Abstract

Disclosed are a method and a dermatological device for treatment of acne that includes an intense violet-blue diode light source (20) and an output window (10) that contacts the skin during the light emission to provide a heat sink for the skin. Another disclosed device configuration and method includes a handheld and cordless device with an intense violet-blue light source and a contact-based heat sink for the skin. A further configuration and method provides a small area illumination and a contact-based heat sink. A still further configuration and method provides a handheld and cordless device having a small area illumination and contact-based heat sink.
