Disclosed is a skin treatment device for personal use. The device includes an optical radiation providing module operating in pulsed or continuous operation mode, a mechanism for continuously displacing the device across the skin, and a device displacement speed monitoring arrangement. When the device is applied to skin, the optical pulses repetition rate establishes the power of the optical radiation as a function of the device displacement speed. The device a hair removal mechanism configured to mechanically remove hair from the treated segment of the skin.
