Applying a moisturizer after every cleansing will immediately replenish the skin with structural lipids, smooth the rough, dry surface cells, and seal the barrier of the stratum corneum. A good moisturizer contains a mix of water-attracting and water-holding ingredients. Keep in mind, though, that as with every other product, it the total formulation that affects how the moisturizer feels on your skin as well as it’s hydrating potential. For example, two moisturizers can contain similar ingredients yet one will be more occlusive than the other, making it better for dry skin that needs that kind of invisible, nongreasy, water-holding shield. One moisturizer may work better under a foundation. And some women prefer a tinted moisturizer with sunscreen when they’re not wearing foundation. Men may prefer a moisturizer with more soothing ingredients to use after shaving.
Although most moisturizers are meant to be slightly occlusive, many of those on the market today don’t make the skin feel greasy. In the past, petrolatum or mineral oil was often used in a moisturizer because of its occlusive properties. With the new technology available to cosmetic chemists, though, these sticky products have been replaced with lightweight ones that are even more effective. They often contain ceramides that seem to dissolve right into your skin,
In the past most moisturizers were available in either a water-in-oil formulation or an oil-in-water one. People with dry skin were encouraged to use the water-in-oil products that were more occlusive; and people who produced too much sebum or structural lipids were advised to use oil-in-water products. These distinctions are now outdated, as new ingredients and manufacturing processes have improved the formulations.
New delivery systems are also now incorporated into many moisturizers. The liposome, for instance, involves a kind of encapsulation process that transports whatever agent is put within the liposome into the epidermis. In contrast, biovectors can be attached to ingredients to keep them at the top of the skin.
Typically women prefer creamier moisturizers, and men prefer lotions that don’t have thickening agents. But a lotion can be just as hydrating as a cream. One of the most popular moisturizing products in the Murad skincare line is neither a lotion nor a cream, but a viscous liquid. It’s a combination of only water-attracting natural moisture factors and water-holding lipids. It’s light and it’s absorbed immediately into the skin, moistening and smoothing the stratum corneum and leaving no trace on the skins surface.
I believe that everyone, even those people with oily skin, needs to use a moisturizer. The idea of a moisturizer is not to add structural lipids alone. Rather, a moisturizer serves several purposes: smoothing, hydrating, and restoring the barrier function of the stratum corneum.
