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 cosmetics aimed at delaying skin aging. This kind of cosmetics can achieve the purpose that postpones skin consenescence through following a few kinds of functional raw materials.
(1) Raw materials with functions of moisturizing and repairing skin barrier
This kind of raw material can keep the moisture content in cuticle of the skin in appropriate limits, reduce the formation of wrinkle. Such as glycerin, allantoin, sodium pyrrolidone carboxylate, lactic acid and sodium lactate, ceramide and hyaluronic acid, etc.
(2) Raw materials to promote cell proliferation and metabolism
Such raw materials can promote cell division and proliferation, promote cell metabolism, accelerate the regeneration rate of epidermal cells, and delay skin aging. Such as cell growth factor (including epidermal growth factor, fibroblast growth factor, keratinocyte growth factor, etc.), DEoxyribonucleic acid (DNA), retinoic acid, fruit acid, Marine peptide, sheep embryo element, -glucan, uridine and caba elastin, etc.
(3) Antioxidant raw materials
Aging is closely related to many oxidation reactions, and anti-oxidation can fight against aging, so this kind of raw materials have an irreplaceable role in anti-aging cosmetics. Common antioxidant raw materials include:
Vitamins, such as vitamin E, vitamin C, etc.; Biological enzymes, such as superoxide dismutase (SOD), coenzyme Q10; Flavonoids, such as procyanidins, tea polyphenols, baicalin, etc.; Proteins, such as metallothionein, papaya thionein and sericin, etc.
(4) Sunscreen raw materials
Long-term ULTRAVIOLET radiation will accelerate the aging process of the skin, making the skin aging ahead of time, so sunscreen raw materials is an essential type of anti-aging skin products.
(5) Natural extracts with complex effects
Many natural animal and plant extracts have a good anti-aging effect, and are usually multi-angle compound effect, with mild and stable effect, wide range of application, high safety advantages, more and more consumers are favored and recognized. In particular, some herbal extracts have been widely used in anti-aging products, such as ginseng, astragalus membranaceus, gynostander, Deer antler, ganoderma lucidum, sea-buckthorn, poria cotta, Angelica sinensis, pearl, ginkgo biloba and evening primrose.
(6) Trace elements
In recent years, the anti-aging effect of trace elements has become a research hotspot in the biology of aging. A large number of studies have proved that the trace elements closely related to anti-aging mainly include zinc, copper, manganese and selenium.
