What is Cryotherapy?
Cryotherapy is a technique that involves applying liquid nitrogen to a targeted area of the skin. The extreme cold freezes the tissue, causing the lesion to detach gradually and allowing healthy skin to regenerate in its place. Cryotherapy is a convenient treatment for a variety of skin concerns, including common and plantar warts, seborrheic keratoses, and certain actinic keratoses. It is especially effective for lesions that are located on the skin’s surface and can be performed in a quick, in-office visit.
How Does Cryotherapy Work?
- Preparation of the Treatment Area. The skin around the lesion is cleaned, and a protective barrier may be applied to avoid damage to the surrounding healthy tissue.
- Application of Liquid Nitrogen. A small applicator, such as a spray device or cotton swab, is used to apply liquid nitrogen directly onto the lesion. The liquid nitrogen immediately lowers the temperature of the targeted tissue, freezing it within seconds.
- Formation of a Blister. The extreme cold causes a blister to form beneath the lesion. Over time, this blister will dry and separate, naturally detaching the treated tissue from the skin.
- Healing Process. The healing process typically takes one to two weeks, depending on the size and type of lesion. As the blister and dead tissue fall away, healthy skin forms in its place.
Cryotherapy is minimally invasive, quick, and usually requires little to no recovery time, allowing patients to continue with their daily activities soon after treatment.
Importance of Cryotherapy
Cryotherapy offers several benefits, making it a widely chosen option for those dealing with specific skin lesions:
- Effectively Removes Lesions. Cryotherapy can treat a variety of benign lesions, such as warts and skin tags, with high success rates.
- Prevents Progression of Precancerous Lesions. Cryotherapy is particularly valuable for pre-cancerous growths like actinic keratoses, reducing the risk of these lesions developing into skin cancer.
- Minimally Invasive. The procedure is quick and minimally invasive, with no need for stitches, anesthesia, or extensive recovery time.
- Minimal Scarring. With precise application, cryotherapy typically results in minimal to no scarring, preserving the appearance of surrounding skin.
- Fast Recovery. Most patients experience a short healing period, making it a convenient treatment option for those with busy schedules.
- Cost-Effective. Cryotherapy is a relatively affordable treatment compared to more invasive options, providing an efficient way to manage skin health.
