Cryotherapy for Skin Tags, Warts & Skin Lesions: A Safe Non-Invasive Solution in Côte Saint-Luc

The Quiet Revolution in Benign Lesion Removal

For decades, the only way to deal with a stubborn wart, an annoying skin tag rubbing on a necklace, or a brown sun spot on the cheek was a trip to a dermatologist who reached for a scalpel, an electric needle, or — most painfully — a giant cotton swab of liquid nitrogen at -196°C that frosted everything in a three-centimetre radius. The result was effective but often disproportionate: a small lesion gone, but redness, blistering, depigmentation or a permanent mark in its place.

Today, at Réhabital in Côte Saint-Luc, we use a different generation of cryotherapy. The CryoProbe™ XP and FreezPen® devices deliver nitrous oxide (N₂O) at -89°C through a sub-millimetric jet — closer in shape to a fine pen tip than a spray. The applicator targets only the lesion. Healthy skin one millimetre away stays untouched. The result is a treatment that is faster, less painful, more cosmetic and, for the kind of benign lesions we treat, just as effective as classic dermatological methods.

This article walks you through what these devices can treat, what a session at Réhabital actually feels like, the healing timeline you should expect and why Liliana Ciocoi — our certified esthetician — is the person most of our Côte Saint-Luc clients see for these procedures.

What Is the CryoProbe™ XP?

The CryoProbe™ XP is a handheld, pen-shaped cryosurgery device manufactured in Belgium and licensed by Health Canada. Inside the cartridge: medical-grade nitrous oxide pressurized to liquid form. When the trigger is pressed, the gas expands through a precision nozzle and exits at -89°C, freezing a perfectly delimited circle the size of the applicator tip — typically 1, 2 or 5 millimetres.

Compared to traditional liquid-nitrogen spray cryotherapy, this matters for three reasons:

• Precision — the freezing halo on surrounding skin is essentially zero.
• Comfort — because nerves outside the lesion are spared, the sensation is dramatically milder.
• Cosmetic outcome — lower risk of post-inflammatory hyperpigmentation, depigmentation or scarring, which matters on the face, neck and décolleté.

Skin Tags (Acrochordons): The One-Second Lesion

Skin tags affect roughly 46% of adults. They appear in skin folds — neck, eyelids, armpits, under the breasts, groin — and tend to multiply with age, weight changes and pregnancy. They are completely benign, but they catch on jewellery, snag on razors and, frankly, bother people every time they look in the mirror.

For Liliana, skin tags are the most satisfying lesion to treat. A 1 mm CryoProbe tip is placed directly on the tag for one to a few seconds. The tag turns white, then within hours darkens and dries and within 7 to 14 days it falls off cleanly, usually without a trace. One session is almost always enough.

Warts: A Targeted Approach to a Viral Infection

Warts are caused by HPV (human papilloma virus) and come in several forms — common warts on the hands, plantar warts on the soles, filiform warts on the face and neck, periungual warts around the nails. They are notoriously stubborn because the virus lives in the lower layers of the epidermis, protected by thick keratin.

Cryotherapy works by freezing the infected cells. The cell membranes rupture, the immune system is alerted to the viral particles released in the process and the body finishes the job over the following weeks. At Réhabital we typically schedule warts in 2 to 3 sessions, three to four weeks apart, with success rates between 85 and 95% in our experience. Plantar warts on weight-bearing zones may need a fourth session and at-home keratolytic care between visits.

Molluscum, Cherry Angiomas, Milia and Other Common Lesions

The CryoProbe is also our go-to device for several other benign lesions our Côte Saint-Luc clients ask about regularly:

• Molluscum contagiosum — small pearly bumps caused by a pox virus, common in children and immunocompromised adults.
• Cherry angiomas — bright red dots from clusters of small blood vessels, almost universal after 30.
• Milia — tiny white cysts around the eyes and cheekbones that don’t respond to extraction.
• Seborrheic keratosis — waxy “stuck-on” brown patches that appear with age.
• Sebaceous hyperplasia — small yellowish papules with a central dimple, often on the forehead and cheeks.
• Small dermatofibromas — firm benign nodules, often on the legs.

Each of these has its own freezing time, applicator size and number of cycles. None of them require anesthesia or downtime.

What a Session at Réhabital Actually Looks Like

A typical CryoProbe appointment with Liliana lasts 20 to 40 minutes depending on the number of lesions. The sequence is consistent:

1. Dermoscopic assessment. Liliana examines every lesion with a magnifier and applies the ABCDE rule (Asymmetry, Borders, Colour, Diameter, Evolution). Anything ambiguous is referred to a physician before treatment. Cryotherapy is only ever performed on lesions that are clearly benign.

2. Skin cleansing with an antiseptic solution.

3. Treatment. The CryoProbe applicator is held against the lesion for 1 to 30 seconds depending on the type. You feel a sharp cold, then numbness, then a brief sting as the area thaws. Some lesions are treated with a single freeze, others with two freeze-thaw cycles for deeper effect.

4. Aftercare instructions. Sun protection, avoid picking, optional vaseline if the area blisters.

5. Follow-up planning. A control photo is taken and the next visit, if needed, is scheduled for 3 to 4 weeks later.

The Healing Timeline: What to Expect Day by Day

Healing is predictable and follows the same pattern regardless of the lesion type:

• Hours 0-6: redness, mild swelling, a feeling similar to a sunburn limited to the treated spot.
• Day 1-3: formation of a small blister or dark crust. This is normal and expected — it means the cellular destruction worked.
• Day 7-14: the crust dries and detaches on its own.
• Week 3-6: the new pink skin underneath matures and blends back into surrounding skin tone.

The most important rule: do not pick the scab. Premature removal is the single most common cause of mild scarring with cryotherapy.

Frequently Asked Questions

1. Does cryotherapy hurt?

Most clients describe only a brief cold or pinprick sensation lasting a few seconds. Because the CryoProbe is so precise, surrounding nerves are mostly spared and no anesthesia is needed.

2. How many sessions are needed?

Skin tags and small warts usually clear in one session. Common, plantar warts and molluscum may need 2 to 3 sessions, 3 to 4 weeks apart.

3. Will it leave a scar?

Scarring is rare with CryoProbe technology. Some darker skin tones may see transient pigment change that fades over weeks to months.

4. Can I treat lesions on my face?

Yes — the precision of the CryoProbe makes it especially well suited for the face, including the eyelids, nose and around the lips.

5. How do I prepare for the session?

Arrive with clean, product-free skin on the treated area. Avoid retinoids and acids for 48 hours before. Bring a list of any medications and a complete medical history.

6. Is cryotherapy covered by insurance?

Cryotherapy for benign aesthetic lesions is not covered by RAMQ or most private insurers. We provide a detailed receipt; some employer wellness plans reimburse a portion.
