Recruitment status, easiest to join first

Recruiting now

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study tests whether combining two types of laser treatments—pulsed dye laser (PDL) and fractional photothermolysis—can improve how surgical scars look. Adults who had a dermatologic surgery on their trunk or limbs can join. Some participants receive the laser combination at several visits, while others receive no laser treatment. Researchers will compare scar appearance using a standard rating scale.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Pulsed Dye Laser and Fractional Photothermolysis Laser
What this could lead to
If effective, this combination laser approach could offer a simple way to reduce the appearance of postsurgical scars without additional surgery.
What could go wrong
This is a small pilot study, so results may not apply to everyone. Lasers can cause temporary redness, swelling, or discomfort, and the treatment may not improve scars for all participants.
