There are many methods to detect the skin health, skin surface properties, skin color, skin color type, and hair conditions. They are non-intrusive.

Microphotography and image
Use high-quality macrophotography—images to analysis the surface of skin.
Various modes of lighting–tungsten, halogen, fluorescent, UV, and cross and parallel polarized light–can all be used. The option of the right lighting depends on the experience of obtaining the best images for analysis.
Spectrofluorimetry is a valuable tool to characterize fluorescing constituents, or fluorophores, in the skin. Fluorescence bands may originate from the amino acids tryptophan, tyrosine, and phenylalanine (excitation between 280 and 295 nm), as well as cross-links in collagen (335 and 350 nm) and elastin (360 and 370 nm). Irritation, aging, and photoaging have been associated with alterations in the fluorescing patterns of these intrinsic fluorophores in skin. Therefore, spectrofluorimetry may be applied to product evaluation and claim support studies.

Structure of skin
Ultra sound
Use 10MZ-50MHZ sound to detect skin conditions.

75.The relations of UV light and the molecular in the skin

The relations of UVlight and the molecular in the skin How do light damage skin? Light consists of a spectrum of photons which contain energy that vary according to the wavelength.  The light interacts on the molecular and then changes their chemical structure or on the subatomic level by creating free radicals. Otherwise, not only UV light but also green, blue, and violet light can damage cells. A photon’s energy can be absorbed into the molecule which is then altered. As the absorption of energy, it can also result in electron changes with the generation of free radicals. A free radical is in fact simply an atom with an unpaired electron that starts up a destructive concatenation of chemical reactions. It may end up causing damage in the cell membranes or in the DNA of the cell. The following are the reaction after exposure to UVB, UVA, and blue light. The influence of increased free radical activity DNA strand breaks occur from increased free radical activity. W e

76.factors for skin damage(1)

There are many factors that cause skin damage. How does the damage result? They may be from the UV light, pollution , and so on. For example, photoaging and free radical. Then the cells are influenced.   photoaging Sunlight will cause phtoaging. Chronically irradiated skin is metabolically hyperactive, thus giving rise to epidermal hyperplasia and neoplasia , increased production of elastic fibers (solar elastosis), accelerated breakdown and synthesis of collagen , and enhanced inflammatory processes. If DNA damaged and a mutation occurs in the gene, the keratinocytes may lose their ability. Free radical and antioxidants Stratum corneum is frequently and directly exposed not only to UVR but also to other outside forces such as air pollutants, chemical oxidants, smoking, and microorganisms . They are the resources of free radicals . If the protection is insufficient, oxidative damage may occur . Then the chronic accumulation of such deviated cell components may result in t
