Application
The approach to restoring water to dry skin has taken three different routes.
1) Occulsion
2) Humectancy
3) Restoration of deficient materials which may be combined.
The first approach, occlusion consists in reducing the rate of transepidermal water loss through old or damaged skin or in protecting otherwise healthy skin from the effect of a severely drying environment. The second approach to the moisturizing problem is the use of humectants to attract water from the atmosphere, so supplementing the skin’s water content.
The third & perhaps the most valuable approach to moisturization of skin is to determine the precise mechanism of the natural moisturization process to assess what has gone wrong with it in the case of dry skin & to replace any materials in which such research has shown damaged skin to be deficient. Moisturizer’s often contain lipids & humectants of low molecular weight, humectants such as urea, glycerine, lactic acid, pyrrolidone carboxylic acid (PCA) and salts are absorb into the stratum cornium and their by attracting water, increase hydration.
PromaCare PCA-Na is the sodium salts of 2 pyrrolidone 5 carboxylate, It is one of the major Natural Moisturing factor (NMF) found in human skin. It is documented that sodium pyrrolidone carboxylic acid (PCA-Na) is used in hair care & skin care products with great effectivity as it is water extracting skin component.
As PCA-Na is the Natural Moisturizing Agent, it gives suppleness, humectancy & moisturizing property .It is being water soluble, therefore an oil in water (O/W) cream base decided to develop.
