Possible side effects

Although cryotherapy is a relatively low-risk proce-
dure, some side effects may occur as a result
of the treatment. They include:
Permanent changes in pigmentation.
Both hypopigmentation (lightening of the skin)
and hyperpigmentation (darkening of the skin)
may occur after cryotherapy. Both generally last
a few months, but can be longer lasting.
Sensory impairment. Though rare, damage
to nerves is possible, particularly in areas where
these are positioned closer to the surface
of the skin, such as in the fingers, the wrist,
and the area behind the ear. Reports suggest
effects will disappear within several months.
Spattering of the cryogen during spraying,
when the end nozzle freezes. The innovation
of Freezpen is the direct application of nitrous oxide
under high pressure (55 bar).
This high pressure jet may cause minor shards
of frozen humidity in the air to be blown away
in a radius of approximately 30 cm. They will thaw
the moment they might touch healthy skin.
Hair loss. Hair follicles are easily damaged by
cryosurgery and permanent hair loss is not uncommon.
