简要总结
This randomized, multi-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 hybrid-fractional laser treatment and for 7 days post-procedure with three times daily application in healthy female subjects aged 35-65 years with moderate to severe global face photodamage (score of 4 to 7 out of the 10-point Modified Griffiths' scale). Furthermore, this clinical trial compared the active post-procedure cream to a comparator moisturizer often paired with skin rejuvenation procedures. This is a cosmetic study with an FDA-regulated device.
A total of 16 healthy female subjects completed the study (8 subjects at both sites).
详细描述
This randomized, multi-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 hybrid-fractional laser treatment and for 7 days post-procedure with three times daily application in healthy female subjects aged 35-65 years with moderate to severe global face photodamage (score of 4 to 7 out of the 10-point modified Griffith's 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) over the course of the study. Furthermore, this clinical trial compared the active post-procedure cream to a comparator moisturizer often paired with skin rejuvenation procedures.
A 7-day washout period was required of all subjects prior to hybrid-fractional 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, and 7 post-procedure.
In addition, efficacy evaluation using the Modified Griffiths' scale was performed at screening, pre-procedure, and day 7 post-procedure. Self-assessment questionnaires were completed by subjects post-procedure/post-product application and days 1, 5, and 7 post-procedure. Clinical photography was completed at screening, pre-procedure, post-procedure/post-product application, and days 1, 3, 5, and 7 post-procedure.
A total of 16 healthy female subjects completed the study (8 subjects at both sites).

盲法说明
Subjects were randomly assigned to use the active post-procedure cream on one side of the face and the comparator moisturizer 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 efficacy or safety were blinded to the group during the study.

结局指标
主要结局
Investigator Tolerability
时间窗: 7 days
The primary tolerability endpoint will be Investigator Tolerability Assessment of erythema, edema, and dryness. A change in score of lack of significant change post-procedure/post-product application and days 1, 3, 5, and 7 post-procedure in comparison to 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
Incidence of Adverse Events
时间窗: 7 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.
Subject Tolerability
时间窗: 7 days
The subject tolerability endpoint will be Subject Tolerability Assessment of burning, itching, and stinging. A change in score of lack of significant change post-procedure/post-product application and days 1, 3, 5, and 7 post-procedure in comparison to 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
