What is the reason that argon laser is recommended for use in vascular lesions?

The recommendation of the argon laser for use in vascular lesions primarily rests on its high absorption by hemoglobin. This characteristic makes the argon laser particularly effective for targeting vascular lesions, as hemoglobin is the primary chromophore in blood. When the laser light is absorbed by hemoglobin, it leads to photocoagulation of the blood vessels, thus effectively treating conditions like telangiectasia, hemangiomas, and other vascular anomalies.

The efficiency of this laser in selectively targeting hemoglobin minimizes collateral damage to surrounding tissues, making the treatment not only effective but also safer, as healthier cells are preserved during the procedure. Unlike options that suggest attributes such as deep tissue penetration or adaptability to different skin types, the key benefit lies in its distinct affinity for hemoglobin, providing precise treatment for vascular lesions while minimizing risks associated with thermal damage to adjacent non-vascular structures.
