LLLT Lasers or Softlasers offer the strongest and most effective light therapy treatments. This is because their light is already coherent (photons are aligned) which is why laser light travels so far. However, Laser Light Therapy devices are more expensive than LED light therapy devices and cover a smaller area. Low Level Laser therapy cannot burn and are employed in wound healing, skin rejuvenation, collagen production, hair loss, pain management, healing etc.
