Normal skin has the ability to absorb light to protect the organs and tissues in the body from light damage. The ability of light to enter human tissue is closely related to its wavelength and the structure of skin tissue. Generally, the shorter the wavelength, the shallower the penetration into the skin. The skin tissue absorbs light with obvious selectivity. For example, the keratinocytes in the stratum corneum can absorb a large amount of short-wave ultraviolet rays (wavelength is 180~280nm), and the spinous cells in the spinous layer and the melanocytes in the basal layer absorb long-wave ultraviolet rays (wavelength is 320 nm~400nm). 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.
The above is the theoretical basis that the skin analyzer can be used to detect deep skin pigmentation problems. The skin analyzer uses different spectra (RGB, Cross-polarized light, Parallel-polarized light, UV light and Wood’s light) to create different wavelengths to find out skin problems from surface to the deeper layer, so wrinkles, spider veins, large pores, surface spots, deep spots, pigmentation, pigmentation, inflammation, porphyrins and other skin problems can all be detected by skin analyzer.
