Ruby Laser Mole Removal: Concerns and Aftercare - Dermatology

More Info

---

Ruby laser treatment for mole removal is a popular procedure, particularly for individuals looking to address skin imperfections such as moles or pigmented lesions. However, as you've experienced, it is not uncommon for patients to notice some unexpected outcomes following the treatment, such as the appearance of post-inflammatory hyperpigmentation (PIH) or darkening around the treated area.

Understanding Post-Procedure Changes
1. Post-Inflammatory Hyperpigmentation (PIH): After laser treatments, especially in individuals with darker skin types, the skin can react by producing excess melanin in response to inflammation. This can manifest as dark spots or patches surrounding the treated area, which may appear larger than the original mole. This phenomenon is particularly common with ruby laser treatments, as they target melanin in the skin.

2. Healing Process: After the scab from the laser treatment falls off, the skin undergoes a healing process. During this time, it is possible for the treated area to appear darker or discolored. In many cases, this discoloration can fade over time, but it may take several weeks to months for the skin to return to its baseline color.
3. Timeframe for Fading: If you choose not to use any topical treatments, the hyperpigmentation may gradually fade on its own, typically within 3 to 6 months. However, the rate at which this occurs can vary significantly based on individual skin types, the depth of the laser treatment, and how well the skin heals.


Treatment Options
If the discoloration persists or if you are concerned about the appearance of the treated area, there are several options to consider:
- Topical Treatments: Your dermatologist may recommend topical agents such as hydroquinone, retinoids, or vitamin C serums to help lighten the hyperpigmentation. These products can promote skin cell turnover and inhibit melanin production.

- Chemical Peels or Additional Laser Treatments: In some cases, dermatologists may suggest chemical peels or additional laser treatments to help even out skin tone and reduce the appearance of dark spots.

- Sun Protection: It's crucial to protect the treated area from sun exposure, as UV rays can exacerbate hyperpigmentation. Using a broad-spectrum sunscreen with an SPF of 30 or higher is essential to prevent further darkening.


Factors Influencing Mole Development
Regarding your question about the increase in moles with age and their relationship with sunlight:
1. Genetics: The number of moles you have can indeed be influenced by genetics. If your family has a history of numerous moles, you may be predisposed to developing more as you age.

2. Age: It is common for individuals to develop new moles throughout their lives, particularly during childhood and adolescence. However, the rate of new mole formation can slow down in adulthood.

3. Sun Exposure: Ultraviolet (UV) radiation from the sun is a significant factor in the development of new moles and changes in existing moles. Prolonged sun exposure can lead to the formation of new pigmented lesions and can also cause existing moles to darken or change in appearance.


Conclusion
In summary, the appearance of darkening around the treated mole after ruby laser treatment is a common occurrence, often related to post-inflammatory hyperpigmentation. While this discoloration can fade over time, there are various treatment options available if it does not improve. Additionally, the development of moles is influenced by genetic factors and sun exposure, making sun protection an essential part of skincare, especially after laser treatments. Always consult with your dermatologist for personalized advice and treatment options tailored to your specific needs.
