Definition: Expilator is a type of light source that emits an intense and highly concentrated beam of ultraviolet or infrared radiation. It is commonly used in medical applications such as laser surgery, photodynamic therapy (PDT), and optogenetics. Expilators are essential for the treatment of certain types of cancer, particularly those with tumors that are resistant to conventional chemotherapy or radiation therapy. They work by directing the radiation towards the tumor cells, causing them to undergo programmed cell death, thereby inhibiting their
