Clinical Observation on the Treatment of Acne Vulgaris with Different Pulse Numbers of ACNE Filters Using Intense Plused Light
Objective To investigate the therapeutic efficacy and safety of different pulse numbers of ACNE filters using intense pulsed light(IPL)in the treatment of acne vulgaris.Methods Thirty patients with acne vulgaris who attended the outpatient department of Medical Cosmetology at the author's hospital between August 2023 and October 2023 were included according to specific screening criteria.A self-controlled experimental design was used,with the left and right sides of each patient's face randomly assigned to either a triple-pulse treatment side or a double-pulse treatment side using the random number table method.The ACNE filters were applied to the acne areas on both sides of the face during each treatment session,with identical energy density,pulse delay,and sub-pulse width.The only difference between the two sides was the number of pulses.The triple-pulse side was treated with 4 ms-4 ms-4 ms pulses,while the double-pulse side was treated with 4 ms-4 ms pulses.Additional filters were subsequently used to treat the entire face,with uniform parameters on both sides.Treatments were conducted once every 4 weeks for a total of 3 sessions.Treatment efficacy was evaluated and compared between the two sides at 4 weeks after each session,and adverse events were documented during each treatment and follow-up period.Results The triple-pulse treatment side showed significantly better outcomes than the double-pulse side in terms of total acne count,efficacy index,number of inflammatory acne lesions,efficacy index of inflammatory acne,total effective rate,and significant efficacy rate.There was no significant difference between the two sides in the number and efficacy index of non-inflammatory acne.Regarding safety,one patient in the double-pulse treatment group developed patchy scabs and blisters on the forehead after treatment,while no significant adverse events were observed on the triple-pulse treatment side.Conclusion When using IPL with ACNE filters for the treatment of acne vulgaris,the 4 ms-4 ms-4 ms triple-pulse setting may be a more effective parameter compared to the 4 ms-4 ms double-pulse setting.
