What are the thermal effects of laser light primarily affecting during hair removal?

The thermal effects of laser light during hair removal primarily target hair follicles. When the laser is applied to the skin, it emits a specific wavelength of light that is absorbed by the pigment (melanin) in the hair follicles. The energy from the laser converts into heat, effectively damaging the follicles while minimizing damage to the surrounding skin and structures. This focused thermal effect leads to a reduction or permanent removal of hair, as it disrupts the follicle's ability to produce hair.

In contrast, while the skin surface, nerve endings, and blood vessels may also be affected to some degree during laser treatment, the primary mechanism and goal of laser hair removal is to specifically disrupt the hair follicles. This targeted approach is key to achieving effective results in hair reduction or removal.
