Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Ultraviolet lights (UV-B)

Group Type ACTIVE_COMPARATOR

Ultraviolet Light (UV-B)

Intervention Type DEVICE

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

Ultraviolet lights (UV-C)

Group Type EXPERIMENTAL

Ultraviolet lights (UV-C)

Intervention Type DEVICE

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.
