  • Brown age spots
  • Dark freckles on the face, lip or body
  • Birth marks such as nevus of Ota and Becker’s nevus
  • Artistic tattoos, especially the black and brown colors
  • Accidental tattoos with lead, gravel etc.
  • Some skin discolorations due to drugs


  • The Q-switched Nd:YAG laser emits 2 wavelengths at 532 and 1064nm.
  • These wavelengths are preferentially absorbed by dark pigment. When the light beam reaches its target, the pigment undergoes a sort of micro explosion. The microscopic debris is then cleared away by macrophages, the skin’s natural scavengers.


  • The skin is cleansed and appropriate eye protection is provided
  • The beam is then aimed at the pigmented lesion in a pulsed mode.
  • Individual lesions do not require local anesthesia.
  • Large areas may require prior application of a numbing cream.
  • Each pulse feels like the snapping of a rubber band.
  • There is an immediate darkening of the lesion following treatment. This is followed by formation of a thin scab which falls off within 1 week for facial and 2 weeks for non-facial treatment areas.
