92% SAW LONG-TERM HAIR REDUCTION

The Flasher 2.0 Is Clinically Proven

The Clinical Trial Design

BY DAN FRIEDMANN, MD
BOARD-CERTIFIED DERMATOLOGIST

This third-party, before-after clinical trial was designed to test the efficacy and safety of The Flasher™ 2.0, Nood's at-home, handheld intense pulsed light (IPL) device. Participants were followed in-clinic at Austin’s Westlake Dermatology over sixteen weeks.

Each participant performed 10-minute treatments at home on a single armpit twice weekly for twelve weeks. They visited Westlake Dermatology after four, eight, and twelve weeks of treatment to measure hair reduction and patient satisfaction and one final visit four weeks after their last treatment.

Low Discomfort Levels

Users were asked about their average discomfort levels while using The Flasher™ 2.0 set to the highest level, seven, halfway through the 12-week treatment period. They rated their pain by marking a validated horizontal analog scale (with 0 being ‘no pain’ and 10 being ‘intolerable pain’).

The average discomfort level was < 1.
