another cause of these dark spots. This is especially prevalent during pregnancy or due to the use of birth control pills, as both of these things can lead to melasma, which is a condition characterized by the development of a brown spot on legs and other areas of the skin.

Lastly, even something as simple as the natural aging process can result in black spots on the skin. The skin goes through changes as it ages, which leads to age spots. You might notice these black dots on the skin in areas such as the legs, arms, and other commonly exposed areas.


Patients who have insulin-dependent diabetes always have a problem with insulin production. If the body does not utilize insulin, it tends to accumulate in the bloodstream causing dark spots on the legs and black dots on the skin.

2. Processed Foods: Processed foods often contain trans fats and refined carbohydrates that can negatively impact skin health.

3. Dairy Products: Some individuals may experience acne flare-ups due to dairy consumption, potentially leading to dark spots.

4. Spicy Foods: Spicy foods can dilate blood vessels, and leaky veins leading to redness and potentially exacerbating existing dark spots.

If you are wondering what causes dark spots on my legs, do not worry. Many people, of all skin tones, have dark spots on various parts of the body. Dark spots on your legs can be a result of a variety of things, but there are five main causes for these dark spots on your legs: sunburn, diabetes, Melanoma skin cancer, and post-inflammatory hyperpigmentation, which can occur because of acne scars or a skin injury. Addison’s Disease can also cause dark spots on the legs. This rare disease causes hyperpigmentation in areas of the skin that are exposed to the sun.

2. How can I remove dark spots on my legs?

The most effective way to remove dark spots on legs is through laser treatment, such as PicoWay®. The exact type of treatment used depends on the actual cause of the spots, so it is important to consult with a medical professional before deciding on a procedure to follow through with. The two main options include using target beams of light to get rid of the actual layer of skin where the dark spots occur or using targeted beams of light to tighten the skin surrounding the dark spots and promote collagen growth.

Laser treatments for dark spot removal do not cause discomfort and do not require any surgery or downtime. These treatments can be done alone or can be combined with other treatment options if needed to remove black spots on the legs.

3. Which deficiency causes black spots on the legs?

Diabetes is a disease in which the body is not able to produce or respond to the hormone insulin properly. If you are someone who has insulin-dependent diabetes and is deficient in insulin production, that means the body is not properly using insulin. It can build up in the bloodstream and lead to dark spots on the skin and black patches on the legs, black spots on legs, and elsewhere on the body.

While a black spot on leg can be a cosmetic concern, they are often manageable with proper skincare and lifestyle choices. Thankfully, there are also safe and effective laser treatments that can help reduce the appearance of any brown spot on skin. Contact our office to schedule a consultation with our team and learn about your laser treatment options at Fox Vein & Laser Experts. 

4. Which vitamin is good for dark spots?

Three main vitamins are recommended to help with dark spots on the legs or any hyperpigmentation of the skin: vitamin C, vitamin B12, and vitamin E. Both vitamin C and B12 are useful for promoting collagen production in the skin, while vitamin C also inhibits melanin and vitamin B12 helps new skin cells grow. Vitamin E is most well known for its ability to help with scarring, and this can also decrease the appearance of black marks on legs or anywhere on the body the spots may appear.

5. How can I lighten the dark scars on my legs?

In addition to laser treatments, taking vitamins C, B12 and E can help to lighten the dark spots and/or scars on your legs. Other home remedies include using essential oils and massaging and exfoliating the affected areas.

6. What do dark spots on the legs mean?

Dark spots on the legs are very common. It simply means that there is an excess of melanin being produced in certain areas of the body. Melanin is the substance in the body that provides pigment for eyes, hair, and skin tone. The amount of melanin differs from person to person due to genetics, but overall, those with higher levels of melanin will have darker skin, darker eyes, and darker hair. Dark spots can occur on other parts of the body as well, including the arms, chest, back, face, back of the hands, or tops of the feet.

7. Why do I have dark spots on my legs?

Dark spots are sometimes called sun spots. This is because melanin is produced as a reaction to sun exposure, and why skin appears darker after you have been out in the sun all day. When you get a sun tan or a sunburn, that is your body reacting to the sun and causing an excess of melanin in the areas that were exposed to the UV rays. Sun exposure is one of the top five causes of dark spots, and typically the most common. The other four are post-inflammatory hyperpigmentation on the legs, diabetes, Melanoma, and Addison’s Disease.

8. How to get rid of dark spots on your legs?

The most common treatments for dark spots are microdermabrasion, chemical peels, cryotherapy, and laser treatment, which tend to be the most effective. There are two different approaches to treating dark spots with a laser procedure. One uses the laser to eliminate the top layer of the skin and remove the affected skin cells, which is similar to what microdermabrasion and chemical peels also do, but the laser is much stronger. The other laser treatment option uses the laser to tighten the skin around the affected area and promote the natural production of collagen to decrease the appearance of the darker spots. You will need to schedule a consultation with one of the team members at Fox Vein & Laser Experts so that we can determine which treatment option will provide the most successful solution to treating your dark spots and age spots on legs.

There are also prescription and non-prescription creams that can help reduce the appearance, and natural remedies such as using essential oils, and products containing vitamin C, B12, and E, licorice extract, mulberry, soy, and niacinamide, can also help lighten up the spots.

9. Why do I have brown spots on my legs?

Sun exposure is the most common cause of brown spots on legs and skin, but this is not the only reason for these dark patches on legs and the body. Additional causes include:

1. Hormonal changes in the body due to puberty or pregnancy.
2. Inflammation is caused by acne, skin conditions like eczema and psoriasis, or any kind of injury to the skin.
3. Diabetes is a condition affecting the way the body produces insulin. When it does not properly use insulin, it pools in the bloodstream, and dark spots can appear.
4. Melanoma skin cancer.
5. Addison’s Disease, which is a lesser common condition, is an adrenal disease that decreases cortisol production in the body and causes hyperpigmentation.
6. Melasma is a skin condition that causes hyperpigmentation and is very common in pregnant women.

10. What food causes dark spots on the legs?

The main reasons for dark spots and brown spots on legs are sun exposure, diabetes, skin cancer, post-inflammatory hyperpigmentation, and Addison’s Disease but there is one more thing to add to that list: food. There are certain foods that you should avoid to decrease your risk of developing dark spots. Avoid food that is high in sugar because the high levels of sugar have the potential to cause inflammation in the skin and slow down the body’s natural collagen production process. The same goes for fried foods that are high in fat. These kinds of food can speed up the skin aging process, which is not something anyone wants! There is also a risk factor in foods that contain soy, as there is evidence that soy plays a role in hormone function.
