Store ice cubes in your freezer for a minimum of 3 hours before use. Pick one ice cube from the freezer, remove the seal, and pop it out of the mold. Apply morning and/or evening to clean skin of the face, neck, and décolleté, using gentle, circular motions. Avoid holding the ice cube in one place for more than 2 seconds to prevent potential skin irritation. You can apply it directly to the skin or wrap the cube in a thin cotton fabric. Follow with a serum and moisturizer. Before the first application, it is recommended to perform a sensitivity test.
