Skin hydration, several mechanismsProper hydration of the skin remains a major issue these days for all men and women continually subjected to the stresses of life. The more hydrated the skin, the better the nutrients can circulate in the blood to supply our cells. Except that with the winter cold, the blood circulation concentrates on the vital organs to keep them at the right temperature of our body and thus ensure their survival. As a result, the skin, a peripheral organ, suffers. So how do you maintain both good hydration and good energy during this winter period to boost cellular metabolism? This sheds light on the hydration mechanisms essential to beautiful skin.NABILAFebruary 20221. PROPERLY MOISTURIZE AND ENERGIZE, ESSENTIAL BEAUTY GESTURES FOR BEAUTIFUL SKIN IN WINTER!Water is the main constituent of our body since it represents on average 70% of its total mass. This mass is 75% in infants and 65% in adults and can drop to 45% depending on morphology and age. The majority of this water, nearly 55%, is lodged in our cells, which also explains the gesture of pinching the skin by the dermatologist to assess its degree of dehydration. It is at all levels that you encounter water in the skin, which will be more or less protected from external aggressions depending on the quality of its barrier function. This function of the skin will be regulated at 3 levels via its ability to:WATER TRAPPINGensured by the presence of hygroscopic substances, such as NMF (Natural Moisturizing Factors), which will maintain the water inside the cells. Any alteration of the membrane of these cells leads to the escape of these hygroscopic substances, which are amino acids for almost half, and therefore the loss of this natural humification factor. I'hyaluronic acid is also a molecule in our skin that will trap water, but it is found in the dermis and not in the epidermis.OPTIMAL WATER DISTRIBUTION ensured by the water channels, the Aquaporins. These small membrane proteins are dedicated to transporting water and thus make it possible to regulate the movement of water between cells at different levels of the epidermis.LIMITATION OF WATER LOSSIndeed, the free water coming from the dermis, crosses the different layers and evaporates on the surface of the skin or combines with the hydrophilic phase of the hydrolipidic film. This permanent flow of water evaporation, called Transepidermal Water Loss (PIE), depends on the thickness and integrity of the stratum corneum, the nature and quantity of lipids cementing the cells or even the application oily topicals on the skin.Know that the more the stratum corneum is rich in water, the lower this PIE. Similarly, the more the skin is hydrated, the more it will be permeable to treatments and their active ingredients. Our stratum corneum is able to absorb up to 9 times its own weight.In addition, the level of hydration of the skin is an important factor in its protection against repeated exposure to various agents or potential irritants such as too frequent washing with aggressive products. More generally, skin hydration is an essential factor because it is likely to profoundly modify the properties of the skin.Another important factor in preserving water inside the epidermis concerns the quality and quantity of intercellular lipids which cement the cells together and therefore prevent water leakage. This lipid fatty cement is largely composed ofessential fatty acids which it is necessary to supply the skin with nutrition since the body almost does not synthesize them. These essential fatty acids are also a vector for skin penetration of cosmetic active ingredients.Cold diverts energy from the body to vital organs. Beyond hydration, beautiful skin will necessarily go through energizing treatments to boost communication and cellular exchanges that work in slow motion. THE " super foods which are none other than foods with an exceptional richness in nutrients and energizing treatment masks are of great help. Thanks to its high content of cold-extracted pure date pulp, our luminous mask “ Divine Sap is a real booster of all cellular metabolism and will dress your skin with remarkable radiance. Do not hesitate to boost your cellular metabolism by including superfoods such as date, the chlorelle, spirulina, goji berries, cocoa to consume preferably in the morning.2. DESERT PLANTS, A TREASURE OF ACTIVE INGREDIENTS TO MOISTURIZE THE SKIN As you probably know, we are fans of desert plants ! Nature does things well... and if for millennia plants like the prickly pear, the jojoba, l’Aloe vera, the desert date palm or even the date palm knew how to make the desert, an arid environment exposed non-stop to solar radiation and drought, their favorite place, it is good that these plants enjoy a prodigious capacity for defense and water retention! These plants have thus developed a natural strategy to collect the quantity of water necessary for their growth: trap more water, optimize its distribution and limit its losses. Everyone has their own secret for providing maximum hydration. Some contain an impressive richness in essential fatty acids or beta-sitosterols such as virgin prickly pear seed oil - present in the redensifying serum and in the intensive cream - or the virgin oil of the desert date palm present in the nourishing balm and thecleansing oil. And it is the virgin oil that we use of course since only thevirgin oil remains provided with its essential fatty acids unlike refined oil. Other plants contain a high content of polysaccharides or even amino acids such as dates or Aloe vera, which stimulate cell metabolism and coat the skin with a tensor and moisturizing film.As you have understood, hydration of the skin is therefore essential to its appearance, its protection, its suppleness, its softness, its complexion and also its ability to defend against environmental factors.
