Yes it will help you, but remember that elemental protection bonuses are not sumables. So I recommend you to use another Resilence potion if you have a full death protection set. For example, Ice Resilence so you will resist UE Combos too :)
Remember that if you Log Out of the game your Resilence Potion time will not run and you can always check the duration in your cyclopedia. Cyclopedia > Character > General Stats > Combat Stats.
