Skin aging and antiaging cosmetics

Thereby it causes the disease susceptibility or death. It is a natural regulation involving in the body tissues and organs. The skin is an important organ, covering the surface of the body consists of the epidermis, dermis, subcutaneous tissue and skin accessory organs (including the sweat glands, sebaceous glands, hair and nails). Skin is a natural barrier between the external environment and the body. However, the skin's protective effect is limited. When outside influences reach to a certain degree, skin aging has become a necessity.

The main manifestations of skin aging are a natural aging and light aging in two forms. Human skin from 20 - 25 years old to enter the natural aging on the one hand, increase with age, the amount of sebum secretion to reduce the keratinocytes (fat) quality is also reduced. And thus reduced water retention capacity of the skin moisture barrier function of the gradual decline of percutaneous water loss TEWL values rise, began to dry skin problems; the other hand, the epidermal cells reduced ability to epidermal recovery rate slows down, the horny tretinoin functional decline and thinning of the stratum corneum, the epidermis atrophy produce fine wrinkles. Total glial cells in the dermis to reduce part of the glial cells because of lipid peroxidation, increase in the degree of crosslinking, resulting in insoluble collagen, leading to decreased elasticity, the basic components of the dermal connective tissue hyaluronic acid also increased with age and reduce the , resulting in dermal moisture reduced, resulting in deeper wrinkles.

Placenta is the essence of an active embryonic cells directly extracted and refined from the ewe placenta three months of pregnancy. Placenta contains EGF DNA, SOD and was named for the vitamin activity of X factor and mucopolysaccharides, lipoproteins, enzymes, vitamins, hormones, minoxidil, lecithin, thymosin and minerals, a variety of long-term studies of medical and beauty industry, nutrients, these active substances can penetrate the skin and deep tissues, stimulating cell division and activation of human tissue to promote the discharge of the decomposition of the aging cells, thus delaying the skin aging.

Collagen constitute the animal and muscle protein, it is synthesized by fibroblasts. Contains soluble collagen rich in proline, glycine, glutamic acid, alanine, threonine, methionine, and other 15 kinds of amino acid nutrients will be applied to cosmetics, easily absorbed through the skin, to promote the vitality of epidermal cells , increase nutrition, effective elimination of the skin and fine wrinkles.

Glutathione peroxides are glutamic acid, glycine and cysteine-based hydrogen peroxide reductase, mainly present in the mitochondrial (such as human, animal placenta, red blood cells). GTP can be in the hydrogen peroxide generated by catalytic decomposition of water and oxygen, unsaturated lipid membrane to protect the skin, dermatitis caused by treatable lipid peroxides, reduce pigmentation, anti-aging effects.

The central role of vitamin E that as the body’s antioxidants, it is a free radical remover to prevent the formation of lipid peroxidation, protect the SOD and reduce the rates of conversion from soluble collagen to insoluble collagen. Thereby it maintains skin elasticity and reduces wrinkles.Source:http://www.cosprm.com
