Ellagic acid,The main role of Pomegranate ellagic acid in cosmetics and skin care products is antioxidant and astringent. It has the properties of phenol and carboxylic acid. Due to its special structure, it has strong anti-oxidation, anti-mutation and anti-free radical effects, which can improve The endothelium relaxes dependently, shrinks pores, and makes the skin delicate and smooth.
Pomegranate ellagic acid is one of the natural and effective whitening ingredients recognized by the medical community. It is a kind of polyphenol molecule, which is widely found in many kinds of plants and fruits in nature. Used to whiten skin, inhibit tyrosinase activity, block melanin production, and have whitening and spot-lightening effects. The current whitening products on the cosmetics market are mostly based on tyrosinase inhibitors, such as kojic acid and arbutin. Ellagic acid extracted from natural plants can be added to cosmetics or mixed with other ingredients to be safe and effective as an active whitening ingredient.
Many people know that free radicals are a substance harmful to human cells, which can cause oxidation and pathological changes in human cells. Normally the human body absorbs a certain amount of ellagic acid, which can eliminate free radicals in the body and improve the body’s resistance. Oxidation ability can reduce the damage of free radicals to human cells, maintain human health and slow down the speed of human aging.
Some lipids contained in the human body will increase the burden on the human body after being oxidized, and some chronic diseases will occur. After the human body absorbs abundant ellagic acid, it can prevent the oxidation of these lipids and prevent the production of oxidized lipids in the body. It can prevent them from damaging human cells. Regular consumption of foods with ellagic acid can improve the activity of human tissue cells and prevent the body from becoming pathological.
After being absorbed by the human body, ellagic acid can also remove the melanin in the body, accelerate the decomposition of melanin, and prevent the accumulation of melanin on the skin surface. It can also prevent melanin production from the root, and can prevent the appearance of stains on the surface of human skin. To a certain degree of whitening effect, this substance is widely used in the production of cosmetics and medicines.
At present, people's concept of skin whitening has undergone a fundamental change, from physical whitening to covert whitening to biological whitening by means of melanin reduction.The formation process of melanin is based on tyrosine, which is converted into dopa and dopaquinone under the action of tyrosinase, and finally melanin is formed. Ellagic acid has a high affinity for copper in the active site of tyrosinase and can inhibit tyrosinase activity. In a comparative test of topical application of ellagic acid on the epidermis of brown guinea pigs, it was found that ellagic acid can effectively inhibit skin pigmentation caused by ultraviolet rays.
