If your skin lacks radiance and feels “tight” it is likely that it is dehydrated. The aspect of fine lines due to loss of elasticity and flexibleness are other key signs of dehydrated skin. Moisture evaporates readily through the skin, and if we don’t stop this occurrence our skin looses it is capacity to protect versus the outside environs leading to even more moisture loss and in the long term, actual skin harm due to poor cellular integrity. Wind, sun and pollution as well as internal components such as diet, nutrient levels and hereditary all play a role in the determining the health of our skin as an effective barrier. The very outer layer of our epidermis (top skin layer) is the real protective layer of the skin. It is made up of flattened dead keratinocytes. These dead skin cells are regularly shed and substituted by deeper skin layers moving up to the surface. The glue that keeps the keratinocytes together is formed by lipids such as fatty acids ceramides and cholesterol. This layer forms a waterproof barrier that reduces “Trans Epidermal Water Loss” or TEWL, ensuring adequate moisture content for the skin. It is this barrier that protects versus chemicals, irritants and micro-organisms. A deficiency in these epidermal lipids causes the water retention powers of the epidermis to be significantly reduced. Moisture evaporation and skin dehydration in general follow. One division of the skin’s waterproof moisture barrier is more or less acidic and as such is recognise as the acid mantle. The acidity of this layer is due to secretions from the sebaceous and sweat glands and it is function is once again shelter but in peculiar stopping the growth of bacteria and fungi. It also helps with sustaining the “glue” that keeps the outer layer skin cells bound together. If acid pH of the skin is disrupted it becomes more alkaline and starts to lose it is protective properties. It is the remainder of sebum (skin oil) and perspiration that keeps the skin healthy. Skin dehydration occurs when the water and oils that form part of the protective layer are out of balance. This may take place for a number of reasons: 1. Evaporation of moisture through the skin. Factors that promote moisture evaporation include arid air (ie lack of humidity or airconditioning), wind, prolonged water exposure (swimming in pools or long showers). 2. Damage to the waterproof barrier or disruption of the acid mantle leaving the skin open to issues such as dehydration, roughness, infection, redness and irritation. Synthetic foaming agents such as sodium laurel sulphate are a substantial cause of acid mantle disruption. 3. Low water and healthful fat intake – adequate water intake is required to maintain cellular fluid. Essential fatty acids from good fats support maintain the fatty membrane surrounding the cell, keeping in moisture and nutrition. 4. Ageing. As we age, there is a reduction in the water keeping capacity of the skin as well as the production of natural oils. The introductory thing to do to combat skin dehydration is to remove any constituents that directly bestow to moisture loss or skin damage. Avoid long, hot showers, open the windows rather of relying on air-conditioning and stop using merchandise that integrate sodium laurel sulphate. Repairing these elements will slow down water loss. Dietary components will be addressed underneath but surely assure you are getting sufficient water each day which will aid increase water content. The next step is to repair the waterproof barrier and restore the skin’s capacity to attract and retain water. Ideally any skin care product employed will have a number of roles which include delivering nutrition which helps with repair, maintenance of the acid mantle and moisture barrier and a softening effect achieved by attracting water from the external environment. To achieve this, the ingredients ought to be capable to be absorbed decently by the skin. Water based ingredients may have a temporary plumping effect on the surface of the skin but this effect will not last as the ingredients haven’t been absorbed into the deeper layers of the skin. Lipids and oil soluble ingredients are more readily absorbed by the skin as are ingredients that have a littler particle size. Most cosmetic merchandise on the market don’t actually support the skin repair harm to the barrier or acid mantle. They act as emollients, reducing water loss from the skin by covering it with a protective layer. Effectively they keep water in the skin. Common emollient ingredients include butters, waxes and oils as well as productions such as petroleum and lanolin. While emollients are helping to reduce the problem, they aren’t actually remedying the underlying cause. The other issue with a heap of emollient ingredients is that they may actually cause more problems. Petroleum productions such as solid homogeneous inorgani substance oil sit on the surface of the skin, stopping the skin from breathing and have the potential to block pores. By contrast natural waxes and oils concede the skin to breath. Some of the heavier waxes or butters may still block pores nonetheless natural carrier and necessary oils are improbable to have this effect. When it comes to ingredients that achieve this end, our natural pantry is rich in ingredients that may help restore skin hydration rather than just masking the problem. Many natural carrier oils such as Rosehip, Sweet Almond, Tamanu, Marula, Jojoba and Evening Primrose Oil are readily absorbed by the skin. They have the capacity to nourish the skin, provide an effective barrier to water loss and reduce TEWL. Oils such as Rosehip also integrate necessary fatty acids (EFAs) that promote the repair of the cellular membrane, permitting skin cells to retain more water. Ironically if the skin cells are deficient in EFAs, it may cause the sebaceous glands to become overactive, formulating more oil. With an EFA deficiency, the skin will often be oily through the T-zone and arid throughout the cheeks. As long as the suitable natural carrier oils are used, they may have a balancing effect, reducing both oily and arid skin conditions. Ideal selections for skin that is both oily and arid include Rosehip and Sweet Almond. Many carrier oils such Marula, Rosehip and Boabab likewise integrate necessary skin vitamins such as A, E and C that publicize healthful cellular function. As antioxidants, the vitamins likewise help slow skin ageing. What you do on the “inside” also has an affect in skin hydration. Reducing constituents that have a diuretic effect such as alcohol and coffee will increase cellular hydration. The other key issue is ensuring adequate good fats in the diet. Good fats such as necessary fatty acids (EFA’s) ascertain the cell membrane remains flexible. This allows the cell to excrete toxins and cellular waste productions and hold onto nutrients and water. EFAs also support to keep skin flexible and hydrated and furthering skin healing. Deep Sea fish are amongst the best source of EFAs including tuna, salmon, anchovies and sardines. Other good roots of EFA’s include avocado, nuts & seeds, flaxoil and Evening Primrose Oil. |

Great!
