Cryosurgery or cold surgery is an effective treatment for many skin conditions. The most common indications for cryosurgery are acne, warts, corns, keratoses, precancers and cancers.

Liquid nitrogen is applied with a cotton-tipped applicator, or sprayed on the skin. It does not leave a linear scar, but may leave a white sport. It is relatively painless. Depending on the amount of freezing required, a tingling, burning, or cold sensation will be felt for a few moments.

After liquid nitrogen cryosurgery, the skin sometimes turns red, becomes dry, and may peel. This is normal. A blister may form in a few hours or days after treatment. If it fills with fluid or becomes uncomfortable, puncture the side of the blister with a clean needle. You may wash, shower, swim, and apply cosmetics as usual after treatment. If you get sun to the treated areas, they may become darker than the surrounding skin temporarily. To prevent this, specific sunblocks or bleaching preparations may be prescribed.

For many skin conditions, one cryosurgical treatment is sufficient. With acne and warts, regular or repeated treatments may be required.

If you have any questions concerning your cryosurgery, please call the office.
