Unusual Lip Color Changes: Causes and Solutions

The color of the lips is different from others?

Hello Doctor: My lips, as shown in the linked photo (https://img.onl/el2H6z), are usually a purplish-black color, similar to the character Fujiki from "Chibi Maruko-chan." I didn't have this discoloration during infancy, but it developed as I grew older.
Is it possible for lips to get darker from sun exposure? During elementary school, I didn't use sunscreen and my skin became very dark, but now my overall skin tone has returned to normal while my lips remain unchanged.
Additionally, when I'm feeling unwell, the color of my lips becomes even darker.
I have mitral valve prolapse without mitral regurgitation and mild tricuspid regurgitation; could this affect my lip color? Are there other possible causes? I'm unsure if there are ways to return my lips to a normal color, as they appear quite concerning, almost like poisoning.
If medical attention is necessary, which specialty should I consult? Thank you, Doctor.

Hello, based on your photo, the color of your lips is only slightly darker but still within the normal range.
Mitral valve prolapse and tricuspid regurgitation can indeed cause hypoxia, which may lead to darker lip color; however, if you do not experience shortness of breath, it is unlikely that you are hypoxic.
I recommend visiting a cardiology clinic to check for any hypoxic conditions.
If there are none, it indicates that there is no physiological disease.
If you still wish to lighten your lips, you should consult a dermatologist or a plastic surgeon for cosmetic treatment.
Thank you for your inquiry.

More Info

Unusual lip color changes can be concerning and may arise from various underlying causes. In your case, the persistent dark purple or blackish hue of your lips, especially when it contrasts with your overall skin tone, warrants a closer examination. Here are some potential reasons for these changes and suggestions for addressing them.

Possible Causes of Unusual Lip Color
1. Hyperpigmentation: This is a common cause of darkened lips. Factors such as sun exposure, hormonal changes, or certain medications can lead to increased melanin production in the skin, including the lips. While you mentioned that your lips did not exhibit this color during infancy, it is possible for hyperpigmentation to develop later in life due to cumulative sun exposure, especially if you did not use sun protection as a child.

2. Circulatory Issues: Your heart condition, specifically mitral valve prolapse and mild tricuspid regurgitation, could potentially affect blood flow. Poor circulation can lead to cyanosis, where lips may appear bluish or darker due to insufficient oxygenation. If your lips darken when you feel unwell, this could be indicative of circulatory changes or oxygen deprivation.

3. Dehydration and Dryness: Dehydrated or chapped lips can appear darker. Factors such as dry weather, lack of hydration, or certain habits (like licking your lips) can exacerbate this condition.

4. Allergic Reactions or Irritation: Certain lip products, food allergies, or irritants can cause discoloration. If you have recently changed your lip care products or have been exposed to new foods, this could be a contributing factor.

5. Medical Conditions: Other medical conditions, such as certain skin disorders or systemic diseases, can lead to changes in lip color. Conditions like Addison's disease or other endocrine disorders can also manifest through skin and lip pigmentation changes.

Solutions and Recommendations
1. Consult a Healthcare Professional: Given the complexity of your symptoms and the potential underlying causes, it is advisable to consult a healthcare professional. A dermatologist would be the most appropriate specialist to evaluate your lip color changes, as they can assess for skin conditions, hyperpigmentation, or other dermatological issues. If there are concerns about your heart condition affecting your circulation, a cardiologist may also be involved.

2. Sun Protection: If sun exposure is a contributing factor, using a lip balm with SPF can help protect your lips from further darkening. This is especially important if you spend time outdoors.

3. Hydration: Ensure you are adequately hydrated. Drinking plenty of water and using moisturizing lip products can help improve the appearance of your lips.

4. Avoid Irritants: If you suspect that certain products may be causing irritation, consider eliminating them from your routine. Opt for hypoallergenic and fragrance-free lip products.

5. Topical Treatments: Depending on the diagnosis, dermatologists may recommend topical treatments such as hydroquinone or retinoids to address hyperpigmentation. However, these should only be used under medical supervision.

6. Lifestyle Modifications: Maintaining a healthy diet rich in vitamins and antioxidants can support skin health. Foods high in vitamin C, E, and omega-3 fatty acids can be beneficial.

Conclusion
In summary, the dark coloration of your lips could stem from various factors, including hyperpigmentation, circulatory issues, or external irritants. It is essential to seek a professional evaluation to determine the exact cause and appropriate treatment. A dermatologist will be able to provide a thorough assessment and recommend suitable interventions to help restore your lips to a more typical color. Remember, taking proactive steps in skincare and consulting with healthcare professionals can significantly improve your situation.
