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.
