34-.Skin health_Skin temperature and PH

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

Skin health
Skin health_Skin temperature and PH

l   Skin temperature
1.          The normal skin temperature is around 320C
2.          The skin temperature depends on the blood circulation in the subcuties.
3.          You can use the professional device to measure skin temperature, but also can just use the    thermometer.
l   Skin PH
To detect skin hydrogen ion concentration

The skin is covered by an acid mantle, which is formed through secretion from the sweat and sebaceous glands.
The measurement of pH uses electrochemical interface processes. Changes in the potential of the electrode can be evaluated by determining the potential difference between this electrode and a standard electrode with constant potential. Otherwise, temperature can affect PH measurements.
The normal pH range of the acid mantle is from 4.5 to 6.5. 
The acid mantle provides skin protection via chemical buffering, detoxifying, and bacteriostatic functions. Significant changes in pH may give rise to bacterial invasion sensitization, and various forms of dermatitis.

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

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
