What is the name of the method used to permanently remove lashes from the eyelid margin by applying heat?

Cryotherapy
Electrolysis
Laser ablation
Excision

The correct answer is: Electrolysis

The method used to permanently remove lashes from the eyelid margin by applying heat is known as electrolysis. This technique involves using a small electric current to destroy the hair follicle, preventing future hair growth. It's commonly utilized for permanent hair removal, including eyelashes, due to its precision in targeting individual hair follicles. In contrast, cryotherapy involves extreme cold to destroy tissues, making it unsuitable for eyelash removal. Laser ablation utilizes focused light to remove or destroy tissue but is not specifically tailored to hair removal on the eyelid. Excision refers to the surgical removal of tissue, which is more invasive and not directed towards the thermal destruction of hair follicles like electrolysis. Therefore, electrolysis stands out as the most effective and targeted method for permanently removing lashes through the application of heat.
