Study Summary

This trial aims to understand why laser treatment reduces pain & itch associated with hypertrophic burn scars.

Who is the study for?
This trial is for individuals with hypertrophic burn scars that are painful, itchy, or hypersensitive. Participants must have had the burn within the last two years and be planning to undergo laser treatment. They should agree to biopsies and a year of follow-up. Pregnant individuals or those on certain medications like steroids, antihistamines, pain relief drugs, or those affecting wound healing cannot join.Check my eligibility
What is being tested?
The study tests how effective Fractional CO2 laser therapy (Luminis ultrapulse) is in reducing pain and itchiness in hypertrophic burn scars. It involves histological evaluations over different stages of treatment to understand the underlying mechanisms behind symptom improvement.See study design
What are the potential side effects?
Potential side effects may include discomfort at the site of laser application, skin redness, swelling, changes in skin pigmentation, scarring from biopsies taken during the study process and possible allergic reactions to topical or local anesthetics used.
