What does the Nd:YAG laser primarily target?

The Nd:YAG laser is primarily targeted at deep tissues, making it particularly effective for treating various vascular lesions and for tattoo removal. This laser operates at a wavelength of 1064 nm, which allows it to penetrate the skin more deeply compared to other lasers. This deep penetration is crucial for targeting deeper structures such as blood vessels, which is why it's commonly used in procedures aimed at treating conditions like hemangiomas and other vascular lesions.

Moreover, when it comes to tattoo removal, the Nd:YAG laser's capability to reach deeper layers of the skin allows it to effectively break down the ink particles that are located below the surface. The energy emitted by the Nd:YAG laser is absorbed by the pigment in the tattoo, facilitating its breakdown and removal by the body’s immune system.

In contrast, the other options either focus on superficial structures or have a more limited application, which does not align with the primary use of the Nd:YAG laser.
