Visible red light, at wavelengths of 620-700nm, penetrates human tissue to a depth of about 8-10mm, while visible blue light (430nm-450nm) penetrates 3-5mm.

Skin layers, because of their high blood and water content, easily absorb red and blue light. This light is beneficial in treating problems close to the surface such as wrinkles, age spots, broken capillaries, wounds, cuts, scars, trigger points and especially infections.

Infrared light at 880nm penetrates to a depth of about 30-40mm which makes it more effective for deeper lying tissue. While red and infrared wavelengths penetrate to different depths and affect tissues differently, their therapeutic effects are similar.

The choice of wavelength depends on the condition being addressed. For example, acne responds well to red and blue while fine lines and wrinkles respond well to infrared and red.

Occasionally a client may be hypersensitive to red light so infrared and blue light will be used. New stretch marks respond well to infrared light.

Blue light on its own, is intensely calming and all treatments should finish with a period of blue light.
