This randomized, single-center, double-blinded, controlled, clinical trial was conducted to investigate the tolerability, safety, and efficacy of a post-procedure cream when used immediately after radiofrequency microneedling and for seven days post-procedure with twice daily application in healthy female subjects ages 35-65 with moderate facial photodamage (Grade II or III) using the Glogau Scale of Photoaging. Furthermore, this clinical trial will compare the active post-procedure cream to a comparator anhydrous cream product often paired with skin rejuvenation procedures. A total of 11 healthy female subjects completed the study. Six (6) subjects in the active arm and five (5) subjects in the comparator arm.

A 7-day washout period is required for all subjects prior to radiofrequency microneedling procedure. Tolerability (investigator and subject) and safety will be assessed through grading at baseline, post-procedure, post-procedure/post-product application, twenty-four (24) hours post-procedure, three days post-procedure, and seven days post-procedure. Tolerability parameters included erythema, edema, dryness, burning, stinging, and itch. Efficacy evaluation using the Glogau photoaging scale was performed at screening, baseline, and day 7 post-procedure. The Global Aesthetic Improvement Scale (GAIS) was performed at day 7-post procedure. Self-assessment questionnaire and clinical photography will be completed at all timepoints. A total of 11 subjects completed study participation. Six (6) subjects in the active arm and five (5) subjects in the comparator arm.

A fractional bipolar radiofrequency microneedling device will be performed at Visit 2, after the 7-day washout period. Subjects were numbed 45 minutes prior to RF microneedling with topical numbing Benzocaine 20%/Lidocaine 6%/tetracaine 4%. Bony areas, periorbital, forehead, and chin were treated with 15 watts at a 2 mm needle depth on cycle mode. All subjects received 20 watts at 3 mm depth on cycle mode on soft tissue, neck, and cheeks.
Facial cleanser to be used by subjects twice-daily. This product was used during the entire 14-day study (7-day washout period and 7-day post-procedure timeline).
Bland moisturizer to be used by subjects twice daily during the 7-day washout period. Use 1 to 2 pumps and place all over face and avoid the eye area.
Bland sunscreen to be used by subjects after cleansing and the facial moisturizer during the 7-day washout period. Bland sunscreen to be used by subjects after cleansing and after the active post-procedure cream and comparator anhydrous cream. Use the provided sunscreen and reapply as needed throughout the day and per recommendation of the FDA, every 2 hours.

Investigator Tolerability Scores
The primary tolerability endpoint will be Investigator Tolerability Assessment of erythema, edema, and dryness. A change in scores or lack of significant change after procedure, immediately post-procedure, post product application, Day 1 (24 hours), Day 3, and Day 7 in comparison to baseline (post-procedure) indicates tolerability / safety of the test material. Four-point scale with a lower score indicating a better outcome. 0 = None 1. = Mild 2. = Moderate 3. = Severe
Time frame: 14 days
Incidence of Adverse Events
The primary safety endpoint will be determined by the incidence and severity of adverse events in healthy subjects, including immediate post-procedure and through-out the length of the study.
Time frame: 14-days
Subject Tolerability Scores
Subject tolerability endpoint will be Subject Tolerability Assessment of burning, itching, and stinging. A change in scores or lack of significant change after procedure, immediately post-procedure, post product application, Day 1 (24 hours), Day 3, and Day 7 in comparison to baseline (post-procedure) indicates tolerability / safety of the test material. Four-point scale with a lower score indicating a better outcome. 0 = None 1. = Mild 2. = Moderate 3. = Severe
Time frame: 14 days
Clinical Efficacy Grading
To evaluate the efficacy of the neurocosmetic on self-perceived improvement and objective grading. Investigator clinical grading, using the Glogau photoaging scale performed at Visit 1 (screening), Visit 2 (baseline, 7-days post-washout), and Visit 5 (14 days). The Global Aesthetic Improvement Scale (GAIS) to be completed at Visit 5 (14 days). GAIS Scoring: Very much improved- Optimal cosmetic result for the treatment in this patient. Much improved- Marked improvement in appearance but not completely optimal for this patient. A touch-up would slightly improve the result. Improved - Obvious improvement in appearance from the initial condition, but a touch-up or re-treatment is indicated. No change- The appearance is the same as than the original condition. Worse- The appearance is worse than the original condition.
Time frame: 14 days
Self-Assessment Questionnaire
The secondary efficacy endpoint will be the Self-Assessment Questionnaire. A change in response values at post-procedure/post-product application (Visit 2), Day 1 (Visit 3), Day 3 (Visit 4), and Day 7 (Visit 5) indicates, and improvement compared to baseline response values. Baseline responses will be set to post-procedure/post-product application. Subjects are asked to rate based on a scoring system of the following: from 5 (completely agree) to 1 (completely disagree). The best outcome is to Completely Agree with the statement / question being asked.
Time frame: 14 days
