Generally, the shorter the wavelength, the shallower the penetration into the skin. The skin tissue absorbs light with obvious selectivity.

The skin tissue absorbs different wavelengths of light differently, and most of the ultraviolet rays are absorbed by the epidermis. As the wavelength increases, the degree of penetration of light also changes. Infrared rays near the red light machine penetrate into the deepest layers of the skin, but are absorbed by the skin. The long-wave infrared (wavelength is 15~400μm) penetrates very poorly, and most of it is absorbed by the epidermis.
