A question was submitted by an attendee of our Laser Therapy webinar:
If there is no skin wound, is there an advantage to applying laser by direct contact versus indirect cone vs. ball?
I guess it would depend on what you were treating, but yes. Direct contact with the ball allows the light to penetrate deeper than the indirect cone applicator. With the direct applicator head you can actually push the blood away from the surface of the skin, allowing the light to go further. The indirect contact head doesn't need to do that as you are typically treating superficial wounds and don't need to go through multiple layers. The direct head with the ball on it is patented for the Companion lasers.
