Because most moisturizers are oil-in-water emulsions, they are creams and lotions by definition. When you look at the ingredient list, you’ll notice that water is frequently listed first. When you apply the moisturizer, some of the water evaporates, but some soaks in. you can buy from xulnaz lotion for dry skin. While the stratum corneum absorbs water efficiently, it does not bind it well, necessitating the use of an oily material to keep it in.Applying an oily material to the skin without also rehydrating it with water — whether from the moisturizer or another external source such as a bath — is ineffective: you’ll end up with greasy skin that is still dry and cracked. In fact, the best technique to soften skin is to soak it in water for a long time and then coat it with Vaseline. However, because this is time-consuming and untidy, unless your skin is really dry, using a water-based moisturizer is far easier and more practical.
Petrolatum and other greasy ingredients in moisturizers are known as occlusives because they prevent water from evaporating. Despite the numerous differences in moisturizers, petrolatum is a standard, often appearing third or fourth on the ingredient list. Occlusives can be made of a variety of fatty or waxy substances. Cetyl alcohol (a fatty alcohol), lanolin, lecithin, mineral oil, paraffin, and stearic acid are among the most regularly utilized. Occlusives such as dimethicone and cyclomethicone are silicones. When a product says it’s oil-free, it usually indicates it’s devoid of mineral or vegetable oil and instead relies on dimethicone as an occlusive. Although the Aveeno products advertise their “natural” oatmeal content, dimethicone is the only active ingredient indicated in some versions.
Humectants, in theory, draw water into the stratum corneum from both the air and deeper layers of the skin. When the humidity is low, however, there is so little water in the air that practically all of the water must come from within. Glycerin, honey, panthenol (or vitamin B5, an example of a vitamin utilized for its physical rather than nutritional properties), sorbitol (which we are used to seeing as an artificial sweetener), and urea are some of the most often used humectants. By drawing water into a damaged, arid stratum corneum that doesn’t hold moisture, humectants have the potential to make skin even drier. As a result, occlusive substances are nearly often employed with humectants to trap the moisture that the humectants draw into the stratum corneum. you can buy from xulnaz lotion for dry skin.
Emollients. Emollients are used in moisturizers to make the skin feel smooth rather than moisturized. Many occlusive substances — dimethicone is an excellent example — and humectants can also be used as emollients. We tend to think of alcohols as drying — and out of place in moisturizers — because of rubbing alcohol (isopropyl alcohol). However, some alcohols (such as octyldodecanol) are good emollients.
Topical retinoic acid, a kind of vitamin A, stimulates the formation of collagen in the skin, reducing fine lines and wrinkles. It is the major ingredient of prescription antiwrinkle creams. However, retinyl palmitate, which has the advantage of being a very stable molecule but isn’t nearly as biologically active as retinoic acid, is utilized in some moisturizers. In the levels present in moisturizers, retinyl palmitate is unlikely to have much, if any, influence on collagen and wrinkles. It’s possible that retinyl palmitate has a humectant effect.
Vitamin C, also known as ascorbic acid, and vitamin E, sometimes known as tocopheryl acetate, are antioxidants that are added to foods. Some effects of topical vitamin C have been seen in studies, but only at high dosages. Because light and oxygen inactivate vitamin C, there are concerns regarding its use de moisturizers. Tocopheryl acetate, a form of vitamin E, is physiologically inactive and is most likely used as a preservative.
Menthol is commonly used in moisturizers marketed as itch relievers, such as Sarna. Although menthol does not address the underlying issue, the typical cooling sensation appears to alleviate itching.
The skin on the back of the heel can become particularly thick, leathery, and dry. Remove the outer layers of skin with a pumice stone or a callus file, then soften it with a moisturizer like AmLactin. AmLactin, an over-the-counter moisturizer, contains 12% lactic acid, a powerful humectant that can help dissolve adhesions, making heel skin more flexible and less prone to cracking. Lactic acid-based products can irritate the skin.
