结局指标
主要结局
Photodamage Score Change
时间窗: Baseline and 3 months post last treatment
The photodamage is assessed by examining fine wrinkles, mottled hyperpigmentation, and overall integrated assessment of photodamage. These 3 categories are broken down into their own scales of 0 to 4 based on severity. 0 indicates none, 1 indicates minimal, 2 indicates mild, 3 indicates moderate, and 4 indicates severe. The total points from all 3 categories added up will range from 0 to 12, where 12 is the most photodamage possible. A decrease in score indicates less photodamage.
Changes in Facial Scarring Score
时间窗: Baseline and 3 months post last treatment
Physicians will examine the subjects' facial scarring using the Physician Global Scarring Grading (PGSG) scale. This scale counts and types scars by tallying up of the number and severity of the scars according to an organized grading system, where 0 is the lowest point value and represents no scarring. The theoretical highest score possible is an 84. The change in the score from the baseline to the follow up was collected. A negative change indicates a decrease in points (which indicates improvement).
Number of Participants With Signs of New Collagen Generations
时间窗: 3 months post last treatment
Subjects will have one 3mm punch biopsy obtained pretreatment from an inconspicuous area and subsequent biopsies at one or any of the following visits after treatment. Pathologies will be provided by pathologists who are able to determine any developments of dermal mucus, dermal elastic fibers, or changes in collagen III. An increase in any of these categories corresponds with skin rejuvenation.
