Summary

This trial is testing how well gentian violet works to treat HS by surveying patients and measuring changes in skin appearance.

Who is the study for?
This trial is for adults with active Hidradenitis Suppurativa (HS), a skin condition. Participants must be willing to have one treatment of Gentian Violet and agree to a follow-up after one month. It's not suitable for children, those without current HS lesions, or individuals unable to evaluate their quality of life for the survey.
What is being tested?
The study tests how effective Gentian Violet is in treating HS by examining changes in the skin and collecting patient feedback through surveys about their experience and results after treatment.
What are the potential side effects?
While specific side effects are not listed, Gentian Violet may cause skin irritation, staining of the skin and nearby objects, possible allergic reactions, or other localized effects at the site of application.
