The skin is composed of three-tier structure: epidermis, dermis and subcutaneous fat. The dermal layer contains collagen and elastin. They support skeleton of the skin with other fibers. These elements make the skin look smooth and young. These same elements are also vulnerable to UVA and UVB damage.
UV is divided into the long-wave UVA and short-wave ultraviolet rays of UVB. UVA this UVA wavelength long, can reach the dermis layer, the main damage of collagen, the support of the skeleton of the epidermis disappeared, leading to the formation of epidermal uneven collapse of such wrinkles, UVB rays are mainly role in the epidermis, resulting in sunburn or the deposition of melanin, the formation of black spots or skin. Ultraviolet UV situ reactive oxygen species and matrix metalloproteinases, these factors are the root cause of wrinkles, because they destroyed the collagen matrix of the dermis layer.
Fortunately, the skin's own repair mechanisms are able to rebuild the damage collagen, however, if the sabotage activities of reactive oxygen species and matrix metalloproteinases is not effectively controlled, they will continue to harm this collagen thus a serious impediment to the skin's own repair process. Cosmetic raw material astaxanthin can significantly weaken the ROS and NMP on the dermal layer of collagen, elastin destruction, to ensure the normal metabolism of the skin. If topical shrimp astaxanthin combined with oral administration of astaxanthin, to add some food rich in collagen, the repair of the wrinkles will be quickly.
Astaxanthin is known as its unique molecular structure, the absorption peak of its substance is about 470nm, with similar UVA wavelengths, so the small amount of astaxanthin can absorb a large amount of UVA, just like on Earth the most perfect and unique natural sunscreen, as the natural anti parasol blanket body, efficient protection against ultraviolet radiation, quenching of UV-induced free radicals, reduce UV damage to the skin to prevent. In addition, it can also quickly recover subjected to ultraviolet light burns damage the skin.
Astaxanthin antioxidant activity, anti-tumor and strengthening the immune system of many important physiological and biological functions, and thus has broad application prospects in food additives, aquaculture, cosmetics, health products and pharmaceutical industry. The international community has approved the synthetic trans astaxanthin pigment used as the additive of the aquaculture. But now the price of astaxanthin on the market is high, the price of synthetic products from 2000 to 2500 U.S. dollars / kg. Therefore, research and development of astaxanthin has important commercial and economic value.
With the development of aquaculture, food and pharmaceutical industries, in recent years, China's demand for foreign shrimp astaxanthin is increasing. The astaxanthin content extracting from the aquatic products is low. Meanwhile, the cost is also high. It can not meet the large-scale commercial production needs. So the development and use of astaxanthin will have broader market prospects.Source:http://www.cosprm.com
The application of tungsten in various industries
Steel Industry Most of tungsten applied in the production of special steels. The widely used high-speed steel was containing 9-24% of tungsten, 3.8-4.6% of chromium, 1-5% of vanadium, 4-7% of cobalt, 0.7-1.5% of carbon.
Magic effects of coconut oil
According to records, coconut oil can be regarded as the nobility of skin care plant extracts. It was rich in exotic tension of tropical plants, which can enhance the contractile force of the pores, perfectly beautify and nourish the skin.
