OPTICAL APPARATUS FOR SKIN TREATMENT, METHOD FOR CONTROLLING THE OPTICAL APPARATUS, AND METHOD FOR SKIN TREATMENT

摘要

The present invention relates to an optical apparatus for skin treatment and to a method for controlling the optical apparatus. The optical apparatus includes a light-illumination part for illuminating light generated in a light-generation part onto a target position of the skin, a cooling part for injecting cooling gas onto the target position to cool the surface of the skin, and a control part for controlling the operation of the light-illumination part and cooling part. The control part controls the light-illumination part and the cooling part such that the light-illumination part illuminates second light onto the target position after the light-illumination part illuminates first light onto the target position, and the cooling part injects the cooling gas onto the target position.
