Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
To our knowledge, there are no reports in the literature comparing the effects of different wavelengths of the PDL for the treatment of scars. The objective of this study was to compare the effects of the PDL at 585nm vs 595nm in the treatment of postsurgical linear scars starting the day of suture removal.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Treatment: PDL 450 microseconds
The scar will be randomly divided into three equal fields. One third of the scar will receive PDL using a 7 mm spot size at 4.0 J (Joules) for 450 microseconds. First treatment will be immediately after suture removal, and then monthly for 3 months.
PDL 450 microseconds
The scar will be randomly divided into three equal fields. One third of the scar will receive PDL 585 nm using a 7 mm spot size at 4.0 J (Joules) for 450 microseconds. First treatment will be immediately after suture removal, and then monthly for 3 months.
Treatment: PDL 1.5 milliseconds
The scar will be randomly divided into three equal fields. One third of the scar will receive PDL using a 7 mm spot size at 4.0 J (Joules) for 1.5 milliseconds. First treatment will be immediately after suture removal, and then monthly for 3 months.
PDL 1.5 milliseconds
The scar will be randomly divided into three equal fields. One third of the scar will receive PDL 585 nm using a 7 mm spot size at 4.0 J (Joules) for 1.5 milliseconds. First treatment will be immediately after suture removal, and then monthly for 3 months.
Control
The scar will be randomly divided into three equal fields. One third of the scar will not receive treatment
