A self-contained, hand-held device for providing a dermatological treatment includes a device body configured to be handheld by a user; a radiation source supported in the device body, the radiation source including a beam source configured to generate an energy beam; an application end configured to be manually moved across the surface of the skin during a treatment session; electronics configured to pulse the radiation source during the treatment session such that the beam source emits pulsed energy beams to the skin; and a displacement control system including a displacement sensor configured to determine a displacement of the device relative to the skin, and electronics configured to control at least one operational parameter of the device based on the determined displacement of the device relative to the skin.
