Lasers can safely and effectively remove unwanted birthmarks

Facebook X LinkedIn Email
Several studies have shown that it is easier to remove port-wine stain birthmarks when patients are younger. A new study demonstrates that it may be advantageous to use a pulsed-dye laser to do so. Researchers from the Laser & Skin Surgery Center of New York and from St. Luke’s-Roosevelt Hospital Center, also in New York, have reviewed nearly 50 cases of pulsed-dye laser removal of facial port-wine stains on babies. Treatment was performed with a 595-nm V-beam pulsed-dye laser from Candela Corp. of Wayland, Mass., with fluence ranging from 7.75 to 9.5 J/cm2, a 10-mm spot size and 1.5-ms...Read full article

    pulsed-dye laser
    A laser with a gain medium consisting of an organic dye, which is carbon-based. The dye is mixed with a solvent, allowing the molecules to diffuse evenly throughout the liquid. The dye medium is capable of producing a larger range of wavelengths compared to gain mediums composed of gas. Thus, dye lasers are commonly used to obtain high bandwidth in tunable/pulsed lasers.
