Darkened Skin: Is It a Pigmentation Issue? - Dermatology

Pigmented lesions?


Hello Dr.
Cheng, the skin between my lower lip and chin appears darker than the rest of my face, almost as if it has been excessively sun-exposed.
This has persisted for nearly a year, but I do not experience any itching or discomfort.
Could this be a pigmentation spot? What methods are available to eliminate it? Is it possible that this could be a sign of another condition? I hope you can clarify this for me.
Thank you.
Sincerely, Xiao Jun.

More Info


Hello, 小君. Thank you for your question regarding the darkened skin between your lower lip and chin. Based on your description, it sounds like you may be experiencing a form of hyperpigmentation, which is a common skin condition characterized by darkened patches of skin. This can occur for various reasons, including sun exposure, hormonal changes, skin irritation, or even certain medications.


Understanding Hyperpigmentation
Hyperpigmentation occurs when excess melanin, the pigment that gives skin its color, is produced in certain areas of the skin. This can result from several factors:
1. Sun Exposure: Prolonged exposure to UV rays can lead to sunspots or areas of increased pigmentation. Even if you don't feel discomfort, UV damage can still affect the skin.

2. Post-Inflammatory Hyperpigmentation: If there was any previous irritation or injury to the skin in that area, it could lead to darkening as the skin heals.

3. Hormonal Changes: Conditions such as melasma, which is often triggered by hormonal changes (like pregnancy or birth control), can cause dark patches on the face.

4. Genetics: Some individuals are more prone to hyperpigmentation due to their genetic makeup.

5. Skin Conditions: Certain skin conditions, such as eczema or psoriasis, can also lead to darkened skin after inflammation subsides.


Diagnosis and Treatment
To determine the exact cause of your darkened skin, it is essential to consult with a dermatologist. They can perform a thorough examination and may recommend tests if necessary. Here are some common treatment options for hyperpigmentation:
1. Topical Treatments: Over-the-counter or prescription creams containing ingredients like hydroquinone, retinoids, vitamin C, or azelaic acid can help lighten dark spots.

2. Chemical Peels: These treatments involve applying a chemical solution to exfoliate the top layers of skin, promoting new skin growth and reducing pigmentation.

3. Laser Therapy: Laser treatments can target specific areas of pigmentation and are often effective for more stubborn cases.

4. Sun Protection: Regardless of the treatment you choose, protecting your skin from further sun exposure is crucial. Use a broad-spectrum sunscreen with at least SPF 30 daily, even on cloudy days.

5. Lifestyle Changes: Maintaining a healthy skincare routine, including gentle cleansing and moisturizing, can help improve overall skin health and appearance.


When to Seek Further Evaluation
While hyperpigmentation is usually benign, it is essential to monitor any changes in your skin. If you notice any of the following, seek medical advice promptly:
- Rapid changes in the size, shape, or color of the darkened area.

- New symptoms such as itching, pain, or bleeding.

- The appearance of other unusual skin lesions.

In conclusion, while the darkened area on your skin may likely be a pigmentation issue, it is essential to consult a dermatologist for a proper diagnosis and treatment plan. They can provide personalized recommendations based on your specific condition and skin type. Thank you for your question, and I hope this information helps you understand your skin better!
