Why does the pedunculated architecture of acrochordons make them ideal for cryogenic ablation?

Skin tags are not flat lesions; they are attached to the skin by a narrow stalk (pedicle) that contains a small fibrovascular core. This structure allows cryogenic energy to be focused precisely at the attachment point. When the pedicle is frozen, blood flow is completely interrupted, and the lesion becomes biologically non-viable without affecting the surrounding dermis. This makes cryotherapy especially effective and predictable for skin tag removal.

How does nitrous oxide cryogenics differ from liquid nitrogen in tissue response?

Nitrous oxide reaches approximately –40°C, producing a controlled and shallow freeze. This temperature is sufficient to destroy fibrovascular tissue in skin tags but avoids the excessive depth and lateral spread associated with liquid nitrogen. The result is effective lesion destruction with reduced risk of deep tissue injury, scarring, or pigment disturbance.

What cellular events occur during freeze–thaw cycles in skin tag tissue?

During freezing, ice crystals form inside cells, rupturing membranes and organelles. As tissue thaws, osmotic imbalance causes further cellular collapse. This combination permanently damages fibroblasts and endothelial cells, ensuring that the tissue cannot recover or regenerate.

Why is endothelial injury more critical than fibroblast destruction in skin tag removal?

The survival of any tissue depends on blood supply. Even if some fibroblasts survive initial freezing, destruction of endothelial cells lining the capillaries prevents revascularisation. Without oxygen and nutrients, the tissue undergoes complete ischemic necrosis and detaches naturally.

How does CryoPen achieve selective pedicle necrosis without epidermal sloughing?

CryoPen delivers cold energy in a tightly confined area. The stalk reaches lethal temperatures, while the surrounding epidermis remains above the threshold for permanent damage. This prevents surface skin breakdown and allows healing without open wounds.

Why does CryoPen not trigger excessive inflammatory cascades?

Unlike heat-based treatments, cryotherapy causes cell death without protein coagulation or thermal diffusion. This limits the release of inflammatory mediators such as prostaglandins and cytokines, resulting in minimal redness, swelling, and discomfort.

What biomechanical changes occur in the stalk post-treatment?

After freezing, collagen fibres within the stalk lose structural integrity. As tensile strength decreases, the skin tag becomes mechanically unstable and detaches naturally through routine skin movement and friction.

Why is haemostasis inherent to cryotherapy for skin tags?

Freezing causes immediate vascular collapse and thrombosis within the pedicle before separation occurs. Because blood flow is already halted, detachment does not result in bleeding, unlike mechanical snip removal.

How does dermal thickness variation affect freeze penetration?

Pedicle tissue has low thermal mass and freezes rapidly, while the surrounding dermis absorbs heat and limits cold spread. This natural thermal buffering protects deeper skin layers and ensures controlled treatment depth.

Why do thicker pedicles sometimes require extended freeze duration?

Larger pedicles contain more connective tissue and a denser vascular network. A longer freeze ensures that cold penetrates the entire cross-section of the stalk, preventing partial survival and delayed detachment.

How does CryoPen preserve melanocyte viability in pigmented skin?

Melanocytes reside primarily in the basal epidermis. Because CryoPen targets the stalk rather than the epidermal surface, melanocyte populations in surrounding skin remain unaffected, reducing the risk of hypopigmentation or hyperpigmentation.

Why is scarring biologically unlikely after CryoPen skin tag removal?

Cryotherapy does not stimulate fibroproliferative wound healing or disrupt dermal collagen scaffolding. Instead, healing occurs through normal re-epithelialisation, producing smooth skin without fibrotic scar tissue.

CryoPen Treatment for Suitable Skin Tags

Skin tags are small, soft growths that commonly develop where skin rubs against skin or clothing, such as the neck, underarms, and other skin folds.

They are usually harmless, although some people choose to have treatment for cosmetic reasons or because they catch on clothing or jewellery.

At Lipo 360, we may offer CryoPen treatment for suitable skin tags following consultation and assessment.

We do not diagnose skin lesions. If a growth is new, changing, unusual, bleeding without an obvious cause, has not previously been assessed, or there is uncertainty about what it is, we may recommend that you speak to an appropriate healthcare professional before treatment.

What Are Skin Tags?

Skin tags are small, soft growths of skin that often hang from a narrow stalk.

They are commonly found in areas where there is friction, including the:

Neck
Underarms
Chest and skin folds
Groin area
Other areas where skin or clothing regularly rubs

Skin tags are generally benign. However, not every lump, bump or skin growth is necessarily a skin tag.

For this reason, we will assess the area before considering treatment. If there is any uncertainty about the identity or suitability of a lesion, we will not proceed with treatment and may recommend further assessment.

How Does CryoPen Skin Tag Treatment Work?

CryoPen is a handheld device that applies controlled freezing to a targeted area.

During treatment, the practitioner directs the CryoPen applicator at the skin tag while aiming to limit unnecessary exposure to the surrounding skin.

The treated area may change in appearance following treatment as the skin responds to the freezing process.

Individual responses vary. Some skin tags may require more than one treatment, and treatment does not guarantee complete removal.

Your Lipo 360 practitioner will explain what to expect and whether CryoPen is considered suitable for the area during your consultation.

What Happens During Treatment?

Before treatment, we will discuss the skin tag, the area being treated and relevant medical information to assess whether treatment is appropriate.

We then position the CryoPen applicator over the targeted skin tag and apply controlled freezing.

Treatment time will vary depending on factors including the size and characteristics of the skin tag.

You may experience sensations such as cold, stinging or discomfort during treatment.

Because every person and every skin lesion is different, your practitioner will discuss the proposed treatment and expected response with you individually.

What Can I Expect Afterwards?

The treated area may temporarily become red, swollen, tender or darker following CryoPen treatment.

The skin tag and surrounding area may also change in appearance as the area heals.

Healing times and treatment responses vary between individuals. Some skin tags may respond following one session, while others may require further treatment.

Your practitioner will provide appropriate aftercare advice following your treatment.

Possible Side Effects and Risks

CryoPen treatment can cause temporary effects around the treatment area.

These may include:

Redness
Swelling
Tenderness or discomfort
Blistering
Crusting or scabbing
Temporary changes in skin colour

Pigmentation changes or scarring may also occur.

We will discuss suitability and individual risk during consultation before treatment.

Who May Be Suitable for Skin Tag Treatment?

CryoPen treatment may be considered for adults with suitable skin tags who would like them treated for cosmetic or comfort-related reasons.

Treatment is not automatically appropriate for every skin growth or every individual.

Before proceeding, we will consider factors such as the appearance and location of the skin tag, your medical history and other relevant information.

If we are not confident that a lesion is a straightforward skin tag, or some features require further assessment, we will not treat it. Where further assessment is appropriate, we may recommend seeking advice from an appropriate healthcare professional before treatment.

Skin Tag Removal at Home

Lipo 360 provides a mobile treatment service in selected areas of the UK.

Where appropriate and subject to availability, your consultation and CryoPen treatment can take place in your home.

Treatment remains subject to consultation and suitability assessment. Offering a mobile appointment does not mean every skin lesion is suitable for treatment.

Skin Tag Removal FAQs

What is a skin tag?

A skin tag is a small, soft growth of skin. Skin tags commonly develop in areas where skin rubs against skin or clothing.

Although skin tags are usually harmless, other skin lesions can sometimes look similar. We do not diagnose skin conditions and will not treat a lesion if there is uncertainty about its identity.

How does CryoPen treatment work?

CryoPen applies controlled freezing to the targeted area.

The treated skin tag may subsequently change in appearance as the area responds and heals.

Results and healing times vary, and you may sometimes need further treatment.

Is CryoPen treatment painful?

People experience CryoPen treatment differently.

You may experience cold, stinging or discomfort while the area is being treated, and some tenderness may occur afterwards.

Your practitioner will explain what you are likely to experience before proceeding.

Will one treatment remove my skin tag?

Not necessarily.

The number of treatments required can vary depending on the size, location, and response of the skin tag.

Some may respond following one treatment while others may require additional sessions. Complete removal cannot be guaranteed.

Can CryoPen be used on every skin tag?

No.

Treatment depends on the location and characteristics of the skin tag as well as your individual suitability.

We will not treat a lesion if we are uncertain about its identity or consider treatment inappropriate.

Can skin tags come back?

Treating an individual skin tag does not prevent other skin tags from developing.

We cannot guarantee that a treated skin tag will not recur or that additional skin tags will not develop elsewhere.

What if I’m unsure whether it is actually a skin tag?

Do not assume that an unexplained skin growth is a skin tag.

If a lesion is new, changing, unusual, bleeding without an obvious cause, or you are unsure what it is, seek appropriate healthcare advice.

Lipo 360 does not diagnose skin lesions.

Considering Skin Tag Treatment?

If you have a skin tag that you would like to discuss, the Lipo 360 team can talk you through the treatment and assess whether CryoPen may be appropriate for you.

Treatment is consultation-led, and individual results can vary.
