The Q-Switched Nd:YAG Laser is an advanced medical device originally designed to treat skin pigmentation issues, melasma, and tattoo removal. In recent years, it has also proven to be highly effective in reducing fine and vellus hair — the light, thin hair that traditional laser systems often struggle to target.

The Q-Switch works by emitting high-energy, ultra-short light pulses (in nanoseconds) that break down pigment particles or affect delicate hair follicles without damaging the surrounding skin.
