Common Antioxidants In Cosmetics

With the age increasing, the body protection is decreased. Physiological damage caused by lipid peroxidation, especially reactions that endogenous superoxide free radicals in the body in the unsaturated fatty acids, resulting in unstable lipid peroxidation, and thus the decomposition of aldehydes, especially malondialdehyde aldehyde, which attacks phospholipids and proteins by the reaction to form lipid-protein complex, lipofuscin deposition in the cell, as a sign of cellular aging. Therefore, prevention and anti-oxidant has been a powerful tool for the treatment of skin aging, but also an important way for many other compounds to achieve anti-aging skin effect.
Are commonly used antioxidants include substances such as enzymes or enzymes of vitamin A, vitamin E, cysteine, ascorbic acid, superoxide dismutase, glutathione peroxidase, metallothionein, sulfhydryl papaya enzyme, coenzyme Q10 and so on. And some amino acids such as glycine, serine and salicylaldehyde with iron to form the condensation product 2: l complexes, inhibited by the reaction with hydroxyl radicals of iron-related, and can inhibit lipid peroxidation, also has anti- oxidation. Melatonin, estrogen and other hormones and is also related to reports.
Superoxide dismutase (SOD) is the most in-depth study of cosmetics, the most widely used anti-oxidants, contain copper, zinc, manganese and iron metalloenzyme, widely present in various tissues of organisms, is the only to specific antioxidant enzyme superoxide anion. SOD from cattle, pigs and other extracts of red blood cells, also from spinach, cabbage, prickly pear, yeast and bacterial extracts. Now know that at least Cu. SOD, Mn. SOD, Fe-SOD, Zn-SOD and EC-SOD in five different SOD. SOD activity of the enzyme used as a cosmetic ingredient as affected by many factors, such as short half-life in vivo residence time is short, usually only 6-20min: 32 000 molecular weight around easily through the stratum corneum and the cell membrane and has antigenic and so on. To address these negative factors, the major domestic use molecular engineering approach to heparin, polyethylene glycol, dextran, biotin and other water-soluble macromolecules to their non-active groups or the use of molecular modifications to increase its transdermal absorption of liposomes, etc. embedding the new carrier.
Vitamin E, C is the first cosmetic application of anti-oxidants, a natural antioxidant, and their main function is to reduce the damage of living cells with hydrogen peroxide, superoxide anion and hydroxyl generation. Main role: vitamin E can reduce eye burn of erythema, which may be due to removal of oxygen free radicals induced by UV radiation, the reason: vitamin C is unstable in aqueous solution, it is difficult to be absorbed through the skin. In a proprietary formula, vitamin C preparations added zinc and tyrosine (Cellex-C), topical, the vitamin C levels in the skin 20 times higher than normal, the depth of penetration into the dermis 500 U m, tretinoin from the anti- oxidation, can block ultraviolet UVA and UVB damage to the organization.
In addition, vitamin C is considered a cellular factor that can directly stimulate fibroblasts to produce collagen. Vitamin C is a necessary component of collagen metabolism. L-ascorbic acid-2-phosphate magnesium (VC-PMG) is another vitamin C preparations patented formula, which is more stable compounds have been used in Japan to pigmentation agent. In addition, the element germanium (Ge32) and certain herbal and marine extracts also has antioxidant effects reported.

Sunglasses The Reason to wear them

The history of sunglasses goes all the way back to Roman times. Sunglasses are a special kind of glasses that are nowadays designed in a way to provide shade to the eyes from bright sunlight that makes it difficult to see. The Sunglasses protect eyes from harmful ultraviolet rays (UVA, UVB) and make your eyes feel softer, lighter and comfort your eyes with soothing effect. The lenses of sunglasses are heavily coated in different colors so the world seems to become a little less bright, which can be a relief on very sunny days and the color of lenses also add value to the style. You can choose the color of lenses as per your requirement, trend, occasion and/or matching with the color tone of your skin. Nowadays the sunglasses are especially popular in the summer season and on beaches.

However, protection from bright sunlight is not the only concern for wearing sunglasses. Sunglasses nowadays are considered as fashion accessory that gives the personality a style. Besides addition of style people may also wear them to hide their eyes from others when they are upset, or on drugs, having eye-patches or dont want people to see their eyes for some other reason. As in the case of celebrities who dont want their photos to be taken, sunglasses provide a relief. Sunglasses have boasted the confidence of people who are visually impaired.

If you wear sunglasses at a place where there is no bright sunlight, you may not properly be able to see your footsteps and can get injured incase you fall, people may also react badly towards you, they may laugh or stare at you by thinking that you are just doing it because you are a poser who wants to make a fashion statement.

Medically Recommended:
Nowadays It is possible to get your prescription lenses fitted in the sunglasses that will not only correct your eyesight/vision like normal eyeglasses but will also protect your eyes from the sun at the same time. However the prescribed sunglasses can be expensive.

The medical reason to wearing sunglasses is that it reduces the risk of eye cancers and cataracts by protecting your eyes from the suns ultraviolet rays.

All cheaper models do not give protection from suns harmful UV rays so whenever buying a pair of sunglasses, make sure to check that they offer 100% protection. Because the sunglasses cause your pupils to widen as they do in the dark to ease in watching and broaden the eye vision, cheap sunglasses on the contrary uses lenses that are not fully coated and cause huge amounts of UV radiation to enter your eyes, therefore doing much more harm than good.
