Relationship Between Hydrate and MoisturizeĤ. Hydrating is necessary for people with dehydrated skin, while moisturizing is necessary for people with dry skin. Hydrating and moisturizing are two important skincare systems when you have dehydrated or dry skin. Now grab some moisturizer and keep reading for more links to skin stuff you might like.The main difference between hydrate and moisturize is that hydrating provides the skin with moisture while moisturizing helps the skin to retain moisture.Īlthough both hydrate and moisturize are similar words, in skincare, these two have slightly different meanings. Fortunately, a shower after the pool to rinse off the chlorine usually takes care of it. Swimming pools, at least hygienic ones, dry skin thanks to the chlorine. In addition to hand-washing, swimming can be a problem. When you do wash, use a gentle, nondetergent-based soap, and moisturize frequently." When you start washing your hands 30 to 50 times a day, that's not good. Obviously, if you've shaken hands with someone with the flu, wash your hands. To the teachers, nurses, doctors, dentists and other frequent hand-washers of the world, dermatology professor Aftergut says, "Don't wash your hands excessively. This life-giving liquid doesn't actually dehydrate you the substances in it do, such as soap. We're not done yet: Water can also be a problem. And in the sun (or snow), wear a UV-blocking sunscreen. Inside, if you use a heater, return moisture to the air with a humidifier or a pan of water in the room. If it's too warm for layers, moisturize exposed skin. The air can't burglarize skin that it doesn't touch, so when you're outside, shield yourself with a jacket, hat and gloves. If your skin is reddened by the rays, you've experienced enough. You don't need a high dose of rays to see the effect. Like dry air, ultraviolet rays from the sun shut off an enzyme that stocks the stratum corneum with natural moisturizing factors. If the UV index is high, your skin is under further attack. Cold makes us switch on the heater, and the heater dehydrates our skin by dehydrating the air. Let's say we're in a city where it's dry and cold. When the humidity drops below 10 percent, the enzymes that make some of our natural moisturizing factors don't work as well. Then, water escapes from our skin more easily because the flaking shortens the distance to escape. įor instance, at low humidity, enzymes that cut connections among cells on the skin's surface, allowing such mild skin-shedding that we can't see it, start chopping deeper in our skin, and our skin flakes. But be careful: Some creams promise to replace waning moisturizing factors that the skin can't actually absorb. We also can use creams that replace natural moisturizing factors that our genes have slacked off in making. For instance, instead of lathering soaps, which yank fats out of our skin, we can switch to mild soaps that don't lather. But we can stop disabling the equipment we have. We can't stop our genes from making less moisture-trapping equipment in our skin as we age. Kent Aftergut, a clinical assistant professor of dermatology at the University of Texas, Southwestern at Dallas. By age 50 to 70, spots of dry skin show up on even the healthiest of hands, says Dr. Almost every layer of the epidermis gets more barren: We make less natural moisturizing factors, less ceramides and less hyaluronic acid. After our teenage years, we make less of the molecules that trap water in our skin. Read on to learn more about some biological causes of dry skin.Īs we age, our skin gets worse at retaining moisture. And for people with skin conditions, drying and cracking can open the already weak barrier, admitting skin bacteria like Staphylococcus species, for a gnarly infection. When our skin dries, these enzymes falter, and the skin has trouble keeping water in and infections out. Housekeeping enzymes in our skin need water to work. Our dry skin has a good reason to complain. Dry skin grays with dead cells and forms rashes and, just in case we didn't notice, itches and stings. If our skin is built to hang on to moisture, then why does it dry out? Our genes, our age, evaporation and osmotic pressure all make a difference. Cells in this layer sport hyaluronic acid, a sugar that binds to water, on their surfaces. Last but not least is the stratum spinosum at the bottom. Channels let water from deeper layers into this layer, but not out. Its top half is almost watertight, the cells being sewn together by a type of protein thread. Next, we're on to the stratum granulosum. The layers also give water too far to travel to reach the surface of the skin. When water tries to evaporate from lower layers of the skin, it gets trapped in spaces between the fat molecules and can't rise any higher. Ceramides, cholesterol and fatty acids are some of the fats you'll find here, arranged into layers of jelly and liquid. A layer of fat sits below the stratum corneum.
