This my first time to review shower cream and the 1st though for me since need to review with rush then i decide to test out the PH Level. For my very basic knowledge for face skin is good to use product with PH level 4.5- 5.5 but not very sure about the body skin.
The result tested the PH level is 8. What is this mean, good or not good? so I had search some information on web and found some explaination of what is Skin pH and the Acid Mantle.
Skin pH and the Acid Mantle (Source)"Skin pH" is a chemist's term meaning "Potential of Hydrogen" and is used to measure the degree of acidity or alkalinity in the outer layers of the skin. It is measured on a scale ranging from 0 to 14 where the center of the scale, at 7, is neutrality (neither acid nor alkaline). A reading below 7 indicates that the substance being measured is acidic and above 7 is alkaline.
The acid mantle, the combination of sebum (oil) and perspiration, on the skin's surface protects the skin and renders the skin less vulnerable to damage. It also protects from attack by environmental factors such as the sun and wind and leaves it less prone to dehydration. Normal skin pH is somewhat acidic and in the range of 4.2. to 5.6. It varies from one part of the body to another and, in general, the pH of a man's skin is lower (more acidic) than a woman's. The acid mantle inhibits the growth of foreign bacteria and fungi causing the skin to remain healthier and have fewer blemishes. Acne, allergies and other skin problems become more severe when the skin become more alkaline.
The pH system works in 10-fold multiples and each pH unit represents a 10-fold difference in alkalinity. For example, a soap with a pH of 10.5 has 10-times the alkalinity of a soap of pH 9.5. "Mild" soaps are often alkaline (pH 9.5-11), and remove the natural acid protection as well as extracting protective lipids (fats) from the skin. Irritated and eczematous skins tend to have a more alkaline pH, and washing with soap can increase this alkaline state and make the skin even more vulnerable to irritation and infection.
