Black Spots on Lips: Causes, Risks, and Care Tips

Black spots on the lips?

I recently noticed light-colored black spots on my lips (four on the lower lip, one on the upper right lip, none inside the mouth, and no dense moles elsewhere on my body).
After seeing a doctor, I was informed that my black spots are symmetrically distributed, and the doctor believes they are moles.
I would like to ask: is it normal to have so many moles on the lips? Is there a high risk of malignancy for moles on the lips? (I am very concerned about melanoma.) Could the appearance of black spots on my lips be related to my long-term lip dryness? Could using mint products (similar to Mentholatum) cause black spots on my lips? Additionally, I noticed that the black spot on my upper right lip has a color distribution of a light ring around it with a small, darker center.
On one occasion, when my lips were peeling, I found a piece of skin that had a black spot on it, seemingly from the area of the darker spot.
That darker spot is still there but has become smaller.
Is it possible that after peeling, that black spot will disappear? Or should I pay more attention to this black spot on my upper right lip? Thank you very much for taking the time to respond, and I wish you well!

Medical regulations state that "physicians must personally examine patients before providing treatment or prescribing medications," and therefore, online diagnosis is not permitted.
If you are experiencing significant distress, it is advisable to seek medical attention promptly.

More Info

Understanding black spots on the lips can be a source of concern for many individuals, especially when they appear suddenly or change in appearance. Based on your description, it seems you have noticed several small black spots on your lips, which have been assessed by a physician as symmetrical and likely benign moles (nevi). Here’s a comprehensive overview of the potential causes, risks, and care tips regarding these black spots.

Causes of Black Spots on the Lips
1. Benign Moles (Nevi): The spots you described could simply be benign moles. These are common and can appear anywhere on the body, including the lips. They are usually harmless and do not require treatment unless they change in size, shape, or color.

2. Hyperpigmentation: This can occur due to various factors, including sun exposure, hormonal changes, or skin irritation. Chronic dryness of the lips, as you mentioned, could lead to increased pigmentation as the skin reacts to irritation.

3. Melanosis: This condition involves the darkening of the skin due to an increase in melanin production. It can be caused by factors such as sun exposure or certain medications.

4. Irritation from Products: Using products like mentholated lip balms can sometimes cause irritation or allergic reactions, leading to changes in pigmentation. If you suspect that a product is causing your lips to darken, consider discontinuing its use and observing any changes.

5. Trauma or Injury: If you have experienced any trauma to your lips, such as biting or excessive peeling, this could lead to localized hyperpigmentation as the skin heals.

Risks of Black Spots on the Lips
While most black spots on the lips are benign, it’s essential to monitor them for any changes. The risk of malignancy, such as melanoma, is generally low for moles that are symmetrical and uniform in color. However, you should be vigilant for the following warning signs:
- Asymmetry: If one half of the mole does not match the other.

- Irregular Borders: If the edges are not smooth or are ragged.

- Color Variation: If there are multiple colors within the mole.

- Diameter: If the mole is larger than 6mm (about the size of a pencil eraser).

- Evolving: If the mole changes in size, shape, or color over time.

Care Tips
1. Moisturize: Keep your lips hydrated with a good quality lip balm that is free from irritating ingredients. Look for products that contain natural oils or butters.

2. Sun Protection: Use lip balms with SPF to protect your lips from UV damage, which can exacerbate pigmentation issues.

3. Avoid Irritants: If you suspect that certain products are causing irritation, discontinue their use and consult with a dermatologist for alternatives.

4. Monitor Changes: Keep an eye on the black spots for any changes in appearance. If you notice any concerning changes, consult a dermatologist for further evaluation.

5. Consult a Dermatologist: If you have persistent concerns about the spots, especially the one that has changed in color or size, it’s advisable to seek a professional opinion. A dermatologist can perform a thorough examination and may recommend a biopsy if there are any suspicious features.

Conclusion
In summary, while the presence of black spots on the lips can be concerning, many are benign and do not pose significant health risks. However, it is crucial to monitor these spots for any changes and maintain good lip care practices. If you have any doubts or notice any alarming changes, don’t hesitate to consult a healthcare professional for peace of mind and appropriate management.

We need to take a look! Since I can't see the situation right now, it could be due to post-inflammatory hyperpigmentation, possibly caused by an allergic reaction to toothpaste or lip balm. A proper examination is necessary to make a diagnosis.
