LED Light Therapy

Question 1

Medical condition treated with LED

Answer 1

Pain and inflammation
Wound healing
Radiation-induced dermatitis
Oral mucositis in cancer treatment patients
Jaundice
Brain and liver cancer
Diabetic retinopathy and neuropathy
Actinic keratosis and skin cancers

Question 2

What is LED

Answer 2

(Light-emitting diode) semiconductor that converts electrical energy into light energy released in the form of photons; skin cells absorb therapeutic light and use it as a source of energy to stimulate cellular function

Question 3

How LED works

Answer 3

Light energy (photons) — absorbed by cells — fuels metabolic processes — homeostasis, collagen, and elastin synthesis

Think: photosynthesis and solar energy

Question 4

Wavelengths: shorter vs longer

Answer 4

Shorter: less penetrating- blue
Longer: more penetrating- reds and infrareds

Question 5

Wavelength colors blue/green/amber and red

Answer 5

Blue: destroys bacteria
Green: reduces hyperpigmentation
Amber/red: helps build collagen, elastin, and other proteins; accelerates healing, reduces inflammation, and promotes circulation

Question 6

Types of aging

Answer 6

Intrinsic: individual physiology/genetics
Extrinsic: (85% of aging) sun exposure, ozone/pollution, stress and diet, smoking, and alcohol consumption

Question 7

LED light therapy indications

Answer 7

Signs of aging
Acne
Rosacea
Hyperpigmentation
Inflammation
Increase circulation
Minimize appearance of pores
Increase skin density
Better product absorption
Accelerates healing
Prevention of environmental damage

Question 8

LED contraindications

Answer 8

Light sensitivities
History of phototoxic reactions
Currently using photosensitizing medications
Cancer
Epilepsy
Isotretinoin (accutane) within six months to one year
Serious health conditions or pregnancy
