Copper bromide laser for facial telangiectasia: a dose response evaluation.

Facial telangiectases are small dilated vessels that are visible on the skin surface. They are a cosmetic disfigurement for millions of people, making their treatment one of the most frequently requested procedures in dermatology. Several treatment choices are available, including a variety of lasers. The purpose of this study was to evaluate the results, using a copper bromide laser, of variable energy levels related to vessel size and location, including side effects, and to survey patient assessment of benefit and tolerance. Two groups of 19 patients were treated at 23 J/cm(2) and 28 J/cm(2) , and 32 J/cm(2) and 38 J/cm(2) , respectively. Only facial telangiectasias were treated. Benefit was seen at all energy settings. Little additional benefit was noted with energy increase alone, but it was noted with a second treatment. This study showed that the copper bromide laser is a very effective, safe, and well tolerated treatment for facial telangiectasia at all four tested energy levels.
