A method and a system for skin treatment are presented. A muscle stimulating element is configured to provide muscle stimulation to a muscle layer located below the skin tissue, a handheld applicator is configured to be placed in vicinity of the skin tissue to deliver a muscle stimulation flow from said muscle stimulating element to cause selective contraction and expansion of one or more muscles in the muscle layer located below the skin tissue; and a control board is configured and operable to activate the muscle stimulating element according to one or more activation patterns adapted to provide said muscle stimulation flow to thereby provide one or more treatments to the skin tissue.
