Brief Summary:
Randomized, double-blind, placebo-controlled, research pilot study. 30 subjects aged 22-55 years old of all skin types will be asked to sign an informed consent form prior to any study procedures. Subjects must have at least 1 but up to 3 acne scars ≥3 mm or ≤ 10 mm located on the cheeks or forehead. Subjects will receive one treatment (Restylane® Silk or Placebo) in each scar at day 0, and Month 1 (2 total treatments per scar during the study). Subjects will be asked to come to 10 visits: Screening visit (up to 35 days prior to Baseline), Baseline (Day 0), Day 7, Day 14, Month 1, Month 2, Month 3, Month 4, Month 5, and Month 6 (study exit visit). The treatment area will be evaluated at each visit by the unblinded investigator regarding erythema, bruising, inflammation, itching, stinging/burning, brightness, fullness, smoothness, and clarity. Safety and adverse events will be captured at each visit only by the unblinded investigator.

Detailed Description:
Randomized, double-blind, placebo-controlled, research pilot study. 30 subjects aged 22-55 years old of all skin types will be asked to sign an informed consent form prior to any study procedures. Subjects must have at least 1 but up to 3 acne scars ≥3 mm or ≤ 10 mm located on the cheeks or forehead. Subjects will receive one treatment (Restylane® Silk or Placebo) in each scar at day 0, and Month 1 (2 total treatments per scar during the study). Subjects will be asked to come to 10 visits: Screening visit (up to 35 days prior to Baseline), Baseline (Day 0), Day 7, Day 14, Month 1, Month 2, Month 3, Month 4, Month 5, and Month 6 (study exit visit). The blinded investigators will evaluate the target scar using the Acne Scar Rating Scale (ASRS), rate the target acne scar regarding treatment effect on a -5 ("Markedly worse"), to 0 ("Neutral Improvement"), to 5 (Markedly Improved (Clear or nearly clear)) point scale, and evaluate the skin quality (regarding brightness, fullness, smoothness, and clarity). Subjects will give the acne scar a score on the subject VAS acne scar satisfaction scale marking between 0 ("Not satisfied with Acne Scar at Day 0") and 10 ("Extremely Satisfied with Acne Scar at Day 0"). The treatment area will be evaluated at each visit by the unblinded investigator regarding erythema, bruising, inflammation, itching, stinging/burning, brightness, fullness, smoothness, and clarity. The subject will have their vital signs taken, complete a symptom diary (only if the subject experiences side effects or adverse events), complete a DLQI, and have photos (VECTRA and 2D digital photographs) taken of the treatment area. Efficacy measures will only be completed by the blinded investigator. Safety and adverse events will be captured at each visit only by the unblinded investigator.

Arm Intervention/treatment
Experimental: Restylane Silk, 1.0 ml
Subjects must have at least 1 but up to 3 acne scars ≥3 mm and ≤ 10 mm located on the cheeks or forehead. Subjects will receive one treatment (Restylane® Silk) in each scar (up to 3 acne scars) at day 0, and Month 1 (2 total treatments per scar during the study). Subjects will remain blinded to the treatment administered to them during these visits.
Device: Restylane Silk, 1.0 ml
Restylane® Silk was approved in 2014 submucosal implantation for lip augmentation and dermal implantation for correction of perioral rhytids in patients over the age of 21.

Placebo Comparator: Placebo (Saline), 1.0 ml
Subjects must have at least 1 but up to 3 acne scars ≥3 mm and ≤ 10 mm located on the cheeks or forehead. Subjects will receive one treatment (Placebo (Saline)) in each scar (up to 3 acne scars) at day 0, and Month 1 (2 total treatments per scar during the study). Subjects will remain blinded to the treatment administered to them during these visits.
Device: Saline, 1.0 ml
Simple saline solution. To be used as placebo (control). No active ingredients.




Primary Outcome Measures :
  1. 1 grade improvement of ASRS from baseline [ Time Frame: Baseline-6 Months post first injection. ]
    The primary endpoint is a one grade improvement of the acne scar from baseline as rated on the ASRS.


Secondary Outcome Measures :
  1. Statistically significant improvement of the acne scar from baseline [ Time Frame: Baseline-6 Months post first injection. ]
    A significant improvement of the acne scar from baseline as rated by the

  2. Statistically significant improvement of the skin quality from baseline [ Time Frame: Baseline-6 Months post first injection. ]
    A significant improvement of the skin quality of the treatment area as rated by the investigator using the skin quality assessment scale.


Other Outcome Measures:
  1. Statistically significant acne scar area reduction from baseline. [ Time Frame: Baseline-6 Months post first injection. ]
    The first exploratory endpoint is a significant reduction of acne scar area as measured by the VECTRA system 6 months post first treatment
