RESUMO
BACKGROUND: Rosacea is a difficult-to-manage chronic inflammatory skin condition reported to have a negative psychosocial impact on patients. Novel approaches are sought to target the many signs and symptoms of the condition while also improving the quality of life of patients. OBJECTIVE: We assessed the efficacy of the Kleresca® biophotonic platform (KLOX Technologies Inc., Laval, Canada), which creates fluorescent light energy (FLE), to induce a novel form of photobiomodulation for treating rosacea. We also assessed patient satisfaction with their facial appearance and concerns about perceptions of others before and after treatment. METHODS: Nine patients were treated once a week for four weeks with FLE. Patients and the treating clinician completed questionnaires throughout and after the treatment to grade the rosacea signs and symptoms and capture patients' perceptions of the treatment and their condition. RESULTS: FLE significantly reduced the inflammatory erythematous reaction of the face, improved flushing and erythema associated with rosacea, and had a positive impact on patients' self-perception and emotional wellbeing. CONCLUSION: Our results support FLE as an effective, noninvasive treatment modality for rosacea.
