Background:
Rosacea is a common skin condition, but the currently available treatments are not satisfactory.
Objective:
We wanted to assess the efficacy and safety of photopneumatic therapy (PPx), which delivers pneumatic energy and broadband light (400~1,200 nm), for the treatment of erythematotelangiectatic rosacea.
Methods:
Twenty two patients with erythematotelangiectatic rosacea were treated 3~5 times with PPx. Three independent dermatologists evaluated the efficacy of PPx by comparing the photographs taken before and after treatment. Patient self-assessment was also done by interviews.
Results:
The photographic assessment by the dermatologists of the improvement showed that >50% improvement occurred in 64% (14/22) of the patients. The specific categories of improvement were as follows: poor (<25% improvement), 1 patient; fair (25~50% improvement), 7 patients; good (50~75% improvement), 11 patients; and excellent (>75% improvement), 3 patients. Based on the patients' self-assessment, 20 patients (91%) acknowledged an improvement.
Conclusion:
PPx is an effective and safe treatment option for erythematotelangiectatic rosacea.
