What is Cryotherapy?
Cryotherapy involves the application of liquid nitrogen to specific areas of the skin. The intense cold freezes the targeted tissue, prompting the lesion to detach over time and enabling healthy skin to regenerate in its place. This treatment is ideal for a range of skin issues, such as common and plantar warts, seborrheic keratoses, and specific types of actinic keratoses. Cryotherapy is particularly effective for surface-level lesions and can be completed quickly during an in-office visit.
How Does Cryotherapy Work?
Preparation of the Treatment Area
The skin surrounding the lesion is carefully cleansed, and a protective barrier may be applied to safeguard nearby healthy tissue.
Application of Liquid Nitrogen
Using a small applicator like a spray device or cotton swab, liquid nitrogen is applied directly to the lesion. The intense cold rapidly freezes the targeted tissue.
Formation of a Blister
The freezing process causes a blister to form beneath the lesion. This blister eventually dries out, allowing the treated tissue to separate naturally from the skin.
Healing Process
Healing typically takes one to two weeks, depending on the lesion’s size and type. As the dead tissue detaches, fresh, healthy skin forms in its place. Cryotherapy is minimally invasive and involves little to no downtime, so most patients can resume daily activities immediately following the procedure.
Importance of Cryotherapy
Cryotherapy offers numerous advantages, making it a preferred treatment option for specific skin conditions:
- Effectively Removes Lesions: Treats benign growths like warts and skin tags with high success rates.
- Prevents Progression of Precancerous Growths: Addresses lesions like actinic keratoses, helping to reduce the risk of skin cancer development.
- Minimally Invasive: A quick procedure with no need for stitches, anesthesia, or extensive recovery periods.
- Minimal Scarring: Precise application minimizes the risk of scarring, preserving the surrounding skin’s appearance.
- Fast Recovery: Most patients experience rapid healing, making it a convenient solution for busy lifestyles.
- Cost-Effective: Provides an affordable alternative to more invasive treatments while effectively addressing skin health concerns.
