Q-switch Nd-Yag laser is a specialised laser treatment that utilises a specific type of laser called Nd-Yag. The "Q-switch" refers to the technology used to deliver short, high-energy pulses of laser light. These pulses are specifically designed to target and fragment pigmented cells in the skin, without causing damage to the surrounding tissue. The power of laser energy is harnessed in this non-invasive procedure to target and break down unwanted pigmentation, such as freckles, sunspots,melasma and birthmarks.
