A device for providing radiation-based dermatological treatments includes a device body configured to be handheld by a user; a VCSEL laser supported in the device body, the VCSEL laser including multiple spaced-apart VCSEL beam sources configured to generate multiple discrete laser beams for generating multiple discrete treatment spots on the skin; an application end configured to be manually moved across the surface of the skin during a treatment session; and electronics configured to control the multiple VCSEL beam sources to emit the multiple discrete laser beams toward the skin to provide a dermatological treatment.
