What is Broadband Light (BBL) and how is it different from a Laser? In this episode of KestyMD Esthetics, Dr. Kat Kesty, Double Board-Certified Dermatologist and Fellowship-Trained Laser Surgeon breaks down everything you need to know about BBL and IPL (Intense Pulsed Light).

Dr. Kesty explains how BBL and IPL work, the difference between these light-based treatments and traditional lasers, what skin concerns they can treat, and why choosing an experienced provider matters. She also discusses the narrow therapeutic window of BBL and IPL, treatment settings, potential risks, and why expertise with both the device and your skin type is critical for achieving safe, effective results.
