FreezPen Cryotherapy: Precise Skin Lesion Treatment in Montreal

FreezPen cryotherapy is a breakthrough in the aesthetic and dermatological treatment of benign skin lesions. At Réhabital clinic, located in the heart of Côte Saint-Luc, we use this Swiss precision technology to offer Montreal patients a fast, safe and nearly painless solution for treating a wide range of skin imperfections — without surgery or traditional liquid nitrogen.

Whether you're bothered by a stubborn wart on your hand, an age spot on your décolleté, or a skin tag under your arm, FreezPen cryotherapy removes the lesion in seconds, with millimetre precision and discreet healing. In this article, we explain in depth how FreezPen works, which lesions can be treated, what to expect during a session at our Côte Saint-Luc clinic and why this technology has become the preferred choice for patients across Montreal, Hampstead, Westmount, NDG, Snowdon and the West Island.

What Is FreezPen Cryotherapy?

FreezPen is a medical cryotherapy device that uses high-pressure nitrous oxide (N₂O) to reach temperatures of -89°C at the application point. Unlike traditional liquid nitrogen (-196°C) used in pharmacies or conventional medical offices, FreezPen offers millimetre-level precision, targeting only the lesion while completely preserving the surrounding healthy skin.

The ultra-fine applicator (1 mm to 8 mm) delivers a controlled jet of gas that destroys abnormal cells through intracellular crystallization. Healthy tissue around the lesion is neither burned nor damaged, dramatically reducing the risk of scarring, hypopigmentation, or post-treatment hyperpigmentation — a major advantage for patients with darker skin tones.

Who Performs FreezPen Treatments at Réhabital?

At Réhabital, FreezPen cryotherapy treatments are performed by Liliana, our certified medical aesthetician, who has extensive expertise in treating benign skin lesions and using precision cryotherapy technology. Liliana conducts a complete aesthetic assessment before every treatment to confirm the benign nature of the lesion, evaluate its depth and personalize the protocol for an optimal result without risk to your skin.

Her approach combines clinical rigor with aesthetic care: she takes the time to explain each step, answer your questions and support you throughout the healing phase. This expertise reflects the philosophy of our aesthetic care department, where every treatment is personalized.

What Lesions Can Be Treated With FreezPen?

• Warts (hands, feet, plantar, filiform, periungual)
• Age spots (solar lentigines) on face, hands, décolleté
• Skin tags (acrochordons) on neck, underarms, eyelids
• Seborrheic keratoses (rough brown plaques associated with aging)
• Molluscum contagiosum (common in children and immunocompromised adults)
• Cherry angiomas (small red vascular spots)
• Superficial hyperpigmentation
• Small benign dermal nevi (after evaluation)

Before any treatment, Liliana performs a thorough visual examination. For any suspicious, atypical, or evolving lesion, we systematically refer the patient to a dermatologist to rule out any pathology requiring biopsy. Safety always comes before aesthetics.

Why Choose FreezPen Over Traditional Liquid Nitrogen?

Absolute precision. The FreezPen applicator is only a few millimetres wide, allowing localized freezing without collateral damage. Liquid nitrogen sprayed in mist form, by contrast, can affect a much wider area than the targeted lesion.

Greater comfort. Patients describe a brief intense cold tingling lasting only seconds. Most don't require any local anesthesia, even for sensitive areas like eyelids or around the lips.

Fast healing. A scab forms within days and falls off naturally in 1 to 3 weeks, leaving smooth, even skin. Scarring risk is extremely low when the treatment is performed by an experienced professional like Liliana.

Suitable for all body areas. Face, neck, décolleté, hands, feet, back, scalp — FreezPen can be used anywhere, including traditionally difficult-to-treat areas.

What to Expect at Your Côte Saint-Luc Session

Here's what a typical FreezPen session at Réhabital looks like:

1. Initial consultation (10–15 min) — Liliana evaluates the lesion, reviews medical history, takes before photos and explains the protocol.
2. Area preparation — Gentle cleansing, disinfection. No anesthesia needed in most cases.
3. FreezPen application (5–30 seconds per lesion) — The N₂O jet is applied directly to the lesion. You feel intense cold for a few seconds.
4. Pause and second application if needed — For deeper lesions (plantar warts, thick keratoses), a second cycle may be performed.
5. Aftercare advice — Liliana provides written instructions and schedules a follow-up if needed.

A single session is enough in 60–80% of cases for skin tags, cherry angiomas and small sun spots. Warts, more resistant, often require 2 to 3 sessions spaced 3 to 4 weeks apart. Extensive seborrheic keratoses may need 2 sessions. Visit our FreezPen cryotherapy page for the full protocol.

Aftercare: What to Do and Avoid

The post-treatment phase is crucial for a flawless result. Here are Liliana's recommendations:

• First 24 hours: keep the area clean and dry, avoid makeup on the treated zone.
• Days 1 to 7: redness, a small blister, or a scab may appear — this is normal. Don't pick or pop.
• Weeks 1 to 3: the scab falls off naturally. Apply a gentle healing cream (such as Cicaplast).
• Following 4 weeks: SPF 50+ is mandatory on the treated area to prevent post-inflammatory hyperpigmentation.
• Avoid sauna, steam room, chlorinated pools and hot baths for 5 to 7 days.
• Avoid chemical exfoliants (AHA, BHA, retinol) on the area for 2 weeks.

To optimize healing, you can complement your treatment with a soothing LED session — read our complete guide to LED light therapy to understand how red light accelerates cellular regeneration after cryotherapy.

Is FreezPen Safe?

FreezPen is a CE-marked and Health Canada–compliant medical device, used by dermatologists and aesthetic clinics worldwide for over a decade. Published clinical studies confirm an excellent safety profile, with a very low complication rate when the treatment is performed by a trained professional.

At Réhabital Côte Saint-Luc, treatments are performed exclusively by Liliana, specifically trained on FreezPen. Our clinic follows all current hygiene and disinfection protocols. Patients with a history of coagulation disorders, autoimmune disease, severe Raynaud's, or cryoglobulinemia require prior medical evaluation.

How Much Does a FreezPen Treatment Cost in Montreal?

The cost of a session depends on the number of lesions and their size. An initial consultation with Liliana allows us to establish a personalized treatment plan and a transparent quote. For patients treating multiple lesions, package pricing is available. See our FreezPen Cryotherapy page for detailed pricing.

How to Integrate FreezPen Into a Global Aesthetic Routine

FreezPen pairs beautifully with our other aesthetic treatments. After removing a sun spot, for instance, a SharpLight SR laser skin rejuvenation protocol helps even out overall complexion and prevent new spots from forming. Patients seeking a complete anti-aging plan can also combine FreezPen with clinical microneedling or a chemical peel.

For patients living in surrounding neighbourhoods — Hampstead, Westmount, NDG, Snowdon, Mont-Royal, Saint-Laurent — Réhabital is easily accessible by car or public transit.
