When it comes to light therapy, wavelength is incredibly important because light penetration dictates what light application works best for which skin treatment type.
While each light color has its niche use within skin therapy, infrared and visible light reach the same end. They aim to facilitate skin repair — often, but not always — predicated on boosting collagen.
According to a study, cited by the Journal of the American Academy of Dermatology (JAAD), “light therapy augments tissue repair and promotes regeneration and skin rejuvenation by naturally stimulating collagen production in the body.” We’ve cited various scientific studies on how light treatment affects specific areas of focus, from complexion to cell regeneration and muscle pain.
