Cryotherapy (also known as cold therapy or freezing treatment) is a dermatological procedure that applies extreme cold, typically via liquid nitrogen or carbon dioxide (CO₂) snow, to destroy abnormal tissue.
Common Dermatological Uses:
Wart removal (viral and common warts).
Molluscum contagiosum (a viral skin infection).
Sun-induced pigmentation (e.g., age spots, solar lentigines).
Seborrheic keratosis and actinic keratosis (precancerous lesions).
Skin tag (acrochordon) removal.
Early-stage skin cancers, such as superficial basal cell carcinoma.
Keloid management (to reduce scar tissue).
Procedure Overview:
A specialized spray device or probe delivers controlled cold directly to the lesion.
Treatment duration and number of sessions depend on the lesion’s type, size, and depth, as determined by your dermatologist.
Advantages:
Quick, in-office procedure with minimal downtime.
High efficacy for superficial lesions.
Short healing time; most patients resume daily activities immediately.
Possible Side Effects:
Temporary burning, redness, or swelling at the treatment site.
Rarely, blistering may occur.
Proper aftercare (e.g., keeping the area clean) minimizes risks.
Why Cryotherapy?
This method is ideal for precise, non-invasive removal of benign or precancerous growths. Its controlled application spares surrounding healthy tissue, ensuring both cosmetic and therapeutic benefits.
Important Note:
Cryotherapy must be performed by a dermatologist to ensure safe, effective outcomes tailored to your skin’s needs.
