Brown Spots in St. Louis

Age spots, also known as liver spots or lentigos, are flat brown or black marks that appear on the skin. These spots typically occur in areas exposed to the sun, such as the face, hands, shoulders, and arms. They result from an excess production of melanin in certain areas of the skin due to prolonged exposure to ultraviolet (UV) radiation from the sun or tanning beds. Age spots are harmless and generally do not require medical treatment, although they can be a cosmetic concern for some individuals, 


At Mid-County Dermatology located at Missouri Baptist Medical Center in St. Louis, MO, we perform skin cancer screenings to evaluate these age spots and ensure they are harmless. If you have not had a skin cancer screening examination, you can schedule yours now.

Recognizing the Signs and Causes of Age Spots

Age spots are a common skin condition that can affect people as they get older. These spots typically appear on areas of the body that have been exposed to the sun over time, such as the face, hands, shoulders, and arms. Understanding the causes and symptoms of age spots can help you identify and manage this condition effectively.

Prolonged exposure to UV light

The primary cause of age spots is prolonged exposure to ultraviolet (UV) light from the sun or tanning beds. When your skin is exposed to UV rays for an extended period, it triggers an increase in melanin production. Melanin gives color to your skin, hair, and eyes. However, excessive melanin production can lead to the formation of dark patches on your skin.

Appearance and color variations

The main symptom of age spots is the appearance of flat, oval-shaped patches on the skin that vary in color from light brown to dark black. These patches are usually painless and do not cause any physical discomfort. Age spots are commonly found in areas that receive the most sun exposure because they tend to develop due to accumulative damage over time.

Other contributing factors

While prolonged UV exposure is the primary cause of age spots, other factors may contribute to their development. Genetics play a role in determining how susceptible you are to developing age spots. If your parents or close relatives have had them before, you may be more prone to developing them too.

Differentiating age spots from other conditions

It's important to note that age spots differ from other skin conditions like melanoma or freckles. Melanoma is a type of skin cancer that can be life-threatening if not detected and treated early. Freckles, on the other hand, are small, light brown spots that are usually genetic and appear at a young age.

Age spots are generally harmless and do not require medical treatment. However, if you notice any changes in the size, shape, or color of your spots, it's essential to consult one of our dermatologists to rule out any underlying health concerns.

When to See a St. Louis Dermatologist for Your Age Spots

If you have age spots, also known as brown spots, you may be wondering if you need to seek medical care for their treatment. In most cases, medical care is unnecessary unless there are changes in their appearance or if they cause discomfort.

Changes in Appearance

One important factor to consider when deciding whether to seek medical care for age spots is any sudden change in size, shape, color, or texture. If you notice any of these changes occurring in your age spots, it's advisable to consult a healthcare professional.

Unusual Symptoms

Apart from changes in appearance, unusual symptoms associated with age spots can also indicate the need for medical attention. If you experience itching, bleeding, pain, or any other unusual symptoms related to your age spots, it's best to consult a dermatologist or healthcare provider.

It's important not to ignore these symptoms as they could potentially be signs of a more serious condition. Our St. Louis dermatology team will be able to evaluate your age spots and determine the appropriate course of action.

What happens when I see a dermatologist for brown spots?

Seeking medical care for your age spots often involves consulting with a dermatologist at Mid-County Dermatology. Our dermatologists are specialized doctors who focus on diagnosing and treating skin conditions and distinguishing age spots from skin cancer, like melanoma.

When you visit Mid-County Dermatology regarding your age spots, we will examine them closely and ask about any changes or symptoms you may have noticed. We may also inquire about your medical history and perform additional tests if necessary.

Based on our evaluation, our dermatology team will provide recommendations for treatment options that are suitable for your specific situation. These options may include topical creams or ointments that can help lighten the appearance of the age spots over time.

In some cases where the age spot is particularly bothersome or impacts your self-esteem, we may suggest procedures such as laser therapy or cryotherapy (freezing) to remove the spot completely.

Remember, age spots are generally harmless and do not require medical treatment. However, if you notice any changes in their appearance or experience unusual symptoms, it's always a good idea to consult a dermatologist for further evaluation and guidance.

By seeking medical care when necessary, you can ensure that your age spots are properly assessed and treated, giving you peace of mind and potentially improving the overall appearance of your skin.

Diagnosing Age Spots in St. Louis

To diagnose age spots, a visual examination by our dermatology team is usually the first step. We will carefully examine the affected area to determine if it is indeed an age spot. In some cases where there is uncertainty about the diagnosis or suspicion of another condition like melanoma, further tests may be necessary.

Biopsy for Uncertain Cases

If there are any doubts about the diagnosis or if the doctor suspects a more serious condition, they may recommend a biopsy. A biopsy involves removing a small sample of tissue from the affected area for further analysis under a microscope. This procedure helps rule out any underlying conditions and confirms whether it is indeed an age spot.

Ruling Out Melanoma

Melanoma is a type of skin cancer that can sometimes resemble age spots in its early stages. To ensure accurate diagnosis and rule out melanoma, dermatologists carefully analyze various factors such as size, shape, color variation, and borders of the brown spots. If they suspect melanoma or need more information to make an accurate diagnosis, they may recommend additional tests or refer you to an oncologist.

Other Diagnostic Procedures

In addition to visual examinations and biopsies, doctors may use other diagnostic procedures to evaluate age spots:

  • Wood's lamp examination: This test uses ultraviolet light to help identify certain pigmentation patterns that can differentiate between benign age spots and other skin conditions.

  • Dermoscopy: Using a handheld device called a dermoscope, doctors can examine the structure of the skin more closely, looking for any irregularities or signs of melanoma.

Effective Treatment Options for Age Spots in St. Louis

Age spots, also known as brown spots, can be a bothersome cosmetic concern for many people. Luckily, there are various treatment options available to help diminish the appearance of these spots and restore a more even complexion. Let's explore some of the most common treatment options for age spots.

Topical Creams

One popular treatment option for age spots is the use of topical creams. These creams often contain ingredients like hydroquinone or retinoids, which work to lighten the appearance of age spots over time. By applying these creams consistently, individuals may notice a gradual fading of their age spots. It's important to note that these creams may require several weeks or months of regular use before results become noticeable.

Laser Therapy

Laser therapy is another effective treatment option for age spots. This procedure involves using focused light energy to break down the pigment in the age spots, leading to their gradual fading. During laser therapy sessions, a dermatologist will carefully target and treat each spot. Multiple sessions may be required depending on the severity of the age spots and desired results.


Cryotherapy is a treatment option that involves freezing the age spots with liquid nitrogen to destroy the excess pigment. This process causes the treated skin to blister and eventually peel off, revealing new skin underneath. Cryotherapy is typically performed by a healthcare professional and may cause some discomfort during and after the procedure. However, it is generally well-tolerated by most individuals.

Chemical Peels

Chemical peels are another effective way to address age spots. This treatment involves applying a chemical solution to exfoliate and remove layers of damaged skin where age spots are present. As new skin regenerates, it appears smoother and more even-toned. Chemical peels can vary in strength depending on individual needs, so it's important to consult with a dermatologist who can recommend an appropriate peel for your specific case.


Dermabrasion is a treatment option that involves removing the outer layers of skin using a rotating brush or diamond wheel. This process helps to exfoliate and improve the appearance of age spots. Dermabrasion is typically performed by a dermatologist or plastic surgeon and may require multiple sessions for optimal results.

While these treatment options can be effective in reducing the appearance of age spots, it's important to remember that prevention is key. Protecting your skin from harmful ultraviolet (UV) radiation by wearing sunscreen, avoiding tanning beds, and seeking shade during peak sun hours can help prevent the development of new age spots.

Long-Term Strategies for Preventing Age Spots

It is important to note that age spots may recur after treatment if preventive measures are not taken. To effectively manage age spots and prevent their return, there are several key strategies to consider.

Protecting Your Skin from UV Radiation

One of the most crucial steps in managing age spots is protecting your skin from harmful UV radiation. This means wearing sunscreen with a high SPF regularly, even on cloudy days, and reapplying it every two hours when exposed to the sun. Wearing protective clothing such as hats and long sleeves can provide an extra layer of defense against UV rays.

Regularly Examining Your Skin for Changes

Another important aspect of managing age spots is regularly examining your skin for any changes. By closely monitoring your skin, you can catch any new or recurring age spots early on. If you notice any suspicious growths or changes in color or shape, it's essential to seek prompt medical attention from a dermatologist. Early detection can greatly increase the chances of successful treatment and prevent further recurrence.

Consistent Skincare Routine

Following a consistent skincare routine is vital in managing age spots effectively. Incorporating exfoliation into your routine helps remove dead skin cells and promote cell turnover, which can help fade existing age spots over time. Moisturizing daily keeps your skin hydrated and healthy, reducing the appearance of age spots.

A good skincare routine should also include products with ingredients like retinol or vitamin C that have been shown to help fade hyperpigmentation and even out skin tone. However, it's important to consult with a dermatologist before introducing new products into your routine to ensure they are suitable for your specific needs.

Lifestyle Changes

Making certain lifestyle changes can also contribute to managing age spots. For instance, quitting smoking can improve overall skin health and reduce the likelihood of age spots recurring. Maintaining a healthy diet rich in antioxidants and staying hydrated can support skin health and minimize the appearance of age spots.

Conclusion: Understanding Brown Spots

In conclusion, understanding brown spots is crucial for effectively managing and preventing their occurrence. Age spots, also known as brown spots, are a common skin condition that can be caused by various factors such as sun exposure, aging, and genetics. Recognizing the causes and symptoms of age spots is essential to seek appropriate medical care when necessary.
