Current ultraviolet light laser treatments can kill micro-organisms - but cannot be used in humans as they would also damage cells in the body.
Although several light and laser therapies have FDA approval as medical devices to treat acne, no true photodynamic acne therapy, combining photosensitizer and light, has been approved.

It will have to be an insulator and to be transparent to the relevant laser light.
They used intense nanosecond pulses of laser light to turn the metal's lustrous surface a deep black.
In the researchers' new imaging system, a beam of infrared laser light is widely dispersed throughout a room.

This generates the coherent light of a laser beam in the core of a long, thin optical fibre.
The process involves slathering on a carbon-based lotion, which absorbs the laser light and damages the hair follicles.
To measure the energy in question, he used two successive pulses of laser light, each 250 attoseconds long.
"It is not trivial to make the necessary amount of laser light at a specific wavelength, " Robicheaux said.
Such intense lasers are better suited to power-beaming because the cells that collect the laser light can be smaller.
This little miracle involves using tiny chip-mounted diffraction gratings and laser light passed over them via a scanning mirror.
The laser light dims within seconds when the plastic comes into contact with even the tiniest emission of vapour.
In 1997 he shared the Nobel Prize for physics for his work on cooling and trapping atoms using laser light.
On the Newt 2012 sign hanging above the double doors is a make shift laser light show blinding Newt out.

The team used a prototype to demonstrate the idea, hiding centimetre-scale objects illuminated with polarised green or red laser light.
By firing co-ordinated beams of laser light through the BEC, Hau and colleagues have slowed light down to a crawl.
Once the rods were in place, the team fired a burst of laser light in the general location of the tumour.
Scientists have for the first time created laser light using living biological material: a single human cell and some jellyfish protein.
Recording the blips also requires sending this gathered-up light through microscope lenses to filter out rival light from the laser itself.
The high average power infrared Free Electron Laser (FEL) provides intense beams of laser light that can be tuned to atmosphere-penetrating wavelengths.
The wavelength of the laser light can be tuned to interfere only with u-235 and "excite" the molecules, raising their energy level.
This past New Year's Eve, an event planning company hosted a black-tie bash onboard that included live music, fireworks and a laser light show.
