Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Methods: This prospective, randomized, 3-arm, open-label, vehicle-controlled study will enroll patients scheduled to undergo treatment for stasis dermatitis with hyperpigmented skin lesions. Patients will be allocated to either Nd: YAG 1064 nm short pulse laser-nanoseconds (group 1), or Nd: YAG 1064 nm ultra-short-pulse laser-picoseconds (group 2), or cold cream vehicle control (group 3). All treatments are scheduled for 6 visits with pre-defined dates, with a final follow-up visit at intervals of 28 to 35 days. Primary outcomes include colorimetry analysis, secondary outcomes pre- and post-photographic analysis, and DLQI quality-of-life assessment.
Conclusions: The results of this trial will provide high-quality evidence to guide clinical practice on optimal management of hyperpigmented skin lesions secondary to stasis dermatitis.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Arm 1: ND YAG laser: 1064 nm short pulse (nanoseconds) - Omer Smart
Laser treatment
short-pulse ND: YAG 1064 laser
Nd: YAG 1064 nm short pulse laser (5 nanoseconds), 4 mm spot size, from 100 to 1000 mJ total energy, treatment scheduled for six visits with pre-defined dates, with intervals of 28 to 35 days. The device will be Omer Smart, a Q-Switch Laser produced by Medical San (Lajeado, RS, Brazil).
Arm 2: ND YAG laser: 1064 nm ultra- short pulse (picoseconds) - omer Premium
Laser treatment
ultra-short-pulse ND: YAG 1064 laser
Nd: YAG1064 nm ultra-short pulse laser (400 picoseconds), 2 to 10 mm spot size, from 100 to 1000 mJ total energy, treatment scheduled for 6 visits with pre-defined dates, with intervals of 28 to 35 days. The device will be Omer Premium, a picolaser produced by Medical San (Lajeado, RS, Brazil).
Arm 3
Control vehicle (cold cream)
cold cream
The control vehicle is a cold cream, supplied by HERVA'S manipulation pharmacy. The composition of cold cream will be beeswax, acetyl palmitate, BHA, cetearyl alcohol, propylparaben, and water. This topical agent will be applied to patients daily throughout the treatment period. It is scheduled for six visits with pre-defined dates, with intervals of 28 to 35 days.
