Depth look at beauty, strengthen the autumn and winter skin replenishment scientific papers

As temperatures cool in the process of change is exactly the dry skin from the moist process.

As the moisture in the air temperature decrease due to the steady decline in the external skin is difficult to absorb more moisture, so the problem appears dry. Therefore, I advocate "enhanced moisturizing" the science of skin care concept. Indeed, the choice of what kind of life, beauty care, procedures, usually we are most concerned about is their own after moisturizing skin care skin feeling and that can keep a sense of how long? Brand is a product of concern to several cycles of use, whether the effects of play was recognized by the customer. Therefore, to solve the core issue is to promote "enhanced replenishment of Rejuvenation," the beauty care program! Our depth of knowledge from the scientific point of skin skin, to moisturize the Secret to strengthen the process of the skin: Sense of normal human skin moist, tender feeling, playing sexy first with the water content is closely related to human skin. Water content in the stratum corneum is about 10 to 20%, while the stratum corneum water content of these cells were more than 80%. When the moisture content of less than 10% of the stratum corneum, the stratum corneum will be brittle and easy split, skin appearance is rough, but a good sense of loss of skin. Despite the daily human skin has a water evaporation, but because there are natural in the skin moisturizing system exists, the normal skin has the ability to self-regulation to maintain a certain water content. Highlights: skin tissue in the dermis and epidermis to water absorption and storage is completely different.

UGG Classic Cardy 5819 Black1, people in the water, the body metabolic processes tend to make the most of the water through sweat and urine excretion of the two channels to which a small number of water permeation through the cell body, first to reach the dermal layer of the cell, and then with the metabolism process, the cell structure into necrotic epidermis toward the dermal extracellular fluid within the cell is eliminated, and gradually separated water and a variety of biochemical substances move from the epidermal cells outside the gap to complete excretion. Therefore, the total water content of the skin, the dermal cells of memory more than 80% of the water, in which the papillary layer in shallow than deep plexiform layer to much. The water, maintain water filling the interior of the shells will be hot to the skin provides a basis for assurance. , the stratum corneum is no life activity of keratinocytes formed. Keratinocytes width of 30 microns, 0.8 microns thick, hexagonal, they are closely linked, cascading cross, about 10-20 layers of the stratum corneum, 10-15 microns thick. Keratinocyte cell membrane, cell contents and cell matrix with water to determine the softness of the skin. Keratinocyte gap between about 0.02-0.2 micron, which is full of layered structure of the lipids, natural moisturizing factor and in the hydration state of water. The skin surface cells to obtain only one channel of water that is adjacent with the inner membrane and its cell membrane, through the dialysis membrane and the membrane transfer and implementation. In fact, the outer side of the skin surface cells and inner cells can not be directly exposed, and thus little opportunity to absorb moisture, then easily lead to the outer side of desertification (local water) state caused skin problems. 


UGG Classic Cardy 5819 BlueNatural moisturizing factor (referred to as the NMF) is present in the stratum corneum water in combination with some of the general term for low molecular weight substances, including amino acids, pyrrolidone carboxylic acid, lactate, urea, ammonium, uric acid, glucosamine, citrate, sodium , potassium, calcium, magnesium, phosphate, chloride, sugars, organic acids, peptides and other unknown substances. NMF matrix keratinocytes account for 10% to attract water molecules through the osmotic pressure, and the NMF with water is relatively fixed part of the stratum corneum, the content of that part of the larger changes in the stratum corneum water permeability and selective lipid barrier, whereas the permeability and skin cells and lipids and the integrity of lamellar structure and characteristics of related. Normal stratum corneum hydration by some to maintain a certain humidity, the stratum corneum and the external environment from the body to get water, the latter by the ambient relative humidity, if the relative humidity dropped, the stratum corneum water will evaporate, produced until a new balance in the skin in a low humidity environment must rely on the lower epidermis and dermis to provide water to add. 3, after the composition of the dermal and epidermal structure of introduction, we can clearly see: Water storage and NMF is closely related to the change: ----------------- ------------------------ Epidermal basal layer stratum corneum Cells ------------- ------------- keratinocyte cells outside the main gap membrane emulsification NMF -----------& nbspNMF loss is eliminated ----------------------& nbspNMF Body of water sources ---- ------- vivo and in vitro in vitro water source water sources

  

UGG Classic Cardy 5819 GreyShould also be recognized that in the epidermis to prevent water loss, mainly dependent on oil barrier function. Lipid changes in the skin; Granular layer below the stratum corneum ------ ------- ---- diagonalization process of surface Tissue cells gradually expelled --- - --- between keratinocytes in the epidermis covering the outer Skin care moisturizing the skin after continuous long-term effects and whether it depends on how much water has added? Moisturizing factor (NMF), absorbing many? The formation of the lipid barrier of the outer epidermis status? Therefore, understanding the way skin absorption is particularly important! ! !
