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.
