TRASER Effective for Telangiectasia

An experimental device that offers multiple tunable wavelengths—the TRASER (Total Reflection Amplification of Spontaneous Emission Radiation)—is safe and effective in the treatment of nasal telangiectasias, according to a study published in Lasers in Surgery and Medicine (August 2017).

Paul M. Friedman, MD, et al, treated 15, Fitzpatrick skin type I and II subjects (aged 42–73) for nasal telangiectasias of various sizes. The TRASER was tuned to produce a narrow spectral output peaking at 541 +/- 5nm with 20ms to 40ms pulse widths. Blinded analysis of pre- and post-images (30 days following treatment) and subject self-assessment were used to measure efficacy.

The 13 subjects who completed the study all achieved a 2-point improvement of telangiectasis on the 5-point Telangiectasia Scale and >75% of patients had at least a 75% reduction in blood vessels. The researchers noted that larger vessels required a longer pulse duration (40ms); smaller vessels responded best to shorter pulse durations (25ms), and no serious adverse events were recorded.
