Dermapen Cryois an advanced cryotherapy innovation that offers
advantages over traditional spray can-type cryotherapy.
Firstly, it delivers
a nitrous oxide (N2O) jet that is much colder and
at a higher pressure than
traditional cryo sprays, making for an
extremely fast and effective treatment.
It is able to treat a 2mm lesion in just 10 seconds,
and is able to go up to
This means it will save you money on repeat visits.
Dermapen Cryo will only treat your lesion, and not the
surrounding tissue, because of its special applicator tips that
can be selected
for different sized lesions.
This means that your treatment will involve
minimal discomfort and few side effects.
It also means that lesions on the face and the
area around the eyes can be safely treated too.
Cryotherapy (‘cold surgery’) is a highly effective and safe
that is used to freeze and destroy benign skin lesions.
liquefied nitrous oxide to destroy tissue by freezing
the inter-cellular fluid
which forms ice shards and crystals that rupture
the cell membrane, destroying
The clinician will hold the applicator as close as possible to
the lesion, and move it quickly towards and away from it. Depending on the
lesion size and depth, the treatment could be 1 to 30 seconds.
After the first freezing cycle, the tissue will be allowed to
thaw for about 30 seconds.
The second freeze cycle will start. The tissue will freeze
faster than during the first freezing cycle.
The penetration rate of freezing with the Dermapen Cryo is
approximately 1mm per 5 seconds.
How safe is cryotherapy?
A. Cryotherapy is a relatively low-risk procedure. Dermapen Cryo™
delivers N2O directly to the lesion, and not the healthy surrounding
tissue. Dermapen Cryo™ is both CE and FDA registered.
How long are Dermapen Cryo™
A. The penetration rate of freezing with the Dermapen Cryo™ is
approximately 1mm per 5 seconds, with a maximum freezing depth of 3 to 6 mm
depending on the used applicator. The duration of the treatment time will
depend on the surface area and the thickness of the tissue being treated. Upon
the clinical evaluation of the thickness of the lesion, the operator will
choose an application time from 1 to 30 seconds.
Is the treatment painful?
A. There will be a pain sensation similar to a ballpoint pen being
pushed onto the skin when the nitrous oxide reaches the bottom of the lesion.
There might be a little residual stinging for a few minutes after treatment.
Occasionally a blister might form and persist for a few hours.
Will there be a follow up
A follow up
visit is recommended after 2 to 4 weeks to confirm that all pathological tissue
has disappeared or if a follow
up treatment is necessary.
What if I have darker skin?
A. Repeated short freezing cycles of 3 to 6 seconds at two-week
intervals are recommended if you have a darker skin type.
Are there any side effects?
Therapy is relatively low risk. There are a few side effects that may occur as
a result of treatment, including:
(hypopigmentation and hyperpigmentation)
• Nerve damage (particularly in areas where nerves lie close to
the surface of the skin, on fingers, wrist, area behind the ear)
Shards of frozen
ice (minor shards of frozen ice may blow out, that will thaw on contact with
damage and permanent alopecia (especially when treating lesions on sites with
coarse terminal hair)
Discuss any concerns with your
How much will the treatment cost?
The cost of
treatment will depend on the clinic and the size of the lesion. Make an
appointment to discuss costs and to assess your lesion.
