Acne Treatment With 3-Step Broadband Light Protocol.

BACKGROUND AND

OBJECTIVE

A new 3-step protocol using broadband light allows patients with moderate to severe in ammatory acne to avoid potential side effects of systemic acne treatments and the risks and uncertainties associated with laser and light treatments to date. The protocol also addresses acne scarring and, with appropriate modi cations, all skin types.

METHODS

The protocol consists of 6 to 8 treatments performed with a single device that allows the user to select wavelength, spot size, uence, and pulse duration. Step 1 uses blue light with a large spot size and low uence to kill Propionibacterium acnes. Step 2 features red and yellow light with a smaller spot size and higher uence, which together exert anti-in ammatory effects and trigger neocollagenesis. Step 3 employs visible and infrared (IR) light with a high uence and 12-second pulse length, delivered with a constant motion technique, to enhance previous results while also targeting areas of frequent breakouts.

RESULTS

Challenging cases treated with the protocol include a young adult female with a nearly decade-long history of in ammatory and cystic acne. Her skin remained clear more than 6 months post-treatment. She reported her scarring reduction at 90%. Having treated more than 100 patients with the protocol, the author reports that approximately 80% of patients clear completely or achieve at least a 75% improvement in their in ammatory acne. Acne improvements start appearing 2 to 3 days after a treatment session. Red, purple, raised, or depressed acne scars less than 1 to 2 years old begin to fade 1 to 3 weeks post-treatment.

CONCLUSION

The 3-step protocol is safe and effective for patients with moderate to severe in ammatory acne and acne scarring. <em>J Drugs Dermatol. 2016;15(11):1382-1388.</em>.
