Brief Summary
This study is being done to compare a new, continuous illumination and short Incubation time regimen of aminolevulinic acid photodynamic therapy#ALA- PDT) to a conventional regimen for treatment of Moderate or Severe Acne. The hypothesis is that the continuous illumination approach will be less or even no painful, but equally efficacious, as the old regimen.

Study Arms (2)
Painless Photodynamic Therapy(P-PDT) group
EXPERIMENTALThe painless photodynamic therapy group underwent narrow-band light-emitting diode (LED) irradiation (630 nm; 150 J/cm2) after applying 5% 5-aminolevulinic acid#ALA#cream for 30min. A repeat treatment was administered once weekly for a maximum of 3 weeks.
Conventional Photodynamic Therapy(C-PDT) group
ACTIVE COMPARATORThe conventional photodynamic therapy(C-PDT) group underwent narrow-band light-emitting diode (LED) irradiation (630 nm; 50 J/cm2) after applying 5% 5-aminolevulinic acid cream for 1.5h.A repeat treatment was administered once weekly for a maximum of 3 weeks.
Interventions
