In this study the investigators aim to optimize Port-Wine-Birthmark (PBW) laser therapy in children in order to reduce the number of laser treatments required for clearance and improve outcomes for refractory cases. This approach also seeks to reduce the frequency with which children require general anesthesia for treatment.

Change in Port Wine Birthmark (PWB) color in participants - Pre Operative
Prior to treatment, the PWB will be documented photographically. Images taken will be transformed in to the L a\*b\* colorspace (also known as the red green color axis), and regions of interest defined on the photographs corresponding with the areas treated by each modality, as well as a region of interest adjacent to the treated area, to act as a control to correct for skin changes unrelated to the treatment. The axis is representative of color chromaticity and is measured in a range of -128 to 127. Positive values are indicative of red, and negative values are indicative of green. The quantitative values of the a\* channel in the L a\*b\* colorspace will be used as a measure of the PWB intensity and each treated area will be compared with the corresponding area pre-treatment, using the difference in a\* values to determine the treatment effectiveness.

Change in Port Wine Birthmark (PWB) color in participants - Post Operative
Post-operatively, the treated area will once more be documented photographically. Images taken will be transformed in to the L a\*b\* colorspace (also known as the red green color axis), and regions of interest defined on the photographs corresponding with the areas treated by each modality, as well as a region of interest adjacent to the treated area, to act as a control to correct for skin changes unrelated to the treatment. The axis is representative of color chromaticity and is measured in a range of -128 to 127. Positive values are indicative of red, and negative values are indicative of green. The quantitative values of the a\* channel in the L a\*b\* colorspace will be used as a measure of the PWB intensity and each treated area will be compared with the corresponding area pre-treatment, using the difference in a\* values to determine the treatment effectiveness.
6 weeks
Every patient will receive the 5 treatment modalities in their first laser treatment after enrollment in the study. * At 5-7 weeks follow-up visit after the procedure, if no treatment modality is better than the other, then the surgeon will repeat the procedure with the 5 modalities, and the subject will have a 2nd follow-up appointment 5-7 weeks later. Continue treatment with 5 modalities and appropriate follow-up until Port Wine Birthmark (PWB) clearance, or, * If any modality is seen to give best results at the first follow-up visit (5-7 weeks after the first procedure), then the next treatment will be only with that modality and will continue to have treatments with this modality and follow-up appointments (5-7 weeks after procedure) according to standard of care timelines for PWBs until the treatment is not improving the PWB anymore or until the PWB is no longer visible.
Pulse Dye Laser (PDL) standard settings. This is the same procedure children would receive as standard of care if these individuals were not participating in this study. The surgeon will perform 1 pass with the PDL over the area of the Port wine birthmark (PWB).
This procedure is used for some patients as standard of care depending on the severity and depth of the lesion. The surgeon will perform 3 passes with the PDL over the PWB, gradually increasing the pulse duration with each pass to effectively target both superficial and deeper blood vessels.

Personalized Interactive Laser Therapy of Port Wine Stain
The combination of these two lasers is one of the investigational treatments. The surgeon will perform 1 pass per laser over the PWB. The 1st pass will be with the PDL to target the blood vessels closer to the top of the skin, followed by a 2nd pass with the Nd:YAG laser to target the blood vessels that deeper in the skin.
The surgeon will perform 1 pass with the IPL followed by 1 pass with the PDL over the PWB
The combination of these modalities is one of the experimental procedures. The surgeon will place a small suction cup over the PWB target region of the PDL for a few seconds to stop the blood flow and accumulate the blood in that spot. The PDL treatment will then quickly proceed. Since the PDL targets red blood cells, it will allow the laser to target the pooled blood in the abnormal blood vessels better.
