Tolerability of 532 nm Laser Treatment of Port Wine Stains

Recruiting now · Not applicable

Conditions studied: Port-Wine Stain

In brief

The goal of this study is to learn about treatment of port wine birthmarks treated with an FDA-approved 532 nm laser. The main questions it aims to answer are: * How well are the treatments tolerated? * Are there differences in tolerability of the treatment when a single high fluence laser pulse is used (the standard treatment) versus using multiple low fluence pulses? * Are there differences in results when using a single high fluence pulse versus multiple low fluence pulses? type of study: Clinical Trial Participants will undergo 3 monthly laser treatments with the 532 nm DermaV laser. Part of their birthmark will be treated with the standard single-pulse high fluence approach, and other parts will be treated with the multiple-pulse low fluence approach.
