Your doctor will swab or spray a small amount of super-cold liquid nitrogen on the mole or skin tag. You might have a small blister where the mole or skin tag was, but it will heal on its own. Burning it off. An electric current passes through a wire that becomes hot and is used to burn off the upper layers of the skin. You may need more than one treatment to remove a mole. Skin tags are removed by burning through the narrow stem that attaches them to the skin.

Current as of: July 2, Cryotherapy is also a recommended treatment for actinic keratoses precancerous lesions on the skin and some forms of skin cancer. Any time that a lesion or tumor is exposed, and the extent of it can be easily determined, cryotherapy may be a good treatment option. Today, cryotherapy is even used on some internal cancers — such as liver cancer or prostate cancer — when the tumor is localized, large enough, and can be reached by the equipment during surgery.
Liquid nitrogen can be applied with a cotton swab to freeze and remove warts, moles, skin lesions and some skin cancers. However, in recent years doctors have begun using other liquid gases in cryotherapy treatments, including carbon dioxide, argon and proprietary mixtures from medical supply companies. In dermatology settings, where the treatment area is usually external and relatively small, the liquid nitrogen is often applied with a cotton swab or piece of foam. The goal is to freeze the tissue quickly and then allow it to thaw slowly, which destroys the skin cells.
Depending on the size of the treatment area, a second application may be needed. Additionally, your doctor may prepare the area by removing some of the tissue with a scalpel, or giving you a salicylic acid treatment to apply for several weeks beforehand. In other settings the liquid nitrogen may be sprayed on or circulated through a tube called a cryoprobe. When a cryoprobe is used to treat internal tumors, the doctor will typically use ultrasound or MRI technology to guide them.
After external cryotherapy treatment, the frozen tissue may form a blister and then forms a scab. Fluid may ooze from the wound for several days, and this is normal. The body naturally heals itself underneath the scab as usual, resulting in skin free from the blemish or lesion in question.
While patients will experience some pain at the time of treatment, the pain is generally small enough that local anesthetic is not required. Patients may take analgesics like ibuprofen or acetaminophen after the treatment. Cryotherapy is a minimally invasive procedure, and is often recommended over more intensive surgical options due to the minimal amount of time, pain and money involved. Plantar warts, which affect the bottoms of the feet, are one of the many common wart Read More.
Some moles can be removed using lasers. This is most commonly done with small, flat, non-cancerous moles. During laser removal, your doctor will use bursts of light radiation to destroy the mole tissue. To fully remove a mole using laser therapy, you may need to have two or three treatments.
Laser removal of moles can be a good option if moles are in hard to reach locations, like the ears, or on sensitive or highly visible areas of the skin, such as the face. Lasers can also be good for removing more than one mole at the same time.
Non-cancerous moles that live only on the surface of the skin can sometimes be removed by freezing them off. If you and your doctor decide freezing is the best method to remove your mole, your doctor will use liquid nitrogen to freeze it off. You may end up with a small blister on your skin where the mole used to be. Not all spots can be frozen, but warts and seborrheic keratosis a type of brown mole respond well to removal by freezing. Dermatologists not only tailor their approach to your spot, but they have access to a stronger freezing product.
This is especially important for a wart, because it needs to be frozen deeply, requiring a lot of energy and a strong product to remove it effectively. Freezing at home relies on a butane spray. The coldest temperature of that gas is about degrees below zero.
That means they have to spray the butane longer, which really hurts. The dermatologist uses liquid nitrogen, either spraying it on or dropping it on with a Q-tip. Essentially, it damages the spot quickly and severely so we can remove it.
But that also means people have to be very careful with the product. With a dermatologist, you get expertise and a more effective product to treat your spots.
