Outcome Measures

Primary Outcomes (3)

  • Overall Improvement of Acne Scarring

    Subject assessment of the percent improvement of acne scarring compared to baseline and based on the quartile scale (0: no improvement; 1: 1-25% improvement; 2: 26-50%; 3: 51-75%; 4: 76-100% improvement).

    Baseline, 1 month and 3 months post-treatment

  • Average Improvement in Surface Texture

    Subject assessment of the percent improvement of surface texture compared to baseline and based on the quartile scale (0: no improvement; 1: 1-25% improvement; 2: 26-50%; 3: 51-75%; 4: 76-100% improvement).

    Baseline, 1 month and 3 months post-treatment

  • Degree of Atrophy

    Subject assessment of the percent improvement in extent of atrophy compared to baseline and based on the quartile scale (0: no improvement; 1: 1-25% improvement; 2: 26-50%; 3: 51-75%; 4: 76-100% improvement).

    Baseline, 1 month and 3 months post-treatment

Secondary Outcomes (1)

  • Pain Tolerance

    At treatment visit (up to 3 visits)

Study Arms (1)

Fractional carbon dioxide laser system

EXPERIMENTAL

Thirty total healthy subjects from two research centers with skin type I-IV of moderate to severe acne scarring received treatment with the 10,600 nm fractional carbon dioxide laser system.

Device: 10,600 nm fractional carbon dioxide laser system

Interventions

1-3 laser treatments using 20-100 millijoules (mJ) with 100-400 microscopic treatment zones (MTZ)/cm2 per pass and total density of 600-1200 MTZ/cm2

Also known as: Fraxel Re:pair laser
Fractional carbon dioxide laser system

Eligibility Criteria

Age18 Years - 75 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Have Fitzpatrick skin type I-V. (Type I is blonde/red hair with freckles and Type V are Hispanics and lighter African Americans.)
  • Are male or female.
  • Are between 18 and 75 years of age.
  • Have moderate to severe acne scarring. Acne scarring will be assessed with the Acne Scar Severity Scale. Subjects will be eligible for treatment if the area to be treated is scored as having an Acne Scar Severity Score \> 4 according to the Acne Scar Severity Scale (0-9).
  • Are able to read, understand, and sign the Informed Consent.
  • Are willing and able to comply with all follow-up requirements for a minimum of 8 months.

You may not qualify if:

  • Have had active localized or systemic infections within 6 months of enrollment
  • Have compromised ability for wound healing, such as: malnutrition, oral steroid use, history of collagen vascular disease (e.g. lupus, scleroderma, history of keloid formation (raised and thickened scars), atrophic dermatitis (extreme skin irritation or itchiness) or immunologic abnormalities such as vitiligo (white patches of skin due to loss of pigment)
  • Have immunocompromised status (inability to resist infection, etc.)
  • Have been treated with lasers, chemical procedures, or other cosmetic procedures on the area to be treated within 6 months of enrollment
  • Have taken Accutane within 12 months of enrollment
  • Are allergic to lidocaine (skin numbing agent)
  • Are allergic to Valtrex (an anti-viral medication)
