What Are the Causes of Red Moles?

Updated July 19, 2017

Red moles are small growths that appear on the skin. Most individuals have at least one red mole somewhere on their body. When a mole develops later in life, it may become a cause for concern. There are a variety of reasons why red moles may develop.

Overexposure to the Sun

Red moles can develop because they have been triggered by overexposure to the harmful rays of the sun. They also may appear after a serious sunburn. These types of red moles can easily become irritated and may bleed if accidentally scratched.

If red moles appear as a result of a sunburn or constant sun exposure, it is wise to have a dermatologist check the mole as soon as possible. Early detection of skin cancer is the best way to prevent it from spreading.


The development of red moles can sometimes be linked to your family tree. Many types of skin conditions, including red moles, can develop simply because of heredity.

The only concern here would be if your family has a strong history of malignant, or cancerous, melanoma. If this is the case, it is important to keep a close eye on moles. Watch for changes in size, shape, or if they develop jagged edges. These can be dangerous signs and should be checked by a physician.


Pregnancy, although a wonderful time in a woman's life, can cause many changes in the skin. This is due to the extreme hormonal changes that take place in the body. A variety of changes to the skin can be a result of pregnancy. One of those changes includes the development of brown or red moles. Moles may grow larger during pregnancy or may even appear for the first time.

This is generally not a cause for concern and can even be expected. Remember to bring any skin developments to your doctor's attention during your next prenatal visit.


Red moles commonly occur in ageing skin. Whether this should be considered a natural part of ageing depends on the individual.

As a person advances in years, the skin can become more susceptible to changes. Be aware that certain changes may be a warning sign of an underlying medical condition. If you have experienced sunburn or blistering several times over the course of your life or suffer from a disease, you should make your physician aware of the appearance of red moles.

Treatment for Red Moles

Most of the time, moles are left alone unless there is a risk of melanoma. Your doctor may choose to remove one or two of your moles and send them in to be tested. Red moles also can be tested through a special instrument that uses high frequency ultrasound combined with colour Doppler to examine the skin.

If the test results are positive or suspicious, your physician may choose to remove the moles that are raised, discoloured, or have recently experienced changes in size or shape.
