How the treatment works
The laser delivers energy at a specific wavelength, chosen because water and the pigment in soft tissue absorb it readily. The energy is taken up by the target and dissipates quickly rather than travelling into the surrounding area, so it vaporises tissue in a thin, precise layer.
Small blood vessels at the margin tend to be sealed as the laser passes, so bleeding is usually reduced and sutures are often unnecessary. Nerve endings at the surface are affected in the same way, which is why some patients report less sensitivity immediately after treatment. Neither effect removes the need for anaesthetic in every case.
