Which laser is the best to treat port wine stain, yag laser or v-beam? Or is there a better alternative?

Port wine stains are capillary malformations which means they are composed of vessels of varying sizes and depth in the skin.  Most do quite well with the pulsed dye laser (v-beam).  Occasionally, one might hit a plateau with the pulsed dye laser and may need to use a deeper penetrating laser like the Nd-Yag.  The most important thing to understand is that multiple treatments (4-15) may be necessary and sometimes the best that can be achieved is significant reduction in the port wine stain but not resolution.  Good luck

I like the yellow laser the best but pulsed dye or excel V are good alternatives. IPL can work but often has higher recurrence rates. Best, Dr. Emer.

Traditionally, the VBeam®, or pulsed-dye-laser, has been considered the standard treatment for port-wine stains. However, the recent medical literature is now showing many studies where Nd:Yag laser (in combination with pulsed-dye laser, or not) is effective in larger or deeper port-wine stains. Please consult a board certified aesthetic dermatologist for a consultation.
