In the skin care industry, everyone is not unfamiliar with the word "anti-oxidation". What exactly is antioxidant? In fact, it is anti-aging " free radical ", which is to put it bluntly "anti-aging".
Antioxidant
is actually the abbreviation of antioxidant free radicals. The human body continuously produces free radicals in the human body due to continuous contact with the outside world, including respiration, external pollution, radiation exposure and other factors. Scientific research shows that cancer, aging or other diseases are related to the generation of excessive free radicals, so studying antioxidant can effectively overcome the harm it brings.
is therefore antioxidant and is listed as one of the main research and development directions by health products and cosmetics companies, and is also one of the most important functional demands in the market.
Antioxidant is any substance that can effectively inhibit the oxidation reaction of free radicals when present at a low concentration. Its mechanism of action is that it can directly act on free radicals or be consumed indirectly, easily generate free radicals, and further prevent it from reacting.
While the human body inevitably produces free radicals, it also naturally produces antioxidant substances that resist free radicals to counteract the oxidative attacks of free radicals on human cells.
. Studies have proved that the human body's antioxidant system is a system with perfect and complex functions compared to the immune system. The stronger the antioxidant ability, the healthier it is, and the longer life will be.
free radicals
free radicals are also chemically called " free radical ". It refers to an atom or group with unpaired electrons formed by homogeneously cleavage of the molecule of the compound under external conditions such as light and heat.
. In a chemical reaction, or under the influence of external light, heat, radiation, etc., the covalent bonds in the molecule are broken, so that the shared electrons of become exclusive to , and ions are formed; if the result of division makes the common electrons belong to two atoms or groups, a free radical is formed.
Sunlight radiation, air pollution, smoking, pesticides, etc. in the external environment will cause the human body to produce more reactive oxygen free radicals, causing nucleic acid mutations, which is the root cause of human aging and disease. Reactive oxygen free radicals in the body have certain functions, such as immune and signaling processes.
But too many reactive oxygen free radicals will have a destructive effect, leading to damage to normal cells and tissues of the human body, thereby causing a variety of diseases, such as heart disease, Alzheimer's disease , Parkinson's disease and tumors.
