Cryotherapy is a method used in the treatment of various skin problems and lesions. This method aims to destroy abnormal tissue cells by freezing them. Cryotherapy, which is usually applied using liquid nitrogen, is effective in the treatment of skin lesions such as skin cancer measures, warts, skin tags, keratoses and some moles. Cryotherapy, which is considered a safe and effective treatment method in modern dermatology, is preferred because it is a minimally invasive procedure. In this section, we will present a guide that includes what cryotherapy is and answers to frequently asked questions.
What is Cryotherapy?
Cryotherapy literally means "cold therapy" and involves using low temperatures to freeze and destroy abnormal skin cells. Liquid nitrogen is the most commonly used freezing agent and can reach temperatures as low as -196°C.
