Melanin is the chemical that makes our skin dark. Melanin absorbs in very well in the UV, but when one does so, the solution/molecule gets very hot.

Is there a way to photodissociate melanin without heating it, for example with some pulsed lasers, or some pulsed LEDs? Maybe a combination of two different wavelengths can do the trick?

  • $\begingroup$ Do you want to break down melanin directly inside the skin of a living human? Or do you have a sample of pure melanin on a surface? $\endgroup$ – patta May 3 '19 at 9:19
  • $\begingroup$ I am thinking of a sample above all, but I would also be interested in the skin situation. $\endgroup$ – bernd May 3 '19 at 9:40
