Written Laser Hair Removal Practice Exam

What target chromophores is melanin used for in laser treatments?

1. Tattoo removal

2. Hair removal

3. Vision correction

4. Skin resurfacing

The correct answer is: Hair removal

Laser treatments use specific wavelengths of light that target certain chromophores in the skin or hair. These chromophores are responsible for absorbing the laser energy and converting it into heat, which can then be used to achieve different outcomes. In the case of melanin, it is primarily used for laser hair removal because the melanin pigments in hair follicles are able to absorb the laser energy and permanently damage the hair follicle without damaging the surrounding tissue. While laser treatments can also be used for tattoo removal and skin resurfacing (using different target chromophores), these options do not specifically involve targeting melanin. Vision correction typically involves the use of LASIK surgery to alter the shape of the cornea, and does not involve targeting melanin at all. Therefore, the correct answer is B.
