ReFa S CARAT Beauty Roller This beauty roller is characterized by its compact size, which fits perfectly on the delicate areas of the face. It generates a weak electrical current called "microcurrent," which firms the skin, refines its texture, and gives it elasticity. It is waterproof to JIS IPX7 standards, so it can be used in the bathtub. It is suitable for point care on the face, such as the corners of the mouth and between the eyebrows. Brand new, unused. Available for immediate purchase.
