Natural mechanism for moisturization
On our skin surface, there are molecules that form a matrix to retain moisture. These mixtures of molecules are known as skin's natural moisturization factor. Some of these molecules include lactic acid, urea, etc. These molecules form an oily film on our skin to help preserve natural moisturization.
There are two types of cleansers, surfactant based or oil based. Surfactant type is the most common. The emollient based are for the removal of make up and oil-based paint etc. Both types of cleansers
can disturb the natural oily film that preserves the moisturization of our skin. How much damage the cleanser create is dependent on the formulation of the cleanser. Repetitive washing with cleansers can dry out your skin. One good example would be medical personnel who wash their hands too many times a day with harsh cleansers can leads to drying and cracking of the skin. For this same reason, washing your face more than twice daily and showering more than once a day are not recommended.
Skin moisturizers are designed to maintain the proper hydration on the surface of the skin. Although there are hundreds of different products available on the market, there are only two basic mechanisms in achieving moisturization.
The first way is to increase the water-holding ability of the skin through a collection of molecules called humectants. Humectants replenish the natural molecules your skin already has to provide normal hydration. Some of these humectants include lactic acid in products like AmLactin.
The second mechanism of maintaining hydration is to deposit oily material on the surface of the skin. The emollient will effectively cover and seal the moisture into the skin surface. The emollient will restore the impaired water barrier functions that are lost from repetitive cleansing.
