简要总结
This randomized, single-center, double-blinded, split-face, controlled clinical trial was conducted to investigate the tolerability, safety, and efficacy of a post-procedure cream when used immediately after fractional ablative CO2 laser treatment and for 14 days post-procedure with three times daily application in healthy female subjects aged 35 to 65 with moderate to severe global facial overall photodamage (score of 4 to 9 out of the 10-point Modified Griffiths' scale). Furthermore, this clinical trial compared the active post-procedure cream to a comparator anhydrous formulation often paired with skin rejuvenation procedures. This is a cosmetic study with a FDA-regulated device.
A total of 22 healthy female subjects completed the study.
详细描述
This randomized, single-center, double-blinded, split-face, controlled clinical trial was conducted to investigate the tolerability, safety, and efficacy of a post-procedure cream when used immediately after fractional ablative CO2 laser treatment and for 14 days post-procedure with three times daily application in healthy female subjects aged 35 to 65 with moderate to severe global facial overall photodamage (score of 4 to 9 out of the 10-point Modified Griffiths' scale). The ability of the post-procedure cream to soothe skin and improve patient downtime post-procedure was investigated by evaluating tolerability parameters (erythema, edema, dryness, burning, itching, stinging) and pain over the course of the study. Furthermore, this clinical trial compared the active post-procedure cream to a comparator anhydrous formulation often paired with skin rejuvenation procedures.
A 14-day washout period was required of all subjects prior to CO2 laser treatment. Tolerability (investigator: erythema, edema, dryness; subject: burning, itching, stinging) and safety were assessed through grading at screening, pre-procedure, post-procedure, post-procedure/post-product application, and days 1, 3, 5, 7, and 14 post-procedure. Pain evaluations were completed by subjects using the 11-point Wong Baker Faces® Pain Rating scale post-procedure, post-procedure/post-product application, and days 1, 3, 5, 7, and 14 post-procedure.
In addition, efficacy evaluation using the Modified Griffiths' scale was performed at screening, pre-procedure, and days 1, 3, 5, 7, and 14 post-procedure. Self-assessment questionnaires were completed by subjects post-procedure/post-product application and days 1, 3, and 14 post-procedure. Clinical photography was completed at all timepoints (screening to day 14 post-procedure).
A total of 22 subjects completed study participation.

盲法说明
Subjects were randomly assigned to use the active post-procedure cream on one side of the face and the comparator anhydrous formulation on the opposite side of the face.
The products were packaged in the same container and labelled post-procedure cream. This was a double blinded study, where the investigator, study subject, and other study personnel involved in the evaluation of the efficacy or safety were blinded to group during the study.

结局指标
主要结局
Incidence of Adverse Events
时间窗: 14-days
The primary safety endpoint will be determined by the incidence and severity of adverse events in healthy subjects, including immediately post-procedure and throughout the length of the study.
Investigator Tolerability
时间窗: 14 days
The primary tolerability endpoint will be Investigator Tolerability Assessment of erythema, edema, and dryness. A change in score or lack of significant change post product application, Day 1 (24 hours), Day 3, Day 5, Day 7, and Day 14 in comparison to baseline (immediately post-procedure) indicates tolerability / safety of the test material. A four-point scale will be used with a lower score indicating a better outcome: 0 = None 1. = Mild 2. = Moderate 3. = Severe
Subject Tolerability
时间窗: 14 days
The subject tolerability endpoint will be Subject Tolerability Assessment of burning, itching, and stinging. A change in score or lack of significant change post product application, Day 1 (24 hours), Day 3, Day 5, Day 7, and Day 14 in comparison to baseline (immediately post-procedure) indicates tolerability / safety of the test material. A four-point scale will be used with a lower score indicating a better outcome: 0 = None 1. = Mild 2. = Moderate 3. = Severe
次要结局
