Actinic keratoses (often called solar keratoses) are rough, scaly patches that develop on the skin after years of exposure to ultraviolet (UV) light from the sun or tanning beds. These lesions most commonly appear on areas frequently exposed to the sun — such as the face, ears, neck, scalp, hands, and forearms — and are especially prevalent in fair-skinned individuals or those over 40.
Typical signs of actinic keratoses include:
These changes tend to occur in sun-exposed zones and may increase in number over time if UV exposure continues.
Because actinic keratoses can sometimes progress to a type of skin cancer, we recommend having any persistent or changing areas assessed by a clinician. Treating actinic keratoses early can reduce the chance of progression and help restore smoother, healthier-looking skin.
Cryosonic Poole use Cryopen cryotherapy — an exact freezing treatment that targets abnormal skin cells. It is a non-invasive approach:
Most patients require only one session per lesion, depending on the lesion’s size and body area.
What is Cryosonic Cryopen treatment?
Cryosonic Cryopen is an advanced form of cryotherapy that uses a jet of nitrous oxide to freeze and destroy abnormal skin cells. It allows highly controlled, targeted treatment of actinic keratoses while minimising damage to surrounding healthy skin.
How does Cryopen work for actinic keratoses?
Cryopen rapidly cools the actinic keratosis to extremely low temperatures, causing the damaged cells to break down. The treated area then naturally heals as the body sheds the damaged tissue and replaces it with healthy skin.
Why is Cryopen used instead of traditional liquid nitrogen?
Cryopen offers greater precision than traditional liquid nitrogen spray. It is particularly suitable for delicate or visible areas such as the face, scalp, ears, and hands, helping reduce discomfort, shorten healing time, and reduce the risk of scarring.
Is Cryopen treatment painful?
Most patients describe a brief cold or stinging sensation during treatment. Any discomfort is usually short-lived and settles quickly once the freezing stops. Anaesthetic is not usually required.
How long does Cryopen treatment take?
Treatment is expeditious. Each actinic keratosis usually takes only a few seconds to treat, and most appointments are completed within minutes, depending on the number of lesions.
How many sessions will I need?
Many actinic keratoses respond well to a single Cryopen treatment. However, some thicker or more persistent lesions may require a follow-up session. Your clinician will advise you during your consultation.
Is Cryopen safe for AK treatment on the face?
Yes, Cryopen is frequently used on the face and other sensitive areas because of its precision and controlled delivery. Your clinician will carefully assess the lesion to ensure it is appropriate for treatment.
Can actinic keratoses come back after Cryopen treatment?
Treated lesions are usually permanently removed. However, actinic keratoses develop due to cumulative sun damage, so that new lesions may appear elsewhere over time. Ongoing sun protection and regular skin checks are essential.
Do I need a biopsy before Cryopen treatment?
Most actinic keratoses can be diagnosed clinically. If a lesion appears suspicious or shows signs of possible skin cancer, a biopsy or referral may be recommended before treatment.
What aftercare is required following Cryopen treatment?
Aftercare is minimal. You’ll be advised to:
Keep the area clean and dry
Avoid picking or scratching
Protect the area from sun exposure
Use sunscreen once healed
Specific aftercare instructions will be provided following treatment.
Who is suitable for Cryopen treatment?
Cryopen is suitable for most patients diagnosed with actinic keratosis. During your consultation, your clinician will evaluate your skin, medical history, and the lesion itself. To ensure Cryopen is the best option for you.
