LLLTH IS THE PART OF FOTOTHERAPY
•FOTOTHERAPY:
•1/ UV- ONLY UVA/HASTEN SKIN AGING, INDUCES PRODUCTION OF VITAMIN D, ACTIVATE  MELANOCYTS/
• UVB and UVC-CANCER. EFFECT –IONISATION!!
•2/ VISIBLE LIGHT: 400- 700nm
•3/ INFRARED LIGHT/ CUTANEOUS VASODILATATION, INCREASE METABOLISM, PAIN CONTROL

1/ MONOCHROMATICITY
•LASER EMITES ONLY ONE WAVELENTH                light bulb

LASER GLASSES
•EVERY patient , doctor , fysioterapeut, parents must have special glasses, because our eye is
1000x sensitive on laser beam.
•
•Glasses are: absorbing laser beam or reflexive laser beam.
