IPL with collagen dressings shows higher efficacy than dressings alone for facial postburn hyperpigmentation
A randomized controlled trial evaluated intense pulsed light (IPL) combined with collagen wound dressings versus collagen dressings alone in 90 patients with facial hyperpigmentation from second-degree burns. The primary outcome was efficacy rate at 3 months, with secondary outcomes including reduction in hyperpigmentation area/intensity, VISIA skin analysis scores, patient satisfaction, and anxiety/depression scores (SAS and SDS).
The combination therapy group (IPL plus dressings) showed a significantly higher efficacy rate of 95.1% compared to 61.5% in the control group (dressings alone), with a p-value < 0.05. Reductions in hyperpigmentation area and intensity, improvements in VISIA analysis parameters (spots, UV spots, brown spots), patient satisfaction scores, and psychological scores were all significantly greater in the combination group, with all comparisons reporting p < 0.05. Exact numerical reductions and effect sizes were not reported.
The intervention was described as safe with minimal side effects, though serious adverse events were not reported. Of the 90 enrolled patients, 80 completed the study, indicating 10 discontinuations. Key limitations include the lack of reported absolute numbers, effect sizes, study phase, setting, and funding/conflict of interest details. While the results are promising for this specific postburn population, the restrained practice relevance is that combination therapy may offer superior outcomes to dressings alone, but the evidence requires confirmation in larger, more detailed studies.
