Protocol summary

Study aim
Comparison of the efficacy and safety of PDL, IPL and long pulse Nd:Yag 1064 laser in the treatment of mild to moderate inflammatory acne vulgaris
Design
A three-arm , parallel-group, without control group, single-blind, randomized, phase 2 clinical trial on 36 patients.
Settings and conduct
The diagnosis is made in the dermatology clinic of Rasool Akram Hospital. Then, the eligible patients are randomly divided into three groups for laser treatment through the selection of non-transparent envelopes, in order to blind the patients to the choice of treatment modality. The first group is treated with a PDL laser with a wavelength of 585 nm, a spot diameter of 7 mm, a fluence of 3 J, and a pulse duration of 350 microseconds. In the second group, patients under treatment with IPL laser with a wavelength of 240-1200 nm and a fluence of 7 J, and in the third group of patients under treatment with a Nd:Yag long pulse laser with a wavelength of 1064 nm and a pulse duration of 40 microseconds and with a fluence of 40 J. Patients are treated with laser in 3 sessions at an interval of 2 weeks in the dermatology clinic of Hazrat Fatemeh Hospital.
Participants/Inclusion and exclusion criteria
Participants over 18 years old with mild to moderate facial inflammatory acne Not taking isotretinoin in the last 6 months. Patient satisfaction No history of hypertrophic scar or keloid Not taking anticoagulant drug in the last 2 months No Pregnancy or breastfeeding No history of Photosensitivity and rheumatologic diseases
Intervention groups
The study does not have a control group. In the first group of patients, three sessions of PDL laser will be treated. In the second group, three sessions of IPL laser will be treated, and in the third group of patients, three sessions of Nd:YAG laser will be treated.
Main outcome variables
Severity of acne lesions, The number of acne lesions, Quality of life

General information

Reason for update
Due to the lack of long pulse mode on the Nd:YAG device available at the laser center, another mode of the same wavelength, the Q-switch form, has been used.
