Cold Laser vs. Class IV Laser: What's the Difference?

Cold laser therapy and Class IV laser therapy are both light-based therapies applied over the skin to soft tissue areas. The practical difference is power: Class IV lasers deliver more energy, which can shorten treatment times and cover larger areas.

What Is Cold Laser Therapy?

Cold laser therapy, also called low-level laser therapy, uses low-intensity laser or LED light applied over the skin. The name comes from the absence of heat: most patients feel nothing or only a mild warmth. It is a gentle, supportive therapy commonly used for localized pain and stiffness.

Because the energy is low, sessions may be longer or more frequent, and the treatment area is typically kept focused.

What Is Class IV Laser Therapy?

Class IV laser therapy uses higher-power laser energy than traditional cold laser devices. The added power can treat larger areas in less time, while still feeling like warmth rather than pain. It is delivered by a trained clinician with protective eyewear and clear protocols.

Both approaches aim to influence local tissue activity through light absorption, but the dose and delivery differ.

Which One Is Right for You?

The choice depends on the condition, the area treated and the plan your chiropractor builds around the examination. Some situations suit a gentle cold laser approach, while others call for the higher output of a Class IV device.

ChiroPrime Orlando uses clinical-grade laser equipment, including MedRay systems, as part of personalized plans that often pair laser therapy with chiropractic adjustments and rehabilitation. See the cold laser therapy page for more.
