How do pulsed lasers remove tattoos and treat port-wine stains?

Pulsed lasers are effective for treating skin conditions like tattoos and port-wine stains because they allow for the precise delivery of energy to specific targets with minimal damage to surrounding tissue.12

By tuning the laser to specific wavelengths, practitioners can ensure the light is selectively absorbed by the intended pigment or cellular structure. In the case of port-wine stains—which are dark-red birthmarks—the laser energy targets and destroys the abnormal blood vessels responsible for the discoloration. Similarly, pulsed lasers are used to bleach or remove certain types of tattoos by targeting the ink particles within the skin. This process relies on the ability to control the laser's wavelength and intensity, providing a highly localized treatment that spares healthy skin.12
