Skin Lesions: Answers to Common Concerns About Nevus - Dermatology

More Info

---

Hello! Thank you for your questions regarding nevus, specifically concerning your concerns about the growth, treatment, and management of these skin lesions. Let's address each of your questions in detail.

1. Will the nevus continue to multiply, darken, or enlarge?
Nevi, commonly known as moles, can indeed change over time. Some may darken or enlarge due to various factors, including hormonal changes, sun exposure, or simply the natural aging process. However, not all nevi will behave the same way. It's essential to monitor any changes in size, shape, or color, as these can be indicators of potential issues, including the risk of melanoma. If you notice significant changes, it’s advisable to consult a dermatologist for evaluation.

2. How many sessions of laser treatment are typically required for complete removal?
The number of laser sessions required to treat a nevus can vary widely depending on the size, depth, and type of the lesion. Generally, multiple sessions may be needed, often ranging from 2 to 6 treatments, spaced several weeks apart. The dermatologist will assess your specific case and provide a tailored treatment plan based on the characteristics of your nevus.

3. Will new nevi develop after laser treatment?
Laser treatment can effectively remove existing nevi, but it does not prevent new ones from forming. The development of new nevi is influenced by genetic factors, sun exposure, and other environmental factors. Therefore, even after treatment, it is crucial to practice sun protection and regular skin checks to monitor for any new lesions.

4. What is the duration of the post-laser hyperpigmentation phase?
After laser treatment, it is common to experience a period of hyperpigmentation, where the treated area may appear darker than the surrounding skin. This "post-inflammatory hyperpigmentation" can last from a few weeks to several months, depending on your skin type and how it reacts to the treatment. Proper aftercare, including sun protection, can help minimize this effect.

5. How can I prevent the recurrence of nevi after laser treatment?
While you cannot entirely prevent the formation of new nevi, you can take steps to reduce their likelihood. Here are some recommendations:
- Sun Protection: Use broad-spectrum sunscreen with an SPF of 30 or higher, wear protective clothing, and avoid excessive sun exposure, especially during peak hours.

- Regular Skin Checks: Conduct self-examinations of your skin monthly and schedule regular check-ups with a dermatologist to monitor any changes in existing moles or the appearance of new ones.

- Healthy Lifestyle: Maintain a balanced diet, stay hydrated, and avoid smoking, as these factors can contribute to overall skin health.

In summary, while nevi can change over time, monitoring their characteristics is crucial for early detection of potential issues. Laser treatment can be effective, but it’s important to follow up with your dermatologist for personalized advice and care. Remember, proactive skin care and regular check-ups are key to maintaining healthy skin and addressing any concerns promptly. If you have further questions or need clarification, don’t hesitate to reach out to your healthcare provider. Thank you for your inquiry, and take care!
