Aging is a natural phenomenon in the process of life. Although it is unstoppable, people can slow down the pace of aging through some means. Anti-aging cosmetics are such a kind of cosmetics for the purpose of delaying skin aging. This kind of cosmetics can achieve the purpose of delaying skin aging through the following types of functional raw materials.
1 Raw materials with functions of moisturizing and repairing skin
Such raw materials can keep the water content in the stratum corneum of the skin in an appropriate range and reduce the formation of wrinkles. Such as glycerin, allantoin, sodium pyrrolidone carboxylate, lactic acid and sodium lactate, ceramide and hyaluronate acid.
2 Raw materials that promote cell proliferation and metabolism
Such raw materials can promote cell division and proliferation, promote cell metabolism, accelerate the renewal speed 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), vitamin A acid, marine peptides, sheep embryonic acid, β-glucan, uridine and kappa elastin, etc.
3 Antioxidant raw materials
Aging is closely related to many oxidation reactions, and anti-oxidation can resist aging, so such raw materials have an irreplaceable effect in anti-aging cosmetics. The commonly used antioxidant materials mainly include: ①Vitamins, such as vitamin E, vitamin C, etc.; ②Biological enzymes, such as superoxide dismutase (SOD), coenzyme Q10, etc.; ③flavonoids, such as proanthocyanidins, tea polyphenols , Baicalin, etc.; ④ Proteins, such as metallothionein, papaya thioprotein and sericin.
4 Sunscreen raw materials
Long-term ultraviolet radiation will accelerate the aging process of the skin and make the skin age prematurely. Therefore, sunscreen raw materials are an indispensable category of anti-skin aging products, such as DHHB (Diethylamino Hydroxybenzoyl Hexyl Benzoate), Bemotrizinol (BEMT, Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine), carbomer (carbomer 940, carbomer 980)etc..
5 Natural extracts with complex effects
Many natural animal and plant extracts have good anti-aging effects, and are usually multi-angle compound effects. They have the advantages of mild action, long-lasting stability, wide application range, and high safety. They are becoming more and more popular among consumers. Recognized. In particular, some Chinese medicine extracts have been widely used in anti-aging products, such as ginseng, astragalus, gynostemma pentaphyllum, velvet antler, ganoderma, seabuckthorn, tuckahoe, angelica, pearl, ginkgo and evening primrose.
6 Trace elements
The anti-aging effect of trace elements has become a research hotspot in aging biology in recent years. A large number of studies have proved that the main trace elements closely related to anti-aging are zinc, copper, manganese and selenium.
