Clinical Trial Summary

Clinical Trial comparing the 1,550-nanometer fractionated photothermolysis system laser to the 755 nanometer picosecond laser using a split-face (Right-Left) comparison. Patients will receive laser treatments at week 0, week 4, and week 8. Photographs will be taken prior to laser treatment at each visit, and at the week 24 follow-up visit. Photographs will be reviewed by blinded assessors to rate each side of the face and change from baseline photos.


Description:

This is a Clinical Trial comparing the 1,550-nanometer fractionated photothermolysis system laser to the 755 nanometer picosecond laser using a split-face (Right-Left) comparison. Both of these lasers are currently FDA approved for acne scarring. Approximately 18 subjects, men and women with Fitzpatrick skin types I through V and facial acne scarring of grades III-IV (moderate to severe) will be enrolled. Both sides of the participants' face should have similar amount and severity of acne scarring. Participants will be over 18 years old. Patients have to be otherwise healthy without a history of skin cancer, keloidal scarring, localized or active infection, immunodeficiency disorders, and light sensitivity. Patients have to be overall healthy without a history of skin cancer, keloidal scarring, localized or active infection, immunodeficiency disorders, and light sensitivity. Per PI discretion, any serious medical condition that may interfere with the study. In addition, patients who have been taking isotretinoin for a period of 6 months before treatment will be excluded. Patients will have photographs taken at every visit prior to the laser treatments at week 0, week 4, and week 8. Photographs will also be taken at the week 24 follow-up visit. Photos will then be assessed by qualified blinded reviewers for comparison.
