Targeted Cryotherapy to Improve Keratinised Skin Lesions
Porokeratosis is a rare skin condition characterised by small, scaly patches or raised rings due to abnormal keratinisation. These lesions often have a distinctive raised border and can appear on the arms, legs or other sun-exposed areas. Although many cases are harmless, some can spread, become irritated, or — in rare cases — carry a small risk of developing into skin cancer over time.
At Cryosonic Poole, we offer precise CryoPen cryotherapy to help safely and effectively manage porokeratosis lesions. Our sophisticated cryotherapy technology has been developed to target affected skin rather than surrounding healthy tissue, providing a less invasive solution if treatment is needed.
Porokeratosis is the name for a group of keratinisation disorders defined by raised edges and a threadlike border in normal skin texture around the edge of a central patch. These bumps are brown, red, or flesh-coloured, and they can be solitary or grouped. These bumps may be brown, red, or flesh-coloured and can be isolated or clustered.
There is no single known cause, but factors such as genetics, sun exposure and a weakened immune system are associated with the condition.
Many people with porokeratosis may not have symptoms beyond the appearance of lesions, but some experience dryness, itching or cosmetic concerns — especially in visible areas.
Cryotherapy is one of the treatment options used to help reduce or remove porokeratosis lesions, especially when they are bothersome or persistent. With very low temperatures, cryotherapy helps destroy the skin lesion, and your body’s natural healing process will then remove it.
Benefits of Cryosonic’s Cryotherapy approach:
❄️ Localised and controlled: Only the targeted lesion receives freezing, sparing healthy skin from damage.
Cryotherapy may be recommended alongside other options, depending on the size, location and number of lesions, as well as your specific concerns and goals.
What causes porokeratosis?
Porokeratosis is believed to be caused by abnormal keratin production in skin cells. Factors such as long-term sun exposure, genetics and immune system changes play a role.
Is porokeratosis dangerous?
Most forms of porokeratosis are benign, but some types carry a small risk of developing into skin cancer over time—most commonly squamous cell carcinoma — especially if left untreated or if the lesion changes in appearance. Regular monitoring and sun protection are important.
Will the lesions go away on their own?
There’s no cure for porokeratosis. In mild cases, lesions may be observed without intervention, as they may remain stable for years. However, if the lesions are symptomatic (e.g., leukoplakias) or enlarging or cosmetically bothersome, treatment may be considered.
Does cryotherapy hurt?
Cryotherapy is generally well-tolerated. During treatment, you may feel a brief cold or stinging sensation. Most clients find the procedure comfortable, and discomfort usually subsides quickly.
How many treatments will I need?
Treatment plans vary based on the size and number of lesions. Some clients notice improvement after a single session, while others may benefit from additional visits. Your clinician will tailor a plan that’s right for you.
Can the lesions come back?
Porokeratosis is often chronic and recurrent. After one has been treated, not uncommonly others will develop, and continued sun exposure or an underlying disease process may lead to new ones.
Any other way to minimise the risk of new lesions?
To help manage porokeratosis:
No being in the sun for too long; keep SPF full-spectrum on at all times.
You should wear protective clothing in bright sunlight.
If the size, colour or texture changes, schedule regular skin checks.
