Effective Treatments for Keloids: Laser, Steroids, and More - Dermatology

More Info

Keloids, or hypertrophic scars, are raised areas of scar tissue that develop at the site of an injury or incision. They can be itchy, painful, and cosmetically concerning for many individuals. The treatment of keloids can be challenging, and various methods have been employed to manage them effectively. Here, I will discuss some of the most common treatment options, including laser therapy, steroid injections, and other modalities.

1. Steroid Injections: One of the most common treatments for keloids is the injection of corticosteroids directly into the keloid tissue. Steroids help to reduce inflammation and can flatten the keloid over time. This treatment is often repeated every few weeks, and while it can be effective, it may not completely eliminate the keloid. Side effects can include skin thinning and changes in pigmentation.

2. Laser Therapy: Laser treatments, particularly pulsed dye lasers and fractional lasers, have gained popularity for treating keloids. These lasers work by targeting the blood vessels within the keloid, reducing redness and promoting a more even skin texture. Laser therapy can be used alone or in combination with other treatments, such as steroid injections, to enhance results. Multiple sessions may be required, and while laser therapy can improve the appearance of keloids, it may not completely remove them.

3. Surgical Excision: In some cases, surgical removal of the keloid may be considered. However, this approach carries the risk of recurrence, as keloids can grow back after excision. To minimize this risk, surgeons often combine excision with other treatments, such as steroid injections or radiation therapy, immediately following surgery.

4. Cryotherapy: This involves freezing the keloid with liquid nitrogen, which can help to reduce its size. Cryotherapy is often used in conjunction with other treatments, such as steroid injections, for better results.

5. Silicone Gel Sheets: These are applied to the keloid and can help flatten and soften the scar over time. Silicone sheets are a non-invasive option and can be used in conjunction with other treatments.

6. Radiation Therapy: This is sometimes used after surgical excision to prevent recurrence. It is typically reserved for larger keloids or those that have recurred after previous treatments.

7. Topical Treatments: Some over-the-counter topical treatments, such as silicone gels or ointments, may help improve the appearance of keloids, although their effectiveness can vary.

8. Other Options: Emerging treatments, such as 5-fluorouracil injections, imiquimod cream, and even newer biological agents, are being studied for their effectiveness in treating keloids.

Regarding your specific question about using "樂得美" (likely referring to a topical treatment or a specific brand), it's essential to consult with a dermatologist or healthcare provider to determine the appropriateness of any product for your keloid treatment. They can provide personalized recommendations based on your medical history and the characteristics of your keloid.

In conclusion, the treatment of keloids often requires a multifaceted approach tailored to the individual. While no single treatment guarantees complete resolution, combining therapies can lead to improved outcomes. Always consult with a qualified healthcare professional to discuss the best treatment options for your specific situation.
