Primary | Percent Change in Volume of Striae Via Antera 3D Imaging System Analysis From Baseline to 16 Weeks Post-final Treatment | Change from baseline to the follow-up visit 16 weeks post-final treatment as a percentage of baseline volume. | 16 Weeks Post-Final Treatment (Week 28) | |
Primary | Overall Stretch Mark Improvement From Baseline to 16 Weeks Post-Final Treatment Assessed by the Global Aesthetic Improvement Scale (GAIS) | Evaluate the efficacy of overall stretch mark improvement assessed live by the Investigator and a subject assessment of stretch mark including the Global Aesthetic Improvement Scale (GAIS).The Global Aesthetic Improvement Scale is a seven-grade subjective test. The PI evaluated before and after photographs and graded them for change.
Possible responses were (3) Very Much Improved, (2) Much Improved, (1) Improved, (0) No Change, (-1) Worse, (-2) Much Worse, and (-3) Very Much Worse. For reporting of outcomes, the higher the GAIS value, the greater the improvement (Range -3 to 3). |
16 Weeks Post-Final Treatment (Week 28) | |
Secondary | Subject Satisfaction | Subjects' assessment of satisfaction with the treatment using a 5 point Subject Satisfaction Scale at 16 weeks post-treatment. The Subject Satisfaction Scale is a five-grade subjective test.
Participants were asked to rate their satisfaction level with the results. Possible responses were (4) Very Satisfied, (3) Satisfied, (2) Having No Opinion, (1) Unsatisfied, and (0) Very Unsatisfied. |
16 Weeks Post-Final Treatment (Week 28) | |
Secondary | Subject Scale - Visual Analog Scale for Pain | Subject's assessment of discomfort and pain after treatments as measured by a 10 cm visual analog scale (VAS). The Visual Analog Scale is a scale from 0 cm (no pain) and 10 cm (pain as bad as it can be). Possible responses were of 0 to 0.4 cm can be considered (no pain); 0.5 to 4.4 cm (mild pain), 4.5 to 7.4 cm (moderate pain), and 7.5 to 10 cm (severe pain). No anaesthetic was used.
An average of all 4 treatments was taken for each subject. |
Treatment 1 (Week 1), Treatment 2 (Week 4), Treatment 3 (Week 8), Treatment 4 (Week 12) | |
Secondary | Subject Scale - 5 Point Scale for Treatment Tolerability | Subject's assessment of treatment tolerability as measured by a 5-point scale. Participants were asked about their tolerability level immediately post-treatment. Possible scores were; (4) Very Tolerable, (3) Tolerable, (2) Having No Opinion, (1) Intolerable, and (0) Very Intolerable.
An average of all 4 treatments was taken for each subject. |
Treatment 1 (Week 1), Treatment 2 (Week 4), Treatment 3 (Week 8), Treatment 4 (Week 12) |
