During the oxidation process of the skin, a large number of free radicals will be produced. Appropriate free radicals can establish an effective defense system, but too many free radicals will accelerate cell aging, and various skin aging phenomena will appear, specifically on the face. Spots, dark yellow skin, wrinkles, sagging and other problems, and too many free radicals will directly damage cell proteins. After the protein is oxidized, the face will appear dull, and fine lines, wrinkles, etc. will appear. A condition of accelerated aging. So which natural antioxidants are worth trying, let's take a look.

What are the natural antioxidants?
1. Red pomegranate: The antioxidant components of red pomegranate extract are much richer than that of tea polyphenols. Therefore, in the past two years, many big skincare brands have also added red pomegranate extract to their skincare. The polyphenol content in it is much higher. When applied to red wine and cranberry, it can not only improve the oxidation of the skin but also effectively remove turbidity and restore the transparent skin.
2. Tea polyphenols: It is well known that tea has an effect on beauty and weight loss, but do you know that the tea polyphenols contained in tea leaves are good anti-oxidants. Tea polyphenols contain a variety of ingredients that can effectively remove free radicals. At the same time, It can also inhibit the oxidative reaction of the skin, so skincare products containing tea polyphenols are an excellent choice for anti-aging and anti-oxidation.
3. Vitamin E: The antioxidant history of vitamin E can be said to be relatively long, and it is also the most well-known! Its effect is to protect the protein components in cells, block the effect of free radicals on cellular proteins, and avoid the problem of facial relaxation caused by the increase of free radicals. Moreover, it can also effectively prevent the growth of pigmentation.
4. Grape seed: The reason why grape seed has such an outstanding antioxidant effect is that it contains quite a lot of anthocyanins! The antioxidant effect of anthocyanins is 50 times that of vitamins! Anthocyanins can not only prevent and reduce external damage to the skin but also effectively repair collagen and elastic fibers, helping to form double protection.
5. Isoflavones: Isoflavones, a common ingredient in soybeans, and the fermented products of soybeans are more common in skincare products. This ingredient not only has an excellent antioxidant effect, but it can also effectively restore skin smoothness, clear the absorption channel, and help the skin delay aging.
6. Astaxanthin: an ingredient with a strong antioxidant effect, which may directly surpass the first five! This is a carotene-like ingredient, which contains a potential photo protectant, which can effectively reduce the frequency of skin oxidation, thereby achieving the effect of clearing free radicals.
Why fight free radicals
To put it simply, in addition to free radicals generated by metabolism, external pollution such as ultraviolet rays and smog are also the main sources of free radicals. Free radicals are atoms or groups with unpaired electrons formed in the process of human metabolism or stimulated by the external environment. Because of the existence of unpaired electrons, free radicals are very active, just like a hedgehog covered with thorns, rampaging inside the human body, and will react with surrounding cells and tissues at any time, attacking DNA, RAN, proteins, and other normal body tissues.
Under normal circumstances, the human body has a system against free radicals, which can protect the body from free radical damage. However, with the increase of age, the free radicals in the body increase, the body's ability to resist free radicals declines, the generation and elimination of free radicals are out of balance, normal tissues are attacked and damaged by free radicals, their functions are damaged, and the skin begins to age.
What does antioxidant mean
Antioxidant refers to the abbreviation of antioxidant free radicals, English Anti-Oxidant. The human body continuously generates free radicals in the human body due to continuous contact with the outside world, including respiration (oxidative reaction), external pollution, radiation exposure, and other factors. Studies have shown that the human body's antioxidant system is a system with complete and complex functions comparable to the immune system. The stronger the body's antioxidant capacity is, the healthier it will be and the longer its life. More and more research shows that anti-oxidation is an important step in preventing aging because free radicals or oxidants can break down cells and tissues, affect metabolic function, and cause different health problems.
Cistanche has antioxidant and anti-aging effects
The total glucosides of Cistanche can significantly increase the activity of SOD in the brain and kidney tissue of mice, and the high-dose group can also increase the activity of SOD in the heart and liver tissue, and significantly reduce the content of lipofuscin and MDA in each tissue, which can effectively clear the various levels of lipofuscin and MDA. It is a kind of reactive oxygen radical and has a protective effect on DNA damage caused by OH radicals. Cistanche phenylethanoid glycosides have a strong free radical scavenging ability, higher reducing ability than vitamin C, scavenging 1,1-diphenyl-2-trinitrophenylhydrazine (DPPH) free radical and anti-lipid hyperactivity Its ability is higher than that of vitamin E, it can improve the activity of SOD in sperm suspension, reduce the content of MDA, and has a certain protective effect on sperm membrane function. Cistanche deserticola polysaccharide can enhance the activity of SOD and GSH-Px in red blood cells and lung tissue of experimental aging mice caused by D-galactose, and at the same time reduce the content of MDA and collagen in lung and plasma, and increase the content of elastin, which has a positive effect on DPPH. It has a good scavenging effect and has a good scavenging effect on superoxide anion, hydroxyl, DPPH free radicals, and singlet oxygen. It has a good antioxidant capacity and may become a drug for the prevention and treatment of skin aging diseases. The phenethyl glucoside monomer compounds have significant free radical scavenging activity and anti-lipid peroxidation effect, and it is found that the more phenolic hydroxyl groups in the molecule, the stronger the activity. It is believed that phenethyl glucoside compounds are the main active components of Cistanche. Phenylethanol glycoside compound salidroside has good free radical scavenging activity. And 2'-acetylverbasic glycoside>verbasidin>piperoside B>isoverascoside>echinacoside>cistanoside A. Echinacea has the ability to significantly scavenge DPPH free radicals and has the ability to scavenge reactive oxygen species and prevent free radical-induced collagen degradation.
