The Hiding in Frost Technique produces a visually clouding frost by causing the temperature of air to fall below the freezing point, effectively freezing any ambient water vapour in the vicinity. The frost allows the user to become transparent within it. Upon being struck with an attack, the user becomes visible. Due to the frost being created with the user's chakra, it is likely that any Sharingan and Rinnegan-user will see the frost coloured by their opponent's chakra, which will effectively hide the user from the dōjutsu. Those not using dōjutsu can see in the mist, but since the user is transparent, it voids that sense. An effective way of finding the user is by the use of excellent hearing.
Despite frost being the frozen deposition of water vapour, it is not completely clear whether or not this technique involves Ice Release or is just another form of Water Release, due to the anime's tendency of incorporating ice producing Water Release techniques.
