What is your skin's pH?
The skin of your face has a pH of around 7.
Remember that pH is a measure of how acid or alkaline something is. The scale goes from zero (extremely acidic) to 14 (extremely basic).
As you'd guess, a score of 7 is neutral. Water has a pH of 7. So does milk.
Lemon juice is around 2 – acidic. Very alkaline or basic substances (the opposite of acidic) include ammonia, lye, and sodium hydroxide.
And as you'd also guess, these are not things you want on your face. Substances at either end of the scale are highly reactive, meaning they tend to have a chemical reaction with anything else they come in contact with.
