It is like a one-way street that cannot be driven backwards, but we always want to delay the time to the end through some special means. Especially for women, the loss of collagen starts at the age of 25, although it is unstoppable
But people can slow down the pace of aging through some means.
Anti-aging cosmetics are such a type of cosmetics for the purpose of delaying skin aging.
Anyone who wants to delay skin aging all could use anti-aging natural ingredients.
When the water content of the stratum corneum of our skin is between 10% and 20%, the barrier function of the stratum corneum is good. Such raw materials as allantoin, lactic acid and sodium lactate, ceramide and hyaluronic acid are able to keep the water content in the stratum corneum of the skin within an appropriate range, prevent the skin from drying out and reduce the formation of wrinkles.
Cell growth factors added in skin care products (including epidermal growth factor, fibroblast growth factor, keratinocyte growth factor, etc.), deoxyribonucleic acid (DNA), fruit acid, retinoic acid esters, marine peptides, sheep embryonic acid, β-glucan, uridine and kappa elastin and other substances can promote cell division and proliferation, accelerate the renewal speed of skin epidermal cells, promote cell metabolism, and dipeptide diaminobutyroyl delay skin aging.
Almost every anti-aging cosmetics contains anti-oxidant raw materials, because anti-oxidation can prevent aging. The antioxidant raw materials to taste include vitamins, such as VE, VC; biological enzymes, such as coenzyme Q10, superoxide dismutase (SOD); flavonoids, such as proanthocyanidins, baicalin, tea polyphenols; proteins, such as Metallothionein, Papaya Thioprotein, Sericin.
Ultraviolet radiation will accelerate the aging of the skin, so sunscreen raw materials are also an indispensable type of anti-aging products. Common sunscreen materials can be divided into physical UV shielding agents and chemical UV absorbers. Such as titanium dioxide, zinc oxide, iron oxide, etc., these substances do not absorb ultraviolet rays, but can reflect and scatter ultraviolet rays, which can play a physical shielding effect on the skin. Chemical UV absorbers refer to organic compounds that can absorb and block harmful UV rays, such as anthranilates and dibenzoylmethane compounds, salicylate and so on.
Many natural animal and plant extracts have good anti-aging effects, and have the advantages of wide application range, high safety, mild and long-lasting action. In particular, some traditional Chinese medicine extracts have been widely used in anti-aging products, such as ginseng, astragalus, pearl, ginkgo, velvet, sea buckthorn, ganoderma, angelica, evening primrose, etc.
In recent years, the anti-aging effect of trace elements has also become a research hotspot in aging biology. A large number of studies have confirmed that the trace elements closely related to anti-aging are mainly copper, zinc, manganese, and selenium.
