How
is LED Phototherapy Different from Laser Therapies?
LEDs
are manufactured to give a very narrow range of high intensity
light. Unlike lasers a large number of types are available, with
different wavelengths, intensities and optical properties.
Laser
Equipment
- Laser
energy output is much more powerful than LED, requiring substantial
time and commitment to training.
-
Lasers are available in a limited number of wavelengths and configurations.
- Generally
laser output devices are small, comparable to wands in coverage.
- Many
laser treatments depend on some form of partial or permanent thermal
energy to the underlying tissue.
- Many
laser treatments must use pulse control to avoid serious damage
to skin tissue.
LED
Equipment
-
LED phototherapies depend on changing the function of molecules
used in critical cellular functions by virtue of their unique
light absorbance signatures.
- LED
equipment generates 1 - 20 joules/cm2.
-
There are no known side effects on skin tissue due to over exposure.
-
LED phototherapies employing lower wavelengths (<500 nm) should
be used in conjunction with eye protection for both client and
operator.
- Do
not require extensive cooling, or electronic control
- Are
more compact and portable
- Require
less training to use
- Safer
for client and operator
- More
affordable
