skin color type_ITA
There are many methods to detect the skin health, skin surface properties, skin color, skin color type, and hair conditions. They are non-intrusive. The following is the method to figure out the skin color type. 

skin color type_ITA

Skin color type
1.  Fizpatrick skin types
Questionnaire designed by Dr. Thomas B. Fitpatrick in 1975.
Fizpatrick skin types
Type I       Celtic type                   0-150
Type II.    Caucasian white          50-250
Type III    Mixed type                 100-350
Type IV    Mediterranean type    150-500
Type V     Asian/ Indian skin      150-650
Type VI    Black skin                  600-999


2.  ITA0(individual typology angle) calculation

CIE colorimetry
=[Arc Tangent ((L*-50)/b*)] x 180/ π

Very light                  ITA0 > 550
Light                 400< ITA0<550
Intermediate      280< ITA0<410
Tan/matt            100< ITA0<280
Brown              -300< ITA0<100
Black                         ITA0< -300

76.factors for skin damage(1)

-
Image
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 i...

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....
