The Effect of Violet Device Dosed Ultra Violet-C Light (UV-C) Exposure on Healthy Hand Skin

NCT05313555 · Status: ACTIVE_NOT_RECRUITING · Phase: NA · Type: INTERVENTIONAL · Enrollment: 30

Last updated 2025-07-08

No results posted yet for this study

Summary

The purpose of this trial is to determine the safety of ultraviolet light (UV-C) irradiation as a method to sanitize hands instead of chemical-based sanitizers.

Eligible participants will be enrolled and receive treatment with the Violet UV-C device or UV-B. Punch biopsies will be performed following UV exposure to quantify any changes in cellular and molecular properties of the tissue.

  • Healthy Volunteers

Interventions

DEVICE

Ultraviolet Light (UV-B)

This control group will receive a UV-B exposure as a positive control. Participants will have punch biopsies after exposure.

DEVICE

Ultraviolet lights (UV-C)

Violet is tabletop device that emits filtered UV-C (200nm-230nm; peak at 222nm). Participants will choose, based on availability, to be in groups that deliver 1 cycle, 10 cycles, 15 cycles or 25 cycles of the Violet. The subject will be exposed for no more than 5 minutes and 20 seconds in total. Participants will have punch biopsies after exposure.
