What are the functional raw materials of anti-aging cosmetics?
1. Raw materials with moisturizing and repairing skin barrier function Such materials keep the water content in the stratum corneum of the skin within the appropriate range, reducing the formation of wrinkles. Such as glycerin, allantoin, sodium pyrrolidone carboxylate, lactic acid and sodium lactate, ceramide and hyaluronic acid, etc. 2, promote cell proliferation and metabolic capacity of raw materials This kind of raw materials can promote cell division and proliferation, promote cell metabolism, accelerate the renewal rate of epidermal cells, and delay skin aging. Such as cell growth factors (including epidermal growth factor, fibroblast growth factor, keratinocyte growth factor, etc.), deoxyribonucleic acid (DNA), tretinoate, fruit acid, Marine peptide, sheep embryin, beta-glucan, uridine and kaba elastin, etc. 3. Antioxidant raw materials Aging is closely related to many oxidation reactions, and antioxidant can be anti-aging, so this kind of raw material has an irreplaceable role in anti-aging cosmetics. Commonly used antioxidant materials mainly include: Vitamins, such as vitamin E, vitamin C, etc.; Biological enzymes, such as superoxide dismutase (SOD), coenzyme Q10, etc.; Flavonoids, such as proanthocyanidins, tea Polyphenols, baicalin, etc.; Proteins, such as metallothionein, papaya thionein and sericin. 4. Sunscreen materials Long-term ultraviolet radiation will accelerate the aging process of the skin and make the skin age in advance, so the sunscreen raw materials are an essential class of anti-aging products. 5. Natural extracts with compound effects Many natural animal and plant extracts have good anti-aging effects, and usually are multi-angle compound effects, with mild and durable stability, wide range of application, high safety advantages, more and more favored and recognized by consumers. Especially some Chinese herbal extracts have been widely used in anti-aging products, such as ginseng, Astragalus, gynostemma pentaphyllum, antler antler, ganoderma lucidum, sea buckthorn, poria, angelica, pearl, ginkgo biloba and evening primrose. 6. Trace elements In recent years, the anti-aging effects of trace elements have become a hot research topic in aging biology. A large number of studies have proved that the main trace elements closely related to anti-aging are zinc, copper, manganese and selenium
