It is thought that pain results from a change in the pH of the fluid thar surrounds nerve cells. The fluid within your cells is slightly acidic, so a cut or burn releases this fluid and cause pain signals from your nerve endingd. What would you expect to find if you tested the pH creams and lotions used to treat cuts or burns?

lotions are base
all these costmetics like lotions ,creams & shampoos are manufactured for different purposes. the range of pH is between 6-8 .cream or lotions which are used to treat cuts & burns should neutral or slightly basic to prevent the growth of microbes.acidic medium is favorable for microbe growth

If the fluid around the cells is slightly acidic and you are normally NOT in pain, but when you get cut or injured you LOSE this acidic fluid and experience pain, but then when you apply a creme you don't experience pain again... I would assume the creme replaces the acidity lost when the fluid escapes, so the creme must be acidic.
