Which hair removal method utilizes intense light to target hair follicle growth cells?

The method that utilizes intense light to target hair follicle growth cells is photoepilation. This technique involves the use of a light source, often broad-spectrum light or laser light, to selectively target the pigment in the hair follicles. The energy from the light is absorbed by the pigment, which generates heat and destroys the hair growth cells, leading to a reduction in hair growth over time.

While laser treatment is similar and also effective in hair removal, it specifically refers to a laser technology that emits light concentrated at a specific wavelength to focus on the hair follicles. Both methods can achieve effective hair removal, but photoepilation is the broader category that encompasses various light-based hair removal techniques, including both laser and intense pulsed light (IPL).

Electrolysis is a different method where an electric current is used to destroy the hair follicle, making it effective for permanent hair removal but not involving light. Threading is a manual technique that involves using a twisted thread to remove hair from the follicle, which also does not utilize light energy for hair removal. Hence, photoepilation is the correct choice in this context.
