A self-contained, hand-held device for providing radiation-based dermatological treatments includes a device body configured to be handheld by a user; a laser supported in the device body, the laser including a laser beam source configured to emit a laser beam; an application end configured to be manually moved across the skin during a treatment session; and electronics configured to control the laser beam source to deliver the laser beam to the skin at a delivered radiation intensity at the skin sufficient to provide an effective dermatological treatment. The device may exclude any optics downstream of the laser beam source, and may provide Class 1M or better eye safety classification per the IEC 60825-1 Class 1M AEL (Accessible Emission Limit) specification
