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

surface properties
Microphotography and image
Use high-quality macrophotography—images to analysis the surface of skin.
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.
