Dark Spots On The Legs: Causes, DIY Home Remedies, & Treatment

What Causes Dark Spots On The Legs?

You can develop hyperpigmentation or dark spots on your legs for various reasons:

1. Excessive Sun Exposure

Dark spots typically occur due to excessive sun exposure and UV damage. The UV rays trigger your skin to produce melanin to protect itself from them. However, some areas may produce excess melanin, making them appear darker than the surrounding skin. Prolonged sun exposure can also lead to sunspots and skin cancer, especially in fair skinned people.

A national text message-based survey was conducted on 977 participants to study the sun protection knowledge, experience, and behaviors of the US youth. Only 62.1% of the participants stated sun protection as very important, 25.5% as important, and 5.4% as somewhat important.

2. Shaving Improperly

Improper shaving techniques can cause tiny black spots on the legs, also known as strawberry skin. This is different from hyperpigmentation and occurs in a pattern that closely matches the skin pores and hair follicles.

This harmless skin condition is caused when you use old and dull razors, pulling methods of hair removal like hot wax, leading to ingrown hair, clogged pores, rough dark patches, tiny bumps and pigmentation.

3. Melanoma

Black and brown spots on your legs can also be a dangerous skin disease called melanoma, a type of skin cancer (1). These spots generally develop in the lower legs and tend to change color and size. Melanoma on the skin is caused by excessive exposure to UV rays and using sunbeds for fake tanning. If you notice any changes in the dark spots on your legs, get them examined by a healthcare professional as early as possible.

As per the statistics provided by the Centers for Disease Control and Prevention, the prevalence of melanoma increases as you age. The increasing age is the most important risk factor among the US population. Check out the graph below to know the rate of melanoma among the US population by age.

4. Clogged Pores

Just like your face, the pores on your legs can get clogged with bacteria, dead skin, and sebum. Acne-prone skin, in particular, tends to produce more oil and shed cells rapidly. As a result, you will notice small black spots on your legs.

5. Folliculitis

Folliculitis is the inflammation of hair follicles caused by Staphylococcus aureus bacteria or other non-infectious factors like improper shaving, waxing, and wearing tight clothes (2). This leads to red and itchy acne-like bumps across your legs that gradually turn dark.

Mild folliculitis may go away on its own. However, if left untreated, the infection can cause permanent dark spots or scarring and other skin issues in the long run.

6. Keratosis Pilaris

Keratosis pilaris or ‘chicken skin’ is a skin condition characterized by tiny red or brown bumps on your skin (3). They most commonly appear on the outer sides of both arms but may present on the thighs and buttocks as well. They are caused by excessive keratin production, which blocks the hair follicles, leading to bumps.

Although there is no cure for it yet, skin care practices like exfoliation and moisturizing can reduce the bumpy texture of your skin and improve the appearance of your legs.

7. Diabetic Dermopathy

Diabetic dermopathy is a condition in which you develop dark spots on the lower legs. These marks are also known as shin spots and are common in patients with diabetes over the age of 50. There are no definite causes of this condition. However, the spots are thought to be caused by the excessive dryness of the skin and damaged blood vessels close to the skin layer. They tend to fade once the sugar levels are under control.

Different underlying conditions and external factors can lead to skin discoloration or pigmentation on the legs. If your dark spots are caused by an underlying condition, treating it may fade them. However, if they are due to external factors and improper skin care, you can try the following treatment options to get rid of them.

Consuming certain food items may affect your skin and lead to pigmentation issues. Learn more in the following section.

What Food Causes Dark Spots On Skin?

• Dairy Products: Milk and derived products like cheese and yogurt may cause or worsen acne breakouts (4). These flare-ups can leave behind pigmented spots.
• Sugars And Carbs: Food items with high sugar and carbohydrate content have a high glycemic index and may exacerbate acne and lead to acne spots (5).
• Fried Foods: Indulging in fried foods regularly could result in moderate to severe acne (6). Severe acne breakouts often cause spots and scarring.
• Alcohol: Alcohol can dehydrate your skin, making it appear dull. Further, its abuse is associated with inflammatory skin disorders and hyperpigmentation (7).
• Caffeine: Excessive caffeine can increase cortisol levels, leading to stress and related skin problems that may lead to pigmentation (8).

Let us now learn of some methods to treat dark spots on the legs.

How To Prevent Dark Spots On The Legs

1. Shave Properly

Lubricating the skin and using a sharp and new razor is crucial to prevent razor bumps and dark spots. Use a shaving foam and shave against the direction of hair growth. Exfoliate before shaving and moisturize the skin after shaving.

2. Exfoliation

Use exfoliants and physical scrubs to unclog the pores and prevent ingrown hairs.

Moisturizers keep your skin soft and offer some relief from dryness and inflammation after shaving and exfoliation. Use lotions rich in plant oils and shea butter and always apply them on damp skin to guarantee optimal hydration by trapping the moisture in your skin for longer.

4. Wear Sunscreen When Stepping Out

Use a broad-spectrum sunscreen on your legs and other exposed areas. Make sure to reapply your sunscreen every 40-80 minutes for maximum protection. Use a sunscreen with a minimum SPF 30 and PA ++++ rating to prevent UVA and UVB damage.

We have addressed a few queries regarding skin discoloration in the legs and ankles in the next sections. Take a look.

Why Does My Ankle Look Darker Than My Legs?

The ankles look darker in people with dark skin tones as compared to light skin tones due to multiple reasons. Generally, it is the natural tendency of the skin on the ankles, elbows, knees, and knuckles of the fingers to develop dark color or become tanned in people with dark skin tones.

Dark spots and marks around the ankles may occur due to hemosiderin staining or chronic venous insufficiency (14). This occurs when blood leaks from the capillaries and pools under the skin, leaving a hemoglobin residue that accumulates in the tissues. Over time, the spot may appear darker than the surrounding skin and turn black.

If you notice reddish-brown spots on your ankles, along with swelling or aches, consult your physician immediately.

Why Are My Knees Discolored?

Hyperpigmentation on the knees results from friction, which triggers melanin production in the area. It may also be caused by excessive UV rays exposure and clogged skin pores around the knees.

Regular exfoliation and a broad-spectrum sunblock can help eliminate discoloration in the knees. In some cases, your dermatologist may prescribe hydroquinoneⁱ  XA skin-lightening agent that bleaches the skin by decreasing the number of melanocytes (cells that contain the pigment melanin). creams to reduce the darkening.
