Answer

Cryotherapy

Cryotherapy entails liquid nitrogen applied topically and may be useful for small facial lesions less than 1 cm in dimensions. It induces response in more than 85% of cases. Cryotherapy has the advantage of short duration, minimal discomfort, and ability to be used repeatedly and in combination with other forms of treatment. [31]  Cryotherapy may cause skin hypopigmentation. It has limited penetration and is not ideal for large, deep lesions.
