Which type of light therapy is known to penetrate the deepest into the skin?

Infrared light therapy is recognized for its ability to penetrate deeper into the layers of the skin compared to other types of light therapy. This is primarily due to its longer wavelength, which allows it to reach the dermal layers and potentially even the subcutaneous tissue.

Infrared light effectively stimulates collagen production, improves circulation, and aids in the healing of deeper tissues, making it beneficial for a variety of skin conditions and for overall skin rejuvenation. While ultraviolet light can affect the upper layers of skin and has its own set of applications, it does not penetrate as deeply as infrared. Visible light has limited penetration as well, primarily affecting superficial layers. Luminescent light therapies, which may include various forms of LED treatments, typically also do not reach as deep. Thus, infrared stands out due to its unique penetration capabilities, making it the preferred choice for deeper skin treatments.
