What are the main ingredients of anti-aging cosmetics?

Victory peptide: protein whose amino acid number (the smallest unit in protein) is between 2 and 10. These peptides can be divided into two peptides (containing two amino acids), three peptides (containing three amino acids), polypeptides (multiple amino acids linked together) and so on. Different peptides have different functions: the second peptide can stimulate the production of collagen and protect the existing collagen; Tetrapeptide can promote the blood circulation of microvascular around eyes and effectively improve dark circles and bags under eyes; It can inhibit nerve conduction, relax expression lines and fade wrinkles, so it is called "botulinum toxin". Jiusheng peptide can block the transmission of MSH (melanotropin) and reduce the chance of melanin production. Growth factor: Growth factor is also a polypeptide, and its functions include promoting cells to produce collagen and stimulating angiogenesis. Studies have shown that growth factors can obviously dilute the wrinkles around the eyes and corners of the mouth. Phloretin: It is an extract of apple and a strong antioxidant. When phloretin is combined with vitamin C and ferulic acid, it can penetrate into the skin and hinder the formation of spots and wrinkles. It also plays a powerful role in preventing gene mutation that may lead to malignant skin cancer. Sirtui Su Huo Enzyme: This protease can repair cell damage, and it is the only component that has been proved to prolong cell life in the laboratory so far. In addition, Sirtui su huo enzyme can also enhance the production of collagen. α-lipoic acid: α-lipoic acid is one of the best anti-free radical components known at present. Its water-fat solubility can penetrate into the periphery and inside of cells, resist free radicals in any part of cells and resist the invasion of free radicals in an all-round way. A British study shows that among middle-aged women who use α -lipoic acid, 50% of them have significantly reduced wrinkles and smoother skin. Bosein: it is an effective component of ecological simulation and can promote the production of hyaluronic acid. Hyaluronic acid can absorb and fix water (up to 65,438+0,000 times its own weight), making the skin full and fine lines inconspicuous. Bosein can also strengthen the connection between cells (which will slow down with age), activate the production of collagen, and achieve the purpose of anti-wrinkle and firming. Nicotinamide: a derivative of vitamin B3, which can promote the high-speed operation of various enzymes and repair the DNA of cells. Although everyone's DNA has the ability to repair itself, nicotinamide can accelerate this repair process, repair light damage and fight cancer. In addition, nicotinamide can also slow down the aggregation of epidermal pigment cells. In other words, nicotinamide can prevent melanin from reaching the skin surface if melanin is precipitated on the skin due to sunlight, hormone imbalance or side effects of drugs. Acid A and its extension: Vitamin A enters the skin and is converted into acid A by a specific enzyme. It has many physiological functions by binding with six kinds of α -acid receptors on cells, among which the following functions have been proved when it is used for skin surface energy: anti-inflammatory reaction, regulating the growth and differentiation of epidermal cells, promoting the production of collagen, improving sebaceous gland function, reversing photoaging, inhibiting melanin production and promoting dermal thickening.
