Had a spot frozen off with liquid nitrogen today? Here's what's normal over the next few weeks, and when to call your GP.
Redness, stinging and swelling at the site. This usually settles within the day.
A blister forms. The fluid may be clear or blood-tinged — both are normal and expected. Do not pop it on purpose.
Puffy eyelids are common, often worst the morning after, and usually settle within a few days.
The blister dries into a scab. Dab on a thin layer of plain petroleum jelly and leave it alone — don't pick or scratch it off.
The skin may look paler or darker than the surrounding area for a while. This is common, especially in darker or olive skin, and usually fades over time.
| Location | Typical healing time |
|---|---|
| Face | About 5–10 days |
| Hand | About 3 weeks |
| Lower leg | Up to 3 months (slower circulation lower down the leg) |
Healing speed varies by site, how deep the freeze was, and your own circulation and general health — these are typical ranges, not guarantees.
