Not sure if serious but two problems: potentially too cold right out of the freezer (damage to your skin!) AND not cold enough after it has come in contact with your skin for a while.

Melting ice is similar to boiling water . . . it comes up to a certain temperature (212F for boiling, 32F for melting) and then stays there until it changes states (steam as it boils and liquid as it melts). But by adding different concentrations of salt to your water before putting it in the freezer (salt will lower the freezing point), you could essentially dial in the melt temperature. More salt = lower freezing point, but you'd have to wait until it starts to "melt" and then verify its temperature to confirm that it wasn't too cold.

But, uh, do you really want to try this

Colligative properties!
