Question: 1 / 400

Which laser has the deepest penetration depth?

Ruby

Alex

Diode

Nd:YAG

Nd:YAG laser has the deepest penetration depth compared to the other laser options listed. This is because Nd:YAG lasers have longer wavelengths (1064nm), allowing them to penetrate deeper into the skin while targeting the hair follicles. Ruby, Alex, and Diode lasers have shorter wavelengths, which limit their penetration depth compared to the Nd:YAG laser.
