Non-ablative Skin Rejuvenation
Connor Walsh
The Problem
•
•
•
Currently, millions of Americans are aggravated by
some type of skin defect such as a scar, a wrinkle, or
acne.
The medical term ablative refers to the surgical
removal of tissue from the body, and in the case of a
wrinkle, this tissue is usually from the face.
This can cause weeks of recovery and pain for the
patient.
Non-ablative Skin Rejuvenation
•
•
•
A non-ablative device is one that does not require the
removal of tissue and can be performed over the skin.
One such device is the LED light.
These lights can be used in all colors ranging along the
wavelength spectrum
Light Emitting Diode (LED)
•
•
•
•
An LED is a device that uses a diode to create light.
This diode acts as a valve that allows electricity to flow in one
direction.
Electrons move from an area that is highly compressed with
other electrons to an area that is not so compacted.
This movement causes an emission of light, and it’s strength
depends on the number of electrons allowed to move through
the diode.

How LED Healing Works
•
•
•
LED light therapy works by emitting
wavelengths that stimulate cellular
function in the layers of the skin.
This can be applied to many
different problems we see with the
skin such as aging, acne, and
scarring.
Different color LED lights have
different frequencies which are
used to heal many of these skin
impurities.
Wound Healing
•
Wound Healing
•
•
Red LED lights have shown to stimulate cell growth in the
dermis which have accelerated the healing process of
wounds.
This can also be useful when tissue engineering skin because
the light can help speed the growth process.
Acne Treatment
•
Acne Treatment
•
•
•
Red, blue, green, and violet LED lights
have all seen a positive outcome when
applied to patients with acne.
Combining red and blue LED lights have
also shown an increase in skin texture
and brighter skin tone as well as
reducing the amount of acne.
Some in home devices can cost up to
$500.
Limitations with Anti-Aging
•
Anti-aging
•
•
•
•
Blue LED lights have shown significant
improvements in reducing the effects of aging.
This has not been perfected however and is
still expensive and is therapist-intensive.
Cost ranges from $200 to $1000 for such
devices.
Blue LED’s are more expensive because they
require indium gallium nitride which is a
difficult material to come by.
Towards the Future
•
•
•
I predict that in the future there will be
a large increase of LED lights used as
medical devices.
Exposure to blue LED light has been
shown to aid in short-term arthritis
relief in the hands, and further research
of this could help provide more long
term relief.
Also, these non-ablative techniques will
replace traditional ablative techniques
because the methods are cheaper and
require no surgery to perform.
