The hot and cold hammer is used as a facial treatment and massage tool, with both sides of the hammer head reaching different temperatures (one hot, one cold) simultaneously. The hot side of the hammer relaxes and opens pores while stimulating blood circulation beneath the skin. The cold side soothes tired and overheated skin, and closes pores while locking moisture into the skin. The hot hammer opens facial pores so they can be cleansed of debris, toxins, excess oil and bacteria. The cold hammer helps tighten the skin, which promotes elasticity while smoothing wrinkles and crows’ feet.
