Brown spots, freckles, and tattoos can be removed with the non-invasive Q-switched laser. Pigmentation irregularities are corrected using a billionth-of-a-second laser pulse that does not harm the surrounding tissue. At the point when the extreme focus beats light emission coordinated towards the shade, it retains the laser energy and breaks down so the body can normally discard the waste colour. To significantly reduce pigmentation, the Q-switched laser penetrates the skin’s deeper layers.
