Temperature is the crucial key when it comes to the melt factor of lip balm. Lip balm melts on your lips more readily than it would in your pocket because of your body temperature. Depending on the blend of oils and their individual properties (density), each element has what we classify as a melting point. Lip Balm is usually hard at room temperature, 60 - 65Âº, our normal body temperature is 98.6Âº. Our body temperature is definitely higher than what we consider normal room temperature, so the moment you apply lip balm it melts on your lips.
