On Wednesday, the YouTube science channel Veritasium released a video that displays the effects of laser hair removal in slow motion.

The laser treatment is quite successful in removing hair because it targets a molecule in the hair known as melanin. During the treatment, the melanin consumes energy from short pulses of laser light, burning the hair to a crisp.
