Ask Dr. Candy - What is the Difference Between Cold Laser and Red Light Therapy?
Sometimes, when families look into the purchase of a cold laser for home use, they ask me to explain the difference between cold laser and red light therapy. I admit, sometimes the terminology and definitions can be confusing.
The main difference is that red light therapy only uses wavelengths that are in the visible light spectrum. Cold lasers aka low-level lasers use types of waves that the human eye cannot see. This addition of energy from the infrared and far infrared spectrum allows better penetration through skin, hair, clothes, etc. to stimulate healing in deeper tissues of six inches or greater.
So, red light therapy is better suited for skin health and a cold low-level laser is better for healing under the skin.
The illustration below gives us a visual point of view of these spectrums.
