FLE Treatment
Patients were treated with FLE according to the biophotonic treatment protocol. A thin layer (2 mm) of a topical photoconverter gel was applied to the face with the eyes protected by ocular shields. The gel was subsequently illuminated by a multi-LED lamp delivering non-coherent blue light with a power density of 150 mW/cm2 and an optimized peak wavelength of 440-460nm. Illumination was done at a distance of 5 cm from the skin surface for a duration of 9 min.15-17,57
After each session of illumination, the exhausted photoconverter gel was removed 15,16, and skin moisturizing products for acneic skin was applied. Patients were treated with double FLE treatments (two treatments with a 2 hour break between treatments) once a week for 6 weeks (total of 12 FLE treatments). Double FLE treatments were repeated after 6 and 12 months.
