Vascular Laser

Vascular lasers emit wavelengths that are preferentially absorbed by haemoglobin.  Laser energy will cause the problematic blood vessels to shut down or burst when absorbed by the targeted structure (haemoglobin) without affecting the surrounding tissue.

Lasers that could target vascular problems include pulsed dye laser (595nm, 585nm), 532nm Nd:YAG long pulse laser and 1064nm Nd:YAG long pulse laser.

 

Common Vascular Problems that Respond Well to Vascular Laser:

  • Rosacea
  • Angioma/ Haemangioma
  • Talengiectasia
  • Port Wine Stain (Vascular Malformation)

 

Procedure

Topical anaesthetic may be applied but usually not necessary.  Each pulse of the laser feels like snapping of a rubber band against the skin. You may experience swelling and redness for few days after the laser, or even bruising depending the energy level determined by the doctor according to the indications for such treatment. Sometimes several sessions of laser may be needed.

During the course of treatment make sure you stay out of the sun or have sufficient sun protection to avoid possible post inflammatory hyperpigmentation (marks). Very rarely blisters or bacterial infection may happen.
