Which type of laser is recognized as effective for the treatment of keloids?

The pulsed dye laser is recognized as effective for the treatment of keloids due to its specific wavelength that targets blood vessels within the keloid tissue. When the pulsed dye laser is applied, it emits a yellow light that is absorbed by the hemoglobin in the blood vessels, leading to photocoagulation and subsequent reduction in the vascularity and associated redness of keloids. This results in a flattening effect on the keloid, improving its appearance.

Moreover, the pulsed dye laser also promotes collagen remodeling in the treated area, which can help in reducing the overall size and texture of keloids over time. This dual effect of targeting both vascular components and stimulating collagen production makes the pulsed dye laser a preferred option for keloid treatment.

In contrast, while other lasers such as carbon dioxide, erbium, and Nd:YAG can also be utilized in dermatological procedures, they may not specifically address the characteristics of keloids as effectively as the pulsed dye laser. For example, carbon dioxide lasers are more aggressive and can cause significant tissue removal, which may not be ideal for keloids as it can sometimes lead to further scarring or worsen the condition. Similarly, erbium lasers are often used
