What Is a Q-switch Laser?
A Q-switched laser delivers very short, high-intensity pulses of light — nanoseconds long. At that pulse duration the laser energy fragments pigment particles without heating the surrounding skin. On Indian skin (Fitzpatrick III–VI) this is the safest laser technology for pigmentation work.
The version we use at Uncover is Q-switched Nd:YAG 1064nm. That specific wavelength has low affinity for melanin in the top skin layers and high affinity for pigment in the deeper layers — exactly what pigmented skin needs to clear pigmentation safely.
