What is the CryoPen treatment for seborrheic keratosis?

A: The CryoPen treatment is a form of cryotherapy that uses a focused jet of ultra-cold nitrous oxide to freeze and destroy the benign lesion (seborrheic keratosis). Your body’s natural healing process then clears the treated cells.

Is the treatment painful?

A: Most patients report only a mild stinging or cooling sensation for a few seconds during the freeze, and minimal discomfort afterwards.

Will there be any downtime?

A: There’s little to no downtime. You may notice a scab or crust forming, minor redness or slight swelling, but you can usually resume normal activities straight away, with care.

How many treatments will I need?

A: Often, one session is sufficient for typical seborrheic lesions. However, some raised or thick lesions may need a follow-up session 4-6 weeks later to ensure complete removal.

Will the lesion come back, or will new ones appear?

A: The treated lesion should be removed permanently. However, because seborrheic keratoses can develop elsewhere naturally over time, new lesions may appear even if this one is treated. Additionally, new spots may go untreated, and the underlying predisposition persists.

Are there any risks or side effects?

A: Side effects are typically minimal; however, they may include temporary redness, swelling, blistering, crust formation, or changes in skin colour (lighter or darker), especially in darker skin tones.

Can any seborrheic keratosis be treated with CryoPen?

A: Most are suitable, but lesions that are very thick, irregular, changing rapidly in appearance, or suspicious in nature should first be assessed by a dermatologist. We perform a complete examination to ensure safe treatment. Cryopen is FDA-approved.

Will the treatment leave a scar?

A: Scarring is rare when performed correctly. Some temporary skin discolouration may occur, particularly in darker skin. Good aftercare and avoiding sun exposure help reduce risks.

How soon will I see results?

A: The frozen lesion will typically form a crust and fall off within about 1–2 weeks. The skin underneath gradually heals and normalises. Some aesthetic improvements are visible quickly; the full cosmetic result may take a few weeks.

What pre-treatment preparation is needed?

A: Ensure the area is clean and free from active sunburn or recent tanning. We’ll advise on any skin-care products to pause (e.g., strong retinols) and discuss your medical history in consultation.

Seborrhoeic Keratosis – Understanding Skin Growths and Treatment Options Croydon

Information about seborrhoeic keratoses, skin assessment and non-surgical treatment options

Seborrhoeic keratoses are common, non-cancerous skin growths that often develop as we get older. They can vary in colour, size and texture and may appear on different areas of the body.

Although confirmed seborrhoeic keratoses are harmless and usually don’t require treatment, some people choose removal if a growth catches on clothing, becomes irritated, or causes cosmetic concern.

At Lipo Sculpt, we provide information about non-surgical skin lesion treatments, including CryoPen cryotherapy for appropriately assessed, suitable benign lesions.

Important: Not every skin growth is suitable for cosmetic treatment. Any new lesion, changing lesion, bleeding without an obvious cause, or lesion that is difficult to identify should be assessed by a GP or appropriately qualified medical professional before considering cosmetic removal.

What Is Seborrhoeic Keratosis Croydon?

Seborrhoeic keratosis is a benign growth affecting the outer layer of the skin.

These growths become more common with age and may develop individually or in groups.

Typical characteristics include:

A light brown, dark brown, black or skin-coloured appearance.
A slightly raised, rough or waxy surface.
A distinctive appearance that can look as though the growth is attached to the skin.
Different sizes and thicknesses.
Occasional itching or irritation.

Seborrhoeic keratoses are not contagious and are not caused by the virus responsible for common warts.

Although they are benign, other skin conditions can look similar. Appearance alone should not be used to self-diagnose a skin growth.

Do Seborrhoeic Keratoses Croydon Need Removing?

Most seborrhoeic keratoses do not require treatment.

When a growth has been appropriately diagnosed as benign, removal may be considered for reasons such as:

Repeated irritation from clothing or jewellery.
Discomfort caused by friction.
Cosmetic concerns about the growth’s appearance.
Recurrent catching or rubbing.

Choosing not to have a confirmed benign seborrhoeic keratosis removed is also a reasonable option.

If a growth changes in appearance or develops unexplained symptoms, medical assessment should take priority over cosmetic treatment.

When Should You See Your GP?

Don’t assume every raised or pigmented skin growth is a seborrhoeic keratosis.

Arrange a medical assessment if you notice:

A new or changing pigmented lesion.
Rapid or unexplained changes in size, shape or colour.
Spontaneous or repeated bleeding.
Persistent inflammation, soreness or ulceration.
A growth that looks noticeably different from others on your skin.
Any lesion whose identity is uncertain.

Some skin cancers can resemble benign skin growths.

Where the diagnosis is uncertain, a GP or dermatology specialist may recommend further investigation, including dermoscopy or biopsy.

Lipo Sculpt does not use cosmetic cryotherapy to diagnose skin cancer or determine whether an uncertain lesion is benign.

Your treatment journey

Treatment Options for Seborrhoeic Keratosis

Several approaches can manage seborrhoeic keratoses. The best option depends on the diagnosis, lesion characteristics, medical history, and individual circumstances.


No treatment	Most confirmed seborrhoeic keratoses are harmless and can be left untreated.
Cryotherapy	Controlled freezing may be used for selected, confirmed benign lesions.
Curettage	A medical professional may remove a lesion using a scraping technique.
Shave removal	A medical professional may remove a lesion using a surgical shaving technique.
Dermatology assessment	Recommended where diagnosis is uncertain or specialist investigation is needed.

Lipo Sculpt does not offer every treatment. Medical or surgical options may require referral to an appropriate healthcare provider.

A considered approach

CryoPen Treatment for Seborrhoeic Keratosis

CryoPen uses a controlled application of very cold nitrous oxide to freeze targeted tissue.

Cryotherapy is an established approach for selected benign skin lesions, including certain seborrhoeic keratoses.

For an appropriately diagnosed and suitable lesion, freezing may damage the targeted tissue, which can subsequently crust and separate as the area heals.

However, treatment does not guarantee complete removal, and the outcome depends on factors including lesion thickness, size and location.

Some lesions may require additional treatment, while others may be unsuitable for this approach.

Risks and Possible Side Effects

Cryotherapy is not risk-free.

Potential side effects and complications include:

Temporary pain, stinging or tenderness.
Redness and swelling.
Blistering or crust formation.
Bleeding or infection.
Changes in skin pigmentation, including lighter or darker patches.
Scarring or changes in skin texture.
Incomplete removal or recurrence.
A need for further treatment.

Pigmentation changes may be more noticeable or persistent in some skin types.

The practitioner should explain relevant risks, limitations and alternatives before obtaining informed consent.

What Can CryoPen Treatment Involve?

1. Initial enquiry

Our team will ask about your skin concern, its location, and any relevant information needed to determine whether our service may be appropriate.

2. Assessment and suitability

Before treatment, we must confirm the lesion is benign. Medical assessment or confirmation may be required.

If the growth is suspicious, changing, or cannot be confidently identified, we will not proceed with cosmetic treatment and will recommend medical assessment.

3. Treatment, where appropriate

For suitable lesions, a trained practitioner may apply controlled freezing to the targeted area.

The procedure can cause temporary stinging, discomfort or a cold sensation.

4. Healing and aftercare

Following treatment, the skin may become red, swollen, blistered or crusted.

The treated tissue may gradually separate as healing progresses. The healing period varies between individuals.

5. Follow-up

Further review or treatment may be needed if the lesion does not respond as expected.

What Happens After Cryotherapy?

After treatment, the skin may appear darker or develop a blister or crust.

Healing varies depending on the area treated, the depth of freezing and individual skin response.

General aftercare considerations include:

Following the practitioner’s specific aftercare instructions.
Avoiding picking, scratching or deliberately removing crusts.
Keeping the area clean as advised.
Protecting healing skin from unnecessary friction.
Taking appropriate precautions against sun exposure.
Seek medical advice if redness, warmth, swelling, discharge, significant pain, or other signs of infection increase.

Some treated areas may take several weeks to settle, and skin colour changes can last longer.

Your questions, answered

Frequently Asked Questions

These answers offer a starting point. Your consultation provides information specific to the treatment and your circumstances.

Are seborrhoeic keratoses cancerous?

A confirmed seborrhoeic keratosis is benign and does not develop into skin cancer. However, some skin cancers can resemble seborrhoeic keratoses, so uncertain or changing growths should be medically assessed.

Can seborrhoeic keratosis disappear naturally?

Most seborrhoeic keratoses remain on the skin once they develop. They may change gradually over time, and new growths can appear.

Is CryoPen treatment painful?

Some people experience temporary stinging, cold sensations or discomfort during treatment. Sensitivity varies, and we can’t guarantee a pain-free experience.

Will one treatment be enough?

Some suitable lesions may respond to a single session, while others may require further treatment. Complete removal cannot be guaranteed.

Can seborrhoeic keratoses return?

A treated lesion may persist or recur, and new seborrhoeic keratoses may develop elsewhere on the skin.

Can CryoPen leave a scar?

Yes. Although not everyone develops a scar, scarring and changes in skin colour or texture are recognised potential complications.

Can CryoPen treat all seborrhoeic keratoses?

No. Suitability depends on the confirmed diagnosis, lesion characteristics, skin type, location and medical history. Some lesions are better managed by a medical professional using another method.

Can treatment be carried out at home?

Lipo Sculpt offers selected mobile, home-based treatments where appropriate. Availability depends on location, practitioner assessment and whether the procedure can be carried out safely in the proposed setting.

What if I am unsure whether my growth is a seborrhoeic keratosis?

Do not attempt to diagnose it yourself. Arrange an assessment with your GP or an appropriately qualified medical professional before considering cosmetic removal.
