The ingredients of cosmetics and skincare products_dermis

People care about the wrinkles on their face. The reasons that caused wrinkles is aging. So the cosmetic and skin care industry adds the ingredients to simulate the material in the dermis.
The ingredients of cosmetics are usually similar to the substances inside the skin due to easy absorption. The following is the ingredients of cosmetics and skin care products.
The macromolecule in dermis
l   Collagen
Collagens in human body exist in many different types. However, collagen in cosmetics should be hydrolyzed collagens for easy abortion in dermis. Only the low molecular weight of macromolecules could go through the gap of barriers and reach dermis.  
l   Elastin
It is water-soluble substances and full of Lysine.
l   Melanine
It consists of melanocytes and can prevent the UV.
l   Keratin
It is similar to the collagen that needs to hydrolyze to low molecular weight. Then it will interact with skin as amino acids. 
l   Mucopoly-Saccharides
One of famous mucopoly-saccharides is hyaluronic acid which is a water-soluble substance. It maintains the hydration of connective tissue and elasticity of skin. Otherwise, the high hydration can absorb 400 times of water. It is made of umbilical cord of human, crest of rooster, and the of trachea of calf.

71.UVA and UVB Sun protection factor

UVA andUVB Sun protection factor SPF is Sun Protection Factor. The number is determined experimentally indoors by exposing human subjects to a light spectrum meant to mimic noontime sun.   The SPF number only relates to UVB protection.  UVA is measured by the other definition.  UVA protection is not measured through SPF numbers.  PA is the Japanese measurement of sun protection. It is one of protection grade of UVA  . UVA is based on the Persistent Pigment Darkening (PPD) reaction reading at 2-4 hours of sun exposure.  PA is a protective level of strength to mark the three PA+, PA++ and PA+++. SPF(sun protection factor) Standard: ISO 2444: 2010 cosmetic sun protection test method in vivo determination of SPF (sun protection factor) Test by erythema Minimal dose: MED (minimal erythema dose) Process: exposure to the UV (wave length 290-400nm) Test skin type: type I~ III (ITA 0 >28 0 ) Duration: 16-24hrs after exposure UVA-PF (UVA protection factor)

79.The roles of Vitamin in skin

The roles of Vitamin in skin As we know, the chemical changes induced by exposure to sunlight, we should be able to design a cosmeceutical regime to combat photodamage and reverse its effects. Vitamin molecules are the options and have the functions of metabolism, antioxidant and preventing free radical. 1.       Metabolism Vitamin A controls the conversion of pre–matrix metalloproteinases secreted by keratinocytes and fibroblasts into active matrix metalloproteinases, but with a deficiency of vitamin A, UV irradiation stimulates the unimpaired release of metalloproteinases that then destroy collagen and the anchoring fibrils. Without vitamin A, the rete pegs become flattened. Lang erhans cells need vitamin A to function, but if the vitamin A is inactivated by light, then they cannot function properly and recognize cells whose DNA has been damaged. 2.       Antioxidant Deficiencies of vitamin C permit more free radical damage . The main action of vitamin C is as an
