This extract in skin care products can not only soften the skin, but also delay aging
"Alpine azalea" generally grows on high mountains. It first originated in the European Alps and Pyrenees. Now it is also distributed in Emei, Daxing'an Mountains, Changbai Mountains and other places in China. Alpine Rhododendron is a kind of medicinal plant, which was first used to treat cough, phlegm and asthma. However, in recent years, people have deepened their understanding of it. People have found that it has the effects of soothing, anti-inflammatory, anti-oxidation and skin rejuvenation. Therefore, some skin care products have begun to add Alpine Rhododendron extract.
Recently, scientists have carefully identified and studied the components of Alpine Rhododendron extract, identified 14 main components, and found that this small plant contains many secrets against aging, most of which are flavonoids, including quercetin, dihydroquercetin, catechin, etc. The study was published in cosmotics.
The biggest feature of flavonoids is its excellent antioxidant ability, which can effectively remove free radicals from cells and prevent cell aging. Quercetin, dihydroquercetin and catechin have been mentioned.
Quercetin is a natural inhibitor of CD38, which consumes nad+. Quercetin can delay aging by increasing nad+ levels. In addition, quercetin is also a light protective substance, which can effectively delay the aging of skin fibroblasts and play the effect of skin rejuvenation.
Dihydroquercetin is the reduced form of quercetin. Its effect is similar to that of quercetin. It can remove cell free radicals, play an antioxidant role, and also have anti-virus, antibacterial, anti-inflammatory and other effects.
It must be known that the most famous catechin is EGCG, which is very high in green tea, reaching more than 15%. It is an important substance for green tea to exert its benefits. Its antioxidant capacity is not inferior to the first two, 40~100 times that of vitamin C. In addition to anti-oxidation, it can also resist tumor, anti-inflammatory and protect heart and brain organs.
It is these flavonoids that endow Alpine Rhododendron extract with anti-oxidation, anti-aging, skin rejuvenation and other characteristics. The flavonoid family is very large. In addition to the above representative substances, time school has also reported other substances, such as curcumin in curry and urushiol in strawberry.
