What is cryotherapy?
It is a very popular therapeutic method. It consists in the use of special devices containing liquid nitrogen, a gas that at very low temperatures causes tissue damage (cryogenic burn). Depending on the selected freezing time, we control the extent of the tissue damage.
Where is it used?
It is used for a multitude of cutaneous lesions. Most often against warts and condylomas. Additionally, on actinic hyperkeratosis and small basal-cell epitheliomas. It has very good results on keloids and dark spots on the face, hands and body.
How is it performed?
By freezing the lesion using the special liquid nitrogen container. We feel as if an ice cube is touching our skin. At first we freeze and then feel a burning sensation. In a little while, a cold oedema (swelling) is formed in the treated area and on the next day a blister appears. During the first two or three days, the area is sensitive and then a scab (crust) is formed, which falls off in 7 to 20 days, depending on the depth of treatment.
Usually it is a very safe treatment with satisfactory aesthetic results. However, there may be erythema (redness) at first when the scab falls off followed by hypopigmentation or hyperpigmentation. Very rarely, a scar may form if the lesion is very big.
