Cryotherapy
Skin tags, age spots, and minor surface lesions can detract from a clear, even-toned complexion, often causing unnecessary frustration during daily routines. Cryotherapy offers a targeted, non-invasive method to address these benign skin growths with minimal disruption to your day. By applying extreme cold directly to unwanted tissue, this precise treatment helps clear localized imperfections so you can feel more confident in your skin.

What Can Cryotherapy Treat?
Skin Tags
Skin tags are small, soft, skin-colored or slightly darker growths that frequently develop in areas of friction, such as the neck, underarms, chest, and eye area. While completely harmless, they can snag on clothing or jewelry and become irritated. Cryotherapy targets the stalk of the growth, freezing the cells to gradually shed the tag.
Age Spots and Sun Spots (Solar Lentigines)
Prolonged sun exposure can cause melanin to accumulate in concentrated spots, resulting in flat, dark patches commonly seen on the face, hands, shoulders, and chest. Cryotherapy selectively breaks down the excess pigment in these superficial epidermal layers, allowing fresher, more evenly pigmented skin to surface as the area heals.
Seborrheic Keratosis and Benign Lesions
Flat or elevated non-cancerous growths, such as seborrheic keratoses, often appear as raised, brown, or black spots with a slightly textured or "stuck-on" surface. These lesions can feel rough and cosmetically bothersome. Targeted freezing breaks down the cellular structure of the benign lesion, allowing it to crust and naturally slough off over subsequent weeks.
Cherry Angiomas
Cherry angiomas are small, bright red papules created by an overgrowth of blood vessels near the surface of the skin. They are typically smooth and harmless but can be noticeable on the torso or extremities. Cryotherapy neutralizes the small cluster of blood vessels, causing the spot to darken, collapse, and fade over time.
Warts and Verrucae
Caused by localized viral infections in the top layer of the skin, warts can be stubborn and uncomfortable. Cryotherapy freezes the viral tissue and surrounding skin cells, triggering an immune response that aids in removing the benign lesion. Multiple treatments are often required for deeper warts.
Molluscum Contagiosum
Molluscum contagiosum is a common, benign viral skin condition that causes small, firm, dome-shaped bumps on the surface of the skin. Cryotherapy applies controlled cold energy to the individual bumps, destroying the virally infected cells and encouraging your body's immune response to clear the lesions.
Actinic Keratosis (Pre-Diagnosed Precancerous Lesions)
Actinic keratosis presents as rough, scaly, or sandpapery patches on chronically sun-exposed skin, such as the face, scalp, and hands. Because actinic keratoses are precancerous sun-damage lesions, they require prior clinical evaluation and diagnosis by a physician or dermatologist before cosmetic intervention. Once medically confirmed, localized cryotherapy may help freeze and clear these superficial abnormal cells.
What Is Cryotherapy?
Cryotherapy is a medical-aesthetic procedure that uses sub-zero temperatures to destroy targeted, non-cancerous skin lesions through controlled freezing. By applying an ultra-cold substance — typically liquid nitrogen or nitrous oxide — directly to the unwanted tissue, the water within the targeted cells freezes instantly. This rapid freezing creates ice crystals that disrupt the cellular walls, causing the lesion to break down naturally over the days following treatment.
The treatment utilizes specialized, narrow-nozzle delivery instruments that allow for pinpoint accuracy. This ensures that the extreme cold is applied strictly to the lesion itself, preserving the healthy surrounding skin and minimizing the risk of unwanted scarring or hypopigmentation.
While cryotherapy is exceptionally effective for a wide array of superficial epidermal concerns, it is strictly intended for benign (non-cancerous) growths. It is not suitable for dynamic wrinkles, structural volume loss, or undiagnosed pigmented lesions. A professional skin assessment is always required prior to treatment to ensure any spot targeted is safe for removal.
Benefits of Cryotherapy
Pinpoint Precision
How it works: Micro-applicators deliver the freezing agent directly to the lesion in controlled bursts.
What this may mean for you: Surrounding healthy tissue remains largely unaffected, reducing the risk of unnecessary skin damage.
Non-Invasive Procedure
How it works: The treatment relies on physical thermal destruction without incisions, sutures, or local injectable anesthesia.
What this may mean for you: You avoid surgical recovery risks, severe downtime, and structural scarring.
Quick In-Office Treatment
How it works: Freezing individual spots takes only a few seconds per lesion.
What this may mean for you: Appointments fit easily into a busy routine, often completed within 15 to 30 minutes.
Versatile Surface Application
How it works: The fine delivery tip can safely target small lesions across various body regions, including the face, neck, body, and hands.
What this may mean for you: Multiple concerns in different areas can often be addressed during a single visit.
Minimal Downtime
How it works: The micro-injury remains superficial, allowing the skin's natural repair mechanisms to handle recovery.
What this may mean for you: You can return to most regular daily activities immediately after your appointment.
Encourages Natural Cellular Turnover
How it works: Freezing triggers the body to slough off damaged tissue and regenerate healthy skin cells underneath.
What this may mean for you: The treated area clears naturally over 1 to 3 weeks, leaving smoother skin behind.
What to Expect
Consultation and Suitability Assessment
Your appointment begins with a thorough evaluation of the skin spots you wish to address. We assess the size, depth, and character of each lesion to confirm that cryotherapy is an appropriate option and to rule out any features requiring medical dermatology review.
Preparation
The skin around the targeted area is thoroughly cleansed and disinfected. No topical anesthetic is generally needed due to the speed of the application, though comfort measures can be discussed during your consultation.
What Happens During Treatment
A fine spray or tip applicator delivers the cryogen directly onto the lesion for several seconds. You will typically feel a quick, sharp freezing sensation followed by a mild stinging or burning feeling as the tissue thaws. Most individual lesions take less than 30 seconds to treat.
Common Temporary Effects and Downtime
Immediately after treatment, the area may appear red, slightly swollen, or raised. Over the next 24 to 48 hours, a small blister or dark crust may form over the treated site. This crusting is a normal part of the healing process and will naturally fall off within 7 to 14 days for facial skin, or up to 21 days for the body.
Aftercare
Post-treatment care focuses on keeping the area clean and protected:
- Wash gently with a mild cleanser and pat dry.
- Do not pick, scratch, or force off any crusts or scabs to prevent scarring and infection.
- Apply a broad-spectrum mineral sunscreen (SPF 30 or higher) daily to protect the healing skin from post-inflammatory hyperpigmentation.
- Avoid strenuous workouts, saunas, and hot tubs for the first 24 to 48 hours.
Is Cryotherapy Right for You?
Cryotherapy is generally suitable for healthy adults looking for a fast, targeted method to clear harmless skin imperfections without surgery. It is ideal if you have confirmed benign skin tags, age spots, or raised keratoses that irritate you or affect your skin confidence.
Treatment may need to be delayed or avoided if you have active skin infections, cold urticaria, Raynaud's disease, cryoglobulinemia, or a history of severe keloid scarring. Additionally, dark skin tones require careful evaluation, as freezing can temporarily or permanently alter pigment in the treated area (hypopigmentation or hyperpigmentation). All lesions must be evaluated prior to treatment, and any spot showing suspicious characteristics will be referred to a physician or dermatologist.
Frequently Asked Questions
While safe for most people, cryotherapy carries a higher risk of temporary or permanent lightening (hypopigmentation) or darkening (hyperpigmentation) on deeper skin tones. A personalized consultation helps determine if cryotherapy or an alternative modality is best for your skin type.
Most clients experience a momentary, sharp cold sensation followed by a mild stinging or aching feeling that lasts a few minutes after the thermal application. The discomfort is brief and well-tolerated without anesthesia.
There is no required bed rest or time off work. However, the treated area will form a dark spot or crust that remains visible for 1 to 3 weeks depending on the body location. You should plan around special events if the treatment area is on your face.
Many minor skin tags and shallow sun spots clear after one treatment. Thicker lesions or stubborn warts may require two or three targeted applications spaced 3 to 4 weeks apart to safely resolve without damaging surrounding tissue.
Cryotherapy is designed to minimize scarring by targeting only superficial tissue. When proper aftercare is followed — specifically avoiding picking at scabs and applying daily sun protection — the risk of scarring is low, though minor texture or color changes can occasionally occur.
Safety is our primary standard. If a skin spot displays irregular borders, multiple colors, rapid growth, or any characteristics associated with skin cancer, we will not perform cryotherapy and will advise you to consult a physician or dermatologist for a formal diagnosis.
