Always remember that when the relative humidity is below 60%, skin starts to lose moisture. At this time, greater protection against moisture loss is needed. In case humidity is low, look for those moisturizers that contain petrolatum, mineral oil, or linoleic acid, ceramides, or even dimethicone, or glycerin.
In the case of high humidity, the skin can replenish itself. This is done by soaking up moisture from the air. Hence a lotion may be all that is required, in this case. Always, select moisturizers that feel pleasing to the skin. This will encourage you to use them. It is best to avoid moisturizers that contain fragrances, preservatives, as well as any other chemicals as they can irritate the skin.
In recent years, the structure and function of moisturizers has become surprisingly complex and sophisticated. In fact, many are equidistant between cosmetics as well as drugs. The moisturizers of today include agents that mimic natural ingredients, and are able to function as botanicals, which include vitamins, hydroxy acids, as well as retinoids. Other common ingredients of moisturizers are collagen, elastin, as well as DNA, ribonucleic acid (RNA), lecithin, as well as ceramides.
The moisturizers contain Humectants, which are substances that attract water when applied to the skin. Examples of humectants include glycerin, sorbitol, besides urea, alpha hydroxy acids (AHAs), as well as sugars.
Fragrances are used in moisturizers to mask the odor of formulation ingredients as well as to impart a pleasant and fresh aroma. Fragrance is added to nearly 65% of the moisturizers. Fragrances also happen to be the most common sensitizers. They are also the most likely irritating agents in individuals. Healthcare-associated infection due to using moisturizers could be reduced by improved hand hygiene practice. Regular application of moisturizer to healthy skin will offer a protective effect against exposure to irritants.
