Skin care effect of astaxanthin
1, the sunscreen effect of astaxanthin;
Because of its unique molecular structure, the absorption peak of astaxanthin is about 470nm, which is similar to the wavelength of UVA (380-420nm), so a small amount of astaxanthin can absorb a large amount of UVA, just like the most perfect and unique natural sunscreen on the earth, just like a natural umbrella covering the whole body, which can effectively prevent ultraviolet radiation, quench free radicals caused by ultraviolet rays and reduce the damage of ultraviolet rays to the skin. In addition, it can quickly repair the skin burned by ultraviolet rays. Experts from Rigano Institute of Dermatology in Rome concluded that astaxanthin has the best effect on protecting human epidermal fibroblasts from ultraviolet radiation.
2, astaxanthin freckle whitening effect:
Astaxanthin can effectively inhibit the production of melanin, the inhibition rate is as high as 40% (when the content of astaxanthin in skin reaches 10umol/L), and it can significantly reduce the precipitation of melanin, keeping you away from dull, colorless and spotted skin. Astaxanthin will make your skin more fair, beautiful, flawless and shiny. Its effect is far superior to arbutin, kojic acid, vitamin C and other whitening ingredients. So far, no substance has been found to have such a good effect of preventing melanin precipitation at the same concentration, so it is also known as the best raw material for whitening and freckle removal, and is used in high-end first-line cosmetics. Usually, when we make a mask, we can drop a drop of astaxanthin in the mask, and insist on using it will achieve good results.
3. Anti-wrinkle effect of astaxanthin:
Skin consists of epidermis, dermis and subcutaneous fat. The dermis contains collagen, elastin and other fibrous cells, which form the skeleton that supports the skin. It is these elements that make the skin look smooth and young, and these elements are also easily affected by UVA, UVB, ozone or other oxidation factors. When the collagen in the dermis is oxidized and broken for the above reasons, the supporting effect on the epidermis disappears, which leads to uneven collapse of the epidermis, resulting in wrinkles, and the skin becomes dull, loose and dry, and wrinkles such as fine lines and crow's feet appear. Therefore, the fundamental reason to prevent skin from being oxidized is not to eat collagen. Some experimental data show that oral collagen is ineffective because its molecular weight is too large to be absorbed. The most fundamental way is to resist oxidation. Astaxanthin is the strongest antioxidant found so far.
Health care function of anthocyanins on human body
● It can significantly increase high-density lipoprotein and reduce low-density lipoprotein (commonly known as bad cholesterol), and can prevent atherosclerosis and cardiovascular diseases.
● By directly protecting glomerular basement membrane, prevent free radicals produced by hyperglycemia, effectively inhibit diabetic nephropathy and destroy basement membrane; It can also resist the free radicals of renal tubular epithelial cells.
● It can effectively prevent retinal oxidation and photoreceptor cell damage, and protect the brain, eyes and central nervous system.
It has a strong activity of inducing cell division, plays an important role in immune regulation and can enhance human immunity.
Appropriate symptoms of astaxanthin
Protect eye health:
Tretinoin and the central nervous system (brain) are rich in unsaturated fatty acids, so the free radicals produced by oxidation can easily cause peroxide damage. Studies have shown that astaxanthin can easily pass through the blood-brain barrier and cell membrane, effectively prevent retinal oxidation and protect the central nervous system, especially the brain, thus effectively treating central nervous system injuries such as spinal cord injury, Parkinson's syndrome and Alzheimer's Harmo syndrome. In particular, the effect of macular degeneration is more significant than lutein.
Eliminate joint discomfort, pain and swelling;
The accumulation of free radicals in the human body will lead to oxidative damage, and then induce joint pain, swelling, weakness, noise, fifty shoulders and tennis elbow. Astaxanthin has strong antioxidant capacity, which can effectively inhibit free radicals and reduce joint injury. American scientists conducted an eight-week experiment on tennis elbow patients. The grip strength of people who took astaxanthin continuously increased by 93%, while the original pain of people who did not take astaxanthin increased.
Relieve exercise fatigue:
When the body exercises, muscles release free radicals. If these free radicals are not treated by antioxidants in time, they will produce oxidative stress, leading to muscle soreness or muscle tissue damage.
Studies show that astaxanthin can be used as an antioxidant to inhibit the oxidative damage of free radicals to the body. Oral astaxanthin can also strengthen aerobic metabolism, increase muscle strength and endurance, quickly relieve exercise fatigue and relieve delayed muscle pain after strenuous exercise.
Fight against "three highs" and prevent cardiovascular diseases;
The latest cardiovascular clinical research in the United States shows that oral astaxanthin can prevent the oxidation of low-density cholesterol (LDL, bad cholesterol), reduce platelet deposition, improve blood flow rate and reduce the risk of arteriosclerosis.
The School of Medicine of Chiba University of Economics in Japan found that taking astaxanthin for non-obese people can reduce triglyceride levels and increase high-density cholesterol (HDL, good cholesterol). A new study in Japan also found that compared with people who took astaxanthin for 4 weeks, the blood flow of retinal capillaries in both eyes of users was significantly higher than that of non-users. Scientists at Seoul National University in South Korea have also found that astaxanthin can reduce low-density cholesterol in obese people.
Anti-aging, anti-ultraviolet radiation:
Ultraviolet radiation is an important cause of epidermal photoaging and skin cancer. Studies have shown that astaxanthin has a special effect on transglutaminase, which can consume putrescine when the skin is exposed to light. Oral astaxanthin has a stronger inhibitory effect on putrescine accumulation than oral vitamin A, so its strong oxidation resistance makes it a potential photoprotective agent, which can effectively remove free radicals that cause skin aging, protect cell membrane and mitochondrial membrane from oxidative damage and prevent skin photoaging.
Prevention of diabetes:
Natural astaxanthin can prevent diabetes and prevent diabetic complications by preventing asymptomatic inflammation. It is found that diabetic patients are often accompanied by abnormal hyperglycemia and high oxidative stress, which are inevitably related to diabetic complications such as nephropathy. Astaxanthin can protect cells with high glucose content and regulate oxidative stress, inflammation and cell decline in patients with diabetic nephropathy. Astaxanthin can be used as an effective functional supplement against diabetes.
Method for obtaining astaxanthin
Expert: Many foods contain astaxanthin! Such as shellfish, fish, shrimps and crabs, algae, etc.
Algae: Astaxanthin is the most abundant, such as kelp, laver and Undaria pinnatifida.
Shrimp and crab: 1000 grams of shrimp shell contains 80- 100 mg of astaxanthin. The food containing astaxanthin in crayfish is the highest among all shrimps and crabs, and it can be ingested by eating soft-shelled crabs or shrimp skins.
Fish: 1000g contains about 10-40mg astaxanthin.
Shellfish:1000g contains about10mg of astaxanthin.
