Skin Tags & Sun Spots

Skin Tags and Sun Spots

Skin tags and sun spots are a common problem. Here at Kings Skin Clinic we use the Dermapen Cryo™ device, which is state of art innovation that uses disposable cartridges of liquefied nitrous oxide (N2O) to deliver quick, effective cryotherapy treatments to treat these benign skin concerns.

Cryotherapy has in fact been used in medicine for many years. The nitrous oxide destroys tissues by freezing the intercellular fluid and forming ice shards and crystals that rupture the cells membrane, destroying the cells.

Because it delivers N2O directly onto the lesion and not the healthy surrounding tissue, it can safely treat lesions on the face and around the delicate eye area. Dermapen Cryo™ accurately delivers an ultra-cold, high pressure N20 jet directly onto the lesion, making it very effective. It is also very fast, with a penetration rate of 1mm per 5 seconds and able to penetrate to a depth of 5mm deep.

At Kings Skin Clinic, we can treat:

Skin tags

Skin tags do not cause any health concern, but can be unsightly. They are quite common, can form anywhere on the skin, most frequently found on the eyelids, neck and armpits.

Age spots

Age spots, also known as freckles, appear as flat brown spots that appear on areas after prolonged sun exposure, most frequently experienced by those with fair skin.

Moles, also known as nevi are raised, brown spot that contain a high concentration of pigment cells.


Cherry angiomas

Cherry angiomas, also known as ‘sensile angiomas’ or ‘Campbell de Morgan spots’ are typically found on men and women over the age of 30. These skin growth are bright red coloured, caused by broken blood vessels inside the growth, and are typically round in shape.

Warts Warts are essentially these are infections in the top layer of the skin, and are typically the result of a virus in the human papillomavirus (HPV) family. The virus penetrates the top layer of skin through a cut or a scratch and this triggers a fast growth of cells on the skin’s outer layer, thus forming the wart. Dermapen Cryo™ will not only kill the warts off and at the base but also nufflies the virus, preventing further growth in future.  warts

What are the key benefits of Dermapen Cryo™?

  • Minimally invasive
  • No injections or anesthetic required
  • Virtually Painless (even suitable for children)

Is the treatment painful?

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.

How safe is cryotherapy?

Cryotherapy is a relatively low-risk procedure. The Dermapen Cyro™ delivers N2O directly to the lesion, and not the healthy surrounding tissue. The Dermapen Cyro™ is both CE and FDA registered.

How long are Dermapen Cryo™ treatments?

The penetration rate of freezing with the Dermapen Cyro™ 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.

How many treatments do I need & when will I see improvement?

Most lesions only require one session to deliver long lasting treatment and removal. Some lesions may require two sessions to eliminate the risk of over-treatment. Results may be seen one to two weeks after treatment.

Will there be a follow up session?

A follow up visit is recommended after 2 to 4 weeks to assess the response of treatment and arrange for a further application if required.

What if I have darker skin?

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?

Dermapen Cryo™ treatments are relatively low risk. There are a few side effects that may occur as a result of treatment, including:

  • Pigmentary changes (hypo-pigmentation and hyper-pigmentation)
  • 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 healthy skin)
  • Hair follicle damage and permanent alopecia
