简要总结

The goal of this clinical trial is to learn if fractional ablative laser can treat active acne vulgaris in adults 18 to 40 years old with moderate to severe acne vulgaris.

The main questions it aims to answer are:

Does ablative fractional carbon dioxide treatment effectively treat moderate to severe active nodular acne vulgaris?

Does ablative fractional carbon dioxide treatment effectively treat moderate to severe active nodular acne vulgaris over a short time frame?

Is non-selective laser useful in treating inflammatory skin disease?

How does the microbiome change after laser treatment?

Participants will...

  • Receive up to 3 laser treatments
  • Attend a baseline visit and follow-up visits post-treatment where participants will receive a clinical assessment, facial swab, and facial-imaging

详细描述

This study is designed to evaluate the efficacy of ablative fractional laser treatment for the clinical improvement or treatment of active acne vulgaris. We will be performing a self-controlled study, where each eligible subject will serve as their own control. Each subject will receive an ablative fractional 10,600 nm carbon dioxide laser treatment (Lumenis® Ultrapulse® C02 laser with DeepFX™ Yokneam, Israel).

There is another arm in the study. 22 subjects with acne will be selected to do the same laser treatment on a localized part of the face (1-3 inflammatory lesions and up to 5 mm adjacent area).

We plan to have 22 subjects complete the study on the first arm and 22 on the second arm. Both arms will be treated with the same device and the same energy and density will be used. The first arm will be submitted to 3 laser treatments, with a one-month interval between each treatment appointment and their full face will be treated. The second arm will have only one treatment and only 1-3 lesions will be submitted to the laser treatment.

结局指标

主要结局

Changes in Physician's Global Assessment (PGA) of Acne Severity

时间窗: Change in PGA score between baseline visit and post procedural visit

The physician will score the acne vulgaris based on the Physician's Global Assessment (PGA) scale. A score of 0 indicates that residual hyperpigmentation and erythema may be present; a score of 1 indicates that there are a few scattered comedones and a few small papules; a score of 3 indicates that more than half of the face is involved, that there are many comedones, papules, and pustules, and that one nodule may be present; a score of 4 indicates that the entire face is involved, covered with comedones, numerous papules and pustules, and a few nodules and cysts. The change in PGA score will be recorded at each of the 4 study visits, for up to
