Targeted FreezPen Cryotherapy

What Is Targeted FreezPen Cryotherapy?

Targeted FreezPen cryotherapy is a cutting-edge dermatological technique that uses a pen-shaped handheld device to apply liquid nitrogen at -196°C with millimeter precision directly onto benign skin lesions. Unlike traditional cryotherapy methods that use wide sprayers which can affect surrounding healthy tissue, the FreezPen delivers an ultra-fine nitrogen jet that targets exclusively the lesion, perfectly preserving the adjacent skin.

At Réhabital clinic in Côte Saint-Luc, we have adopted this latest-generation technology to offer our patients a skin lesion treatment that combines maximum efficacy with optimal comfort. The FreezPen represents a significant advancement in ambulatory cryosurgery, allowing treatment of an impressive variety of skin lesions — from common warts to brown spots, fibromas and skin tags — in a single quick session with zero downtime.

How Does Targeted Cryotherapy Work?

The scientific principle behind targeted FreezPen cryotherapy is based on controlled cellular destruction through freezing. When liquid nitrogen at -196°C contacts the skin lesion, ice crystals form rapidly inside the abnormal cells. These crystals cause rupture of cell membranes, leading to programmed cell death (apoptosis) of the lesion cells.

The process unfolds in several precise physiological stages. First, rapid freezing causes intracellular crystal formation. Second, the thawing phase allows crystals to recrystallize, causing additional cellular damage. Third, the immune system recognizes the damaged cells and activates a localized inflammatory response that cleans the treated area. Finally, surrounding healthy cells divide and regenerate new, healthy skin at the site of the former lesion.

What makes the FreezPen particularly remarkable is the size of its applicator tip. Available in multiple diameters (from 1 mm to 5 mm), it allows our certified aestheticians to choose exactly the size corresponding to the lesion being treated. A tiny 2 mm skin tag will be treated with a 2 mm tip, with absolutely no risk of freezing the surrounding skin. This precision is impossible to achieve with traditional spray cryotherapy systems.

Advantages of Millimeter Precision

The millimeter precision of the FreezPen offers considerable advantages over conventional cryotherapy methods. The first and most important is the preservation of healthy tissue. Traditional spray systems create a freezing halo that often extends 2 to 5 mm beyond the lesion, affecting normal skin and potentially causing scarring, depigmentation or post-inflammatory hyperpigmentation. The FreezPen eliminates this risk almost entirely.

The second major advantage is a significant reduction in pain and discomfort. Since only the lesion is exposed to extreme cold, nerve endings in surrounding tissues are not stimulated. Our patients in Côte Saint-Luc generally describe the sensation as a slight tingling or momentary cold pressure, far from the intense pain often associated with conventional cryotherapy.

The third advantage is accelerated healing. With less damage to healthy tissues, the healing process is considerably faster. Most of our patients see complete healing within 7 to 14 days for superficial lesions, compared to 3 to 6 weeks with traditional methods. This rapid recovery is particularly appreciated for lesions located on visible areas such as the face, neck and hands.

Types of Lesions Treated by Targeted Cryotherapy

The versatility of the FreezPen allows effective treatment of a wide range of benign skin lesions. Common and plantar warts respond excellently to targeted cryotherapy, with a success rate of 85 to 95% after one to three sessions. Skin tags (acrochordons), those small skin growths often found in the folds of the neck, armpits and groin, are eliminated in a single session of just a few seconds.

Brown spots and solar lentigines, caused by chronic sun exposure, are a frequent indication at our clinic. The FreezPen allows individual targeting of each spot with remarkable precision, without affecting the normal pigmentation of the surrounding skin. Seborrheic keratoses, those brownish, rough patches that appear with age, are also effectively treated.

Soft fibromas, molluscum contagiosum (common in children), milia, flat warts and certain small superficial vascular lesions are among the many conditions we treat daily at Réhabital. Our expertise allows us to adapt the freezing time, number of cycles and application pressure for each specific type of lesion.

The Treatment Protocol at Réhabital

Our targeted FreezPen cryotherapy protocol in Côte Saint-Luc follows a rigorous five-step process to ensure safety and efficacy. The first step is consultation and dermatological evaluation. Our certified aestheticians — Liliana — examine each lesion with a dermoscopic magnifier to confirm its benign nature and determine its characteristics (size, depth, vascularization, location).

The second step is treatment planning. Based on the type and size of the lesion, the aesthetician selects the appropriate FreezPen tip and calculates the optimal freezing time. For a 3 mm wart, the standard protocol is 2 cycles of 8 to 10 seconds with a 30-second thawing interval. For a 2 mm skin tag, a single 3 to 5 second cycle is usually sufficient.

The third step is the actual application. The aesthetician positions the FreezPen perpendicular to the lesion surface and activates the liquid nitrogen flow. The patient feels an intense but brief cold sensation. For multiple lesions, each one is treated individually with a sterilized tip.

The fourth step is immediate post-treatment evaluation. The aesthetician verifies that freezing has reached the necessary depth by observing the formation of a white halo (frost zone) on the lesion. If freezing is insufficient, an additional cycle is applied immediately.

The fifth step is the provision of personalized post-treatment instructions. Each patient receives a detailed guide on caring for the treated area: application of healing cream, SPF 50+ sun protection, signs to watch for and follow-up schedule.

Expected Results and Healing Time

After a targeted FreezPen cryotherapy treatment, patients observe a predictable sequence of skin changes. In the first few hours, the treated area may show redness and slight swelling — this is the body's normal inflammatory response. Within 24 to 48 hours, a blister or crust forms over the treated lesion. This crust is a sign that the cellular destruction process has proceeded correctly.

Over the following 7 to 14 days, the crust gradually dries and detaches naturally, revealing new, healthy skin underneath. It is crucial not to pick at the crust prematurely, as this could interfere with the healing process and increase the risk of scarring.

For deeper lesions such as plantar warts or thick keratoses, the process may take 2 to 4 weeks. In some cases, a second treatment session may be needed 3 to 4 weeks after the first for recalcitrant lesions. Our overall success rate for benign lesions treated with FreezPen exceeds 90%, a result that reflects our expertise and the quality of our technology.

Targeted FreezPen Cryotherapy for Greater Montreal Patients

Our FreezPen clientele is extremely diverse and reflects the demographic mosaic of Greater Montreal. We regularly treat professionals from Westmount who want facial keratoses removed before an event, families from Hampstead with children affected by molluscum contagiosum, NDG patients consulting for recurrent plantar warts, and downtown Montreal workers who appreciate being able to return directly to the office after a 15-minute session with no visible downtime.

Targeted FreezPen cryotherapy is particularly relevant in the Montreal climate. Long winters and intense summer sun exposure favor the appearance of solar lentigines on photo-exposed areas (face, décolleté, hands, forearms) — an ideal indication for the FreezPen. Treatment is preferably planned in fall or winter, when sun exposure is reduced, to minimize the risk of post-inflammatory hyperpigmentation and optimize healing.
