What Is Mottled Skin?

What Is Mottled Skin

Key Takeaways

  1. Mottled skin is characterized by blotchy, discolored patches on the skin that can appear red, purple, or blue. It is caused by changes in blood flow through small vessels near the skin’s surface.
  2. Common causes of mottled skin include poor circulation, temperature changes, certain medications, and underlying medical conditions like lupus, Raynaud’s disease, and sepsis.
  3. Treatment for mottled skin depends on the underlying cause but may involve improving circulation through exercise and lifestyle changes, treating any related medical conditions, protecting the skin from extreme temperatures, and keeping the skin moisturized.

Mottled skin, also known as livedo reticularis, is a condition characterized by patchy, discolored areas on the skin. These patches may appear red, purple, or blue and can occur in a variety of patterns, such as a lace-like or fishnet-like appearance. The discoloration is caused by changes in blood flow through the small blood vessels near the surface of the skin. 

Mottled skin can affect any part of the body but is most commonly seen on the legs, arms, and trunk. It may be more noticeable in cold temperatures or when the skin is exposed to air. In some cases, mottled skin may be accompanied by other symptoms, such as numbness, tingling, or pain in the affected area. While mottled skin is not always a cause for concern, it can sometimes be a sign of an underlying health condition that requires medical attention.

Causes Of Mottled Skin

Many things can cause mottled skin. Let’s have a look at its most common culprits. 

Poor Blood Circulation

When blood doesn’t flow properly through the body, it can cause the skin to look mottled. A variety of factors can be behind this condition:

  • Maintaining a posture, be it sitting or standing for a long time
  • Wearing tight clothing that restricts blood flow
  • Having a medical condition that affects blood circulation, such as diabetes or peripheral artery disease

Temperature Changes

Sudden temperature changes can also cause mottled skin. When the body is exposed to cold temperatures, the blood vessels constrict to conserve heat. This can cause the skin to look mottled or blotchy. On the other hand, when the body is exposed to hot temperatures, the blood vessels dilate to help cool the body down. This can also cause the skin to look mottled.


Some medications can cause mottled skin as a side effect. These include:

  • Beta-blockers, which are used to treat high blood pressure and heart conditions
  • Vasopressors, which are used to treat low blood pressure
  • Certain chemotherapy drugs

Medical Conditions

Various health problems can also trigger mottled skin:

  • Lupus, an autoimmune disorder, can lead to skin inflammation and damage, resulting in a mottled appearance.
  • Raynaud’s disease causes blood vessels to constrict in response to cold or stress, which can cause the skin to look mottled.
  • Sepsis, a potentially fatal condition caused by the body’s reaction to an infection, can also lead to mottled skin as a result of the body’s response to the infection.

Symptoms Of Mottled Skin

The main symptom of mottled skin is the appearance of blotchy or discolored patches on the skin. These patches may be red, purple, or blue and may feel cold to the touch. Other symptoms may include:

  • Numbness or tingling in the affected area
  • Pain or discomfort in the affected area
  • Swelling in the affected area

If you experience any of these symptoms along with mottled skin, it’s important to see a doctor right away.

Is there A Treatment For Mottled Skin?

The treatment for mottled skin depends on the underlying cause. Here are some common treatments:

Improving Blood Circulation

If poor blood circulation is causing your mottled skin, there are several things you can do to improve it:

  • Exercise regularly to get your blood flowing
  • Try to avoid staying in a single position, be it sitting or standing for a long time 
  • Make sure that you wear loose comfortable clothing 
  • Quit smoking, which can damage blood vessels and reduce circulation

Treating Underlying Medical Conditions

If an underlying medical condition is causing your mottled skin, treating that condition can help improve your symptoms. For example:

  • If you have lupus, your doctor may prescribe medications to reduce inflammation and prevent damage to the skin.
  • If you have Raynaud’s disease, your doctor may recommend lifestyle changes, such as avoiding cold temperatures and wearing gloves, to prevent attacks.
  • If you have sepsis, you’ll need prompt treatment with antibiotics and supportive care to prevent complications.

Protecting Your Skin

In addition to treating the underlying cause of your mottled skin, there are several things you can do to protect your skin:

  • Avoid extreme temperatures, both hot and cold
  • Gentle, fragrance-free moisturizers can be used to keep your skin hydrated
  • Wear protective clothing, such as gloves and a hat, when you’re outside in cold weather
  • Always use sunscreen to keep your skin away from sun damage  


In conclusion, mottled skin is a common condition that can have a variety of causes, from poor circulation to underlying health problems. By understanding the symptoms and risk factors, you can take steps to prevent and treat this condition. Whether it’s making lifestyle changes to improve circulation, treating underlying medical conditions, adjusting medications, or protecting your skin from the elements, there are many ways to reduce the appearance of mottled skin and keep your skin healthy and radiant. 

Remember, if you notice any unusual changes in your skin, it’s always best to consult with a healthcare professional to rule out any serious underlying conditions. With the right treatment and care, you can help your skin look and feel its best. So, what steps will you take to prevent and treat mottled skin?
