Liquid Nitrogen(LN) is used as a treatment for removing freckles, pigment spots and warts from any area of the body. All that is involved is the application of liquid nitrogen (a very cold liquid similar to dry ice) on the area to be treated for a few seconds. This may have to be repeated once or twice over the following weeks if pigmentation is deep.
What results can I expect?
After a treatment of LN, the affected skin will turn darker then peel off, effectively removing the freckle or pigment spot and revealing new skin. The whole process takes about one week. At first the new skin may be red but will return to a normal skin color one week after treatment.
How often do I need the treatment?
For most freckles and pigment spots, one treatment is all that is required. For removing warts, you may require two or three treatments.
How long will it last?
Generally the treatment is permanent. In the case of warts, there is always a chance of recurrence.
What is the treatment like?
The treatment feels very cold, exactly the same as holding a block of ice to the skin. There is a cold stinging sensation that only lasts a few seconds at most.
Are there any side effects?
If the treatment is given by a doctor experienced in this procedure the risk of side effects is very small. There is a possibility of actually making the pigmentation worse by applying too much LN to the skin.
What is the recovery time?
Generally, the treated area will become darker and form a scab which falls off after about a week. The new skin may look slightly red but will return to the normal color of the surrounding skin after another week.
