Light therapy uses specific wavelengths of visible light to interact with tissues in the skin and underlying structures. Different wavelengths produce different biological effects.
In practice, both red light and blue light therapy may be used depending on the clinical goal.
Light therapy can be used as a standalone treatment or as an adjunct to other therapies, such as acupuncture or cosmetic treatments.
Red Light Therapy
Red and near-infrared wavelengths penetrate deeper into the skin and soft tissues.
These wavelengths are commonly used to support:
Blue light primarily interacts with the surface layers of the skin and is commonly used in dermatology.
Blue light therapy may be used to support management of:
Different wavelengths interact with cells in different ways.
Red light wavelengths may influence mitochondrial activity and cellular energy production, which can support tissue repair and recovery.
Blue light interacts with bacteria on the surface of the skin and may influence inflammatory pathways involved in acne.
Light therapy can be used in several ways depending on the treatment plan:
Treatment sessions typically last several minutes depending on the device and treatment area.
Most light therapy protocols involve a series of sessions over several weeks, allowing tissues to gradually respond to treatment.
Programs may include:
The number of sessions required varies depending on the concern being addressed and the individual's response to treatment.
