Your treatment

You have just received treatment with liquid nitrogen.  This is a very cold substance and when it is applied to the skin it can cause a blister to form, similar to a burn.

You may experience some pain. This should be easily controlled with simple pain–relieving drugs such as ibuprofen or paracetamol (ensure that you follow the instructions on the packet).


  • There is no need to cover the treated areas as long as the blisters remain intact.
  • If they become tight or start to expand they should be pricked.
  • Do this using a needle sterilised in a flame, and apply a simple dressing.

Sometimes liquid nitrogen treatment will need to be repeated. Your doctor will have arranged a follow-up appointment for you if this is likely to be the case.

Post-treatment appearance

The skin is usually smooth, flat and pink once the blister has healed.  It then fades back to a pale colour.  The treated site may not suntan as well as the rest of your skin.
